MultiModemDID User Guide
(Optional) Connect the Modem to the Phone
For voice-only calls, plug a phone into the modem’s PHONE jack.
Connect the Modem to the AC Power Outlet
Make sure the power is switch is OFF. Plug the DC power transformer into a power outlet or power
strip. Plug the other end into the PWR jack on the modem. The DC power transformer is included
with your modem.
CAUTION: Use only the DC power transformer supplied with the modem. Use of any other
transformer voids the warranty and can damage the modem.
Connect the Modem to the DID Line
Plug one end of the phone cable into the modem’s DID jack and the other end into an analog DID
trunk line jack. The DID Line cable is included with your modem.
CAUTION: The DID Line cable has a 4-pos RJ11 on one side and a 6-pos on the other. Never plug
the DID connector into a standard POTS Line. This may damage the modem or the central office
equipment. Use only an analog DID Line.
Power-on Test
Test the modem by turning it on (an on-off switch is located on the side panel). When you apply
power, the modem performs a diagnostic self-test. The 56 indicator lights, and if a terminal program
is running, the TR indicator also lights. If this does not happen, check that the power switch is on,
the power supply is solidly connected, and the AC outlet is live. If these measures do not work, see
the
Troubleshooting
chapter.
Step 3: Install the Modem Driver
1. Make sure your modem is connected properly, and then turn on your computer. Windows should
detect your new modem and open the Install New Modem wizard.
Note: If Windows cannot find a modem, your modem may be turned off, it may be plugged into the
wrong connector on your computer, or the serial cable may be faulty. See “None of the LEDs Light
When the Modem Is Turned On” and “The Modem Does Not Respond to Commands” in the
“Troubleshooting” chapter in the complete User Guide.
2. Insert the MT5634ZBA-DID CD into your CD-ROM drive, and then click OK.
3. Windows installs the modem driver.
4. Click Finish to exit
Removing Your Old Modem from Windows
When your new modem replaces another modem, the old modem installation remains in Windows after
you install the new modem, and the old modem is still selected in HyperTerminal and other Windows
applications. Although you can change the application connection descriptions one at a time, it is easier
to force Windows applications to use the new modem by removing the old modem from Windows.
