Installation procedures

Page 6 Description

2 Installation procedures

2.1 System requirements

•Personal computer: The QUANCOM boards operate in

IBM-AT compatible computers with 80X86 or

compatible. (for example: 80386 / 80486 / Pentium )

•Bus: Your computer must have the corresponding bus.

(PCI / ISA)

You can find more information in chapter 4 “Technical hardware description”.

2.2 Safety precautions

For the sake of your security and the faultless function of your new QUANCOM board

mind the following advice:

•Before opening the computer please unplug it.

•Computer motherboards and components contain very delicate integrated circuit

(IC) chips. To protect them against damage from static electricity, you must follow

some precautions whenever you work on your computer. Use a grounded wrist

strap before handling computer components. If you don’t have one, touch both of

your hands to a safely grounded object or to a metal object, such as the power

supply case.

•Hold components by the edges and try not to touch the integrated circuit chips,

leads or circuitry.

•Place components on a grounded anti-static pad or on the bag that came with the

component whenever the components are separated from the system.

! ATTENTION ! Modifications, made to the device without explicit permission

from QUANCOM, lead to the loss of the operating permission

and the CE certificate.

Installation procedures

ISA-Extender Page 7

2.3 Installing the QUANCOM board

CAUTION:

1. Always turn the system power off and remove the power cord from the wall before

installing or removing any device.

2. Always pay regard to static electricity precautions.

See „Safety precautions“ in chapter 2.2

1. Switch off the computer and the connected devices and unplug them.

Warning: Static electricity can destroy your computer and the board!

Discharge yourself as described in chapter 3.2 “Safety precautions“.

2. To open your PC you have to detach the four

safety screws on the back of the case with a

screw driver. Then you can pull the cover

forwards. If necessary you must remove impeding

cables.

3. The slots are positioned at the back side of your

computer. The back wall of unused slots is

covered by a small metal plates. Search for a free

slot, detach its holding screw and remove the

small metal plate belonging to it.

4. Position the extension card into a free slot. Pay attention that the card is set firmly

in the slot.

5. Fasten the board with the screw of the small metal plate on the back wall.

3.1 General information

To slow down the time for comfortable testing of PC cards we developed the ISA-

Extender card. A master switch, on one side of the extender card, switches all ISA-

Bus signals and voltages. This is required to allow hotplugging of the tested ISA

cards, in other words, this method allows the unplugging and plugging of ISA cards

without rebooting the PC. All operating voltages are protected by easy exchangeable

fuses. The ISA-slot-connector can be configured with a DIP switch. With the DIP

switch you can select which type of signals will be passed through to the upper slot of

the ISA Extender. This feature will help you to find errors in cards that contain short

circuited data or address signals.

All operating voltages are available at the 9-pin D-Sub connector. The connector

allows the operation of external devices that need an additional power supply. All

standard ISA slot voltages are available at this connector.

To reset the ISA board under test condition, simply press the reset button on the ISA-

Extender board. This activates the ISA slot reset signal and resets the hardware on

your ISA card. Secondly, the reset signal is generated by turning the PC off and on.

The extender consists of 2 boards: The extender card and a small exchangeable and

separately deliverable board, which sole purpose is to contain the ISA slot and the

connector to the ISA-Extender. Because of the limited lifetime of the upper ISA slot

the replacement of this spare part is cheaper than to exchange the hole ISA-

Extender. This is an important feature in mass production and testing.

3.2 Other Products

A comparable card is available for an PCI-Bus. It supports the same functions. If you

Technical hardware description

Page 10 Description

3.3.2 The layout of the 9-pin D-Sub connector

The +5V operating voltage at the first pin, is not switched by the MOSFET and is

therefore available independently from the setting of the main and the DIP switch.

All the other operating voltages will be controlled by the setting on the DIP switch.

3.3.3 DIP switch settings

All switches switched to “OFF” is the default configuration for the ISA extender. If

SW1 is set to „OFF“ all the bus signals are passed through the upper ISA slot on top

of the extender. All operating voltages are switched by the MOSFETs to the slot on

top of the card if SW2 or SW3 are "OFF" and the master switch is switched on.

In some situations VCC and 5V are completely switched off but the voltages are

available at the upper slot. This is the result of a feedback through the signal lines.
