Type IP Address

Figure 38.

Note: Your Modbus Gateway comes from the factory pre-configured to receive an IP address
assignment from a DHCP server. If a DHCP Server is not available on your network, it will
default to 169.254.102.39.

The web interface Login page appears.

Modbus Gateway Login Screen

The screens for configuring your gateway using a web browser are the same as
those used to configure using the Vlinx Modbus Manager software.
