and check the interface

TCP/IP on page 2-52.

Properties you have set on that connection. Double-check to ensure that you
have set Windows parameters as described in
Appendix: Setting Up Serial
Communications on page 2- 67.

If your Direct Connect does not work:
A) Check to make sure that the cables are connected properly.
B) Check that you are using a null modem cable.
C) Ensure that the null modem cable is connected to the 8685’s serial connector.

If you cannot connect to your computer through a crossover Ethernet cable:
You must set your Windows networking to provide a static IP address for
your computer because your Optimod does not contain a DHCP server.
You Cannot Access the Internet After
Making a Direct or Modem Connection to the 8685:
If you are connected to the 8685 via modem or direct connect, you cannot access
any other TCP/IP connection . The PPP connection becomes the default protocol
and the default gateway defaults to the 8685 unit’s IP address. This means that
all existing network connections point to the 8685 unit. To correct this:
A) In Start > Settings > Network and Dialup Connections, open the direct or mo-
dem connection you are using to connect to 8685.
B) Select “Properties.”
C) Click the tab that reads “Networking.”
D) Highlight “Internet protocol (TCP/IP).”
E) Select “Properties.”
