ISTAKES
1. Failing to test the Cat5 cable assembly. It is easy to make a mistake when terminating the Cat5
cable with the RJ-45 connectors. Always use a LAN tester to check for continuity and shorts.
2. Using a Cat5 patch cable without all 8 conductors. Some Ethernet patch cables only have the 4
conductors (1,2,3,6) needed for Ethernet communications. These cables will not work as patch
cables for RS-232 communications. Visually inspect the clear plastic connectors to determine if
all 8 wires are present.
3. Using a null modem to connect the RS-232 port. The DCS MAXSYS Series panel connection
does not require a null modem when connecting to a
g!
system controller.
4. Failing to plug the Cat5 cable assembly into the correct port. Make sure the RJ-45 connector is
plugged into the same port (COM1, 2, 3 or 4) that is specified in the Configurator.
