Software Installation DOS With over ten years of professional expertise in serial communications, Moxa provides high-performance DOS device drivers and powerful library functions, which are integrally called DOS API-232. MOXA DOS device driver supports maximum of 256 serial ports. In this chapter, driver installation, setup, loading and unloading procedures are described. Device naming issue is discussed.
After installation is complete, you will be prompted to proceed running setup program. It is strongly recommended to do so.
Software Installation Driver Setup The following are steps for configuring the Intellio C320Turbo boards and setup the driver. Note that it is not intended to illustrate all the convenient functions of the setup programs when configuring the boards. Please refer to the F1 on-line help instructions as running setup program. 1. Run the setup program, BIN\SETUP.EXE, in the API-232 directory. You will see the first “MOXA C218/C320” dialog probably with no board installed if it is the first time configuration.
2. First, press Enter on the board type field to specify the board type, C320T u r b o . 3. Now the default base memory address and IRQ of the desired Intellio C320Turbo board will be shown along with default port number range.
Software Installation Legend Board Type: Ports: Port number: Choose the board type, C320Turbo. The number of ports for C320Turbo, which is 8. This is actually the port ID of each port. The application software will refer to the port by its port number (ID). Duplicated port number is not allowed. Memory Bank: Base memory address of the board. Duplication is not allowed. Interrupt no.: The IRQ number of the board. All C320T u r b o boards will share one same IRQ.
Legend: Some noticeable fields and functions are explained below. On board TxD buf: On board RxD buf: External RxD buf: F5: Group edit: The transmit (output) buffer already allocated on the C320Turbo board for each port. Cannot be altered. The receive (input) buffer already allocated on the C320 Turbo board for each port. Cannot be altered. Extra receive (input) buffer you wish to allocate for each port. This will consume the DOS conventional memory. Default value is 0.
Software Installation Driver Loading Having completed the setup, you can load the driver, “BIN\MX-DRV.EXE”, at the DOS prompt. The driver will detect the Intellio C320Turbo automatically. If the board(s) is(are) detected, a message similar to below will show: API-232 Version x.x MOXA Intellio ISA series communication driver Setup driver … C320 Turbo board 1: Bank [xxx] IRQ x Port [1-8] Device driver setup O.K. It means the Intellio C320Turbo driver is installed properly.
MOXA Serial Port Names Each MOXA serial port is referenced as port number in terms of programming. The port numbers are automatically assigned, once the port numbers are decided when configuring the ports of the board. For example, if 8 ports are configured and the starting port number is 1, then the mapping of serial port numbers will be as depicted in the following picture.
Software Installation Windows 3.x For users who need to implement an industrial control system or data acquisition system in the Windows 3.x environment, Moxa has developed two device drivers and/or library functions under Windows 3.x which is called Windows 3.x API-232. You should find the Dos/Windows 3.x driver diskette along with shipment in addition to API-232 User's Manual. In this chapter, driver installation and configuration procedure are described.
MOXA Windows-compatible COMM Driver Due to the limitations of Windows 3.x operating system itself, only up to 9 COM ports are supported, i.e., COM1 to COM9. Hence, Intellio C320Turbo with 8 ports is a suitable choice. After successful installation, a program group will be created which contains all the useful programs Moxa provided. Restarting of Windows 3.1 system is required for MOXA Standard Windows-compatible COMM Driver after installation. When system restarted, the MOXA COMM Driver is ready to go.
Software Installation COM 2 1 COM 3 2 COM 4 3 COM 5 4 P1 COM 7 COM 8 COM 9 To Control Board To next module COM 6 5 P8 6 From PC 7 COM 8 9 COM 8 COM 7 COM 6 UART Module COM 5 COM 4 COM 3 COM 2 I8 DC IN ON/OFF Basic Module CPU Module Utilities The utility, TTY, is included to help users monitor and debug RS-232 communications under Windows 3.x which can manipulate ports from COM1 to COM9.
standard might not be able to operate MOXA COM ports. For instance, LapLink for Windows accesses I/O address directly which will fail with the Intellio C320Turbo because C320Turbo is accessed via memory instead of I/O port. MOXA Proprietary Windows DLL Driver For MOXA Proprietary DLL Driver, MOXA API-232 library functions are supported for programming, instead of Windows COMM API.

API-232 functions, such as sio_open(), sio_read() and sio_write(), could be used in a way that is mostly like DOS API-232 programming.
Visual Basic are supported in the driver file directory after driver installation. In addition, for Windows C language only, there are also Modem Control and File Transfer library available, supporting Hayes compatible modem control as well as ASCII, KERMIT, XMODEM, YMODEM, and ZMODEM file transfer protocol functions. For complete Windows 3.x API-232 function description, see API-232 User's Manual or file API-232.TXT in the API-232 library for more details. The following functions are for Windows 3.x only.
4 4 Serial Programming Tools Moxa supports powerful but easy serial programming library and utilities under Windows NT, Windows 95/98 and UNIX. You will greatly save the developing time with the MOXA Serial Programming Tools. The following sections details the installation, the library and the utilities under various O.S. platforms.
PComm Programming Library The serial communication library is to assist you to develop programs for serial communications for any COM port complying with Microsoft Win32 API. It can ease the implementation of multi-process and multi-thread serial communication programs and hence greatly reduce the developing time. For complete library function description and example programs for Visual C++, Visual Basic and Delphi, please see help file and example programs in P C o m m directory for more details.
Serial Programming Tools Monitor (for MOXA boards under Windows NT Only) A useful port status monitoring program allows you to watch the selected MOXA COM ports’ data transmitting/receiving throughput and communication line status which are updated and displayed on the screen at every time interval. In addition, you may click on one of the specific displayed port in order to see the current communication parameters and status of that port.
Terminal Emulator The Terminal Emulator features multi-windows and supports terminal types of VT100 and ANSI. You can transfer data interactively, send pattern periodically or transfer file using ASCII, XMODEM, YMODEM, ZMODEM and KERMIT protocols.
Serial Programming Tools UNIX Programming the MOXA Ports The system calls that apply to standard tty port also apply to MOXA port since MOXA port conforms to UNIX tty standard. System calls are like open(), ioctl(), read(), write(), close(), etc. Please refer to your UNIX Programmer's Reference manual. However, these system services only provide limited functions and thus may not satisfy the sophisticated programmers’s need.

Connection Option and Cable Wiring RS-422 Impedance Matching When an electrical signal travels through two different resistance junctions in a transmission line, the mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which in turn will contribute communication errors. The solution to this problem is to establish the same impedance at the line ends as in the line itself by terminating them with resistors.

6 6 Troubleshooting Common C320Turbo problems and possible solutions are listed below. If you still have problems, contact your dealer or Moxa for help. Or report it using “Problem Report Form” to your dealer at once for technical support. 1. MOXA board not found. Hardware causes and solutions: a. The base address you have selected is conflicting with the BIOS shadow RAM or cache. Please disable the area for board.
e. Sometimes it happens when the total consumption of power in the system is higher than the power supply can provide. Especially when many interface boards including board(s) are plugged in the system. It is recommended to replace the current power supply with higher watt one. Or choose the external power option if Intellio C320Turbo is used. Software Causes and Solutions: a. Under DOS/Windows 3.
Troubleshooting c. IRQ settings of software and hardware do not match. 3. “CPU/Basic Module not found” message. Or CPU/Basic Module can not download firmware from the Control Board. Hardware Causes and Solutions: a. Power off the CPU/Basic Module and Control Board system. Check that the connection cable between the CPU/Basic Module and the Control Board is correct and firmly plugged in on both sides. Power on the CPU/Basic Module and wait until the LED display reads “Ld”. Power on the Control Board system.
Hardware Causes and Solutions: If the error message persists after check, return the unit for repair. As “E0”, “E1” or “A1” occurs, usually you have to turn off and on the CPU Module. If problem persists, the CPU Module might be defective. As “E2” occurs, turn off the CPU Module, firmly connect the UART Modules, and turn the power back on. As “E4” occurs, usually you have to turn off the CPU/Basic Module, then turn on at least time interval 3 seconds.
Troubleshooting 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 system starts, error message “MOXA C320Turbo Multiport Board #1 addr(XXX): CPU/Basic Module not found!” appears in Event Log.
