Serial Programming Tools

Moxa supports a class of easy to use, yet powerful serial programming libraries and communication troubleshooting utilities under Windows NT/2000/XP/2003 and Windows 95/98.

Use these MOXA Serial Programming Tools to decrease your software development time.

In the following sections, we describe the installation of the library, and the utilities supported for various programming platforms.

PComm, a professional serial comm tool for PCs, is a software package that runs under Windows

NT/2000/XP/2003 and Windows 95/98. PComm provides:

!

!

!

A powerful serial communication library for easy programming in the most popular programming languages. The serial communication library is useful for developing applications for data communications, remote access, data acquisition, and industrial control under Windows

NT/2000/XP/2003 or Windows 95/98. It is an simpler solution compared to the more complex

Windows Win32 COMM API.

Useful utilities such as diagnostic, monitor, and terminal emulator.

Illustrative sample programs,

!

Comprehensive on-line documentation.

PComm Installation

To install PComm, run \Setup.exe from the diskette enclosed in the package. Please note that the

PComm diagnostic and monitor utilities are for MOXA boards only; these two utilities will not work with other manufacturers serial boards.

After PComm is successfully installed, click on [Start], select [Program Files], and then PComm Lite group to select a list of utilities and documents.

PComm Programming Library

The serial communication library assists you in developing serial communications programs for any COM port that complies with Microsoft Win32 API. It facilitates the implementation of multiprocess and multi-thread serial communication programs and hence remarkably reduces development time.

This serial communication library provides a complete function library and sample programs for

Visual C++, Visual Basic, and Borland Delphi. To view detailed function descriptions and sample programs, click on [Start] " [Program] " [PComm Lite] " [PComm Lib Help], [PComm Porting

Notes] or [PComm Programming Guide], or refer to the sample programs in the PComm directory.

Utilities

In this section, we give brief descriptions of each utility. For more information about these utilities, see the on-line help from the software diskette.

Diagnostic (for MOXA boards only)

A convenient diagnostic program, ONLY for MOXA boards and ports, provides internal and

external testing of IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD, etc. It allows the user to check the function of both software and hardware.

To run the Diagnostic program, click on [Start]"[Program]"[PComm Lite]"[Diagnostic].

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.

To run the Monitor program, click on [Start]"[Program]"[PComm Lite]"[Monitor].

Troubleshooting

Common Smartio CP-104UL board errors and possible corresponding solutions are given below.

If the problem still cannot be solved after following these suggestions, 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 to receive faster technical support.

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. Please install the board in an empty PCI slot.

B. The board is not properly plugged into the system’s PCI slot. If that is the case, re-plug the board in a 32-bit PCI slot. It may also be the case that the PCI slot is defective. In this case, try other PCI slots until you find one that works.

C. The motherboard does not have an available IRQ for the CP-104UL board. Enter the PC’s

BIOS and make sure an IRQ setting is available in the PCI/PnP settings.

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 to see correct cable connection options.

B. The cable or the board are probably defective. Please try other ports, cables, or boards to verify this, or use the PComm Diagnostic utility to test MOXA board and port conditions.

If Diagnostic reports an error, replace the faulty components.

Software Causes and Solutions:

A. Smartio CP-104UL board 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 Cable and Cable Wiring chapter for proper wiring options, and check the line status of the suspected port using the diagnostic LED indicators on the mini tester.

B. The board’s control application might not be correctly written according to the corresponding API of the operating system. To verify the problem, run an existing application known to be good, or use utilities provided by Moxa, such as Pcomm Terminal

Emulator or HyperTerminal under Windows NT/2000/XP and Windows 95/98.

Windows NT

This section is specific for troubleshooting under Windows NT. For general problems and solutions, please 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 conflicts with another adapter. Check the PCI BIOS IRQ settings first, and then select an IRQ that is available.

2. After the system reboots, the error message, “Cannot find any configured MOXA

Smartio/Industio series board!” appears in the Event Log.

Make sure the PCI board is seated firmly in the expansion slot.

3. The COM number of the Smartio CP-104UL board (Bus No=x, Dev No=x,

Port1=COMx), with device number xx, conflicts with others.

The COM numbers for different boards are in conflict. Change the COM number mappings for the MOXA boards.

4. Windows NT system panics (blue screen).

The possible reason is an IRQ or I/O address conflict with other ISA Bus adapters, such as

LAN or SCSI boards, or with the system BIOS. Refer to the corresponding problem in the previous section, “General Troubleshooting,” for solutions.

Windows 95/98

This section is specific for troubleshooting under Windows 95/98. For general problems and solutions, see the section, “General Troubleshooting.”

1. The system fails to find the Smartio CP-104UL board!

C. The board(s) is (are) not properly plugged into the PCI slot.

D. The PCI slot is defective. Please try other slots until you find one that works.

E. The board itself might be defective.

2. After the system reboots, the error message “CP-104UL board(BusNo=x, DevNo=x,

Port1=COMx) interrupt number is invalid!” appears.

This indicates that the MOXA board was found, but the IRQ conflicts with another adapter.

Make sure the MOXA board’s IRQ does not conflict with another adapter’s IRQ. Check the

PCI BIOS IRQ settings and then select an available IRQ for the MOXA boards.

PCI

The 32-bit Smartio CP-104UL boards comply with PCI specifications 2.1. Hardware configuration for IRQ and I/O addresses is automatically assigned by the PCI BIOS. Hence, you must first plug in the board before installing the software driver.

Unlike ISA slots, different PCI slots in the same PC may have different bus numbers and device numbers with respect to the PCI specifications. The same PCI board will have different system configurations if moved to a different PCI slot. This is called slot-sensitive or slot-dependent, and may apply to PCI slots in PCs with different motherboards, which might use different device number sets. For example, some use 17, 18, 19, and 20 for identifying the respective PCI slots, whereas some use 11, 12, 13 and 14.

Due to this slot-dependency, it is necessary to re-configure the software driver once the board is plugged into a different PCI slot.

Up to 4 Smartio CP-104UL boards can be installed in one system. When installing more than one board, remember the order of boards to distinguish the installed boards.

MOXA UART

The MOXA UART is an intelligent asynchronous controller that supports one full duplex channel that simultaneously transfers data at a transmission speed of 921.6Kbps. To increase overall data

throughput, special features such as on-chip FIFO and on-chip hardware flow control are used to reduce the number of interrupts to the onboard CPU, and to prevent loss of valuable data.
