6.2 Installing RS232 Direct Communication Link
The 6200 DAS comes with a 10 ft (3 m) RS232 cable, terminating into DB-9 connectors. Refer
to Figure 6.7 for pin out and wire color information. During the lab checkout procedure (see
Section 2) you used this cable to connect the COM port on the 6200 DCP to the PC. However,
during this checkout you did not need to route the serial cable through conduit or a feed-through
gland. In order to use a RS232 communications link you may need to provide the cables and
connectors for this installation. The RS232 cable should not be run more than 100 ft. (30 m).

One installation possibility is to use a short run of cable from the DCP COM port to a weather-
proof communications junction box. The junction box should contain a terminal strip where you
can patch through the cable wires to the main cable. This cable is then run to the base station
hardware. You must carefully assess the potential problems with exposed cable and then decide
if conduit is appropriate for routing the direct communications link. Refer to Figure 6.8 below to
visualize one possible installation.
