Description of Miniconverter
The Miniconverter Kit (IC690ACC901) 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 Converter Plug assembly. 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 Converter plug (supplied with kit) is required to convert 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.
