Digital In | Out
Toggle to select In/Out digital function.
Digital In: Receive a signal from external device.
Digital Out: Send a signal to external device.
The input voltage range for digital I/O pins is 0 V to 5 V. To prevent damage to the
instrument, do not exceed 5 V or supply a negative voltage to the digital I/O pins.
Trigger In | Out
Toggle to select In/Out trigger function.
Trigger In: Receives signal that triggers set event.
Trigger Out: Sent trigger signal when specied. (BOST or EOST)
In List Mode, the Trigger In function can be used to trigger the next step when Trigger Source is set to Digital IO.
In Datalog, the Trigger In function can be used to start/stop data logging when Trigger Source is set to Digital IO.
Trigger Out is only available for list mode, step BOST and EOST.
Fault Out
Enable a fault condition, which generates a protection fault signal on the digital port.
Dierent conditions such as over voltage, over current, or over temperature will generate a fault event.
The fault event will “disable” all outputs without turning them o.
The outputs are “disabled” by setting the outputs as low as possible.
8.4.1 Polarity
Default: Positive
Set polarity of selected pin.
Positive
A logic true signal is received as a voltage high.
Negative
A logic true signal is received as a voltage low.
