STARTUP MANUAL
PCM-3641P
4-port RS-232 High-Speed Module
The PCM-3641P is a PC/104+-compatible 4-port
RS-232 serial interface module. It works with PC/
104+ CPU modules or CPU cards which accept PC/
104+ expansion modules. It provides four
independent serial interfaces, accessed through an
IDC 40-pin connector. The module’s industry-
standard 16C550 asynchronous communication chip
is fully programmable. The module requires no
special commands or control codes if you use the
standard COM1 ~ COM4 port addresses.
We carefully inspected the PCM-3641P both
mechanically and electrically before we shipped it.
It should be free of marks and scratches and in per-
fect electrical order on receipt.
Handle the board only by its edges. The static
charge on your body may damage its integrated cir-
cuits. Keep the card in its anti-static package when-
ever it is not installed. You can use this package to
return the card if it should need repair.

Card Configuration
The maximum configuration for the PCI bus of PC/
104+ modules is FOUR plus the host board. If standard
PC/104 modules are used in the stack, they must be the
top module(s) because they will normally not include
the PCI bus.
If you stack more than one PCI-104+ or PC/104+ mod-
ule to a host board. You have to set the modules to dif-
ferent PCI numbers through SW2

Hardware Installation
Installing the module on a CPU card
1. Turn the PC’s power off. Turn the power off to any
peripheral devices such as printers and monitors.
2. Disconnect the power cord and any other cables from
the back of the computer.
3. Remove the system unit cover
4. Remove the CPU card from the chassis (if necessary)
to gain access to the card’s PC/104+ connector.
5. Screw the brass spacer (included with the module)
into the threaded hole on the CPU card. Do not
tighten too much, or the threads may be damaged.
6. Carefully align the pins of the PCM-3641P with the
PC/104+ connector. Slide the module into the con-
nector, do not push too hard.
7. Secure the module to the CPU card to the threaded
hole in the CPU card using the included screw.
8. Attach any accessories to the PCM-3641P.
9. Reinstall the CPU card and replace the system unit
cover. Reconnect the cables you removed in step 2.
Turn the power on.
Connecting to another PC/104+ module.
1. Insert the pins of connector CN15 into the piggy-
back connector on the other PC/104+ module.
2. Screw the PCM-3641P to the brass spacer. This com-
pletes the hardware installation.
