IBM PC, Microsoft C V5.1 using the National Instruments GPIB interface.
To successfully interface the SR430 to a PC via the GPIB interface, the instrument, interface card, and inter-
face drivers must all be configured properly. To configure the SR430, the GPIB address must be set in the
SETUP menu. The default GPIB address is 8; use this address unless a conflict occurs with other instruments
in your system. The SR430 will be set to GPIB address 8 whenever a reset is performed (power on with the
[CLR] key down).
Make sure that you follow all the instructions for installing the GPIB card. The National Instruments card can-
not be simply unpacked and put into your computer. To configure the card you must set jumpers and switches
on the card to set the I/O address and interrupt levels. You must run the program "IBCONF" to configure the
resident GPIB driver for you GPIB card. Please refer to the National Instruments manual for information. In
the example below, the SR430 is installed as a device named "mcs".
Once all the hardware and GPIB drivers are configured, use "IBIC". This terminal emulation program allows
you to send commands to the SR430 directly from your computer's keyboard. If you cannot talk to the SR430
via "IBIC", then your programs will not run.
Use the simple commands provided by National Instruments. Use "IBWRT" and "IBRD" to write and read from
the SR430. After you are familiar with these simple commands, you can explore more complex programming
commands.
Binary Transfer Speed
The example program uses the BINB? binary data dump command to transfer data from the SR430 to the
PC. Using a 12 MHz AT, a 16k record takes 0.8 second to transfer to the PC.
