These commands set the functions of the three digital port pins. The
pin functions are saved in non-volatile memory.
DIO The pin is a general-purpose ground-referenced digital input/output. The output
can be set with
DINPut The pin is in digital input-only mode. The digital output data of the
corresponding pin is ignored.
TOUTput The pin is configured as a trigger output. When configured as a trigger output,
the pin will only generate output triggers if the Step or List transient system has
been configured to generated trigger signals.
TINPut The pin is configured as a trigger input. When configured as a trigger input, the
pin can be selected as a source of measurement and transient trigger signals.
FAULt Applies only to pin 1. Setting FAULt means that pin 1 functions as an isolated
fault output. The fault signal is true when any output is in a protected state
(from OCP, OVP, OT, PF, or INH). Note also that Pin 2 serves as the isolated
common for pin 1. When pin 1 is set to the FAULt function, the instrument
ignores any commands to program pin 2. Queries of pin 2 will return FAULt.
If pin 1 is changed from FAULt to another function, pin 2 is set to DINPut.
INHibit Applies only to pin 3. When pin 3 is configured as an inhibit input, a true signal
at the pin will disable all output channels.
These commands set the polarity of the three digital port pins. The
pin polarities are saved in non-volatile memory.
Setting a polarity to POSitive means that a logical true signal is a
voltage high at the pin. Setting the polarity NEGative means that a
logical true signal is a voltage low at the pin. For trigger inputs and
outputs, POSitive means a rising edge; NEGative means a falling edge.
