1. Introduction
Moxa’s Mini PCI Express serial boards meet the new slot standard for expansion boards and work with any
Mini PCI Express slots. The boards have multiple RS-232/422/485 serial ports to connect data acquisition
equipment and other serial devices to a PC.
Overview
Moxa’s new Mini PCI Express Multiport Serial Boards family fulfills a customized expansion need and
provides a faster response to market. It includes isolated and non-isolated RS-232/422/485 communication
cards for a variety of applications and users, such as industrial automation system manufacturers, system
integrators, and industrial PC makers.
Mini PCI Express Solution
All mini PCIe Serial Boards feature high performance 16C950 compatible UARTs. Available in 4-port and 2-
port versions, they are compatible with all popular operating systems, supports data rates of up to 921.6
kbps, and have 128-byte transmit and receive FIFOs. All mini PCIe serial cards operate in wide
temperatures, ranging from -40 to 85°C. In addition, the packaging of all mini PCIe serial cards include door
brackets, allowing the board to be installed in Moxa IPC Expansion slots.
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 transmitters and receivers to be used on the same data line. RS-485 uses half-duplex
transmission, meaning transmission and reception share the same data channels. Hence, 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 automatically. We call this
form of switching Automatic Data Direction Control (ADDC®). ADDC® is much easier to implement than the
traditional handshaking method that uses the RTS signal.
Operating System Support
The Mini PCI Express boards are compatible with all major industrial platforms, including Windows and
Linux. Moxa device drivers are provided for smoother installation, configuration, and performance.
Visit Moxa’s website at www.moxa.com to download the latest drivers and user’s manuals for all of Moxa’s
products.

2. Hardware Installation
In this chapter, we show the dimensions diagrams for all the boards in the Mini PCI Express Series and
describe the hardware installation procedure. Since the BIOS automatically assigns the PCI Express board’s
IRQ number and I/O addresses, you must plug in the board before installing the driver (driver installation is
discussed in Chapter 3).
Hardware Installation Procedure
The Mini PCI Express board must be plugged into the PC before installing the driver. The following steps
show how to install the Moxa Mini PCI express cards.
1. Find the Mini PCIe slot in your computer.
2. Insert the Mini PCIe multiport serial board and lock the screws.
3. Unscrew to remove the blank expansion plate. (We use Moxa V2406C as an example.)
For the models (CP-102N-T, CP-102N-I-T, CP-132N-T, CP-132N-I-T, CP-104N-
T) without I/O boards.
4. Unscrew the hexagonal copper pillars on the cable (DB9 Connector) and use them to connect the
provided cables with the bracket.
5. Insert the plate through the blank expansion slot and lock the screws.

6. Connect the Mini PCIe multiport serial board with the cables.
For the models (CP-104N-I-T, CP-134N-I-T, CP-114N-T) with I/O boards.
4. Unscrew the hexagonal copper pillars on the I/O board and lock the I/O board with the bracket.
5. Insert the I/O board with the bracket through the blank plate hole and lock the screws.
6. Connect the I/O board to the Mini PCIe multiport serial board with the serial cables.
