PCI Express Boards Introduction

1-2

Overview

Moxa’s new PCI Express Multiport Serial Boards are designed for POS and ATM applications and for use by
industrial automation system manufacturers and system integrators. The boards are compatible with all
popular operating systems, and each of them supports data rates of up to 921.6 kbps and provides full modem
control signals, ensuring compatibility with a wide range of serial peripherals. In addition, all models work with
PCI Express x1, allowing the boards to be installed in any available PCI Express slot (including x1, x2, x4, x8,
x16, x32).

PCI Express Solution

The boards comply with PCI Express Spec. 1.1. The ports’ transmission parameters are configured after the
boards are installed. The PCI BIOS automatically assigns the IR Q and I/O addresses. For this reason, you must
plug the boards into the computer before installing the drivers. For m ore PCI Express information, re fer to the
“Technical Reference” appendix.

ESD Protection

The PCI Express boards come with15 kV ESD protection built in to prevent damage to the boards from lightning
or high potential voltage. The surge protection feature makes the PCI Express boards suitable for industrial,
factory-type applications, and for use with applications that are subject to severe weather conditions.

ADDC™ (Automatic Data Direction Control) for RS-485

RS-485 uses differential data transmission over two wires to transmit data from one station to another, and
allows multiple trans mitters and receivers to be used on the same data line. RS-485 uses half-duplex
transmission, which means that transmission and receptio n sha re the same data channels. For this reason,
only one transmitter can be active at any given time.

Moxa’s serial boards have a built-in circuitry to switch transmitters on and off autom atically. We call this form
of switching ADDC® (automatic data direction control). ADDC® is much easier to implement than the
traditional “handshaking” method that uses the RTS signal .

Operating System Support

The PCI Express boards are compatible with all major industrial platforms, including Windows
2000/XP/2003/Vista/2008, Windows 7/8/2012, Windows CE, DOS, Linux, and SCO. Moxa device drivers are
provided for smoother installation, configuration, and performance.
