Functions
The RS-422/RS-485 to RS-232 Converter provides an RS-232 serial interface for the Series 90-70
and Series 90-30 PLCs, which have a built-in RS-422/RS-485 interface. Specifically, it provides a
serial connection between a Series 90-30 or Series 90-70 PLC serial port and the serial port on the
programming computer without the need for a Work Station Interface to be installed in the
computer. The programming computer can be a Workmaster II computer, or IBM PS/2 or
compatible computer.
