If you build you own cable, use a connector that is compatible with your serial device. 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.
Connect the 25-pin male connector on the 10 foot cable to the 25-pin female connector on the converter. Installation of these cables should be done with the programmable controller powered-down. The catalog number of this cable is IC693CB元03. A standard 6-foot cable (HHP compatible) is available to connect the RS-422/RS-485 port on the converter to the RS-485 port on the programmable controller. The catalog numbers of these cables are: IC690CBL701 (use with the IC640 industrial computer, or IBM PC-XT or compatible personal computer), IC690CBL702 (use with IBM PC-AT or compatible personal computer), and IC690CBL705 (use with the IC647 industrial computer, or IBM PS/2 or compatible personal computer). Select one of the three RS-232 compatible cables (10 feet in length) that will connect the programmer’s (or other serial device) RS-232 serial port to the RS-232 port on the converter. You do not need to connect an external source of power to the converter for a cable length of 10 feet, or less, since the necessary power connections of +5 VDC and signal ground are derived from the programmable controller’s backplane bus through the cable which connects to the IC692, IC693, or IC697 programmable controller. Specifications for building these cables are provided later. Prewired cables (see below) are available, or if cables of different lengths are required by your application, you can build your own cables. Select the proper cables for your installation. 2 GFK-0550E August 1997 Accessories RS-422/RS-485 to RS-232 Converter Installation Installation of the RS-422/RS-485 to RS-232 Converter consists of connecting two cables.
