IBM PC/XT/AT or PS/2 with
IOtech Driver488 Software
F.6 Introduction
Driver488 software is an IEEE-488 driver for IBM PC and
compatible computers. When combined with an IEEE-488
interface board, the package can control devices from
languages including BASIC, Pascal, Fortran, and C.
Driver488 software is compatible with:
• IOtech GP488B or GP488/2 boards
• National Instruments GPIB-PC, PCII, PCIIA, or PCIII
boards
• Capital Equipment #01000-00300 board
• IBM GPIB Adapter
The following GW-BASIC program sends a command mes-
sage to the Model 2001 and displays the instrument response

for queries on the CRT. The computer must be equipped with
an IEEE-488 interface board, the DOS 3.00 (or later) operat-
ing system, and a language with DOS I/O capability.
Driver488 controller software must be installed and config-
ured as described in the instruction manual.
F.7 Directions
1. Using the front panel MENU key and the GPIB menu
item, set the primary address of the Model 2001 to 16.
2. With power off, connect the Model 2001 to the IEEE-
488 interface installed in the IBM computer.
3. Type in GWBASIC on the computer and get into the Mi-
crosoft interpretive BASIC language.
4. Enter the lines below using the return key after each
line.
5. Run the program and type in the desired command
string at the Enter Program Message prompt. For exam-
ple, to request a reading, type in :FETCh? and press the
RETURN key. The reading will be displayed on the
CRT.
