  1. I have the NA-6400. I have not noticed AF hunting but regardless please set up the back button focus. It is a learning curve but it is also a game changer. You can prefocus on something and wait for your subject to enter the preset focus zone or focus before shooting but with BBF, when you push the shutter trigger and the camera goes click, focused or not. No wait. Set to single shot to start with and also turn off AF tracking. It seems my camera, if I keep the BBF engaged (pressed) the focus tracks, when I release the BBF it locks there until I focus yet again or the power is cycled (and possibly sleep).
  2. The cooler bag came from Sam's Club (Walmart) which is like Costco. It has foam padding about 1/4 inch thick. It cost about $5 give or take. There are more expensive bags but they are heavier and harder to pack. The bag can transport my assembled NA-6400 with WWL and strobes and doubles as my own private wash tank. Cheap and light, buy several, throw them away when they come apart. I do put an extra piece of foam or a microfiber towel below the camera for extra protection.
  3. I found those somewhere and thought them useful. I run my optical cables through them, the coil section fits nicely through there and keeps the cables secure without damaging them.
  4. The weight of a Nauticam NA-6400 with two Nauticam (70X200) float arms and two Inon strobes minus the Nauticam WWl-1 but otherwise ready to go diving is 11 pounds and 11 ounces. (as below): In the Pelican case the rig is under the 25 pounds carry on limit, including WWL. But the strobe arms and camera and camera lenses are distributed among other luggage: Edit to add, the WWL is 2.7 pounds in air. Underwater, with the WWL-1 with float collar installed, the entire rig is but a few ounces, slightly negative. With the CMC-2 macro converter the rig is neutral, maybe even slightly positive (as well with the dome port and 16mm pancake lens with fisheye converter) but the Stix floats remove easily for fine tuning.
  5. For what it is worth. I have always jumped in with my camera and occasionally reenter with my camera (clipped to my chest strap D-rings and scooter/crotch ring). But usually I hand it to a deck hand who I try to discuss with them my preferences beforehand. Most times they do their best to accommodate. I provide instruction to NOT put my camera in the "camera bucket" but to instead place it in my soft cooler bag (Sam's Club). Giant stride entries from normal heights are easy, I can raise the camera as I enter to reduce shock to the system. Upon return, the crew is going to grab anything and everything they can quickly. Usually a strobe arm despite my pointing to them where I wish for them to lift. So, I bought a Nauticam braided piece that I clip between my strobe arms and the crew automatically goes for it. Happy day! Here you can see the two bolt snaps on the arm joints for connecting to my chest D-rings and the small tether and bolt snap on the handle for the scooter ring. The deadman (blue) tether is connected as I step to the platform and disconnected as the crew takes my camera upon reentry to the boat. The Nauticam handle (white) is clipped to a D-ring during the dive and upon dive completion, I rotate the strobe arms up, clip the two arm bolt snaps together and attach the Nauticam handle for the crew's target fixation need. I also have the two silicone elastic bands (could be 4mm bungee even better) from the strobe clamp to the lower arm clamps. This ties the camera rig together (for both entry and exit). I have had cameras dropped into the ocean, I have had water contact optics knocked off by crew mishandling, I have had strobe arms disconnect, I have had domes scratched. So, I try to eliminate those things by discussion before hand and my rigging of the system. I keep my WWL-1 port cover with me, clipped off to my scooter ring, it is on during entry and exit. Your system will get some scratches and scuffs during use, otherwise leave it at home, diving is rough. Not to mention the scuffs and scratches on me! I will say, with my camera clipped off to my chest D-rings and scooter ring, I can usually reenter the boat via a ladder with the camera as long as it is not too rough. If the ladder is slamming up and down, best to hand off to the deck mate.
  6. If you explore the Inon web site you may find manuals. http://www.inon.jp/customer/discontinued/d2000/top.html If your flash trigger emulates the Sony always on pre-flash then you will need to install the magnet. If your flash trigger ignores the pre-flash and fires only a single pulse you will need to remove the magnet. In the sTTL mode the magnet switch is irrelevant, in External Auto and Manual it must be used to set the strobe to the camera pre-flash or no pr-eflash. The Sony A6300, like my A6400, always fires a pre-flash even when the camera is set to manual mode. J INON D-2000 Underwater S-TTL Strobe User Manual [Basic manual] This manual is translated and rewritten the INON D-2000 manual , Japanese version by Yuzo Kanda. So if you have any question, comments or suggestion regarding this manual then do not ask to INON Japan or INON America Inc, please contact Yuzo Kanda (Naturephoto KANDA Co.ltd / uwdigitalcamera.com) info@naturephoto.co.jp http://www.uwdigitalcamera.com Please read this manual through and the manual of your camera and housing before you use. [ Safety Precautions ] Please read the following precautions carefully as they contain highly important information related to personal and product safety. Precautions designated “WARNING!” refers to those situations, which could result in serious injury or death. Precautions marked “Danger” or “CAUTION!” refers to those situations or conditions, which could result in personal injury or property damage. Please observe all precautions Do not disassemble or remodel D-2000. The strobe contains very high voltage circuitry, it could lead to severe electric shock and injury. Never touch electric circuit Even if it is not installed battery, there is the possibility to get an electric shock. When you think it flooded or malfunction, stop using underwater or even on land immediately. On this case, please remove batteries ASAP and request to repair or service to us. Do not drop water or a foreign body in the battery box. Do not fire the strobe at near face ( Especially , take care of infants) Do not fire this strobe with the reflector placed on a table or the floor as that may cause overheating of the internal circuitry and/or fire. Do not use any solvent or other chemical to maintenance or cleaning. Keep this product out of the reach of babies, infants and children. !Danger Safety precautions about battery. Follow these precautions to avoid damage to batteries and strobe, and depending on the type of batteries, possible buildup and explosion of flammable gas. 1 ・ Do not use non-specified batteries You can use these batteries. a) AA Nickel Metal Hydride battery (1.2V) * recommended b) AA Nicad battery (1.2V) c) AA alkaline battery (1.5V) d) AA Lithium battery (1.5V) e) AA oxy ride dry cell battery (1.5V) * Battery voltage of the oxy ride dry cell battery, there is 1.735V. So do not turn on built in focus light before their voltage is lower than 1.5V. Usually it will drop down to 1.5V with over 20 times flashing at Full position. ・ Do not mix different battery types, different manufactures or batteries having different remaining charges. ・ Do not attempt to charge non-chargeable batteries. ・ Make sure battery +/- positions are placed in Battery Box. ・ Do not intentionally short the batteries or circuits. ・ Do not use battery charging devices that are not compliant with the battery manufacturer’s recommendation. !Caution ・ Never repeatedly fire the strobe continuously, for example, to test, discharge or refresh the batteries. ・ If you use this strobe in air plane or near the medical equipment, please follow the instruction of them. ・ Protect the D-2000 from excessive impact shock and vibration. Do not drop, do not leave on a vibrating boat deck. Especially, protect the Optical sensor. ・ Do not leave the D-2000 exposed to direct sunlight or other areas of high temperature. ・ Do not leave the strobe closed when traveling to or from high altitudes. Always remove the battery cap or O-ring. ・ Please remove batteries after using. ・ Violent impact can severely damage it, and don’t “Back roll” or “Giant stride” with D-2000, please take it hand to hand. [ Before Use ] The D-2000 strobe is a dual use underwater and land external strobe with G.N.20 (ISO100, Air) and following main futures. ・ Underwater TTL auto exposure in S-TTL, from high-end digital cameras to point-and-shoot digital cameras. ・ 24 steps External Auto control mode and 13 steps manual mode. ・ Film camera’s TTL mode is supported. ( Nikonos type is compatible, but it is required “optical signal converter TTL” and optical cable) 2 ・ Integral Shutter linked Auto off Focus light is installed. ・ Clear photo system to completely block all visible light from camera’s built in strobe, so you can take more clear images without “backscatter”.

Main mode switch You can set S-TTL mode, S-TTL “Low” mode, External Auto Flash exposure Adjustment mode or Manual mode. 12. Strobe ready lamp (Red) When the strobe is ready for flash, it light on Red lamp. 13. TTL monitor lamp (Green) When D-2000 could controls its power correctly with S-TTL, S-TTL ”Low” or External Auto mode, it light on Green lamp. 14. EV compensation dial When you use D-2000 at S-TTL or S-TTL “Low” mode, it works as the EV compensation set dial. And when you use D-2000 at External auto mode, this dial works as Aperture value set dial, and when you use D-2000 at manual mode, it works as the power control set dial. 15. Advanced Cancel circuit switch ( magnet switch hole) When you use D-2000 with the camera that do not pre-flash and at External mode or manual, set the magnet here. Then the advanced cancel circuit will be OFF. 16. Focus light switch Off mode: position set at “Light” as in picture, Single mode: Push this switch once and release. The light will turn on and then turn off automatically as the internal Flash tubes Focus light Light adjustment sensor +1/4EV compensation Switch Slave sensor Battery box Battery box Inner cap Battery box Inner cap screw Battery box outer cap 6mm threaded socket for Z adapter or YS bolt 5 strobe fires or if shutter not released, after about 8 seconds. Continuous mode: By pushing switch and turning it to either right or left “Lock” position while pressing, then the focus light will turn on and shine continuously until the shutter is released. Then the focus light will turn on again automatically 0.5 seconds after the image is captured. When you use the focus light at “continuous mode” it will turn on again automatically, and the off time is approximately 0.5 seconds, at the case of using slow shutter speeds it will turn on again while the shutter is still open, exposing the image with light from the focus light. So please use “Off mode” or “Single mode” when you use slow shutter speed. Measures to prevent accidental Flooding The D-2000 is waterproof due to a rubber O-ring that seals the internal circuitry from the elements. There is only one user serviceable O-ring: the Battery Box O-ring. This O-ring requires frequent inspection and care to ensure its watertight integrity. Since most flooding occurs due an O-ring related problem we strongly recommend you to Inspect the O-ring (and clean, grease or replace as necessary) each time before using the strobe.. O-ring inspection locations and methods Inspect and maintain these three points: The O-ring itself O-ring contact surfaces O-ring grooves and Battery Box outer cap O-ring contact surface If O-ring is properly seated in groove Grease First, inspect the O-ring as it is seated in the groove. There is a high chance that the strobe will flood if placed in water if any of the following are evident. If hair, sand or other debris is attached to the O-ring. Remove O-ring and wipe-off the debris. If the O-ring is cut or cracked. The O-ring must be removed and replaced with a new O-ring 17. Focus light filter seal When you use S-TTL or S-TTL”Low” mode, paste this on the window at focus light. This filter prevent the focus light have an effect on the accuracy of TTL control. And it makes easy to close fishes or else , they are sensitive to light. 18. Magnet screw tightener 19. Magnet 20. Magnet switch screw 21. INON grease 22. Battery box spare O-ring 6 If the O-ring is twisted. The O-ring must be removed and reinstalled uniformly with no twists. If there is hair, sand or other debris on the O-ring contact surfaces. Wipe of any debris If there is a scratch or other imperfection on the O-ring contact surfaces. The strobe must be inspected by an authorized technician, and repaired if possible. Contact us. O-ring Maintenance Method Grease: INON O-rings are compounded with a special type of oil that is not compatible with all grease types. Do not use the grease except the supplied INON Grease. If you use any other grease, which may cause the O-rings to swell or deform, causing poor seal and water leakage. If you use non-INON grease , then please replace the O-ring to a new one as soon as possible. O-ring and sealing surface should be lightly lubricated with INON grease lubricant on a regular basis. This should always be done before storing the strobe and before a first dive after taking the strobe out of storage. It is important never to use a sharp instrument when removing an o-ring as this may cause damage to the o-ring or the o-ring groove. A hairpin or a credit card works well. The removed o-ring should be examined for damage. Check to make sure that the o-ring is free from nicks and cuts and that it retains its original round profile. O-rings that appear to be damaged should be discarded immediately and replaced with new o-rings Clean the o-ring grooves (where the o-rings sit) with a Q-tip. Be sure to remove any lint the Q-tip may leave behind. Inspect the groove and the O-ring contact surfaces for damage. Wipe the part of the battery cap that the o-ring seals against with a clean lint free cloth. Re-grease the o-rings with a thin layer of INON grease until it appears to be smooth and shiny. Do not over grease it use just enough grease so that the o-ring will pull smoothly through your fingers. Excessive amounts will only attract dirt to the o-ring. Replace o-rings in its proper position. After Installing O-ring After Installing the O-ring in the groove, making sure that it is seated uniformly and not twisted. Then add a little extra grease to the O-ring and liberally grease O-ring contact surface on the battery box. A Iittle extra grease is necessary due to friction when screwing down the battery box cap. too much friction. When the battery box cap is fully screwed down and seated on the O-ring surface, Iook at the O-ring through the transparent edge of the cap. You should see a continuous, uniform contact line between the cap and O ring. If the contact line is not uniform, or twisted, contaminated with hair, Iint or sand etc. there is a good chance the strobe will flood. Remove cap, re-seat O-ring and remove contaminants as necessary. 7 Chapter 1 : Before use About corresponding camera or strobe system INON D-2000 is a complex, multi-function device with different futures available for 6 kinds camera, strobe or housing systems, and it has 4 ways to control its power. In this basic manual, it is instructed how to use with digital cameras ( Pre-flashing type or Non pre-flashing type) The other way to use as a slave strobe or with housing, they will be instructed in the “advance manual” 8 About the batteries The D-2000 can use the following batteries.( Batteries are not included in D-2000) AA type Alkaline batteries x 4 AA type Nicad batteries x 4 AA type NiMH batteries x 4 AA type oxy ride dry cell batteries x 4 * Caution 1 : Do not use other kind batteries with merge. We recommend to use with same manufacturer, same kind and same model batteries. And if you use oxy ride dry cell batteries, Please read followed caution. The recommended battery is NiMH battery. Caution 2 : The electric current of the oxy ride dry cell battery is same as the alkaline dry cell, but at survey value (as for oxy ride dry cell battery itself inscription 1.5V) there was 1.735V regarding the voltage plane. So if you turn on the focus light of D-2000 when its voltage is still high, it makes easy to burn out light bulb. To prevent it, please turn on the focus light after the battery voltage is low. ( about 20 times or more full flashing make its voltage lower than 1.5V) ・ Do not mix different battery types, different manufactures or batteries having different remaining charges. ・ Do not attempt to charge non-chargeable batteries. ・ Make sure battery +/- positions are placed in Battery Box. ・ Do not intentionally short the batteries or circuits. ・ Do not use battery charging devices that are not compliant with the battery manufacturer’s recommendation. When you do not use D-2000, please remove batteries. And it depending on the type of batteries, possible buildup and explosion of flammable (hydrogen) gas. IF you ever feel suspicion that the D-2000 is not operating correctly, immediately stop using D-2000 and remove batteries promptly. And request to repair or service to us. 9 Optical cable INON supplies these optical cables. Installing Batteries When you install the batteries, always turn Main mode switch to OFF Slowly unscrew the Battery box outer cap counterclockwise. Unscrew the Battery box inner cap screw counterclockwise and remove the Battery box inner cap. ( at this time please be aware not to lost the inner cap screw) Install the batteries in proper position, Pay attention the indications of + / - inside of the battery box. Put the inner battery cap and screw down the battery box inner cap screw. After checking the O-ring and contact surface, slowly screw down the battery box cap clockwise. Do not turn on main mode switch before installing the optical cable. Connecting the arm and the optical cable Optical cable kit W5 Optical cable kit W12 Optical cable kit W11 Optical cable kit W13 Optical cable kit W14 M67 adapter for DC20 AD mount adapter forCP1 AD mount adapter forCP2 AD mount adapter forFX701 AD mount adapter for PHB 10 Attach your arm to the D-2000, please use “Z-adapter” or “INON YS attachment bolt kit”. If you will not use proper attachment tool or use some other length bolt, it may break the mount base of D-2000. Connecting with “Optical cable D” , and D-2000 requires “ IR filter seal” to control its power with “S-TTL” mode. And when you disconnecting arm or cable, turn off main mode switch for your safety. Chapter 2 : Easy using ( S-TTL mode) S-TTL control D-2000 strobe achieved "Real TTL" control with most digital cameras. From high-end cameras to point-and-shoot cameras, it works TTL auto exposure, programmed mode or other modes, that you should do is only shooting. At the present (Oct.2004) INON had confirmed the “S-TTL” compatibility with these cameras How to use S-TTL 1. Paste the Red filter seal of the focus light. Do not set flash mode at “Red eye reduction mode”. And there are some case that it is impossible to use enforce flash mode by your camera. ( EX: it is impossible to use enforce flash mode with Canon IXY digital series cameras except Manual mode.) Please refer the instruction of your camera. 3. Turn on main mode switch and set it to “S-TTL-Low” mode 11 4. Set the “EV controller dial” at position “B” Using the focus light and confirm the strobe light beams to the object correctly. And this light helps speedy focusing. And shoot the images. At almost case, you will have good result that is well controlled strobe light. So it is no need to adjust any more. But the accuracy of S-TTL control depends on it of the built in strobe. So if you use D-2000 with a point-and-shoot camera that strobe control accuracy is not so good, on this case it will be need to adjust the EV compensation of D-2000. Adjustment of the strobe power at S-TTL mode INON D-2000 has the EV controller dial. There are some case that you have better to control the strobe power with this function by the reason of “strobe control accuracy of your camera”, “situation of imaging” or “ your favorite” and else. INON introduced some cases, it will be need the adjustment of the strobe power. Case 1: Camera: Situation Result: How to adjust the source of the trouble Case 2: Camera: Situation Result: How to adjust the source of the trouble OLYMPUS μ -series Macro mode “ON” and using tele zoom, and the working distance 30-40cm or closer. Over exposure ( too bright ) Set your strobe mode “S-TTL Low” and adjust the power with the EV controller dial if it is need. At this situation and with this camera, the aperture is closed to f14 and the built in strobe flashes Full power. And this camera controls its exposure level with changing the sensibility of CCD. So S-TTL system can not detect the stop signal of the built in strobe power and D-2000 flashes with Full power, too. And the result is over exposure. But if you use "S-TTL Low" mode, then D-2000 flashes with the same power with the built in strobe Even if the built in strobe flashes with Full power, but D-2000 flashes the same power of the built in strobe. OLYMPUS μ -series Wide angle, and in enough ambient light. Ex. backlight photographing. Under exposure ( too dark ) Set your strobe mode “S-TTL ” and adjust the power with the EV controller dial. Or changing the ambient light condition, or a little zooming up and use closed aperture. At this situation and with this camera, the built in strobe flashes with a slight power. Even if the camera strobe mode is " enforce mode " but it only do pretend flashing. So S-TTL system detect the slight power of the built in strobe power and D-2000 flashes with a slight power, too. And the result is under exposure. And the captured image is like a exposure with only ambient light 12 How to Adjust exposure level 1. Use EV controller dial : Position “B” [± 0] ,turn to “A” side then [ + ] compensation, and turn to “C” side then [ – ] compensation. [+] compensation: 3 steps [ – ] compensation : 5 steps (the range surrounded by Yellow arc ) 2. Select to use “S-TTL” mode or “S-TTL Low” mode “S-TTL Low” is the standard mode, but if you think it will be under exposure then please use “S-TTL” mode. a) When you use D-2000 at “S-TTL Low” mode and using EV controller +3, but it is still under exposure b) When you use diffuser panel. c) When you use closed aperture. At these case, please use “S-TTL” mode. 3. You can use the EV compensation or strobe power compensation of your camera. Adjust strobe power to [–] compensation (over exposure and adjust it to dark) You can adjust the power to –5 step Adjust strobe power to [+] compensation (under exposure and adjust it to bright) You can adjust the power to +3 step If you could not have proper exposure by this control, then turn mode switch to “S-TTL” mode. And when you use “S-TTL” mode, you can use EV controller dial with the same way. Do not fire D-2000 continuously over 15 times, if you need to fire D-2000 continuously, then once stop photographing and cool down the circuit for over 3 minuets. 13 Trouble shooting If your D-2000 suddenly stop charging, there is a possibility the trouble of inner battery cap with the batteries that you use. Please cope as follows. If your battery terminals on the inner cap are crushed, Then pull up the terminals and secure the contact. And still it does not work, then there is a possibility it is caused with dirt of the contact face. ( battery side or inner cap) It depending on the type of batteries, possible buildup of flammable (hydrogen) gas . And the battery box of D-2000 is highly sealed. And it build up residue on the battery terminals and battery box terminals. This can cause poor connection, so clean the terminals as in images below. At this case, please take care not to adhere alcohol or silver polish on plastic parts as the battery box or else. Chapter 3 : After care and maintenance About handling ・ Never repeatedly fire the strobe continuously, for example, to test, discharge or refresh the batteries. ・ If you use this strobe in air plane or near the medical equipment, please follow the instruction of them. ・ Protect the D-2000 from excessive impact shock and vibration. Do not drop, do not leave on a vibrating boat deck. Especially, protect the Optical sensor . ・ Do not leave the D-2000 exposed to direct sunlight or other areas of high temperature. ・ Do not leave the strobe closed when traveling to or from high altitudes. Always remove the battery cap or O-ring. This strobe is strong against external pressure but it is not designed to withstand a build up of internal pressure. You must loosen the cap of battery box before taking D -2000 on board aircraft. ・ Please remove batteries after using. ・ Do not disassemble or remodel D-2000. The strobe contains very high voltage circuitry, it could lead to severe electric shock and injury. ・ Never touch electric circuit Even if it is not installed battery, there is the possibility to get an electric shock. ・ When you think it flooded or malfunction, stop using underwater or even on land immediately. Wipe each terminal surface with a Q-tips or cotton swab soaked in alcohol to remove any residue or oil similar. If this step does not fully clean the terminal, dap a small amount of silver polish on a Q-tips or cotton swab and wipe terminal surface until clean. And clean off any silver polish residue with a clean swab. 14 On this case, please remove batteries ASAP and request to repair or service to us. ・ Do not drop water or a foreign body in the battery box. ・ Do not fire this strobe with the reflector placed on a table or the floor as that may cause overheating of the internal circuitry and/or fire. ・ Do not use any solvent or other chemical to maintenance or cleaning. ・ Please take care about handling of batteries ( refer page ) Post dive care After using D-2000 under water, be sure to wash it thoroughly with fresh water, while leaving all caps on waterproofing components closed. After washing with fresh water, wipe it with a dry, soft cloth and dry in the shade. After using, remove batteries from the battery component. When removing them, wipe water away completely so that water drops will not get into the component or terminal plate. Apply a thin coat of grease over the O-ring When not using for a prolonged period of time, store unit with care away from high temperature, high humidity, direct sunlight, or severe cold. And the cap of battery component is removed and sealed in zippered airtight container or in something like this. When not using for a prolonged period of time, please recharge and test flashing D-2000 once in a month. Then you can maintain the Condenser of D-2000 in good condition. Never use petroleum solvents, such as thinner, to clean the D-2000. Overhaul and Maintenance service We recommend the maintenance at a fixed time. The periodical inspection, once for 1 years and the overhaul, once for 3 years. And if you use D-2000 frequently, then it is better to have in shorter. About Maintenance, please request to us. And INON D-2000 has warranty for a year from the day you purchased. But this warranty is valid only in Japan. So For warranty work, the item needs to be shipped back to Japan. In principle, when item is purchased from us, the full Japanese warranty applies. However, if it is shipped to Japan for repair or maintenance, the owner must bear transport ation costs to Japan.

  7. Or just order the magnet set, one per strobe and maybe a spare set, for the D2000/S2000 and remove the switch from the Z240. The allen screw can be sourced at a hardware store or again from Inon.
  8. Chris and Tim, thank you both. If I seem cranky, it is not you guys, it is me, I am getting frustrated. But I may be making some progress, at least at understanding what is going on, thank you both. Chris, I did your set up and the A6400 using the onboard strobe works fine. The Inon strobes produce a pre-flash and properly sync in sTTL mode and in Manual mode with the magnet switch removed I get good sync. I see two flashes when I use the rear curtain sync and slow shutter. In both strobes manual and sTTL I am able to control my exposure from light to dark using the strobe power dial and as well in sTTL mode using the camera +/- EV flash control. When shooting my strobes in manual mode I run the EV control down to -3 stops to conserve battery power. Since the Sony cameras cannot cancel the pre-flash I just have to live with that when using the onboard flash as the trigger. But functionally it is fine. I will contact Pavel, I am just trying to get to the facts and was hopeful others had some direct experience as well to give before I contacted him. This being my second board, both with a similar issue, I am concerned.
  9. Tim since you ask as did Chris, let me respond to you both in regards that question. Why would I not seek the experiences of other A6XXX camera users with the UWT trigger? Why would I not and why would it be expected that I would not? I am not understanding why I am being asked this? Is this not a legitimate forum topic? Further, I will contact Pavel, a super nice man. I wanted to have more knowledge on my part before contacting him a second time. Yes, as I indicted up thread, this is my second UWT trigger. The first trigger had two failure modes: 1. The first trigger would randomly going into an uncontrolled firing mode and would not stop firing until I cycled camera power. 2. The first trigger also had the same or similar issue I am having with my second trigger that I started this thread over, random failure to drive my strobes. In the first trigger I never explored this issue much but it does seem to be the same issue I have with trigger number two. I was just distracted by the larger issue of my strobes firing continuously, that sort of got my attention as it would yours. I was incorrect, in my earlier saying it was a failure to sync, it is a failure to sync because the LEDs do not fire so of course my strobes do not fire. I apologize for that confusing distraction. As I dig further into this problem I understand more. I am sorry, if the threads I started are inappropriate please have them deleted. I was interested in and requesting experiences of other users with this product, I thought that was a reasonable quest. James
  10. Okay, here is what I did. I removed the camera from the housing. I also then removed the UWT board from the housing by gently prying it out. I affixed it atop the camera and then pointed the camera at a mirror. And predictably, about every sixth shot, give or take, randomly, the LEDs do not fire and are not visible in the photo. When all is working well the LEDs are clearly visible in the shot. I guess I am the only person with an A6XXX camera and UWT board, lol. I would be curious if others have the same FTS at random times? I would be challenged to believe my camera is defective. I just think it not to be a stable operating condition, that being using the WL command to ignore a pre-flash via trigger board firmware. I could almost ignore it except that sometimes it will do this two or even three times in a row and then a string of good shots. The "one" shot will of course be the one the malfunction occurs on and therefore is unacceptable to me. So, I was incorrect, the board is NOT firing and I thought it was. You would think this easy to verify but it is not apparently for me. It is not perhaps a failure to sync but a failure of the board to fire the LEDs.
  11. Still working on thsi Chris. One thing, rear curtain sync is not available with the WL command on. With the magnet installed I am getting a single flash from the strobes, not two. Best I can determine, I get a single flash but when the FTS occurs, that single flash is simply not occurring when the shutter is open. I will get six or seven good exposures, then a badly under exposed, ambient only shot. Strobes in Manual Camera in Manual WL command on Magnet installed Flash Fill setting I am beginning to think that the WL command is simply not a stable camera setting or not stable in the UWT board. For whatever reason, the camera does not issue the command or the trigger ignores it and the UWT board is firing the strobes out of sync as a result. I am very confused.
  12. I split this topic from my other thread to prevent confusion of myself mostly. I have an A6400 in a Nauticam NA6400 housing, currently shooting with aging but fully functioning Inon D2000 strobes. I am looking to purchase, in due course, new Inon Z330 strobes. I would like the option of using a good old fashioned X-sync connection. I think I see the parts needed on the Reef/Nauticam websites to install the hotshoe and bulkhead connectors. Of course, the D2000 strobes are optical only, I am planning to the future for a Z330 so understand that. In other words, I want to be able to use wired, hot shoe, X-sync when I feel like a nut and revert to optical sync when I do not feel like a nut. And I do have a reasons, one for example, I want to be able to extend my dives or number of dives between battery changes and the A6400 triggering strobes with optical sync and the onboard camera strobe unit uses more battery power than would a wired Hot shoe X-sync as the camera strobe is disabled when the hot shoe is connected and/or the flash head stowed. The other, I would really like ot avoid the always on pre-flash. The A6XXX series does not have a way to cancel the pre-flash using the camera strobe as an optical trigger. My first question is therefore, when using a hot shoe activated electrical X-sync connection, does the Sony A6XXX series cameras, specifically the A6400, still fire a pre-flash? I do not have the equipment to test this currently thus the need for an experienced answer. My second question, for now, if the A6400 still fires a pre-flash using a hardwired X-sync hot shoe flash, can the Inon Z330 (or Z240) strobes be configured to ignore that first flash? Thank you in advance for any help.
  13. I have not done your experiment yet, I had to go into work but I will. That is a good thought. But, to answer, I am interested in a manual only (which most photogs prefer) electrical solution that does not use the UWT board because it is not, thus far, reliable. So I am looking to do something other than a flash trigger board. This being board number 2, different issue on the first one, I have sort of lost faith given the cost of the unit. It is not my camera and if it were a firmware issue on the Sony side, whatever that might be, the trigger board is going to have to work with that because Sony will not address such an issue with a niche UW flash board. The problem lies with the board, my camera is not faulty. I find a one FTS in six average not an acceptable outcome. Using the camera strobe, as Nauticam intended, works fine, I just wanted a way to trigger without pre-flash and and without the battery drain of the onboard flash as a trigger. Functionally it works great in manual, manual with strobe TTL and full TTL. But I like the concept of the board. I see the parts I need on the Nauticam and Reef sites for wired electrical X- sync.
  14. Okay, I see, I will try that tomorrow, good thought. Thank you. Off subject, I may purchase new Z330 strobes at some future point. Since they have wired/electric sync capability (as does the Z240) what do I need to run them as such with my A6400 Nauticam?
  15. Mr. Chris, thanks for the thoughts. The WL command is used by the firmware within the TTL converter that sees the WL command to not pre-flash. The "0" position on the converter switch is irrespective of the type of strobe as it is a hard wire manual. I have available to me an S2000 strobe and the issue does not go away. The operation of the S2000 and D2000 are very similar. The "9" position is for the TTL operation with the S2000 in the sTTL mode. Of course, I am running twin D2000 strobes, but this is not really the cause of the problem. When I say underexposed, I was not clear, thank you for pointing that out. You are correct, in a mirror, there is no visible flash when the condition occurs. The condition is random, I do not seem to be able to tie it to anything in particular. The converter and camera work fine, and then loss of sync. Fire again, it is good! I am beginning to think you might be on to something in that occasionally the converter does not see the WL command. The Sony onboard strobe cannot be configured for 1/16 power nor can the pre-flash be cancelled (thus my desire for the UWT trigger). The UWT trigger is a hot shoe connection, the camera strobe is out of the system so setting it to a low power is of no point. The apparent brightness of the D2000 strobe does not visibly differ when the failure to sync occurs. Of course not because the strobe is in manual setting and the power setting is what I dialed in. It just simply is not in sync when it fires on random occasions. The position "9" for sTTL does work with the strobes in sTTL position and I am able to control the exposure and I can also revert the strobes to manual and again control the exposure but in both cases, I still get a random failure to sync. Forgive me but I am thinking through as I write. I am afraid I will burn my strobes up just banging away trying to isolate each setting to isolate the problem. I cannot isolate the problem, that as much as anything is frustrating. I do not wish to blame it on the converter, but, right now, it is suspect number 1. The good news is that the system, with the UWT converter disconnected, I can revert to the A6400 strobe and all is well in both full manual (strobe and camera) and manual camera and sTTL strobe.
