Secondly, select number of ports in the “Ports” field to match exactly the number of ports physically connected. Press Enter on the desired entry of the list to select.
file /etc/inittab which could also be manually modified by system administrator. Its value comes from the UNIX system “getty default” file, i.e., “/etc/gettydefs”. Modify this field to suit your need. 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.
Software Installation 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.

except flow control, thus non-terminal applications such as data acquisition will benefit from it, e.g. gain better throughput and performance. Response Three levels, Slow, Normal and Fast, of port response time are designed for your 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.
Software Installation Board Reset The board reset utility eliminates the need to shut down the UNIX system for reinitializing the Intellio C320Turbo/PCI board with new configuration. Press Enter to start board reset. 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 C320Turbo/PCI, including getty or tty monitor, are killed. Once the board is reset, the following message may show if it is successful.
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. Edit (e.g.
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 PComm 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.
Syntax for UNIX SVR4 #include #include #define MIBUFED struct strioctl int count; 0x401 ioc; /*number of bytes queued in the buffer */ ioc.ic_cmd = MIBUFED; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.ic_dp = (char *)&count; ioctl(moxa_fd, I_STR, &ioc); Note: Due to the characteristics of STREAMS driver, the returned count of bytes buffered only reflect the data buffered on MOXA board, not including the data buffered in STREAMS queue.
Serial Programming Tools 3. MTCRTS This function, only valid when hardware flow control is turned off (see MHWFLOW), is used to turn RTS on or off. Syntax for SCO UNIX/XENIX #define MTCRTS #define TurnON #define TurnOFF 0x403 1 0 ioctl(moxa_fd, MTCRTS, TurnON); ioctl(moxa_fd, MTCRTS, TurnOFF); Syntax for UNIX SVR4 #include #include #define MTCRTS #define TurnON #define TurnOFF struct strioctl int setting; 0x403 1 0 ioc; setting = TurnON /* or TurnOFF */; ioc.
Syntax for UNIX SVR4 #include #include #define MTCDTR #define TurnON #define TurnOFF struct strioctl int 0x404 1 0 ioc; setting; setting = TurnON /* or TurnOFF */; ioc.ic_cmd = MTCDTR; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.ic_dp = (char *)&setting; ioctl(moxa_fd, I_STR, &ioc); 5. MLOWATER Sometimes the application software may not be able to write any further data to the output buffer because of the output buffer being full.
Serial Programming Tools Syntax for SCO UNIX/XENIX #define MLOWATER int lowater; 0x405 /* low water value of output buffer (default = 512 bytes) */ ioctl(moxa_fd, MLOWATER, lowater); Syntax for UNIX SVR4 #include #include #define MLOWATER struct strioctl int lowater; 0x405 ioc; /* low water value of output buffer (default = 512 bytes) */ ioc.ic_cmd = MLOWATER; ioc.ic_timout = 0; ioc.ic_len = sizeof(int); ioc.ic_dp = (char *)&lowater; ioctl(moxa_fd, I_STR, &ioc); 6.
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, you might want to control the DTR or RTS signal, 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.
Serial Programming Tools 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.
Press Enter on the port, that the cursor stays, to view the port’s communication parameters, signal status, and input/output queue. 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.
Serial Programming Tools 1. Select and Press Enter on item “Communication Setup” to setup up all the communication parameters for connection. 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.

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.

C32020T Link Cable There are two different types of link cables: 25-signal-pin link cable and 10-signalpin link cable. The former is used when there is no external power applied to the external module (CPU/Basic Module). The latter is used when the external power is applied to the external module (CPU/Basic Module) if you have chosen to use Long Rang Extension Kit.
Connection Option and Cable Wiring 10-signal-pin Link Cable (for long range extension only) If the external power adapter is applied to the CPU/Basic Module, you will need to use the 10-pin cable accompanying with the Long Range Extension Kit. The Control Board to CPU/Basic Module should have only 10 signal pins with the following pinouts. Warning! Make the link cable carefully and precisely according to the following pinout, otherwise you will risk damaging the Control Board and CPU/Basic Module.
