• Check the GPIB-PCII/IIA interface board to ensure that it is not connected to a GPIB cable. WIBTEST may not function properly if a cable is connected to the GPIB-PCII/IIA.

After you complete this checklist, run WIBTEST again. If WIBTEST still fails, complete the GPIB-PCII/IIA Hardware and Software Configuration Form in Appendix E, Customer Communication, and contact National Instruments for technical support.

If no errors occur, the NI-488.2 handler for Windows is installed correctly and you are ready to start using your GPIB-PCII/IIA with your graphics application program.

If your graphics application program instructs you to change the default settings of the software handler, refer to Appendix B, Changing Board and Device Characteristics, for more information on how to run the configuration program and on the configurable software parameters and their default values.

Appendix B Changing Board and Device Characteristics

This appendix contains instructions for changing the default board and device characteristics of the NI-488.2 handler for MS-DOS/Windows.

Note: Most graphics application software is written to use the default

configuration of the NI-488.2 handler. Do not change the default parameters of the NI-488.2 handler unless your graphics application manual instructs you to do so.

Board and Device Characteristics

Two groups of features can be changed in the handler file or configuration file. The first group consists of the characteristics of the devices attached to your GPIBPCII/IIA. The second group consists of the characteristics of each GPIB-PCII/IIA installed in the computer. The following sections describe the characteristics of each group.

Characteristics of the Graphics Devices

Each device used with the GPIB-PCII/IIA has the following characteristics:

• A symbolic name of each device on the GPIB (such as DEV5 or SCANNER).

• A primary and, if used, a secondary address for each device.

• A time limit imposed when executing certain functions. This time limit ensures that transfers do not hang up the GPIB indefinitely.

• A way to terminate I/O transmissions to and from the device. Some devices require or append an end of string (EOS) character, such as the ASCII line feed character, to data strings. Others use the GPIB END message, which is sent or received via the EOI signal line. Still others use both. Some terminate I/O only when a predetermined number of bytes are sent or received.

Changing Board and Device Characteristics Appendix B

Characteristics of Each GPIB-PCII/IIA

Each GPIB-PCII/IIA board has the following characteristics:

• A symbolic name (either GPIB0 or GPIB1).

• A GPIB primary or secondary address.

• A computer I/O address.

• A GPIB-PC mode (either PCII or PCIIA).

• The capability to be designated as the System Controller of the devices on its bus.

• A time limit imposed when executing certain functions.

• A way to terminate I/O transmissions to and from the board when executing board calls—for example, by an EOS character, an END message, and/or a byte count.

• An interrupt line that the board uses, if any.

• A DMA channel that the board uses, if any.

• High-speed, highest-speed, or normal timing when transmitting data to a device. With normal timing, there is a delay of at least 2 µs after the data is placed on the GPIB before the Data Valid (DAV) line is asserted. With highspeed timing, this delay is decreased to about 500 ns, and with highest-speed timing, it is decreased to about 350 ns. The default setting of 2 µs is recommended, as some devices cannot communicate at higher speeds.

Default Configurations

The default configurations of the software were set at the factory. For example, the default device names of the 32 GPIB devices are DEV1 through DEV32, but your application manual may instruct you to assign a more descriptive name to a particular device, such as SCANNER.

GPIB-PCII/IIA for Graphics B-2 © National Instruments Corp.

Appendix B Changing Board and Device Characteristics

Note: Do not give a GPIB device the same name as a directory or file on your

disk drive.

You can also use the configuration programs, IBCONF or WIBCONF, to examine the current default settings in the handler file.

If you do not make changes to the configuration, the default characteristics of the software remain in effect.

Primary Default Characteristics

The following are the primary default characteristics of the handler:

• The GPIB-PC mode is assumed to be the default setting. See Appendix C, Hardware and Software Configuration, for more information on the GPIB-PC mode.

• There are 32 active devices with symbolic names DEV1 through DEV32.

• GPIB addresses of these devices are the same as the device number. For example, DEV1 is at address 1.

• The first 16 devices are assigned to GPIB0 as their access board, and the second 16 devices are assigned to GPIB1 as their access board. GPIB0 is the symbolic name of the first GPIB-PCII/IIA board in your system. If you have an additional GPIB-PCII/IIA board in your system, its symbolic name is GPIB1.

• Each GPIB-PCII/IIA is System Controller of its independent bus and has a GPIB address of 0.

• The END message is sent with the last byte of each data message to a device. Each data message that is read from a device automatically terminates when END is received. No EOS character is recognized.

• The time limit on I/O and wait function calls is approximately 10 seconds.

• GPIB0 is a GPIB-PCII board at base I/O address 02B8 hex using DMA channel 1 and no interrupt line, or GPIB0 is a GPIB-PCIIA board at base I/O address 02E1 hex using DMA channel 1 and no interrupt line.

Changing Board and Device Characteristics Appendix B

Repeat Addressing (Device Characteristic Only)

Normally, the GPIB address of a device is issued before each device function pertaining to that device. If you enter yes for the Repeat Addressing field, this addressing occurs even if the device is already properly addressed. The default option for this characteristic is no.

Hardware and Software Configuration Appendix C

Check Tables C-1 and C-2 to make sure that the factory default settings of your GPIB-PCII/IIA board are the same as the values you entered when prompted by the IBDIAG program. If they are not, run IBDIAG again, and enter the default values when prompted. For instructions on running IBDIAG again, refer to Appendix D, Interactive Software Installation.

If IBDIAG still returns an error message, one of the switches and jumpers on your GPIB-PCII/IIA board may be configured to the same setting as another board or device in your computer. Check the manuals of any other devices or boards you are using to determine if they conflict with the configuration settings of your GPIB-PCII/IIA board. If the manuals are not available, check Tables C3, C-4, and C-5 later in this appendix for possible conflicts.

If there is a conflict, you need to change the conflicting setting on either your GPIB-PCII/IIA board or the other board or device and run IBDIAG again. To change a hardware configuration setting on your GPIB-PCII/IIA board, follow the instructions in the following section, Changing Hardware Configuration

Settings.

If you complete these instructions and IBDIAG still returns an error message, complete the GPIB-PCII/IIA Hardware and Software Configuration Form in Appendix E, Customer Communication, and contact National Instruments for technical support.

Changing Hardware Configuration Settings

Complete the following steps to change the configuration settings of your GPIBPCII/IIA interface board.

Step 1. Configure the Hardware

Base I/O Address Selection

GPIB-PCII mode and GPIB-PCIIA mode use different regions of I/O address space. By default, GPIB-PCII mode uses base I/O address 2B8 hex and GPIBPCIIA mode uses base I/O address 2E1 hex. To select a different base I/O address for your GPIB-PCII/IIA, follow the instructions that pertain to the GPIB-PC mode setting of your board.

GPIB-PCII/IIA for Graphics C-4 © National Instruments Corp.

Appendix C Hardware and Software Configuration

GPIB-PCII Mode

Switch block U2 is used to set the address for address lines A3 through A9. The addresses are in a consecutive block of eight beginning on any multiple of 8 between 100 and 3F8 hex. For example, for the default address, 2B8 hex, the GPIB-PCII uses the address space 2B8 through 2BF hex.

Press the side marked 1 to select a binary value of 1 for the corresponding address bit. Press the 0 side of the switch to select a value of 0 for the corresponding address bit.

To change the base I/O address, press each switch to the desired position, then check each switch to make sure it is pressed down all the way.

Figure C-3 shows two possible switch settings. Each of the address selections shows how the base I/O address was calculated from the switch positions.

Appendix C Hardware and Software Configuration

To change the base I/O address, locate the switches at U2, press each switch to the desired position, and check each switch to make sure it is pressed down all the way.

If you change the base I/O address setting from the default setting, record the new setting on the GPIB-PCII/IIA Hardware and Software Configuration Form in Appendix E, Customer Communication. Remember that you must run the IBDIAG diagnostic program and configure the software, as explained later in this appendix, after you change any hardware configuration settings.

Possible Conflicts

Table C-3 lists some of the I/O addresses used by other PC plug-in interface boards and adapters. This is not a complete list, but it may help in determining possible address conflicts. Symptoms of I/O address conflicts vary widely. At one extreme, conflicts can prevent the computer from booting. At the other extreme, they can cause problems that do not surface until a considerable amount of time has elapsed. When conflicts do surface, the problems can exhibit themselves simply as strange behavior.

National Instruments has made every effort to select a default base I/O address that will work. However, because of the numerous different interface boards available for use in the PC, it is not possible to select a base I/O address that is guaranteed to work in all systems.

Note: In GPIB-PCII mode, eight consecutive addresses are used, while in

GPIB-PCIIA mode, sixteen addresses spread throughout the upper address space are used.

Interrupt Selection

The GPIB-PCII/IIA interface board can use any of six interrupt lines available on the PC, or no interrupts at all. The interrupt line is selected using the jumper sets labeled IRQ2 through IRQ7 (see Figure C-1). The GPIB-PCII/IIA is set at the factory to use line 7. To select another interrupt line, place the supplied jumper across the two pins adjacent to the label designating that interrupt line. Figure C-5 shows the selection of interrupt line 7.

Figure C-5. Default Interrupt Jumper Setting for GPIB-PCII Mode

If you do not want to use interrupts, you must logically disconnect the GPIBPCII/IIA from the IRQ lines by selecting NONE for the interrupt line when you run the software configuration program, as explained in Step 3. Configure the Software, later in this appendix. The board can remain in the backplane and no jumpers have to be moved or changed.

Shared Interrupts in GPIB-PCIIA Mode

Multiple GPIB-PCII/IIA boards can share the same interrupt level if they are all configured for GPIB-PCIIA mode.

If you use the GPIB-PCII/IIA in GPIB-PCIIA mode and you want to change the interrupt line, you must set switches I0, I1, and I2 in switch block U2 to the line setting in addition to setting the interrupt jumpers.

DMA Channel Selection

The GPIB-PCII/IIA can use DMA channels 1, 2, or 3, or no DMA at all. The DMA channel is selected by the jumper sets labeled DRQ1 through DACK 3 (see Figure C-1).

Each DMA channel consists of two signal lines, as shown in Table C-5.

Hardware and Software Configuration Appendix C

Table C-5. DMA Channels for the GPIB-PCII/IIA

Signal Lines

DMA

Channel

You must position two jumpers to select a DMA channel. One jumper selects the DMA Request line, and the other selects the DMA Acknowledge line. You must move these two jumpers as a pair, and the DMA Acknowledge and DMA Request lines that you select must have the same numeric suffix for proper operation.

Figure C-8 shows the jumper position for the default DMA channel setting, DMA channel 1.

If you do not want to use DMA for GPIB transfers (the GPIB-PCII/IIA alternatively can use programmed I/O transfers), you must logically disconnect the GPIB-PCII/IIA from the DMA lines by selecting NONE for the DMA line when you run the software configuration program, as explained in Step 3. Configure the Software, later in this appendix. The board can remain in the back panel and no jumpers have to be moved or changed.

Appendix C Hardware and Software Configuration

Note: Disabling DMA will decrease performance substantially.

If you change the DMA jumper setting from the default setting, record the new setting on the GPIB-PCII/IIA Hardware and Software Configuration Form in Appendix E, Customer Communication. Remember that you must run the IBDIAG diagnostic program and configure the software, as explained later in this appendix, after you change any hardware configuration settings.

Possible Conflicts

There are only three DMA channels that can be used by the GPIB-PCII/IIA interface board. If any device uses DMA channel 1, change the DMA channel used by either the GPIB-PCII/IIA or the other device to DMA channel 2 or 3. If no DMA channel is available, configure the software to run without DMA using the software configuration program.

Shield Ground Configuration

The GPIB-PCII/IIA is set at the factory with the jumper in place to connect the logic ground of the GPIB-PCII/IIA to its shield ground. This configuration minimizes the EMI emissions.

Caution: The GPIB-PCII/IIA was tested for compliance with FCC

standards with the shield ground connected to logic ground. Removing the jumper might cause EMI emissions to exceed any or all of the applicable standards.

If your application requires that logic ground be disconnected from shield ground, refer to Figure C-1 to locate the shield ground jumper W1 on the GPIBPCII/IIA. Remove the jumper and place it across only one of the jumper pins, as shown in Figure C-9.

Step 2. Run the IBDIAG Diagnostic Program

If you have changed any hardware configuration settings, you must run the diagnostic program, IBDIAG, again. For instructions on running IBDIAG, refer to Appendix C, Interactive Software Installation.

Step 3. Configure the Software

If you have changed any hardware configuration settings, you must make appropriate changes to the NI-488.2 handler. To do so, you must run the configuration program, IBCONF or WIBCONF, and edit the board parameters (such as the base I/O address or interrupt line) that you have changed.

If you are using the NI-488.2 software for Windows, skip to Configuring the Software for Windows, later in this appendix. If you are using the NI-488.2 software for MS-DOS, proceed to the next section, Configuring the Software for

MS-DOS.

Appendix C Hardware and Software Configuration

Configuring the Software for MS-DOS

Use the software configuration program, IBCONF, to change or examine the configuration parameters of the NI-488.2 software handler file, GPIB.COM.

Perform the following steps to change a software parameter to match changes to the hardware configuration.

1. Run IBCONF by entering the following commands:

cd \gpib-pc ibconf

2. Press any key to display the configuration map.

3. When the configuration map appears, make sure that GPIB0 is highlighted and press <F8> to edit the board configurations.

4. Using the arrow keys, move the highlight to the board parameter you want to change.

5. Use the arrow keys to change the value of the parameter to match the hardware configuration.

6. Press <F9> to stop editing.

7. Press <F9> once again to quit IBCONF.

8. IBCONF displays a prompt asking if you want to save your changes. Enter y for yes.

9. IBCONF displays a prompt asking if you want to update the handler in memory. Enter y for yes. In some cases, IBCONF instructs you to restart your computer.

Changes to other configurable parameters can be made in the same manner.

Hardware and Software Configuration Appendix C

Configuring the Software for Windows

Use the software configuration program, WIBCONF, to change or examine the configuration parameters of the NI-488.2 software handler. WIBCONF is not a Windows application. You can run it to configure the software directly from Windows.

WIBCONF operates in much the same way as the NI-488.2 MS-DOS configuration program, IBCONF. However, the following differences exist between IBCONF for MS-DOS and WIBCONF for Windows:

• Instead of configuring the handler file, GPIB.COM, WIBCONF actually modifies the configuration file, GPIB.INI.

• Auto-configuration for NI-488.2 GPIB DLLs is not supported.

• The option of configuring the loaded driver does not apply.

Perform the following steps to change a software parameter to match changes to the hardware configuration.

1. Select the WIBCONF icon by double-clicking on it.

2. WIBCONF displays a prompt asking for parameters. If you used the quick version of INSTALL, press <Enter>.

If you used the interactive version of INSTALL and did not install the software in the default directory, C:\WINDOWS, enter the name of your Windows directory, such as E:\WINDOWS\GPIB.INI, for example.

3. Press any key to display the configuration map.

4. When the configuration map appears, make sure that GPIB0 is highlighted and press <F8> to edit the board configurations.

5. Using the arrow keys, move the highlight to the board parameter you want to change.

6. Use the arrow keys to change the value of the parameter to match the hardware configuration.

Appendix C Hardware and Software Configuration

7. Press <F9> to stop editing.

8. Press <F9> once again to quit WIBCONF.

9. WIBCONF displays a prompt asking if you want to save your changes. Enter y for yes.

Changes to other configurable parameters can be made in the same manner.

Appendix D Interactive Software Installation

This appendix contains instructions for running the interactive version of INSTALL.

By using he interactive version of INSTALL, you can change the default filenames and directories used in installation. Enter the following command to run INSTALL:

:install

where x is the letter of the drive containing the distribution diskette.

INSTALL displays a main menu with three options: DOS GPIB Installation, Windows GPIB Installation, and Return to DOS.

If you are using the NI-488.2 software for Windows, skip to INSTALL for Windows, later in this appendix. If you are using the NI-488.2 software for MS-DOS, proceed to the following section, INSTALL for MS-DOS.

INSTALL for MS-DOS

Select DOS GPIB Installation from the main menu. INSTALL displays a DOS installation menu with three options: GPIB

Installation, Diagnostics, and Return to DOS.

IBDIAG again, skip to Running IBDIAG for MS-DOS, later in this section.

Interactive Software Installation Appendix D

Installing the Software for MS-DOS

Select GPIB Installation to install the NI-488.2 software files. INSTALL displays a screen asking you to confirm or change the default

installation settings, the destination directory and the boot drive.

• The destination directory setting is the drive and directory name of the location to which INSTALL will copy the NI-488.2 software. The default value of this setting is c:\gpib-pc. In most cases, the drive name given in this field should be the drive off of which you start your computer.

• The boot drive setting is the drive name of the disk (hard disk or diskette) off of which you start your computer. If you start from a diskette, this field typically contains A: or B:. If you start from a hard disk, this field typically contains C:. The default value of this setting is C:.

To change these settings, use the arrow keys to move the highlight to the appropriate field and enter the new value. Press <Enter> to exit the menu.

INSTALL then checks the information you entered. If there is a problem accessing any of the specified drives, it displays an error message and prompts you to re-enter the offending setting. If there are no errors, INSTALL installs the software files.

Note: Press <Esc> at any time to abort the installation.

When the installation is complete, INSTALL asks to modify your CONFIG.SYS file. If you enter yes, INSTALL adds the following line to your CONFIG.SYS file:

device=

where the NI-488 software installed on your computer, INSTALL replaces the old version's information in CONFIG.SYS with the new information.

If you enter no to the above prompt, INSTALL displays a message informing you of the correct line that you should add to your CONFIG.SYS file.
