The RS232 and RS485 Modbus Parameters tabs
show the configuration parameters for the RS232

4.4.1 Mesh
Enable IP
Gateway Mode
Enabling this option will allow communicating modules access to an
external Ethernet Network if connected (IP address range
configured under Network Settings). Care should be taken when
enabling this option as it can increase overall network traffic.
Default is off and should remain off unless there is an Ethernet
network connected and other devices on the radio network need to
communicate through this module to the external Ethernet network.
All traffic for the external network must be routed through this IP
address.
