Computer Control
Introduction
The Vortex laser system can be operated remotely through either the
parallel IEEE-488 (GPIB) interface or the serial RS-232 interface. Most
computers have RS-232 interfaces built in. In order to use the IEEE-488
interface, a special card or interface box is necessary. The IEEE-488
interface is many times faster than the RS-232 interface and can be
used to communicate with up to 30 instruments at the same time. RS-
232 is limited to communication with one instrument at a time.
All front-panel operations are available through computer control. In
addition, several functions are unique to computer control.
Before attempting to communicate with the instrument, you must set
the device address (for IEEE-488) or the baud rate (for RS-232) via the
front panel. Upon receiving a command over the computer interface,
the front-panel functions are locked out. Use the Local button on the
front panel to re-enable the front panel.
Using the IEEE-488 Interface
The IEEE connector on the back of the Vortex controller allows for
remote operation through a standard IEEE-488 (GPIB) cable. The
connector is a standard, female, 24-pin IEEE-488 connector for use
with a standard shielded IEEE-488 cable.
In order to function properly, the Vortex must have a GPIB address that
is unique from all the other IEEE-488 components attached to your
computer.
