Introduction

The Epson® Equity® 286 PLUS is a high-performance personal

computer which offers exceptional speed and convenience in a compact design. The computer’s 12 MHz 80286 microprocessor makes all your programs run faster, even when supporting multitasking operations.

Your system includes 1MB of internal memory, a built-in VGA

(video graphics array) display adapter, built-in parallel and serial interfaces, an IBM®PS/2™ compatible mouse port, and four

standard option slots (three 16-bit and one 8-bit). These

interfaces allow you to connect most of your peripheral devices directly to the computer, so you do not have to install option cards. You can use the option slots to install additional devices, such as a modem or a network card.

Your computer can support up to three internal drives: either two diskette drives and one hard disk drive, or one diskette drive and two hard disk drives.

The Equity 286 PLUS also offers shadow RAM to speed up

processing by moving the ROM BIOS and the video ROM into the RAM area of memory. This allows the computer to access

information and display text and graphics on the screen faster.

Optional Equipment

You can easily upgrade your computer by installing additional

memory and adding just about any optional device that is compatible with the IBM Personal Computer, PC XT,“’ or PC AT.™

Introduction I

By adding memory modules to the main system board, you can expand the computer’s memory up to 5MB. Memory modules are efficient because they eliminate the need to use one of your option slots to add memory to your system. Your computer can

also access memory installed on memory modules faster than memory installed on an option card. You can add a memory card, however, if you want to expand your memory up to 16MB.

You may also want to install an 80287 math coprocessor in your computer to speed up mathematical calculations in certain application programs. Check with your authorized Epson dealer to see which options are available.

Operating Systems and Other Software

You probably have a version of MS-DOS® to use with your’ Equity 286 PLUS. Epson has enhanced MS-DOS by adding two time-saving utilities-HELP and MENU-that make it easier to use. The HELP program lets you display information on the screen about any MS-DOS command. MENU provides an easy way to run many of these commands.

Note MS-DOS is not the only operating system you can use with your computer. You can run practically any operating system

compatible with MS-DOS, OS/2, Unix® or XENIX® If you use another operating system, however, refer to the documentation that came with it to install and run it on your

computer.

You can use virtually any application program designed for the

IBM PC, PC XT, PC AT, or compatible computers on your Equity 286 PLUS.

Epson has included special VGA utilities that you can use with your built-inVGA adapter. These utilities provide 132-column text mode and emulation of different adapter types, as well as a program to turn off your display automatically when you’re not using it.

How to Use This Manual

This manual explains how to set up and operate your

computer, install options, and run diagnostics checks. Although the illustrations show a computer with a 51/4-inch diskette drive, instructions are included for using a 31/2-inch drive.

Note

4 lntroduction

Chapter

Setting Up Your System

Setting up your Equity 286 PLUS personal computer is easy.

Just follow the eight steps in this chapter. As you set up your

computer, you may want to leave this manual’s back cover foldout open so you can refer to the illustrations identifying the different parts.

Note The illustrations in this manual show the computer with a 5 1/4-inch diskette drive. If your system has a M-inch diskette drive instead, and you need additional instructions, see Chapter 3 when necessary.

Choosing a Location

Setting Up Your System

1-1

Before you set up your computer, it’s important to choose a safe,

convenient location that provides the following:

A large, sturdy desk or table. The surface should be strong enough to easily support the weight of your system and all of

its components. Select a location that allows plenty of space

so you can work comfortably.

A flat, hard surface. Soft surfaces like beds and carpeted floors attract static electricity, which can erase data on your

disks and damage the computer’s circuitry. Soft surfaces also prevent proper ventilation.

Good air circulation. Air must be able to move freely under the system and behind it. Leave several inches of space around the computer.

Moderate environmental conditions. Protect your computer from extremes in temperature, humidity, dust, and smoke. Avoid direct sunlight or any other source of heat. High humidity also hinders operation, so select a cool, dry area.

Appropriate power sources. To prevent static charges,

connect all your equipment to three-prong, 120-volt grounded outlets. You need one outlet for the computer, one

for the monitor, and additional outlets for a printer and any

other peripheral devices.

No electromagnetic interference. Locate your system away

from any electrical device, such as a telephone, which

generates an electromagnetic field.

1-2

Setting Up Your System

3 Removing the Protector Card

If you have a 5 1/4-inch diskette drive, there is a protector card in

the diskette slot. This card is inserted at the factory to protect the read/write heads in the drive. To remove it, flip the latch up to pop the card out part way, then pull it out, as shown below.

(If you have a second 5 1/4-inch diskette drive, be sure to remove the protector card from that drive as well.)

Save the protector card. If you transport your computer, you may want to insert the card into your diskette drive prior to shipping. This will protect the read/write heads during the shipping process.

Setting Up Your System

I -3

Connecting a Monitor

The procedure you use to connect your monitor to the computer depends on the type of monitor you have. If you have a VGA monitor (or a multi-frequency monitor with an analog

connector), you can connect it to the computer’s built-in VGA port. See “Using the VGA Interface” below. If you have any other type of monitor, see “Using a Display Adapter Card”

below.

Using the VGA Interface

Follow these steps to connect your VGA monitor to the VGA

port on the computer:

Make sure your monitor is turned off.

1. Place your monitor on top of or near the computer. For easy

2. access, turn the monitor and computer around so the backs of both components are facing you.

If necessary, connect the monitor cable to the monitor.

3. (Your monitor may have a permanently attached cable.)

1-4

Setting Up Your System

Examine the connector end of the monitor cable, and position the plug to match the orientation of the monitor port (marked with a monitor icon). Then insert the plug

into the port (the connector should fit in easily when properly oriented), as shown below.

retaining screws

Caution

To avoid damaging the connector, take care not to bend

the pins when inserting the plug.

If the connector has retaining screws, tighten them by hand or with a screwdriver, depending on the screw type.

Setting Up Your System

1-5

Plug the monitor power cord into the monitor’s power inlet, as shown below.

Plug the other end of the power cord into an electrical outlet.

Setting Up, Your System

Using a Display Adapter Card

If you are using a non-VGA monitor, you’ll need to install a

display adapter (video) card in one of the computer’s option

slots before you can connect the monitor. (Your dealer may have already installed the video card for you.)

If the video card has not yet been installed, you’ll need to follow the instructions in Chapter 5 to install an option card. But first, check the following table to make sure your display adapter card and monitor are properly matched.

Monitor/video card compatibility

Monitor Monochrome

Color or EGA

EGA cards support only EGA monitors;

Video card

Monochrome display adapter (MDA) Multi-mode graphics adapter (MGA) Enhanced graphics adapter (EGA) Hercules@ graphics card

Color graphics adapter (CGA) Multi-mode graphics adapter (MGA) Enhanced graphics adapter (EGA);

When you are installing the video card, check to make sure any

switches or jumpers on the card are set properly. For example, you may need to change a switch setting to select color or monochrome. See the documentation that came with your

monitor or video card for instructions.

Setting Up Your System

1-7

Note

If you install a display adapter card, you must set jumper J3 on the main system board to disable the built-in VGA interface

so that your card can operate as the primary display adapter. You may also need to set jumper J5 to indicate whether a color or monochrome monitor is installed. See Chapter 5 for instructions on changing jumper settings.

Once you have installed your video card, return to this section to connect your monitor to the computer. If your monitor came with its own manual, follow the instructions there. Otherwise, you can follow the steps in “Using the VGA Interface” above; just insert your monitor connector into the video card port

instead of the built-in VGA port.

Connecting a Printer or Other Device

Your computer has both parallel and serial interfaces. TO

connect a printer or other peripheral device to one of these interfaces, follow the instructions below. Of course, Epson offers a full range of printers; ask your dealer for more information.

Using the Parallel Interface

The parallel interface on your computer is Centronic

compatible and uses a DB-25S connector. To connect your printer and computer, you need an IBM

compatible printer cable. If you are not sure which one you

need, check with your Epson dealer.

1-8

Setting Up Your System

Once you have the correct printer cable, follow these steps:

Place the printer next to the computer with the back panels

of both components facing you.

One end of the printer cable has a 25-pin, D-shell

connector. Position the plug to match the orientation of the parallel interface (marked with a special icon). Then insert the connector into the port, as shown below. If the plug has

retaining screws, tighten them by hand or with a screwdriver, depending on the screw type.

Setting Up Your System

l-9

Connect the other end of the cable to the printer, as shown below. To secure the cable, squeeze the clips at each side of the printer port and push them into place.

Plug the printer’s power cord into a three-prong, 120-volt,

grounded electrical outlet.

1-10

Setting Up Your System

Using the Serial Interface

If you have a printer, a modem, or other peripheral device with a serial interface, you can connect it to the serial (RS-232C) port on the back of the computer.

The serial port uses a DB-9P connector, so be sure you have a

compatible cable. To connect a serial device, follow the same steps as above for connecting a parallel device but insert the connector into the serial port, marked with a special icon, as shown below.

Note

You need to ensure that the serial port is set up so it functions

properly. If you are using the port for a serial printer, you need to redirect printer output to the serial port instead of the parallel port. To do this, you can use the MS-DOS MODE or SETMODE command or the MENU utility. See your MS-DOS Reference Manual for instructions.

Setting Up Your System

1-11

Connecting the Keyboard

Follow these steps to connect the keyboard:

Hold the keyboard cable connector so the indicator on the housing faces up. Insert the plug into the appropriate socket, marked with a keyboard icon, as shown below.

keyboard connector

Caution

Although the keyboard and mouse connectors are physically identical, they cannot be used interchangeably.

Be sure to insert the keyboard plug into the keyboard socket.

1-12 Setting Up Your System

You can raise the keyboard by adjusting the legs on the bottom. To change the angle of the keyboard, turn it over and flip each leg upward until it locks into place, as shown below.

Connecting the Mouse

Your computer has an auxiliary port for an IBM PS/2 compatible mouse that uses a miniature DIN (60pin) connector.

If you have purchased a mouse with this type of connector, you can connect it to the built-in port on your computer. If you have another kind of mouse that requires a different interface port,

you need to install the option card to provide the interface. To connect a mouse to the built-in mouse port, hold the mouse

plug so it is oriented properly with the computer socket. Insert the plug into the appropriate socket, marked with a mouse icon, as shown in the following illustration.
