Communication Cables
Watlow Anafaze supplies flat, oval cables with modular plug
and DB-9 connectors for RS-232. RS-485 cables have RJ12
connectors and bare-wire ends. These cables may be used for
short runs between a PPC and a host device or between a PPC
and a terminal strip or other wiring interface. When using
other cables or connecting over longer distances, select cables
and connectors that meet the standards described in this
section.
Do not use cables from sources other than Watlow Anafaze
unless the shield wire is in the proper position (pin 6) in the
connector. Table 2.27 and Table 2.28 on page 80 describe the
pin outs for the two connector types.
Cable Connector Pin Outs
Cable connectors must have the correct pin outs.
Refer to Figure 2.68 on page 79 to determine the location of pin
1 in the connectors. Refer to Table 2.27 on page 79 for RS-232
cable pin outs. Refer to Table 2.28 on page 80 for the RS-485 pin
out and connections. The colors in the table are for Watlow
Anafaze cables.
