 Passcode Format: The passcode is case-sensitive. When entering it into Win-
dows’ Dial-up Connection dialog box, it must be typed exactly as it was origi-

hold down the S

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 9400. Navigate to S
ETUP >
NETWORK & REMOTE > PC CONNEC 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- 59.
 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 9400’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 9400, and
the
passcode has also 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 9400 is set to A
UTO ANSWER.
F) Make sure that the only “Allowed Network Protocol” is TCP/IP. “NetBUI” and
“IPX / SPX Compatible” must not be checked.
You Cannot Access the Internet After
Making a Direct or Modem Connection to the 9400:
If you are connected to the 9400 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 9400 unit’s IP address. This means that
all existing network connections point to the 9400 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 9400.
