If none of the commands above produce results then check the following:
1. Check the Phone Line
•
•
If direct connecting and phone line is not available make sure there is no dial tone
on the panel and use the WATELCO Cable’s Black and Yellow wires to simulate
a dial tone.
If direct connecting and phone line is available make sure the Black and Yellow is
NOT hooked up to the panel. Keep the phone line with adequate dial tone on the
incoming ring and tip terminals on your control panel.
2. Check Modem Power
•
Specs: 9VAC 1Amp (1000mA)
3. Change Comports
•
•
If multiple comports are available try a different port, if not try another machine
If using a Keyspan USB to serial Adapter try emulating a different comport.
4. Try Another Modem
