Chapter 1: Introduction

1.1 Product Introduction

RS-232 I/O series, a line of Universal PCI Multi-port Serial

Communication Board, is designed for both 3.3V/5V 32/64-bit PCI

Bus with Plug and Play feature. It can be installed in virtually any

available PC system and compatible with all major operating systems.

Users do not need to manually set jumpers to configure I/O addresses

and IRQ locations. Besides this board supports 5VDC or 12DV of

power from each serial port via 1/4/8/9 pin output. It’s convenient for

users connecting serial devices without addition external power supply.

This board offer independent serial ports for connecting terminals,

modems, printers, scanners, cash registers, bar code readers, keypads,

numeric displays, electrical scales, data acquisition equipment, and

other serial devices for the PC and compatible systems. This board

offers a reliable and high performance solution for serial multi-port

communications.

Chapter 2: Getting Started

2.1 Hardware Installation

1. Turn off the power to your computer.

2. Unplug the power cord and remove your computer’s cover.

3. Remove the slot bracket from an available PCI slot.

4. To install the card, carefully align the card’s bus connector with

the selected PCI slot on the motherboard. Push the board down

firml y.

5. Replace the slot bracket’s holding screw to secure the card.

6. Replace the computer cover and reconnect the power cord.

Power for the Powered RS-232 DB9 connectors are supplied from

4-pin connector located on the PCB. This connectors allows a PC

MN2000000198 Page 6

CD-ROM type power supply connector to provide the higher currents

required by the power peripherals.

In order to get efficient intake current output, there is one set of 4-pin

power connector designed on the board. The 4-pin power set draws

both +12VDC and +5VDC power output for powered RS-232 device

using.

Note: If system’s power supply can not provide the efficient power to

serial devices, it will cause your PC system unstable or unexpected

reboot.

2.2 Jumper Settings

This powered RS-232 board supports DC power output to device

feature. You can select +5V or +12VDC power output to serial device

over DB 1st, 4th, 8th and 9th pin. Please follow the jumper settings

before using each COM port.

MN2000000198 Page 7

CAUTION

1. Be sure to confirm your serial device power voltage sourcing and

pin number to prevent any further problem.

Before plugging this board into your system, please carefully

check the power output jumper setting and hardware installation

steps to prevent any damages.

3. Wrong operating damages connected serial device.

4. DO NOT cross the jumper settings over different pin define.

You can read below silkscreen print on the PCB. Each COM port has

four jumper settings for the 1/4/8/9 pin for DB9 male connector. You

can select standard RS-232 signal (system default), +5VDC, or

+12VDC power output on the assigned pin.
