Use the PR command to enable internal pull up/down resistors for each digital input. Use the PD
command to determine the direction of the internal pull up/down resistor.
Queried sampling
You can use the IS command to query the current state of all digital input and ADC lines on the
device. If no inputs are defined, the command returns with an ERROR.
Field Name Description
1 Sample
sets
Number of sample sets in the packet. Always set to 1.
2 Digital
channel
mask
Indicates which digital I/O lines have sampling enabled. Each bit
corresponds to one digital I/O line on the device.
