STARTUP MANUAL

PCM-3612I

4-port RS-232/422/485 PCI-104 Module

The PCM-3612I is a PCI-104-compatible 4-port

RS-232/422/485 serial interface module. It works

with PCI-104 CPU modules or CPU cards which

accept PCI-104 expansion modules. It provides four

independent serial interfaces,accessed through the

IDE 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-3612I) port address

We carefully inspected the PCM-3612I 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 SW1.

Hardware Installation

Installing the Module on a CPU Card:

1. Turn the PC 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-3612I with the

PCI-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-3612I.

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 CN6 into the piggy-

back connector on the other PCI-104 module.

2. Screw the PCM-3612I to the brass spacer. This com-

pletes the hardware installation
