Step 2 - Configure Jumpers
The MT5634ZPX board contains seven Berg jumpers for setting the interrupt request (IRQ) number and
COM port assignment. The jumpers are located on the lower part of the PC board as shown below. The
IRQ number is set using jumpers 1, 2, and 3 and the COM port assignment is set using jumpers 4
through 7. The default IRQ number is IRQ5 and the default COM port assignment is COM4.

PC Board Jumpers
1. Before handling the MT5634ZPX, discharge static in your body by touching a metal piece of
the computer chassis. Carefully remove the MultiModemZPX from its antistatic bag, handling
it only by the mounting bracket and edges. Do not touch the gold-plated connectors along the
bottom edge.
2. To change the IRQ from the default IRQ5, move the berg jumper from the default position to
your new position that supports your application.
3. To change the COM port assignment from the default COM4, move the two berg jumpers from
their default positions to your new positions that supports your application.
Step 3 - Install the Modem into Your Computer
Installing the MultiModemZPX requires you to open your computer. Please consult your computer manual
in addition to the following instructions:
1. Turn off the computer and unplug it. Failure to do so may result in damage to both the
MultiModemZPX and the computer. Do not turn on the computer until the instructions tell you
to do so.
2. Remove the cover from the computer as instructed in the computer manual.
3. Select an empty ISA expansion slot. Remove the expansion slot cover and save the retaining
screw.
4. Place the MultiModemZPX directly above the expansion slot and gently, but firmly, push it into
the connector until the card’s retaining bracket is flush against the computer chassis.
5. Fasten the retaining bracket to the computer chassis with the screw saved in step 3.
6. Replace the cover of the computer.
