    Introduction Comment: If you are using only the UNIX system for Intelligent Ports Card operation, you can skip this chapter and go to Chapter 3, “UNIX System Device Driver Installation.” If you plan to use MS-DOS under Simul-Task 386, follow the procedures in Chapter 3. The instructions in this chapter apply only to native MS-DOS.

  • Page 30: Installation Procedure

    Installation Procedure The following steps define the sequence of events for installing the IPC-1600 for use in the native MS-DOS environment. Read the entire procedure and supporting paragraphs before doing the installation. Write down the hardware parameter settings for each board to be installed as you read through the procedure the first time.

  • Page 31: Preconfigure The Ipc-1600 Boards

    Installation Procedure Preconfigure the IPC-1600 Boards Set the starting controller memory address (DS1, SW8—1), the I/O address (DS1, SW11—9), and the IRQ level (DS2, SW8—1) for each IPC-1600 to be installed. Note that IRQ levels are not used by the MS-DOS driver. Therefore all DS2 switches should be set to the OFF position (Note 2).

  • Page 32: Install The Hardware

    Installation Procedure Install the Hardware Refer to Chapter 4, “Hardware Installation,” and follow the instructions for the installation of the board. Ignore any instructions in Chapter 4 involving the DS1 and DS2 DIP switches, since they have already been done in this procedure.
  • Page 33 Installation Procedure Now, change directory (cd) to IPC and copy the files on the diskette in the “A” drive or in the “B” drive to the system disk drive as follows. The example uses the “A” diskette drive; the system disk is the “C” drive. Change directory to an optional separate directory to contain the IPC-1600 software.
  • Page 34 Installation Procedure Create or Modify the CONFIG.SYS File Use an editor, such as EDLIN, to change (or create) the CONFIG.SYS file in the root directory of the drive from which you boot MS-DOS. Add the following line to the CONFIG.SYS file if the IPC16DOS.SYS file is in a separate directory.

  • Page 78 Definition of IPC-1600 Device Node Names Software Device Class The /dev/ttyis xyy device type must be used for I/O devices (terminals, printers, MODEMs, etc.) when software flow control is desired. The ttyisxyy class of device node names does not support hardware flow control via the standard Electronic Industries Association (EIA) RS-232C hardware handshaking signals (CTS and RTS).
  • Page 79 Definition of IPC-1600 Device Node Names Hardware Device Class The ttyih xyy provides the standard EIA RS-232C hardware handshaking and monitors the following: Data Carrier Detect (DCD) Clear To Send (CTS) Ring Indicator (RI).

    IPC-1600 Diagnostics How to Run Diagnostics IPC-1600 diagnostics are run by executing the IPC16DIA program under native MS-DOS. There are six diagnostics which can be selectively executed from the IPC16DIA program. The program is terminated by the ESC key. Note that it is necessary to change the controller memory address assignment IPC-1600 boards set above 1MB to an address supported by diagnostics.

These tests write to memory, read the memory, and compare what is read to what was written. The IPC-1600 is held reset and the dual-ported memory is enabled during test execution.
  • Page 98 IPC-1600 Diagnostics IPC-1600 Communication Ports Tests The communication ports tests execute in both the host processor and the IPC-1600. These tests use the IPC-1600 FEPOS to exercise each port on the IPC-1600. A combination of four baud rate (1200, 9600, 19200, and 38400 bps), four data word sizes (5, 6, 7, and 8 bits), two stop bits (1 and 2), and three parity selections (none, odd, and even) are used to test each port.

  • Page 99: Helpful Hints

    Helpful Hints Typically, the lower interrupts on the Industry Standard Architecture (ISA) bus are used by other circuit boards in the system. Therefore, to prevent configuration conflicts, try using some of the higher interrupts (IRQ 10, IRQ 11, and IRQ 15) for the Intelligent Ports Card. Make sure that the Intelligent Ports Card is installed in a 16-bit or a 32-bit ISA-compatible bus slot.
  • Page 100 Helpful Hints When using a Hayes* compatible MODEM, dial out once to configure the MODEM before caIling into the MODEM. The AT&T 446 Laser Printer and the HP† LaserJet Series II printer must be installed on a serial port configured as a ttyih xyy device under the UNIX system.

General Instructions The general sequence to install the IPC-1600 ports cabinet is as follows. Decide where and how to mount the cabinet.
  • Page 148 Installation Information Choosing a Mounting Location The AT&T IPC-1600 Ports Cabinet must be located within about 7 cable feet (2 meters), the length of the fanout module cable assembly, of the host machine. The method of mounting (floor, table, or wall) is a matter of convenience for your particular installation.
