Operation
3.12 Sample IEEE Programs
Below are three sample IEEE-488 programs using
three different IEEE controllers. These programs
are intentionally very short and are intended as aids
to demonstrate to the programmer how to operate a
Digibridge using a typical controller. It is assumed
that the Digibridge address is set to 3.
3.12.1 Programming Hints
• The initiation (start) command is “G0”. That is
the number 0, not the letter O.
• It is good practice to begin a new program with
a ‘’P2’’ command. This will reset all parameters
to the known turn-on state. If ‘’P2’’ is used
later in the program, it will reset everything,
including Nominal Value and any Bin Limits
that may be set.
• An “X” command must be sent to enable data
output.
• The string “P2A10;M3X4Z2G0” should be sent
for the Short Circuit Zero. A frequency other
than 1 kHz can be sent, if needed.
• The string “P2A10;M1X4Z1G0’’ should be
sent for the Open Circuit Zero. A frequency
other than 1 kHz can be sent, if needed.
• All commands sent to the Digibridge must
be followed by an UNL (unlisten) and then
ATN (attention) must be unasserted.
