Assembling a 9-pin D-SUB
Adapter for Serial 1
If you are connecting the Serial 1 interface on manager to a 9-pin D-SUB RS232 port on
a PC or control device, you need to use an RJ45 to 9-pin D-SUB RS232 adapter (see
Figure 8).
Figure 8
RJ45 to 9-pin D-SUB Adapter
A crossover Ethernet cable is used to connect the Serial 1 interface to the adapter. The
adapter in the following example is a female RJ45 to female 9-pin D-SUB. The arrows
indicate how to match up the RJ45 and 9-pin D-SUB connector pins described in
Table 11.
