UNIX There are various UNIX operating systems, such as SCO UNIX, UNIX SVR4.2, XENIX and Solaris, etc. Different types of UNIX drivers are required for different UNIX. Moxa supports device drivers currently for SCO UNIX, UNIX SVR4.2 and XENIX. . In this section, driver installation procedure is described. Administration utility, mxadm, is explained, which is for configuration, monitor and terminal emulation. Related issues such as device naming, baud rate settings and terminal enable are stated.
Software Installation 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. /dev/fd096ds15 (A: 1.2 MB) 3. /dev/fd1135ds18 (B: 1.44MB) 4. /dev/fd196ds15 (B: 1.2 MB) 5.
For more details, see later section “Administration Utility -mxadm”. Up to now, you have already completed the whole installation and the Intellio C218Turbo/PCI board is ready to work. Note! Please double check if all the Intellio C218Turbo/PCI components: Control Board, link cable and external modules, are connected and fastened tightly in order to ensure the system and driver will start successfully later. Now you can run any ready-made applications such as getty terminal or PPP/SLIP.
Software Installation MOXA TTY Device Naming Convention If the Intellio C218Turbo/PCI 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 physical 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.
Administration Utility - mxadm You can use the administration utility, mxadm, to change the Intellio C218Turbo/PCI 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". Basic Configuration This utility is to configure basic settings for the driver.
Software Installation In the “Basic Configuration” dialog, you should first press Enter in board type field to select board type, C218Turbo/PCI. And then a list of Intellio C218Turbo/PCI boards found available is popped up for you to select. Normally, one choice is available if there is one Intellio C218Turbo/PCI board installed beforehand. Press Enter on the desired entry of the list to select.
Advanced Configuration This is to provide advanced settings for advanced driver features beyond basic settings described in the previous Basic Configuration. Similarly, in “Board Settings” dialog, board reset (described later) is available for the latest configuration to take effect without kernel rebuilding and system reboot. 1. In the “Advanced Board Configuration” dialog, you can press Enter in each field to select the desired option. The fields are details as follows.
Software Installation 2. Press PageDown to enter “Advanced Port Settings” sub-dialog, there are some noticeable fields for initialize the ports for advanced usage. You may skip this step if you do not concern these features. 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.
Response Three levels, Slow, Normal and Fast, of port response time are designed for user's need. Ports with faster response time will consume more host CPU's resource while slower response consumes less resource. The response time for those ports with normal or slow response can be further tuned by the response level in “Performance Tuning” menu. In addition, if the port feature is set to On-board Line Discipline “Disable” and Feature “Terminal”, response option will be locked at "Slow" level.
Software Installation 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.
However, before the board reset is issued, you must make sure that 1. All enabled ports must be disabled. 2. All processes related to the Intellio C218Turbo/PCI, including getty or tty monitor, are killed. Once the board is reset, the following message may show if it is successful. MOXA Serial I/O Board (Ver x.x) Downloading MOXA-C218Turbo/PCI (MemBank=XX000;BusNo=X;DevNo=X) is found. If one of the following message appears, please see Chapter "Troubleshooting".
Software Installation 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 Following procedure is how to set the MOXA port to the “Terminal” for login purpose, taking ttya11 as an example, SCO UNIX/OpenServer/Open Desktop/XENIX # enable /dev/ttya11 UNIX SVR4.2 and UnixWare 1. 2. 3.

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 will details the installation, the library and the utilities for various O.S. 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 co3nvenient 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 Syntax for SCO UNIX/XENIX #define MIBUFED 0x401 int count; /* number of bytes queued in the buffer */ ioctl(moxa_fd, MIBUFED, &count); Syntax for UNIX SVR4 #include #include #define MIBUFED 0x401 struct strioctl ioc; int count; /* number of bytes queued in the buffer */ ioc.ic_cmd = MIBUFED; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.
ioc.ic_cmd = MOBUFED; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.ic_dp = (char *)&count; ioctl(moxa_fd, I_STR, &ioc); Note: See MIBUFED for influence of STREAMS driver. 3. MTCRTS This function, only valid when hardware flow control is turned off (see MHWFLOW), is used to drive RTS signal on or off.

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 4-14 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 RS-485 Programming for Opt8J If you intend to do RS-485 communication with Opt8J, please follow the RS-485 programming guide below and also refer to Chapter “Connection Option (Opt8x) and Cable Wiring” for more Opt8J RS-485 operation details. 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. The port switch of each port should be set to On position.
Solution 2 There's a dedicated RS-485 function in PComm library. It integrates the above functions of solution 1 regarding sending data as one. sio_putb_x(port, buff, tick ); /* 1. Turn on RTS and ready for transmitting data. 2. Send data. 3. Wait for tick time. 4. Turn off RTS and ready for receiving data. */ For more information on these functions, please refer to PComm library on-line Help file for Windows NT and Windows 95/98.

RS-485 Cable Wiring for Opt8J One RS-485 connection box designed for Intellio C218Turbo/PCI is: Opt8J: Connection box with 8 female RS-422/485 DB25 ports. Set the port switch to ON position. 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.
Connection Option (Opt8x) and Cable Wiring 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.
