IC690ACC901 Miniconverter Kit

The Miniconverter Kit consists of an RS-422 (SNP) to RS-232 Miniconverter, a 6 foot (2 meter)
serial extension cable, and a 9-pin to 25-pin adapter. The 15-pin SNP port connector on the
Miniconverter plugs directly into the serial port connector on the Series 90-30 power supply,
Series 90-70 CPU, or Series 90-20 CPU. The 9-pin RS-232 port connector on the Miniconverter
connects to an RS-232 compatible device.
When used with an IBM PC-AT or compatible computer, one end of the extension cable plugs into
the Miniconverter's 9-pin serial port connector, the other end plugs into the 9-pin serial port of the
computer. The adapter (supplied with kit) is required to adapt the 9-pin serial port connector on
the Miniconverter to the 25-pin serial port connector on the GE Workmaster II computer,
or an IBM PC-XT or PS/2 Personal Computer. The GE Workmaster computer requires an
additional adapter (not supplied with kit - please contact your local GE PLC distributor) for
use with the Miniconverter.
The Miniconverter is shown in the following figure. For more information on the Miniconverter,
refer to Appendix D.
