3.5.3 Controlling DTR with 72XX ACUs via Serial port
The information below briefly describes the connections for controlling a DTR from a
GDST 7200-series ACU.
1.
Using the connections matrix in Table 3-11 below, decide on a valid RS-232 or
RS-422 communications standard connection between the DTR and 7200. An
invalid connection is marked by an “X” and cannot be used. Note that DTR Port 2
can be used as either a RS-232 or RS-422 port, and that DTR Port 3 is RS-485
only and cannot be used with a 7200 ACU.
