The Westcott 8"" Male PC Sync to Female Mini ( 3.5 mm) Cable allows FJ Wireless Flash System users to manually communicate with various brands of speedlights equipped with a PC Sync port. The PC Sync Cord is designed for connecting an FJ-XR Wireless Receiver to a speedlight equipped with a PC terminal for transmitting FJ Wireless communication via the FJ-X2m Wireless Trigger. This cable reliably expands the FJ Wireless Flash System and eliminates the need to utilize a speedlight's optical sensors to capture your images. To connect simply attach the cable's male PC Sync end to a speedlight and plug the FJ-XRs pin into the cable's 3.5 mm female port.
The speedlight can then be triggered via the FJ-X2m wireless transmitter. Its that easy.
