Hi guys,
@ hoppichler, the only cam you can use with an external TTL strobe by wire connecting in PT22 is the c770 because the C765 / C760 has no strobe plug . The C765/760 is only usuable with optical slave systems the C770 you can use with the Olympus FL20 in its housing or .... with the MH / Mikedive solution for the PT 20,22,23 housings and all Sea and Sea strobes ( without the YS25) and the Ikelite DS125 and the Inon Z220 ( the pilot and laser switch comeing soon..... we hope (:-) )
