Serial RS-422 connection
Serial RS-422 port may be used to connect OEM receiver with other ex-
ternal devices as well as connect two OEM receivers together for some
data exchange between them.
A Null-Modem RS-422 cable (not included in the Kit) with DE-9 Female
connectors on both ends and with length from 1 to 100 meters may be
used to connect two OEM receivers together. The DE-9 Female connec-
tor external view and pinout shown in Figure 2-4.
For best results, we recommend to use high quality STP 5 or 5e catego-
ry cable type as well as specialized for RS-422 applications cable types,
for example: Belden 9730, 9830 or similar.
The Serial RS-422 Null-Modem cable should be wired according to the
wiring table below.
