using dynamic IP addressing. The Gateway is set
up at the factory to receive an IP assignment from a
DHCP Server.

it will default to 169.254.102.39.

2. 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:

169.25 4.102.100 .

If you are not able to use these settings in your
installation, refer to the User’s Manual for directions to
