Tally input for 250u
 

Hello all, I am working on a setup that involves JVC 250u's switched through a Panasonic AV-HS400. I am trying to figure out how to feed the tally output of the switcher into each camera. My assumption is that the tally lights on the 250u's can be controlled by a couple of pins on the "studio" connector. Does anyone know what type of connector the studio plug is, and the pin configuration, or has anyone come up with a solution for this problem?

Enjoy the weekend!
