IF USING CHM22 CARDS
When using a CHM22 card the video for each camera is provided out the front of the card on BNC jacks.
The decoded video can be fed into other equipment as needed. Control data for a PTZ can be connected to the
2 pin jack on the rear of the CX254.
IF USING CXM22 CARDS
When using a CXM22 card the video from each of the four camera runs is routed to a single RJ45 jack
on the rear panel of the CX254 unit. Each card has its own RJ45 jack on the rear panel. Using a standard RJ45
cable you can then route the video signals on the copper backbone of the facility. Refer to the VIDEO PORT
chart below for pin assignments. Control data for a PTZ can be connected using the 2 pin jack on the rear of
the CX452.
