1-2 IPC-1600 USER’S GUIDE

What Is an IPC-1600?

The AT&T Intelligent Ports Card, Model 1600 (IPC-1600) is a sixteen port, intelligent, serial Input/Output (I/O) controller with an 80C186 16-bit microprocessor running at 12.5 MHz. The sixteen RS-232, asynchronous ports are wired to RJ-45 (10-pin) fanout modules via two 80-conductor ribbon cables.

The IPC-1600 operates with the AT&T UNIX System V/386 Release 3.2

and later releases on the following machines:

■

AT&T 6386E Work Group System

■

AT&T 6386/25 Work Group System

■

AT&T 6386E/33 Work Group System

■

AT&T 6386E/33 Work Group System Model S.

The IPC-1600 growth kit (COMCODE 405980145) provides the following:

■

One AT&T IPC-1600 board (COMCODE 405977729).

■

Mounting hardware consisting of a mounting bracket and two

2.25-inch, long-shank screws (COMCODE 406112680).

■

One AT&T Intelligent Ports Card, Model 1600 (IPC-1600) User’s Guide, Select Code 305-920 (COMCODE 105747182).

■

One AT&T IPC-1600 to 16-ports fanout cable assembly (COMCODE 405980178) which provides two 7-foot (2 meters) long, 80-conductor cables for connecting an IPC-1600 board to a 16-Ports Fanout module.

■

One 16-Ports Fanout module providing sixteen 10-pin RJ-45 type modular connectors (COMCODE 405977869).

Note: Separately orderable modular cables and adapters are

necessary to connect I/O devices to the serial ports. See Appendix B, “Serial Input/Output Device Interface” for modular cable and adapter information.

1-4 IPC-1600 USER’S GUIDE

IPC-1600 Architecture

The architecture of the IPC-1600 provides many useful and powerful

multiuser capabilities under the UNIX system. Furthermore, single-user

applications using the IPC-1600 for general-purpose I/O, as well as for industrial control, can be done under MS-DOS.

IPC-1600 features include the following:

■

One 80C186 16-bit microprocessor (12.5 MHz).

■

Industry Standard Architecture (ISA) bus connectors (any 16- or 32-bit slot can be used).

■

One host Interrupt ReQuest (IRQ) level can be shared per 16 ports or one IRQ level can be assigned for all IPC-1600s (maximum of 7 boards

[112 ports]).

■

A 64-KB dual-ported Static Random Access Memory (SRAM) is used for data storage and buffering. This SRAM provides communications and control between the host processor and the IPC-1600 microprocessor. The host processor address range for this space is on 64KB boundaries and is switch selectable. This SRAM is “zero-wait-state” to the IPC-1600 microprocessor.

■

A 16KB RAM for local programs.

■

The use of a 16-bit data transfer on the Industry Standard Architecture (ISA) bus for maximum efficiency.

Chapter 6, “System Features,” provides more detailed information.

OVERVIEW 1-5

Ports and Drivers

The software that takes care of the I/O tasks between the user terminals/MODEMs/printers and the UNIX system is built into the IPC-1600 firmware to increase the UNIX system performance. End users get the benefit

of immediate keyboard/screen response and the enhancement of the overall performance of the UNIX system. The UNIX system driver supports the 8-bit character set.

The MS-DOS device driver supports an 8-bit character set and the

MS-DOS level interface.

MS-DOS and UNIX System IPC-1600 Use

Strategy

Native MS-DOS and UNIX System Operation

Requirement:

If you plan to use both the native (boot) MS-DOS and the UNIX system

for the operation of the IPC-1600, proceed as follows.

Follow Chapter 3, “UNIX System Device Driver Installation,”

procedures with the following recommendations.

Install the IPC-1600 board(s) using controller memory address

❑

space below 1MB.

❑

Configure multiple IPC-1600 boards to share one Interrupt ReQuest (IRQ) level and share the same 64-KB controller memory address space.

The host computer must be set up to have base memory above 512KB (512KB to 640KB) disabled for the IPC-1600 to use controller memory starting addresses 080000h or 090000h. Refer to the customer documentation that came with your AT&T Work Group System (WGS) for information on how to disable base memory.

After installing hardware (Chapter 4), install MS-DOS software starting with Step 3 in Chapter 2. Be sure to specify same controller memory starting address and I/O address(es) that were set when installing the UNIX system device driver and IPC-1600 hardware.

OVERVIEW 1-9

MS-DOS and UNIX System IPC-1600 Use Strategy

MS-DOS Under Simul-Task and UNIX System

Operation

If you plan to use MS-DOS under Simul-Task 386 or to use only the

UNIX system for the operation of the IPC-1600, skip Chapter 2. Start with Chapter 3, “UNIX System Device Driver Installation,” and follow the

instructions for the installation of the software. Then install the IPC-1600 board per Chapter 4, “Hardware Installation.”

Native MS-DOS Operation

If you plan to use only native MS-DOS for the operation of the IPC-1600s, start with Chapter 2, “MS-DOS Device Driver Installation,” and follow the instructions for the installation of the software and hardware. Skip Chapter 3.

1-10 IPC-1600 USER’S GUIDE

Chapter 2: MS-DOS Device Driver Installation

Introduction

Comment:

This chapter provides instructions on how to install the MS-DOS device driver and diagnostics, which are on the diskette labeled “Intelligent Ports

Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0.” Refer to Chapter 6, “System Features,” for information about the software support offered through the MS-DOS device driver.

Note:

The Intelligent Ports Card MS-DOS device driver supports the MS-DOS level interfaces in such a way that virtually any software application can access all serial I/O ports provided by the IPC-1600.

The same software is supplied on both a 5.25-inch diskette and a 3.5-inch diskette.

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. See the section, “IPC-1600 Diagnostics,” in Chapter 7 for diagnostics information.

Requirement 1:

Requirement 2:

The IPC-1600 board(s) must be installed and the I/O address, starting controller memory address, and IRQ level initially set before executing the

IPC16CNF program.

Each board in the system must be assigned an I/O address and the same starting controller memory address. The hardware Interrupt ReQuest (IRQ) level switches are all set to OFF unless the UNIX system is also being used to operate the board, in which case the UNIX system switch setup takes precedence. If you assign different controller memory addresses to IPC-1600s, only one board at a time can be used under native MS-DOS.

MS-DOS DEVICE DRIVER INSTALLATION 2-1

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. Then refer to these notes when you do the procedure.

Step 1:

Step 2:

Step 3:

Step 4:

Step 5:

Step 6:

Step 7:

Preconfigure the IPC-1600 boards by setting the DIP switches for a unique I/O address, a starting controller memory address, and IRQ level.

Install the hardware (IPC-1600 boards) using the instructions in Chapter 4, “Hardware Installation.”

Power up the system and load the files on the “Intelligent Ports Card (IPC-1600) MS-DOS Device Drivers and Diagnostics, Version 1.0” diskette.

Create or edit the CONFIG.SYS file using an editor such as EDLIN to include the DEVICE=\IPC\IPC16DOS.SYS entry.

Execute the IPC16CNF program to configure the IPC-1600 and

configure the driver. Reconfigure the IPC-1600 DIP switches if necessary to match the

software assignments. Reboot the machine to install the driver.

The following paragraphs provide more information for each of the installation steps. Note that Steps 5 through 7 can be executed when necessary to reconfigure the driver and/or port characteristics.
