Pelco C603M-A (11/07) Connecting A Ptz Device, Relay, And Alarms, Top Row, Bottom Row, Label

CONNECTING A PTZ DEVICE, RELAY, AND ALARMS

The NET5301T-I incorporates a 16-pin terminal block to support the following:

•PTZ device, such as a dome camera, using the Pelco P or Pelco D protocol (RS-422)

•Relay control, either normally open or normally closed

•Up to three alarm inputs, supervised or unsupervised, using any combination of high and low signals

The terminal block has tension clamps instead of screw terminals. Use a small screwdriver to open the clamp for a particular lead. Figure 14 shows how to wire the terminal block and connect it to the NET5301T-I.

NOTE: The terminal block is keyed. It attaches only one way to the video encoder.
