You can reconfigure the network settings like default gateway and ip address of an B&R X20 Coppler directly via telnet.

Configuring an IP address

The required function code is fc6 followed by the address position and new value, for example: fc6 0x1005 123 sets the 123 in 192.168.123.77

Configuring a Subnet Netmask

Subnet configuration is similar to the setting of the ip address, use function code fc6 for each portion of the subnet mask, see below.
