Section 3 Command Descriptions
3.3
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), 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, otherwise the Digital232 will generate a Conflict
Error.
The Strobe and Inhibit output lines are not pulsed when the Bit Set command is
sent.
An Bit n (1 thru 40) is set to logic one
Example:
@ reset the Digital232
C5 configure all ports as output
A22 set bit 22 to a logic one
A23XA24 set bits 23 and 24 to a logic one
