Personal488 User's Manual For Windows 95 and Windows NT Personal488/PCI (with PCI488) 3

Installing the New Hardware & Hardware Drivers

Typical IEEE 488 interface boards are installed into expansion slots inside the PC's system unit.
Typical PCs have the following types of expansion slots

• ISA expansion slots. ISA slots can either be an 8-bit slot with one card-edge receptacle (PC-bus

compatible), or a 16-bit slot with two card-edge receptacles (AT-bus compatible). Eight-bit ISA
boards may be used in either the 8-bit or 16-bit ISA slot, while 16-bit ISA boards may only be
used in the 16-bit ISA slot.

• PCI expansion slots. PCI slots are 32-bit slots, used only by PCI boards.
For technical assistance, see chapter Troubleshooting on page 119 in this manual, or the

troubleshooting section in your PC’s manual. If you are still not sure of the problem, contact the dealer
or manufacturer of your interface board or PC.

Step 1: Installing the PCI488 Interface Board into a PCI Slot

General instructions for installing the board are given since the design of computer cases varies. Refer
to your PC's reference manual whenever in doubt.

1. Turn OFF the power to your computer and any other connected peripheral devices. Follow the
precautions for static electricity discharge.

• Touch a large grounded metal surface to discharge any static electricity build up in your body.

• Avoid any contact with internal parts. Handle cards only by their edges.

• Disconnect the AC power before removing the cover.

2. Unplug all power cords and cables that may interfere from the back of the computer.

3. Remove your computer's cover by removing its mounting screws with a screwdriver. Slide the
cover OFF. If necessary, refer to your PC's manual.

4. Your IEEE 488 controller interface must be installed in a 32-bit PCI-bus expansion slot. Select an
available PCI expansion slot and remove its slot cover by unscrewing the holding screw and sliding
it out. Save this screw for securing the interface after it is installed.

5. To install the IEEE 488 controller interface, carefully align the card edge connector with the PCI
slot on the motherboard, fitting the IEEE 488 port through the rear panel opening. Push the board
down firmly, but gently, until it is well seated.

4 Personal488/PCI (with PCI488) Personal488 User's Manual For Windows95 and Windows NT

6. Replace the cover slot holding screw to secure the board in place.

7. Replace the computer's cover and screws. Then reconnect all power cords and cables to the back of
the computer. If available, connect your external data acquisition instrument to the IEEE 488 port
connector on the interface.

8. Turn on your PC.

At this point, the hardware installation is complete. Continue to Step 2.

Step 2: Detecting the PCI488 Interface Board in "Add New Hardware"

1. After installing the IEEE 488 controller interface, turn on your computer. Windows will detect the
new hardware and prompt for a Manufacturer’s Disk.

2. Insert the disk labeled "Driver488 Driver Disk, 1 of 1" into the floppy disk drive. Click OK.

3. The hardware will now be recognized and configured by Windows; the "Add New Hardware
Wizard" will auto-assign an available I/O base address, IRQ (Interrupt), and DMA channel.
(Additional PCI488 interfaces may share the same IRQ and DMA values.)

Continue as prompted to load the interface driver, but DO NOT restart Windows. Select No to
NOT shut down and go directly to the Device Manager to verify the presence of the new hardware
device.

At this point, the hardware detection is complete. Continue to Step 3.

Step 3: Verifying the PCI488 Interface Installation & Driver488 Software Settings

1. To confirm proper installation, open the Control Panel window from the Start > Settings menu,
click on the System icon, and select the Device Manager tab. Look for a device type named
"IEEE488.2 Controllers" and below it, verify the presence of the new hardware device.

2. During Driver488 installation, a new Control Panel applet titled "IEEE 488" was installed under the
Control Panel with default settings selected.

To verify or configure the Driver488 software settings for your IEEE 488 interface(s) and IEEE 488
external device(s), see chapter Driver488/W95 & Driver488/WNT on page 41.

3. Restart Windows and once again verify the hardware installation and Driver488 configuration in
Device Manager.

At this point, the hardware and driver verification is complete. Continue to Step 4.

Step 4: Installing the PCI488 Interface Software Support Files

1. Insert the disk titled "IEEE 488 Software Installation Disk, 1 of 2" into the floppy disk drive.

2. To install, you can do one of the following:

• Select Run from the Start Menu, type in A:\SETUP.EXE, then click OK.

• Go to My Computer or Windows Explorer, double-click on the Floppy Drive icon, then double-

click on the Setup icon.

• Or go to the Control Panel from the Start > Settings menu, double-click on the Add/Remove

Programs icon, then click the Install button.

3. The Installation program will step you through various options on installing these software support
files.

Note: These files are NOT required to get the hardware to work properly, but it is recommended

if any software development is desired or Help files are needed.

4. Any or all of the installed software support files may be removed by going to the Control Panel
from the Start > Settings menu, double-clicking on the Add/Remove Programs icon, then selecting
"Personal IEEE 488 v 2.0", and clicking the Add/Remove… button.

At this point, the installation of software support files is complete.

Configuring the New Hardware

The following text will guide you through the setup of your IEEE 488 controller interface. It includes
instructions on how to verify the resource settings of ports in your system, and how to properly
configure the switches/jumpers on your interface board.

To avoid a configuration conflict, you must first verify which I/O addresses, IRQs, and DMAs are
being used by existing ports in your system, prior to configuring and installing the IEEE 488 controller
interface.

Step 1: Verifying/Recording the Current System Settings

The Windows Control Panel enables you to easily determine and configure the I/O addresses, IRQ
setting, and DMA settings in your system for proper operation. Perform the following steps to verify
your system settings.

1. Open the Control Panel window from the Start > Settings menu, click on the System icon, and
select the Device Manager tab. Under the line "Ports (COM & LPT)", look for a list of used ports.
For each port, highlight the port and click on the Properties button.

2. Properties already being used in the system are displayed under the Resources tab. Values NOT
listed are available.

• For each listed port, record which Input/Output (I/O) address, if any, is being used.

• For each listed port, record which Interrupt Request (IRQ) value, if any, is being used.

• For each listed port, record which Direct Memory Access (DMA) value, if any, is being used.

3. Exit Windows and turn the system OFF.

The I/O base address, IRQ, and DMA settings are switch/jumper selectable via the following locations
on the AT488 interface board: One 2-microswitch DIP switch labelled S1, one 4-microswitch DIP
switch labelled S2, two 14-pin headers labelled DACK and DRQ, and one 22-pin header labelled IRQ.
The DIP switch settings, and the arrangement of the jumpers on the headers set the hardware
configuration.

For the next steps, make sure that the I/O address, IRQ, and DMA, set on the interface board are
different from any existing ports in your system. A conflict results when two I/O addresses, IRQs, or
DMAs are the same. (As the exception, additional AT488 interfaces may share the same IRQ and DMA
values.) If there is a conflict, perform the following steps to select new switch/jumper settings.

16 Personal488/AT (with AT488) Personal488 User's Manual For Windows95 and Windows NT

Step 2: Configuring the AT488 Interface I/O Base Address

1. The factory default I/O base address is 02E1. If this creates a conflict, reset switch S1 according to
the figure and following table. The register addresses will be automatically relocated at fixed
offsets from the base address.

2. If reset, record the new Input/Output (I/O) address being used.

Selected I/O Base Address Register

02E1 22E1 42E1 62E1

Automatic Offset Addresses Read Register Write Register

02E1 22E1 42E1 62E1 Data In Data Out
06E1 26E1 46E1 66E1 Interrupt Status 1 Interrupt Mask 1
0AE1 2AE1 4AE1 6AE1 Interrupt Status 2 Interrupt Mask 2
0EE1 2EE1 4EE1 6EE1 Serial Poll Status Serial Poll Mode
12E1 32E1 52E1 72E1 Address Status Address Mode
16E1 36E1 56E1 76E1 CMD Pass Through Auxiliary Mode
1AE1 3AE1 5AE1 7AE1 Address 0 Address 0/1
1EE1 3EE1 5EE1 7EE1 Address 1 End of String

The I/O base address sets the addresses used by the computer to communicate with the IEEE 488
interface hardware on the board. The address is normally specified in hexadecimal and can be 02E1,

22E1, 42E1, or 62E1. The registers of the IOT7210 IEEE 488 controller chip and other auxiliary

registers are then located at fixed offsets from the base address.
Most versions of Driver488 are capable of managing as many as four IEEE 488 interfaces. To do so,

the interface configurations must be arranged to avoid conflict among themselves. No two boards may
have the same I/O address; but they may, and usually should, have the same DMA channel and
interrupt level.

Personal488 User's Manual For Windows 95 and Windows NT Personal488/AT (with AT488) 17

Step 3: Configuring the AT488 Interface Interrupt (IRQ)

1. The factory default Interrupt (IRQ) is 7. If this creates a conflict, reset switch S2 and jumper IRQ
according to the figure. The switch and jumper settings must both indicate the same interrupt level
for correct operation with interrupts.

2. If reset, record the new Interrupt (IRQ) being used.

The AT488 interface board may be set to interrupt the PC on the occurrence of certain hardware
conditions. The main board interrupt may be set to IRQ level 3 through 7, 9 through 12, 14, or 15.
Interrupts 10 through 15 are only available in a 16-bit slot on an AT-class machine. Interrupt 9
becomes synonymous with Interrupt 2 when used in a PC/XT bus.

The selected interrupt may be shared among several AT488s in the same PC/AT chassis. The AT488
adheres to the “AT-style” interrupt sharing conventions. When the AT488 requires service, the IRQ
jumper determines which PC interrupt level is triggered. When an interrupt occurs, the interrupting
device must be reset by writing to an I/O address which is different for each interrupt level. The switch
settings determine the I/O address to which the board’s interrupt rearm circuitry responds.

18 Personal488/AT (with AT488) Personal488 User's Manual For Windows95 and Windows NT

Step 4: Configuring the AT488 Interface DMA Channel

1. The factory default DMA channel is 5. If this creates a conflict, reset jumpers DACK and DRQ
according to the figure. Both the DRQ and DACK jumpers must be set to the desired DMA channel
for proper operation.

2. If reset, record the new DMA channel being used.

Direct Memory Access (DMA) is a high-speed method of transferring data from or to a peripheral, such
as a digitizing oscilloscope, to or from the PC’s memory. The AT class machine has seven DMA
channels. Channels 0 to 3 (8-bit), 5, 6, and 7 (16-bit) are available only in a 16-bit slot on a PC/AT­class machine. Channel 2 is usually used by the floppy disk controller, and is unavailable. Channel 3
is often used by the hard disk controller in PCs, XTs, and the PS/2 with the ISA bus, but is usually not
used in ATs. Channels 5 to 7 are 16-bit DMA channels and offer the highest throughput (up to 1
Megabyte per second). Channels 0 to 3 are 8-bit DMA channels and although slower, they offer
compatibility with existing GP488B applications that only made use of 8-bit DMA channels. Under
some rare conditions, it is possible for high-speed transfers on DMA Channel 1 to demand so much of
the available bus bandwidth that simultaneous access of a floppy controller will be starved for data due
to the relative priorities of the two channels.

Personal488 User's Manual For Windows 95 and Windows NT Personal488/AT (with AT488) 19

Installing the New Hardware & Hardware Drivers

Typical IEEE 488 interface boards are installed into expansion slots inside the PC's system unit.
Typical PCs have the following types of expansion slots

• ISA expansion slots. ISA slots can either be an 8-bit slot with one card-edge receptacle (PC-bus

compatible), or a 16-bit slot with two card-edge receptacles (AT-bus compatible). Eight-bit ISA
boards may be used in either the 8-bit or 16-bit ISA slot, while 16-bit ISA boards may only be
used in the 16-bit ISA slot.

• PCI expansion slots. PCI slots are 32-bit slots, used only by PCI boards.
For technical assistance, see chapter Troubleshooting on page 119 in this manual, or the

troubleshooting section in your PC’s manual. If you are still not sure of the problem, contact the dealer
or manufacturer of your interface board or PC.

Step 1: Installing the AT488 Interface Board into an ISA Slot

General instructions for installing the board are given since the design of computer cases varies. Refer
to your PC's reference manual whenever in doubt.

1. Turn OFF the power to your computer and any other connected peripheral devices. Follow the
precautions for static electricity discharge.

• Touch a large grounded metal surface to discharge any static electricity build up in your body.

• Avoid any contact with internal parts. Handle cards only by their edges.

• Disconnect the AC power before removing the cover.

2. Unplug all power cords and cables that may interfere from the back of the computer.

3. Remove your computer's cover by removing its mounting screws with a screwdriver. Slide the
cover OFF. If necessary, refer to your PC's manual.

4. Your IEEE 488 controller interface must be installed in a 16-bit ISA-bus expansion slot. Select an
available ISA expansion slot and remove its slot cover by unscrewing the holding screw and sliding
it out. Save this screw for securing the interface after it is installed.

5. To install the IEEE 488 controller interface, carefully align the card edge connector with the ISA
slot on the motherboard, fitting the IEEE 488 port through the rear panel opening. Push the board
down firmly, but gently, until it is well seated.

6. Replace the cover slot holding screw to secure the board in place.

7. Replace the computer's cover and screws. Then reconnect all power cords and cables to the back of
the computer. If available, connect your external data acquisition instrument to the IEEE 488 port
connector on the interface.

8. Turn on your PC.

At this point, the hardware installation is complete. Continue to Step 2.

Step 2: Detecting the AT488 Interface Board in "Add New Hardware"

1. After installing the IEEE 488 controller interface, turn on your computer. Windows will detect the
new hardware and prompt for a Manufacturer’s Disk.

2. Insert the disk labeled "Driver488 Driver Disk, 1 of 1" into the floppy disk drive. Click OK.

3. The hardware will now be recognized by Windows; the "Add New Hardware Wizard" will assign
the available I/O base address, IRQ (Interrupt), and DMA channel, which were configured earlier.
(Additional AT488 interfaces may use the same IRQ and DMA values.)

Continue as prompted to load the interface driver, but DO NOT restart Windows. Select No to
NOT shut down and go directly to the Device Manager to verify the presence of the new hardware
device.

At this point, the hardware detection is complete. Continue to Step 3.

Configuring the New Hardware

The following text will guide you through the setup of your IEEE 488 controller interface. It includes
instructions on how to verify the resource settings of ports in your system, and how to properly
configure the switches/jumpers on your interface board.

To avoid a configuration conflict, you must first verify which I/O addresses, IRQs, and DMAs are
being used by existing ports in your system, prior to configuring and installing the IEEE 488 controller
interface.

Step 1: Verifying/Recording the Current System Settings

The Windows Control Panel enables you to easily determine and configure the I/O addresses, IRQ
setting, and DMA settings in your system for proper operation. Perform the following steps to verify
your system settings.

1. Open the Control Panel window from the Start > Settings menu, click on the System icon, and
select the Device Manager tab. Under the line "Ports (COM & LPT)", look for a list of used ports.
For each port, highlight the port and click on the Properties button.

2. Properties already being used in the system are displayed under the Resources tab. Values NOT
listed are available.

• For each listed port, record which Input/Output (I/O) address, if any, is being used.

• For each listed port, record which Interrupt Request (IRQ) value, if any, is being used.

• For each listed port, record which Direct Memory Access (DMA) value, if any, is being used.

3. Exit Windows and turn the system OFF.

The I/O base address, IRQ, and DMA settings are switch/jumper selectable via the following locations
on the GP488B interface board: One 8-microswitch DIP switch labelled SW1, two 12-pin headers
labelled J3 and J4, and one 3-pin header labelled J5. The DIP switch settings, and the arrangement of
the jumpers on the headers set the hardware configuration.

For the next steps, make sure that the I/O address, IRQ, and DMA, set on the interface board are
different from any existing ports in your system. A conflict results when two I/O addresses, IRQs, or
DMAs are the same. (As the exception, additional GP488B interfaces may share the same IRQ and
DMA values.) If there is a conflict, perform the following steps to select new switch/jumper settings.
