The serial port interface allows the user to configure the module and to program the
ASCII messages into the module. This is only activated when the module enters into
its programming mode via the front panel push button.
NOTE: The serial port is capable of communicating with either a dumb terminal or a
PC using terminal emulation software (i.e., PROCOMM).
Serial Port Setup
When programming mode is entered, one of the RS-232 serial ports is set to a
standard terminal communication’s configuration to communicate with the user on
the programming terminal via a Modbus. This communication configuration consists
of the following.
The serial port configuration has been set this way so that the configuration of the
port is a known configuration and may or may not be the same configuration that is
used when the module is running.
Front Panel Reset Push Button
A recessed push button on the front of the module is used to reset the module.
