PCM-3641 4-port RS-232 High-Speed Module

Introduction

The PCM-3641 is a PC/104-compatible 4-port High-Speed

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 male DB-9 connectors.

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.

Features

•Four independent RS-232 serial ports

•Transmission speeds up to 460 Kbps

•Independent/Shared IRQ settings for each of 4 serial

ports

•Wide IRQ selection: 3, 4, 5, 6, 7, 9, 10, 11, 12, 15

•Supports Standard DOS COM1, COM2, COM3, and

COM4

•Supports DOS/Windows 3.1 (PC-ComLib), Windows 95/

98/NT

•LED indicators: TX, RX

•Compatible with standard PC ports: COM1, COM2,

COM3, COM4

Initial inspection

We carefully inspected the PCM-3641 both

mechanically and electrically before we shipped it.

It should be free of marks and scratches and in

perfect electrical order on receipt.

Handle the board only by its edges. The static

charge on your body may damage its integrated

circuits. Keep the card in its anti-static package

whenever it is not installed. You can use this

package to return the card if it should need repair.

Card Conguration

Each port on the PCM-3641 card has jumpers and

2 DIP switches which require configuring prior to

use. The DIP switches set the port to the

appropriate I/O address and different modes. The

jumpers set the port’s IRQ.
