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 proper settings.
5. Is your phone cord properly connected? The phone cord should be plugged into the
phone jack. Use the phone cord included in your modem's box if possible.
PROBLEM: My computer isn't recognizing my modem.
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:
Make sure you are using the proper cable. This modem requires an RS-232 serial 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 correctly with this
modem.
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.
