Yes, of course, it works the same way on all versions of UWTechnics HSS boards. If user chooses "Auto FP" in Nikon sync menu, it switches system to M mode automatically. When shutter speeds are in limit up to 1/250, it works by normal sync mono flash. If use 1/320-1/8000 high speeds, then system automatically switches to HSS mode.

Hardware is little bit different from previous boards. New HSS boards are much more powerful than previous, the LED output power is significantly increased. Such optical power is necessary for Retra Pro optical TTL input. Also, the firmware is new, it includes Retra Pro TTL profile and HSS support module. By the way, new TTL-Converter for Nikon (#11031-HSS) got updated TTL profiles of all other strobes too (Inon, Sea&Sea, Ikelite, Subtronic, Retra). This is totally renewed improved firmware.

Here are UWTechnics optional bulkheads specially developed for Seafrogs (Meikon) housings. These products (#91303-Optical, #91385-Nikonos, #91386-Ikelite style) have such a special rear part. So, uw strobes can be connected both optically and electrically to TTL system now.

In reality, Z240 charges 52 joule energy (from zero to Full) in 7-10 seconds. Yes, the "Ready" indicator lights after 2 seconds, this value is written in Specifications, but user has to understand that strobe gets just a partial charge in this time. The 2 seconds is usually a marketing value for this class of strobes, it refers to accepted energy level (50%, 60%, 70% or other, - but concrete level usually is not specified in Specifications).
