CAUTION:
Do not operate the system without Digital module covers. They
are required to protect the equipment and to meet international regulatory
standards. Do not substitute other covers as they may not meet the required
specifications.
7.1 Connecting Terminals and Serial Printers
You can connect up to 16 terminals and/or serial printers for each CXA16 or
CXB16 module installed in the system. If your site was prepared properly,
the lines for the additional terminals and printers are clearly labeled and
terminate near the system.
• You do not connect the terminals and printers directly to the system,
but to a cable concentrator (H3104) that has connections for up to eight
terminals and printers.
• You then connect the cable concentrator to the system with a BC16D
cable.
For each CXA16 or CXB16 module, two H3104 cable concentrators and two
BC16D cables are shipped with your system.
To connect additional terminals and printers:
1. Find an H3104 cable concentrator and a BC16D cable.
2. Feed one end of the BC16D cable under the system from the back or
side and insert it into the connector as shown in Figure 10.
• If you are connecting two BC16D cables, connect the first to the
connector labeled 8–15 on the module cover.
• If you are connecting one BC16D cable, connect that cable to the
connector labeled 0–7.
Lock the connector in place by using the bail latches.
