I want DHCP
is preselected to set up the network using
dynamic IP addressing. The Modbus Gateway is set up at
the factory to receive an IP assignment from a DHCP
Server. If a DHCP Server is not available on your network, it
will default to
169.254.102.39
.
If a DHCP server is not available and the default address
does not work on your PC, change your PC network
settings to IP Address: 169.254.102.1, Subnet Mask:
255.255.0.0, Default Gateway: 169.254.102.100. If you are
not able to use these settings in your installation, refer to
the user’s manual for directions to change the Modbus
Gateway’s TCP/IP settings.
