Bit Set An
The Bit Set command programs a logic one output to a bit described by the
argument 'n'. Setting a bit may represent either a +5 volt or 0 volt output, depending on
whether an Invert command (I16) has been sent. If data is active high (default condition),
then Bit Set outputs +5 volts. If multiple bits are to be set within the same command
string, an Execute command (X) must be included after every Bit Set command.
The bit which is being set must have been configured as an output bit by the
Configure command to be valid. The Strobe output line is not pulsed when the Bit Set
command is sent.
An Bit n (1 thru 40) is set to logic one
Example:
CLEAR 718
reset the Digital488
OUTPUT 718;"C5X"
configure all ports as output
OUTPUT 718;"A22X"
set bit 22 to a logic one
OUTPUT 718;"A23XA24X"
set bits 23 and 24 to a logic one
