Configuration by the Telnet Console‎ ‎

Modbus Ethernet Gateways (G01 - G03 & G14 - G16)
The device can be also configured via the Telnet Console. Firstly, make sure that converter is connected to the power supply and to the LAN using a patch cord. Knowledge of the device’s IP address (default is 192.168.100.100) and Telnet port number (default is 23) is necessary to establish a connection.
Use command below in a terminal window to connect to the device:
telnet <ip_address> <port_number>
If the connection is successful there will be login prompt visible. Login using user's personal credentials or the default login details (login: admin, password: admin123). If login is successful, it will be possible to start typing configuration commands.
The configuration is available only if devices are connected to the same Local Area Network as the computer used for it.

[LP]: [SLAVES NUMBERS] [IP/HOSTNAME] [PORT] [TIMEOUT]
modbus_routing add SLAVE_ADDR HOSTNAME PORT TIMEOUT
SLAVE_ADDR with HOSTNAME PORT is used by uarts working in Modbus router mode. TIMEOUT (in ms) is used to close the connection if a slave is not responding. The maximum records is 8. One record for one address/ip.
Example:
modbus_routing add 18 192.168.0.10 502 2000
