Troubleshooting Connections

If you get an error message such as “the specified port is not connected” or
“There is no answer”…
You may have the wrong interface type set on your 8382. Navigate to
S
ETUP
/
N
ETWORK
& R
EMOTE
/ PC C
ONNEC
and check the interface setting.
If you are connecting via Direct Serial Connection or modem, review the Proper-
ties you have set on that connection. Double-check to ensure that you have set
Windows parameters as described in
Appendix: Setting Up Serial Communica-
tions on page 2- 43.

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 8382’s serial connector.

If your Modem Connect does not work:
A) Ensure that the modem cables and phone lines are connected properly.
B) Check that you have entered the correct phone number for connection.
C) Check that you have entered the passcode correctly on the 8382 and the pass-
code has been entered correctly on your PC.
D) Ensure that you enabled the correct PC modem port settings.
E) Ensure that the external modem attached to your 8382 is set to
A
UTO
A
NSWER
.
F) Make sure that the only “Allowed Network Protocol” is TCP/IP. “NetBUI” and
“IPX / SPX Compatible” must
not be checked.

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 8382:
If you are connected to the 8382 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 8382 unit’s IP address. This means that
all existing network connections point to the 8382 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 8382.
B) Select “Properties.”
C) Click the tab that reads “Networking.”
