Setup guide

A serial controller is any device that can send and receive ASCII code
via RS232 or RS422. You can connect a serial controller to either of the
two serial connectors on an enclosure’s CPU board. Connect serial
controllers with either standard RS232or RS422 connections (refer to the
graphics below for RS232 and RS422 cable connector pin mappings).
The pin diagram above allows for hardware flow control. If this type of
control is not needed, connect pin #7 to pin #8 on the PC’s connector.
When controlling the system with a PC, use serial communication
software and make sure the BAUD rate is set correctly for the system.
Available BAUD rates for Modula systems are 9600, 19200, 38400 and
57600; the default is 9600.
