DIGital subsystem
The commands in the DIGital subsystem control the digital I/O lines.
:DIGital:LINE<n>:MODE
This command sets the mode of the digital I/O line to be a digital line, trigger line, or synchronous line and sets
the line to be input, output, or open-drain.
Type Affected by Where saved Default value

Usage
:DIGital:LINE<n>:MODE <lineType>, <lineDirection>
:DIGital:LINE<n>:MODE?
The digital I/O line (1 to 6)
Sets the digital line control type; the options are:
• Allow direct digital control of the line: DIGital
• Configure for trigger control: TRIGger
• Configure as a synchronous master or acceptor:
Sets the line direction; the options are:
• Input: IN
• Output: OUT
• Open drain: OPENdrain
• Master: MASTer

See Details for valid combinations with line type.
Details
You can specify the line type and line direction parameters to configure each digital I/O line into one
of the following modes:
• Digital open-drain, output, or input
• Trigger open-drain, output, or input
• Trigger synchronous master or acceptor
A digital line allows direct control of the digital I/O lines by writing a bit pattern to the lines. A trigger
line uses the digital I/O lines to detect triggers.
