Digital Control Port

A Digital Control Port consisting of seven I/O pins is provided to access various control functions. Each
pin is user-configurable. The following control functions are available for the I/O pins. See
Programming Reference
The following table describes the possible pin configuration for the digital port functions. For a
complete description of the electrical characteristics of the digital control port, refer to the
Specifications section.
Function
DIO General-purpose ground-referenced digital input/output function. The output can be set with
al:OUTPut:DATA.
DINPut Digital input-only mode. The digital output data of the pin is ignored.
FAULt Applies only to pin 1. Pin 1 functions as an isolated fault output. The fault signal is true when any output is in a
protected state. Pin 2 serves as the isolated common for pin 1. When pin 1 is set to the FAULt function, the instru-
ment 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 the output.
ONCouple Applies only to pins 4-7. The ONCouple pin synchronizes the output On state between instruments. Only one pin
can be configured as an ONCouple. The pin functions as both an input and an output.
OFFCouple Applies only to pins 4-7. The OFFCouple pin synchronizes the output Off state between instruments. Only one
pin can be configured as an OFFCouple. The pin functions as both an input and an output.
TINPut A trigger input pin can be selected as the source for measurement and transient trigger signals. See
:ACQuire:SOURce
TOUTput A trigger output pin will generate output triggers from any subsystem that has been configured to output trigger
signals.
Common Applies only to pin 8. Connected to ground.
