•
Connect the female connector (9-pin or 25-pin) on the opposite end of this cable to the male
RS-232 connector (serial port) on the selected programming (or other serial) device. If you
build you own cable, use a connector that is compatible with your serial device.
•
Notice that both ends of the 6-foot RS-422/RS-485 compatible cable are the same; a 15-pin
male connector is attached at both ends. Connect one end of this cable to the 15-pin female
connector on the RS-422/RS-485 connector on the converter.
•
Connect the other end of this cable to the 15-pin female connector, which interfaces to the RS-
485 compatible serial port on the Series 90-30 or Series 90-70 PLC. For the Series 90-30 PLC,
this connector is accessed by opening the hinged door on the power supply. The serial port
connector for the Series 90-70 PLC is on the CPU module, and is accessed by opening the
hinged door on the module.
Cable Description
The serial connection to the Series 90-70 PLC (see Figure B-1) is to the RS-422/RS-485
compatible serial port connector, located at the bottom of the CPU module behind the hinged door,
through a 6 foot (2 meter) serial interface cable, IC693CBL303. Wiring information and
recommended cable and connectors are provided for those who may want to build their own cable
having a different length.
The serial connection to the Series 90-30 PLC is to the RS-485 compatible serial port connector
located behind the hinged door on the right front of the power supply, through the same 6 foot
serial interface cable, IC693CBL303, or equivalent, Figure B-2).
