Troubleshooting

Having trouble with your modem? Try these basic troubleshoot-
ing steps first!
1. Is your modem turned on? When your modem is properly connected to an
electrical outlet, a wall outlet, or a surge protector and is turned on, the
CTS and MR lights on the front panel will be illuminated.
2. Is your power supply connected properly to both your modem and an elec-
trical 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, preferably the one that
came with your modem. There are many computer cables that look similar
to an RS-232 that will not work correctly with this modem. For example, a
Null Modem cable will not work with your 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.
