1 Chapter 1Introduction Welcome to the MOXA CP-132UL Series of industrial 2-port RS-422/485 serial boards for the PCI bus. Moxa’s Universal PCI CP-132UL series meets the new slot standard for expansion boards, and works with both 3.3V and 5V PCI slots. The CP-132UL series offers 2 independent RS-422/485 serial ports for connecting data acquisition equipment and many other serial devices to a PC and compatible systems.
Overview Industio—The Industrial Multiport Async Solution Moxa Industio products are smart, multiport serial I/O solutions for industrial applications. The CP-132U Series boards, including CP-132UL V2, and CP-132UL-I V2 (the previous version is CP-132U-I V1), are designed for a 32-bit PCI bus with the Plug and Play and Universal PCI feature. They offer 2 independent RS-422/RS-485 serial ports for connecting data acquisition equipment and many other serial devices to the PC and its compatible systems.
Introduction PCI Solution The board complies with PCI Spec. 2.1 and does not require either switches or jumpers. The hardware configuration for the IRQ and I/O address is automatically assigned by the PCI BIOS. This means that the board MUST be plugged into the computer first before installing the driver software. For more PCI information, refer to the Technical Reference Appendix. Universal PCI The 32/64-bit PCI local bus specification specifies both 3.3V and 5V connector types for the PCI hardware.
Features The CP-132UL Series includes the following products: CP-132UL V2 CP-132UL-I V2 2 RS-422/485 ports, Universal PCI interface with embedded Surge Protection (16 KV ESD) 2 RS-422/485 ports, Universal PCI interface with embedded Surge Protection and Isolation Protection (16 KV ESD, 2 KV Isolation) CP-132UL Series boards have the following outstanding features: ! ! ! ! ! ! ! ! ! ! ! !

CP-132UL V2 (120 x 64.5 mm) CP-132UL V1 (120 x 64.
Hardware Installation CP-132UL Series boards have four onboard DIP Switches, referred to below as S1-1, S1-2, S2-1, and S2-2, that allow the user to choose one of three serial interfaces—RS-422, RS-485 (2-wire), RS-485 (4-wire)—for each of the two ports. Note that S2-1 and S2-2 select between RS-422 and RS-485, and S1-1 and S1-2 select between 2-wire and 4-wire RS-485 (S1 is only active when S2 is set to ON).
Installing the CP-132UL Series Board Step 1: Power off the PC. Warning! To avoid damaging your system and board, make sure your computer is turned off before installing any board. Step 2: Remove the PC’s cover. Step 3: Remove the slot cover bracket if there is one. Step 4: Plug the CP-132U Series control board firmly into a free 32-bit PCI slot or 64-bit PCI slot. Step 5: Fasten the holding screw to fix the control board in place. Step 6: Replace the system cover. Step 7: Power on the PC.

4 Chapter 4Serial Programming Tools Moxa supports an easy to use yet powerful serial programming library and communication troubleshooting utilities under Windows NT, Windows 95/98, and Windows 2000/XP/2003.You can save a lot of development time by using MOXA’s Serial Programming Tools. The following sections give details about the installation, the library, and the utilities for various platforms.
PComm Programming Library The serial communication library helps you develop programs for serial communications for any COM port complying with the Microsoft Win32 API. It facilitates the implementation of multi-process and multi-thread serial communication programs, and consequently greatly reduces developing time. For a complete library function description and sample programs for Visual C++, Visual Basic, and Delphi, check the help file and the sample programs in the PComm directory.
Software Installation Monitor (for MOXA boards under Windows NT/2000/XP/2003) A useful port status monitoring program allows you to monitor data transmission of selected MOXA COM ports. It monitors data transmission/receiving throughput, and communication line status, with data updated and displayed on the screen at regular time intervals. Click on a specific port to see a graph of the current communication parameters and status of that port.
Terminal Emulator Terminal Emulator can be used to connect to various ports to see if data transmission is functioning correctly. Terminal Emulator features multi-windows, and supports VT100 and ANSI terminal types. You can transfer data interactively, send patterns periodically, and transfer files using ASCII, XMODEM, YMODEM, ZMODEM, and KERMIT protocols. To run Terminal Emulator, click on [Start]#[Program]#[Pcomm Lite]#[Terminal Emulator].
Software Installation RS-485 Programming If you intend to use your CP-132UL Series board for RS-485 applications, you can refer to the RS-485 programming guide below, and also see the chapter, “Connection Cables and Cable Wiring,” for more details about RS-485 operation. The CP-132UL Series supports only 2-wire half-duplex RS-485 communication. In this case, the data+/- pins are used for both data transmitting and receiving, depending on the mode selected.
and receiving), since it is automatically managed with the board’s built-in intelligent hardware mechanism. This means that RS-485 programming using ADDC™ mode is just as simple and straightforward as RS-232 or RS-422 programming. How to transmit and receive data for Windows 95/98NT/2000/XP/2003 In order to acquire precise timing control for RS-485 2-wire transmission, we recommend that you configure your CP-132UL Series ports as described below. There are 2 solutions to control RS-485 2-wire transmission.

Connection Cables and Cables Wiring Impedance Matching and Termination Resistors When using RS-422/485 serial communications, an electrical signal that travels through two different resistance junctions in a transmission line will sometimes give rise to signal reflection due to the impedance mismatch. Signal reflection causes signal distortion, which in turn contributes to communication errors.
6 Chapter 6Troubleshooting Common CP-132UL Series problems and possible solutions are listed below. 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. General Troubleshooting 1. The MOXA PCI board cannot be detected by the MOXA driver while installing the driver. Hardware causes and solutions: a. The board is not installed in the computer. Please install it. b.
2. The MOXA 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 the “Connection Cable and Cable Wiring” chapter for correct cable connections. b. The cable or the board are probably defective. Try other ports, cables, or boards to verify this, or use the PComm Diagnostic utility to test the MOXA board’s and port conditions. If Diagnostic reports an error, replace the faulty components.
Technical Reference Windows NT This section is specifically for troubleshooting under Windows NT. For general problems and solutions, see the previous section, “General Troubleshooting.” 1. After the system reboots, the error message “Another driver in the system, which did not report its resources, has already claimed the interrupt used by xxx.” appears in the Event Log. This indicates the MOXA board was found, but the IRQ is conflicting with another adapter.
Windows 95/98 This section is specifically for troubleshooting under Windows 95/98. For general problems and solutions, see the previous section, “General Troubleshooting.” 1. 2. The system fails to find the CP-132U Series board! ! The board(s) is(are) not plugged properly. ! The slot the boards are plugged into is defective. Try another slot until you find one that works. ! The board might be defective.

The IRQ and I/O address hardware configuration is automatically assigned by the PCI BIOS. This means that you must first plug in the board before installing the driver software.
Technical Reference Return Procedure For product repair, exchange, or refund, the customer must: $ Provide evidence of original purchase. $ Obtain a Product Return Agreement (PRA) from the sales representative or dealer. $ Fill out the Problem Report Form (PRF). Include as much detail as possible for a shorter product repair time. $ Carefully pack the product in an anti-static package, and send it, pre-paid, to the dealer.
