Software Installation UNIX There are various UNIX operating systems, such as SCO UNIX, UNIX SVR4.2, and Solaris, etc. Different types of UNIX drivers are required for different UNIXs. Moxa supports device drivers currently for SCO UNIX, UNIX SVR4.2, and XENIX. In this chapter, driver installation procedure is described. Administration utility, mxadm, is explained, which is for configuration, monitor and terminal emulation.
Follow the instructions prompted to finish the driver installation Copyright (C) 1999 Moxa Technologies Co., Ltd. All Rights Reserved. MOXA UNIX Device Driver Installation Ver. x.x Please select one of the following OS: 1. SCO UNIX 2. UNIX SVR4.2 3. XENIX Select: Please type 1 for SCO UNIX 3.2.x, SCO OpenServer or SCO Open Desktop. Type 2 for UNIX SVR4.2, UnixWare or MITUX. Type 3 for XENIX. Please select one of the devices where the driver diskette/files put: 1. /dev/fd0135ds18 (A: 1.44MB) 2.
Software Installation Step 7. After system rebooted, please run “mxadm” to configure the board and port settings. Select and open “Basic Configuration” to do basic board and port configuration. You may further optionally select and open “Advanced Configuration” to do advanced settings. Select and open “Board Reset” to reset the driver and board for the latest configuration to take effect. For more details, see later Section “Administration Utility “mxadm””.
MOXA TTY Device Naming Convention If the C218Turbo is successfully configured, there will be two tty devices created for each port at /dev directory: one is non-MODEM tty (e.g. ttya11), and the other is MODEM tty (e.g. ttyA11). The two devices are actually accessing the same port except that the MODEM tty has to check the ON status of DCD signal to be able to open device, and closing device automatically as DCD signal is OFF.
Software Installation Administration Utility “mxadm” You can use the administration utility, mxadm, to change the C218Turbo basic and advanced configuration, to reset the board, to tune performance and to remove the installed MOXA driver from the UNIX system, which are detailed as follows. For the details of the rest utilities: port monitoring, and terminal emulator, please refer to Section “UNIX” of Chapter “Serial Programming Tools”.
In the “Basic Configuration” dialog, you should first press Enter in board type field to select board type, C218Turbo. Then press Enter in Memory field to select desired base memory bank. 2. Press PageDown to enter “getty Setting” sub-dialog, there are some noticeable fields for initialize the port for getty usage. You may skip this step if you will not use getty utility. Non-Modem and Modem Baud Rate This field stands for the initial baud rate symbol and hunt sequence for Non-Modem /Modem tty.
Software Installation In some cases, you may need to modify the “getty default” file as well. For example, in some UNIXs, the “9600” symbol indicated 8-data-bit no-parity while in others it may stand for 7-data-bit, even-parity. So, please examine the “getty default” file carefully, and make sure the terminal settings is the same. Otherwise, garbled data will be inevitable.
Baud Rate Mapping This advanced feature is set to “High Band” by default, indicating that the baud rate 50, B50, will no longer stand for 50 bps. Instead, B50 means 57600 bps, B75 is for 115.2 Kbps, B110 is for 230.4 Kbps, and B134 is for 460.8 Kbps, and B150 is for 921.6 Kbps. You may press F1 Help for on-line details. If this feature is set to “Low Band”, the original definition of UNIX baud rate mapping are used. 2.
Software Installation Feature In “Port Feature Settings” sub-dialog, port feature [Terminal] is the only choice if On Board Line Discipline is set to “Enable”. This is good for terminal application users. However, if On Board Line Discipline is set to “Disable”, port feature could be either [Transparent] or [Terminal]. In case of [Terminal], all the tty line discipline jobs will be done on host which surely is a burden to the host.
Performance Tuning The utility let you tune the favored response time for those ports with Resp = Norm or Slow in [Port Feature] sub-menu of Advanced configuration. Ten response time levels (0-9) are available for tuning. The idea is that the faster response time will consume more host CPU resource while slower response consume less resource. If the host CPU is fast enough or a quick response is highly demanded, choose level 9 would be suitable.
Software Installation However, before the board reset is issued, user must make sure that 1. All enabled ports must be disabled. 2. All processes related to the C218Turbo, including getty or tty monitor, are killed. After board reset, the following message may show if it is successful. MOXA Serial I/O Board (Ver x.x) Downloading MOXA-C218Turbo (MemBank=XX000) is found. If one of the following messages appears, please see Chapter “Troubleshooting”.
Checking Board Initialization Status When the system starts up and enters into the multiuser mode, you should see the board initialization status report, which is same as one of the messages described in the “Board Reset” part of previous Section. Setting MOXA Ports to Terminal To enable the “Terminal” port for login purpose, taking ttya11 as an example, SCO UNIX/OpenServer/Open Desktop/XENIX, # enable /dev/ttya11 UNIX SVR4.2, UnixWare and MITUX, 1. 2. 3. Edit (e.g. use vi editor) the file /etc/inittab.
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. Driver Setup The following are steps for configuring the C218Turbo 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.
Software Installation 2. First, press Enter on the board type field to specify the board type, C218Turbo. 3. Now the default base memory address and IRQ of the desired C218Turbo board will be shown along with default port number range.
Legend Board Type: Ports: Port number: Choose the board type, C218Turbo. The number of ports for C218Turbo, 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 C218Turbo boards will share one same IRQ.
Software Installation Legend: Some noticeable fields and functions are explained below. On board TxD buf: The transmit (output) buffer already allocated on the C218Turbo board for each port. Cannot be altered. On board RxD buf: The receive (input) buffer already allocated on the C218Turbo board for each port. Cannot be altered. External RxD buf: Extra receive (input) buffer you wish to allocate for each port. This will consume the DOS conventional memory. Default value is 0.
5. To setup more boards, please follow the same instructions 2 to 4 described above. The maximum supported number of C218Turbo boards is 4 in one system under the DOS system as long as free ISA slots are available and IRQ and Memory resources are not used up. Driver Loading Having completed the setup, you can load the driver, “BIN\MX-DRV.EXE”, at the DOS prompt. The driver will detect the C218Turbo automatically. If the board(s) is(are) detected, a message similar to below will show: API-232 Version x.
Software Installation If something went wrong, for instance, the board does not match the configuration or the board is missing, the screen will show a message like: API-232 Version x.x MOXA Intellio ISA series communication driver Setup driver … C218Turbo board 1: Bank [xxx] not found! Driver execution failure! It means the C218Turbo driver is not installed properly. Please refer to Chapter “Troubleshooting” for possible reasons and solutions.

4 4 Serial Programming Tools Moxa supports easy but powerful serial programming library and communication troubleshooting utilities under Windows NT, Windows 95/98, UNIX, and DOS. You will save greatly the developing time, using MOXA Serial Programming Tools. The following sections will details the installation, the library and the utilities for various platforms.
PComm Programming Library The serial communication library is to assist users 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 PComm directory for more details.
Serial Programming Tools Diagnostic (for MOXA boards only) A convenient diagnostic program provides internal and external testing, such as IRQ, TxD/RxD, UART, CTS/RTS, DTR/DSR, DTR/DCD testing, etc., for the MOXA boards and ports to verify correct operation of both the software and hardware.
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.
Serial Programming Tools 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.
UNIX Programming the MOXA Ports The system calls that apply to standard tty port can also be applied 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' need.

Serial Programming Tools 7. MHWFLOW This function is used to enable/disable hardware flow control. The first open() function of a port will set the hardware flow control bits on or off depending on the [RTS/CTS Hardware Flow Control] configuration in mxadm. However, users might want to control the DTR or RTS signal on their will, thus the RTS flow control bit should be turned off (HWFLowControlOff) in order to take over the control of DTR or RTS signal via function MTCRTS or MTCDTR.
Utilities You can use the administration utility, mxadm, to monitor port activity and to do terminal emulation, which are details as follows. Port Monitoring This utility gives you a quick view about all the MOXA ports' activities. You can easily learn each port's total received/transmitted (Rx/Tx) character count since the time when the monitoring is started. Rx/Tx throughputs per second are also reported in interval basis (e.g.
Serial Programming Tools Terminal Emulator This utility provides data sending and receiving ability of all tty ports, especially for MOXA ports. It is quite useful for testing simple application, for example, sending AT command to a modem connected to the port or used as a terminal for login purpose. Note that this is only a dumb terminal emulation without handling full screen operation. Besides, data scope function with pattern/file transfer is provided. 1.
2. Select and enter “Terminal” to enter terminal emulation. Or select and enter “Advanced Transfer Modes” to perform pattern or file transfer with protocols such as ZModem.
Serial Programming Tools DOS Installation API-232 Library is the professional serial programming tool for DOS. It is installed automatically along with the MOXA DOS drivers. The installation is detailed in Chapter “Software Installation”. DOS API-232 Library DOS API-232 library supports languages like Microsoft C, Turbo C, Macro Assembly, QuickBasic, Turbo Pascal, Clipper, etc. Sample programs for each supported language are included, and placed in the sub-directory ..
Data Scope The Data Scope, BIN\SCOPE.EXE, is a suite of utility programs that can help users with system troubleshooting and serial communication debugging. There are three major functions in Data Scope utility: 1. The Data Scope utility offers transparent monitoring of serial communication lines and allows data to be streamed to disk storage for later analysis. 2.
Serial Programming Tools Diagnose The Diagnose, BIN\DIAGNOSE.EXE, is a utility that can help users to diagnose the hardware condition of each port of the selected board. See on-line help for more details. Before executing it, please remove the Moxa driver in advance via executing “Mxdrv/Q” if the Moxa driver is running in the background.

Connection Option (Opt8x) and Cable Wiring RS-485 Cable Wiring for Opt8J One RS-485 connection box designed for C218Turbo is: Opt8J: Connection box with 8 female RS-422/485 DB25 ports. Set the port switch to ON position (RS-485) for the desired port(s). The Opt8J supports only 2-wire half-duplex RS-485 communication. Data+/- pins are served for both data transmitting and receiving, depending on the RTS signal.
RS-422/485 Impedance Matching For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance 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.
