Tally Connector 

 
Tally connections for camera's 1 through 8 are brought out on the nine-pin D connector 
marked TALLY. The pinout for this connector is shown below. Also shown is a typical 
wiring topology for using the MVS open-collector tally outputs. The tally connections 
function by providing an open collector output that provides a short to ground when 
selected (1/2 amp, 30V max.).
