Introduction to GPIB Drivers
xPC Target uses a model for I/O that includes both Simulink blocks, for the
I/O drivers, and MATLAB structures for sequencing messages and commands.
This model provides increased flexibility and control over using only Simulink
blocks in your model
This section includes the following topics:
•
Hardware Connections for GPIB — Connect the target PC to a
GPIB-232CT-A controller from National Instruments.
•
Simulink Blocks for GPIB — Add setup, send, and receive blocks to your
Simulink model.
•
MATLAB Message Structures for GPIB — Create message structures to
sequence instructions to and from the GPIB controller.
Hardware Connections for GPIB
xPC Target supports connecting to a GPIB instrument bus with a
GPIB-232CT-A controller from National Instruments.
One end of the controller is connected to either the COM1 or COM2 port on the
target PC with a null modem cable. The other end is connected to the GPIB
instrument bus with a standard GPIB connector and cable.
