“I want DHCP” is preselected to set up the network
using dynamic IP addressing. The Gateway is set
up at the factory to receive an IP assignment from a
DHCP Server.

1. If a DHCP Server is not available on your network,
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
change the Serial Server’s TCP/IP settings.

There are additional conguration pages that may be
accessed by selecting “Next” at the bottom of each
page, or by selecting the desired page from the
vertical list in the left-hand column.

The Vlinx Serial Server Manager defaults to options
like “Network” and “I don’t know the IP of the
device.” If the defaults meet your needs you don’t
need to set or change them.

If you have completed the conguration, click Save to
save the conguration to the serial server. Allow 15
seconds for the Serial Server to reboot.

Click “Connect.” You should see a list of all
devices on the network, including your new
device. If you do not see your new device,
please refer to the Troubleshooting tips.

You may now log out.
