STARTUP MANUAL
PCM-3641I/3642I
4/8-port RS-232 Modules
The PCM-3641I/3642I is a PCI-104-compatible
4/8-port RS-232 serial interface module. It works
with PCI-104 CPU modules or CPU cards which
accept PCI-104 expansion modules. It provides four
and eight independent serial interfaces, accessed
through the IDC 40-pin connector(s). 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
(PCM-3641I) or COM1~COM8(PCM-3642I)
port addresses.
We carefully inspected the PCM-3641I/3642I 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 max configuration for the PCI bus of PCI-104
modules is FOUR plus the host board. If you stack
more than one PCI-104 module to a host board be sure
to set the modules to different PCI numbers through

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 PCI-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-3641I/3642I
with the PCI-104 connector. Slide the module into
the connector, 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-3641I/3642I.
9. Reinstall the CPU card and replace the system unit
cover. Reconnect the cables you removed in step 2.
10. Turn the power on.
Connecting to another PCI-104 module.
1. Insert the pins of connector CN15 into the piggy-
back connector on the other PCI-104 module.
2. Screw the PCM-3641I/3642I to the brass spacer. This
completes the hardware installation.
