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 2port 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.
ADDCTM (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.

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-112N-T, CP-132N-T, CP-132N-IT, 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.

Overview

In this section, it shows the port parameters such as COM Number, TX and RX FIFO level, and Termination Resistor. The following are the description of this parameters.
· Port Number and COM No. You will need to set up all the ports of the board with the desired “COM number”, which should not conflict with other COM numbers in use.
· RX and TX FIFO Rx FIFO Level Low – Disables FIFO, resulting in decreased latency, and low throughput. High – Results in high throughput, but with increased latency. (Default) Tx FIFO Level Low – Disables FIFO (recommended when the attached serial device has a small buffer, or slow transmission speed). High – Results in high throughput. (Default)
· Interface · This column shows the interface of serial ports. You can change the interface by clicking the Port Setting
button and making the changes in “Port Setting” dialog box. For the RS-232/422/485 serial boards, the interface default setting is RS-232. For the RS-422/485 serial boards, the interface default setting is RS-485 2W · Termination Resistor You may need to enable the termination resistor in the long communication distance. Enable (120 ohm) Disable (Default)
3. Port Setting:
Click this button, which will open the port setting window for you to configure the serial ports.

Bias Resistor Setting
The termination resistor (120, Enable, or Disable) and pull high/low resistor will be set by the DIP switch on the main board (CP-132N-T, CP-132-I-T). For the models CP-114N-T and CP-134N-I-T, you can find the DIP switch on the I/O boards. The default setting of the resistors is disable termination resistor and use 150 kohm. If you connect serial cables with a long range, we recommend you enable the 120-ohm termination resistor and set the pull high/low at 1 kohm. Otherwise, please keep it in the default setting so that the serial device continues to work as normal.

UART Register Structure for MUE250, MUE450, and MUE850 Chips
There are 512 bytes for each UART register and 0x200 offset between each port. However, there is one exception: for the models that are 4-port boards, such as CP-104EL-A, CP-114EL, CP-114EL-I, and CP134EL-A, the offset of the fourth UART register is 0xE00.

Registers for 8 ports

Registers for 4 ports

NOTE
For a detailed description of the UART register, please see the UART Datasheet section.

UART register address = I/O base address + (port-1) * 0x200
For example, if the base address is 0x200:
The first port’s UART register’s I/O address is 0x200 + (1-1) * 0x200 = 0x200 The first register’s I/O address is 0x200, The second register’s I/O address is 0x201, …..
The second port’s UART register’s I/O address is 0x200 + (2-1) * 0x200 = 0x400 The first register’s I/O register is 0x400, The second register’s I/O register is 0x401, …..

Troubleshooting

In this chapter, we discuss the common PCI Express Series problems and possible solutions. If you still have problems after reading this chapter, contact your dealer or Moxa for help, or use the Problem Report Form at the end of this manual to report problems to your dealer.
1. The Moxa PCI Express board cannot be detected by the Moxa driver while installing the driver. Hardware causes and solutions: a. Express slot. It is possible that a slot has malfunctioned. In this case, try other slots until you find one that works. b. The motherboard does not have an available IRQ for the PCI Express board. In this case, enter the BIOS and make sure there is an available IRQ under PCI/PnP settings.

2. The Moxa PCI Express board and driver are activated but cannot transfer (transmit/receive) data. Hardware Causes and Solutions: a. Make sure the cable wiring is connected correctly. Refer to Chapter 6, “Pin Assignments”, for correct cable connections. b. The cable or the board could be defective. Try other ports, cables, or boards to verify this, or use the PComm Diagnostic utility to test the Moxa board and port conditions. If the Diagnostic program reports an error, replace the faulty components. Software Causes and Solutions: a. PCI Express Series boards will check the line status (CTS) before transmitting data if the RTS/CTS flow control feature is set to Enable in the configuration or application program. Refer to the “Connection Cables and Cable Wiring” chapter for proper wiring diagrams; then, check the line status of the suspected port, using the diagnostics LED indicators on the mini tester. b. The board control application may not be written correctly according to the corresponding API of the operating system. To check this problem, run another application that you know is correct, or use the utilities provided by Moxa (such as PComm Terminal emulatorl that runs under the Windows platform).
