bike_rider 0 Posted May 28, 2007 I want to connect the CW964 to the Geovision. GV only uses two wire control, while the CW964 offers the option of 2 or 4 wire protocol. My question is, which two wires on the CW964 connect to the terminals labeled + and - on the GV card? Share this post Link to post Share on other sites
blowrabbit 0 Posted May 29, 2007 If you have 2 wires from your dvr they would be "transmit" pair. You would run these into the Panasonic "receive" pair which is yellow and green. There is no standard for +and - for rs 485 pano uses A and B. Usually A is +and B is -. Share this post Link to post Share on other sites
