Installation Manual, publication 1785-6.6.1, and the installation data for
the I/O modules that you have selected for more information on I/O wiring.
Also, see Allen-Bradley Programmable Controller Wiring and Grounding
Guidelines, publication 1770-4.1, and Control, Communication and
Information Reference Guide, publication ICCG-1.2, for more information.
Programming Terminal
The cable that you use to connect a processor to a programming terminal
depends on the communication device used. Table 2.P lists the cables that
you need for different configurations.

You can also use a 1770-KF2/B communication interface to connect to a
PLC-5 processor. You build your own cables to connect your
programming terminal via the COM1 or COM2 serial ports to the
1770-KF2/B. For the cable pin assignments, see the Classic 1785 PLC-5
Programmable Controller Hardware Installation Manual, publication
1785-6.6.1.
