Basic Troubleshooting
Steps 1. Is your modem turned on? When your modem is properly connected to power and is turned on, the CS light on the front panel will be on.
2. Is your power supply connected properly to both your modem and an
electrical outlet? If it is, check the outlet with another electric device (like
a lamp) to be sure that you are getting power. Also, use the power supply
that came with your modem; other similar-looking power supplies may
be of different voltages and could damage your modem.
3. Are you using the proper cable to connect your modem to your
computer? Make sure you are using an RS-232 modem cable. Check the
packaging of the cable you bought. There are many computer cables that
look similar to an RS-232, such as a Null Modem cable, that will not work

12 CHAPTER4: TROUBLESHOOTINGAND HELPRESOURCES
with this modem. Depending on whether you have a 9-pin or 25-pin
serial port on your computer, you will need either a DB9/DB25 or a
DB25/DB25 serial cable. See the diagrams below.
You need a
DB9F/DB25M
RS-232 serial cable.
You need a
DB25F/DB25M
RS-232 serial cable.
4. If there are DIP switches on the back of your modem, are they set
correctly? DIP switches 3, 5, and 8 should be in the down position. See
the diagram below for the correct settings.
5. Is your phone cord properly connected? The phone cord should be
plugged into the jack labelled on the modem and into the wall
phone jack. Use the phone cord included in your modem's box if possible
My computer isn't

Possible solution:
You may be using a COM port that is either already in use or not
configured correctly. To work properly, this modem needs to be plugged
into an enabled serial port which is assigned to a free COM port. Typically,
most computers have two serial ports assigned to COM 1 & 2
respectively.
Windows 2000 Make sure your COM port is not already in use by
another modem. Click Windows Start, Settings, and Control Panel,
and then double-click Phone and Modem Options. Click the Modems

ExternalSerialModems 13
tab. Look for another modem already in the machine. If there is another
modem listed, check which COM port it is using. If a previous modem is
already using the available COM port, you can either use another COM
port or uninstall the previously installed modem. See your previous
modem's manual for uninstallation instructions.
Next make sure that your COM Ports are configured correctly. Right-click
the My Computer icon on your desktop. Click Properties. Click the
Hardware tab. In the “Device Manager” section, click theDevice
Manager button. Look underPorts (COM & LPT). If the COM Ports have
yellow exclamation points or red Xs over them, your COM ports may be
configured incorrectly. If this is the case, you may need to contact your
computer manufacturer.
It is also possible that you may be plugging an external modem's cable
into a disabled serial port. Refer to your computer's manual for
information about enabling COM ports. This usually involves altering the
BIOS settings and possibly the operating system. You may need to call
your computer's manufacturer to change your BIOS settings if they are
incorrect.
Windows 95/98 Make sure your COM port is not already in use by
another modem. Click Windows Start, Settings, and Control Panel,
and then double-click Modems. Look for another modem already in the
machine. If there is another modem installed, click the Diagnosticstab
to find out which COM port it is using. If a previous modem is already
using the available COM port, you can either use another COM port or
uninstall the previously installed modem. See your previous modem's
manual for uninstallation instructions.
Next, make sure that your COM Ports are configured correctly. Right-click
the My Computer icon on your desktop. Click Properties. Click the
Device Manager tab. Look under Ports (COM & LPT). If the COM Ports
have yellow explanation points or red Xs over them, your COM ports may
be configured incorrectly. If this is the case, you may need to contact your
computer manufacturer.
It is also possible that you may be plugging an external modem's cable
into a disabled serial port. Refer to your computer's manual for
information about enabling COM ports. This usually involves altering the
BIOS settings and possibly the operating system. You may need to call
your computer's manufacturer to change your BIOS settings if they are
incorrect.

14 CHAPTER4: TROUBLESHOOTINGAND HELPRESOURCES
Windows NT Click Windows Start, Settings, and then Control
Panel. Double-click Ports. Make sure the port you are plugging the
modem into appears in the list. If it does not, the port needs to be added,
and possibly enabled in the BIOS. Consult your Windows NT manual for
information about adding ports. After you add or enable the port, follow
the instructions on the front of the Installation Guide that came with your
modem to install your modem.
My software isn't
recognizing my
modem.
Possible solution:
Your communications software may not function properly if you have
more than one version of the software installed, you are using an older
version, or you have more than one communications software installed
on your system. We highly recommend using the communications
software provided with your modem on the Installation CD-ROM.
Possible solution:
Make sure the modem is plugged in and turned on. If it is, check the
outlet with another electric device (like a lamp) to be sure that you are
getting power. Also, you must use the power supply that came with your
modem; other similar-looking power supplies may be of different
voltages and could damage your modem. When your modem is properly
connected to power and is turned on, the CS light on the front panel will
be on.
Possible solution:
Your software's port settings may be incorrect. Make sure the software's
port settings match those for your modem. This information is on the
Installation Guide that came with your modem. There should be a place
in the Setup section of your software for this.
Possible solution:
Windows 2000 You may not have the correct modem type selected in
your software or in Windows. Click on Windows Start, Settings, and
Control Panel. When Control Panel opens, click Phone and Modem
Options. Click the Modems tab. Here you will see a list of installed
modems. You can also add, remove, or view the properties of modems
from this window. The U.S. Robotics modem you have installed should be
present in the list of installed modems. If none of the modem descriptions
in the list matches your U.S. Robotics modem or no modems are listed,
