IEEE-488 Interface Board Installation for Quick Basic Program

This procedure works on an IBM PC (or compatible) running DOS or in a DOS window. This example uses

the National Instruments GPIB-PCII/IIA card.

1. Install GPIB-PCII/IIA card using National Instruments instructions.

2. Install NI-488.2 software (for DOS). Version 2.1.1 was used for the example.

3. Verify that config.sys contains the command: device = \gpib-pc\gpib.com

4. Reboot the computer.

5. Run IBTEST to test software configuration. Do not install the instrument before running IBTEST.

6. Run IBCONF to configure the GPIB – PCII/IIA board and dev 12. Set the EOS byte to 0AH and Enable

Repeat Addressing to Yes. See Figure 9-3. IBCONF modifies gpib.com.

7. Connect the instrument to the interface board and power up the instrument. Verify the address is 12 and

terminators are CR LF.

9.1.4.4

The IEEE-488 interface program in Table 9-3 works with QuickBasic 4.0/4.5 or Qbasic on an IBM PC (or

compatible) running DOS or in a DOS window. It assumes your IEEE-488 (GPIB) card is installed and

operating correctly (refer to Paragraph 9.1.4.3). Use the following procedure to develop the Serial Interface

Program in Quick Basic.

1. Copy c:\gpib-pc\Qbasic\qbib.obj to the QuickBasic directory (QB4).

2. Change to the QuickBasic directory and type: link /q qbib.obj,,,bqlb4x.lib; where x = 0 for QB4.0 and 5 for

QB4.5 This one-time only command produces the library file qbib.qlb. The procedure is found in the

National Instruments QuickBasic readme file Readme.qb.

3. Start QuickBasic. Type: qb /l qbib.qlb. Start QuickBasic in this way each time the IEEE interface is used to

link in the library file.

4. Create the IEEE example interface program in QuickBasic. Enter the program exactly as presented in

Table 9-3. Name the file "ieeeexam.bas" and save.

5. Run the program.

6. Type a command query as described in Paragraph 9.1.4.5.

7. Type "EXIT" to quit the program.
