8 HOWTO configure the serial MBUS interface
After you have successfully changed the IP parameters via Web page, you can configure the serial MBUS
line parameters with this steps.
There are two ways to do so:
1. Use the MODBUS/RTU or MODBUS/TCP protocol to setup the serial MBUS parameters
2. Use ASCII commands on the socket to configure the serial MBUS parameters
8.1
ASCII commands for configuration
The following table show the ASCII commands for setup of the serial MBUS line.
Please note, that there must be at least 2s pause on the serial line to activate an ASCII command.
Send this ASCII string over the socket to the gateway and wait for the answer. Socket must be in transparent
mode.
