In Synchro Slave mode, my FS-4 will not connect to my Canon XL1 or XL2 camera. Why?
Two things could be causing this. 1. Make sure the camera has “DV Control” set to “On” or “Enabled”. In Synchro Slave mode, the camera must send a command through the DV port each time the camera’s “record” button is pressed. Unless this setting is made on the Canon camera, this won’t happen. 2. Use the opposite “power on” sequence than the one described in the FS-4 user manual (which works for most cameras). First turn on the FS-4 and set it to “Synchro Slave” mode. THEN turn on the Canon XL camera. This should allow the two devices to communicate, and control will be established from the camera.
