Clock Communication Troubleshooting
2. Many modems will not communicate with the clock if they do not
have the current driver. Check your modem manufacturer’s web
site for the most current driver. This fixes many modem issues.
3. The clock needs its own line when communicating. This does not
mean that the clock cannot share a phone line with another device
(such as a fax machine), but when it is communicating it needs to
be on the line alone. Make sure that any shared device is unplugged
from the wall when you call the clock. A fax machine, credit card
machine, or other modem device will always pick up if hooked to
the same phone jack as the clock.
Note: Many companies sell AB switches for telephone lines. Infini-
source also sells a com device called “The Stick.” Using either of
these options is preferable to constantly changing the cables since
with repeated insertion and removal, the wires inside the connector
will eventually wear out and fail.
4. Check the number of the line that the clock is connected to. In the
software, ensure that the number is entered exactly as you would
dial it over a telephone. Does it need a 9 first? Does it require an
area code? Does it require a 1?
5. Pick up a phone and call the clock. When the clock receives the
incoming call the word “CALL” should appear on the display
where the time is normally shown.
6. Disconnect the clock from the phone jack and plug in a normal
phone. You should be able to pick up the phone and hear a dial tone.
If there is no dial tone, the modem cannot work with the line. The
phone line must be able to send and receive “analog” communica-
tions (“digital” will not work).
7. With the phone connected to the line, try connecting to the time
clock. The phone should ring, and when you pick it up you should
hear tones from the computer modem trying to connect. If the
phone doesn’t ring, then the number you are calling is not the num-
ber for that line.
