3.9.4 RS232
The RS232 port on the controller supports the Modbus RTU protocol.
The Gencomm register table for the controller is available upon request from the DSE Technical
Support Department.
RS232 is for short distance communication (max 15m) and is typically used to connect the controller
to a telephone or GSM modem for more remote communications.
Many PCs are not fitted with an internal RS232 serial port. DSE DO NOT recommend the use of USB
to RS232 convertors but can recommend PC add-ons to provide the computer with an RS232 port.
