Hi,
Understand that FCB-RS Connector Interface Board is required for Sony FCB-EX Series Cameras.
See following link for this board:
https://www.ownta.com/fcb-rs-connector-interface-board-for-sony-fcb-ex-series-cameras.html?sef_rewrite=1
However, I cannot find any further information how I can use the pins connection on this board that indicated Z, F, I, C, G and 12V (see attached jpeg). What is the interfacing protocol used?
