Introduction

The IM-300 is an intelligent terminal developed for the POS environment.

The IM-300 has the following features.

1.An Intelâ Pentiumâ processor or Intel MMXä technology Pentium processor can be used. This high speed CPU processor provides the power and speed necessary for data processing.

2.Using it in combination with a variety of options and peripheral devices allows you to construct a system that suits your needs best.

3.The security on the front panel allows only the key owner to take out the floppy disk and the hard disk drive.

4.The keylock keys allow setting of the user's authority.

5.The refined power management function supplies power by the amount necessary for data processing, assuring optimum power saving.

6.Use of an updatable 256KB flash ROM for system ROM.

7.Use of PC/AT compatible BIOS. This allows you to execute not only specific application software but also any PC program of your choice.

8.Use of a built-in Device Diagnostics utility allows quick and easy error handling.

9.Support of Plug & Play function

10.Capability of supplying +5V or +12V to all serial ports.

11.Equipped with 32KB NVRAM for POS

12.Uses a PC-based open architecture to increase system expandability, providing one ISA slot, one PCI/ISA slot, and one special extension slot.

13.Input/output units include the keyboard unit, which allows free definition of key functions and the LCD unit. A touch-panel type of LCD unit is also

available, which allows you to do the free layout of the screen.

14.The built-in IBM PS/2 keyboard port supports IBM PC/AT compatible keyboards.Therefore, it is possible to connect any commercially

available keyboard in accordance with your environment.

15.Use of standard SIMMs allows you to install memory of up to 64MB.

16.Four serial ports and one parallel port allow connection of industrystandard peripheral devices, increasing system expandability.

17.In addition to the standard 3.5-inch floppy disk drive, up to two 2.5-inch hard disk drives can be installed.

Introduction 1

18.The hard disk drive can easily be removed or mounted. In the event of a system failure, the hard disk can be moved immediately to another IM300 to continue the processing.

19.Use of design consistent with EPSON POS system TM series printers. A TM printer can be mounted on the IM-300, so it does not occupy much space.

20.Connection of the dedicated MSR (magnetic stripe reader) unit (option) makes it possible to read magnetic cards.

21.Mounting of a battery unit (option) provides data backup function (Save To Disk Function) when the power is off accidentally.

22.Capability to mount user ROMs of up to 2MB.

4 Handling Precautions

Chapter 1

Setup

This chapter explains how to set up your hardware. For configuring your system using the BIOS Setup, see the next chapter.

Precautions on Setting up

This section describes items to observe when setting up the IM-300.

In addition to the above, there are warning instructions and cautions to observe at each work stage. They are given in each explanation.

Caution

∙Turn off the power of all equipment including the IM-300 and all the peripherals before setup. Be sure to turn off the side power switch for the IM-300 to turn it off.

When power is on, the IM-300 or peripherals units may be damaged during setup.

∙ Before setup, discharge static electricity on your body.

If you do not allow static electricity to discharge, trouble could result. Touch a grounded metal surface to allow static electricity to discharge.

∙ Do not touch the connectors.

Dirt may cause a malfunction.

screw

2.Remove the rear cover from the IM-300 by pulling the upper part of the rear cover backward then downward.

Setup 1-5

Setting Jumpers and DIP Switches

There are jumpers and DIP switches on the board of the IM-300. You can set them to control how the system operates.

There are two types of jumpers - the 2-pin jumper and 3-pin jumper.

			3		3
On	Off	1	1-2	1	2-3
2-pin jumper			3-pin jumper

For two-pin jumpers, the jumper is either on (it connects the two pins) or off (it doesn't connect the two pins).

For three-pin jumpers, the jumper setting is 1-2 when the jumper connects pins 1 and 2. The setting is 2-3 when pins 2 and 3 are connected. You see a 1 and a 3 printed on the circuit board to identify these pins. Also, one of the lines surrounding jumpers is thick, which indicates pin NO.1.

To move a jumper from one position to another, use needle-nose pliers or tweezers to pull it off the pins and move it to the desired position.

Caution

∙Be careful not to bend the jumper pins or damage any components on the board.

∙Do not change settings for jumpers and DIP switches not covered in this manual.

Installing a CPU

IM-300 contains a Socket 7, which can accept the following CPU types:.

∙Intel Pentium 100 MHz to 200 MHz

∙Intel MMX technology Pentium 166/200 MHz

Be sure to attach a CPU cooling fan to the CPU included in the package after you install the CPU. It prevents the CPU from overheating.

Caution

∙To avoid generating static electricity and damaging the CPU, ground yourself by touching a grounded metal surface before you touch the CPU.

∙Do not remove the rubber under the CPU cooling fan.

∙Do not touch the pins of the CPU.

Dirt may cause a malfunction.

Follow these steps to install the CPU:

1.Confirm that the DIP switches are correctly set for the CPU you are going to install.

2.Lift the release lever of the Socket 7.

3.Align the pins of the CPU to the pin holes of the Socket 7. Be sure to pay attention to the direction of the CPU.

lever

4.Push down the CPU into the Socket 7.

5.Push down the release lever and lock it.

1-12 Setup

6.Hook the hole in EIF clip for the CPU cooling fan onto the notch on the Socket 7.

7.Place the CPU cooling fan on the CPU surface.

Heat radiation plate

8.Push down the opposite side of the EIF clip and hook it.

9.Slide the head of the clip to left and lock it.

10.Connect the cooling fan cable to the socket as shown below. Be careful not to place the cable on the CPU cooling fan.

Removing a CPU:

Caution

Before removing the CPU, turn off the IM-300 power; then wait for about 20 minutes until the heat radiation plate of the cooling fan and the CPU cool down.

The CPU and the heat radiation plate are hot. They may cause burns.

To remove the CPU, reverse the installation steps.
