Usage
:DIGital:LINE<n>:STATe <state>
:DIGital:LINE<n>:STATe?
The digital I/O line (1 to 6)
Clear the bit (bit low): 0
Set the bit (bit high): 1
Details
When the line mode for a digital I/O line is set to digital output (:DIG:LINE<n>:MODE DIG, OUT),
you can set the line high or low using the <state> parameter. When the line mode is set to digital
input (:DIG:LINE<n>:MODE DIG, IN), you can query the state of the digital input line.
When a reset occurs, the digital line state can be read as high because the digital line is reset to a
digital input. A digital input floats high if nothing is connected to the digital line.
This returns the integer equivalent values of the binary states on all six digital I/O lines.
Set the state to zero (0) to clear the bit; set the state to one (1) to set the bit.
Example 1
:DIG:LINE1:MODE DIG, OUT
:DIG:LINE1:STAT 1
Set digital I/O line 1 as a digital output line.
Sets line 1 (bit B1) of the digital I/O port high.
Example 2
:DIG:LINE1:STAT?
Set digital I/O line 1 as a digital input line.
Query the state of line 1 on the digital I/O port.
