MultiModem ZPX Quick Start Guide

Step 2 - Configure Jumpers

The MT5634ZPX board contains seven 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.
1. Before handling the MT5634ZPX, discharge static in your body by touching a metal
piece of the computer chassis. Carefully remove the MultiModem 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 jumper from the default position
to the position that supports your application.
3. To change the COM port assignment from the default COM4, move the berg jumpers
from their default positions to your new positions that supports your application.
