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.

Table B identifies the pin assignments for the terminal block. An arrow on the rear panel identifies pin 1; on the terminal block, pin 1 is the 
left-most lead on the top row (refer to Figure 14).
