Serial I/O Port to Device Cabling
5-9
Following are cable diagrams detailing how to build your own cables
to go between a RJ port module and your terminals, printers, PCs,
modems, etc.
RJ-45 modular cable is the flat cable used for wiring telephones inside
of buildings. The cable is terminated at each end with a RJ-45
modular plug (connector) which is inserted into the modular jack of an
appropriate wiring module. Standard modular cables available from
Equinox (see www.equinox.com) are reversing. That is, the pins are
reversed on each end so that pin 1 on one end is connected to pin 8 or
10 on the opposite end, etc. Figure 5-13 illustrates the signals passed
through modular cables when connected to a PM16-RJ or CMX16-RJ
Serial I/O port.

If your operating system does not require RI or DSR, an 8-wire cable
may be used.
