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 '

'. 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 (

) 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.

Bit

(1 thru 40) is set to logic one

Example:

reset the

Digital232

configure all ports as output

A22

set bit 22 to a logic one

A23XA24

set bits 23 and 24 to a logic one
