The buttons and fields in this window are:
– Link Speed and Duplex determines the speed of the communication channel. Leave the
setting at AUTO if not sure about the link speed. If manual option is selected, then the
connected device must be set to the same speed.
– Ethernet IP Configuration selects the method your network uses to obtain IP addresses.
If using static IP addresses, enter the IP address assigned to the gateway. Each device on
the network must have a different IP address.
If a DHCP server is on the network and will assign IP addresses to the AWIN GW100, click Use
DHCP to get an IP address radio button.
If the IP address is changed from the factory default, you will need to know this
to log back into the gateway for future configuration changes.
Enter a “LAN Default Gateway,” if desired.

map they wish to use. The map must be uploaded using the Browse option followed by
Submit button. For details on the Modbus file structure refer to the section Modbus Im-
port File Structure .
