the corresponding DI+. You can set the programmable threshold voltage
between 1 V to 4 V.
The NI-9361 provides a 5 V pull-up on each DI+ terminal which can be enabled
individually. The 5 V pull up is about 1 kΩ, and is able to source up to about 5 mA of
current to the sensor signal line connected to DI+. The pull up is useful for sensors
with open-collector or open-drain outputs such as Hall Eect sensors. An
open-collector device does not actively drive the signal high and relies on an
external pull-up to perform this function.
In dierential mode, there is no programmable threshold voltage. The 5 V pull up is
disabled. The dierential line signals are connected to the corresponding DI+ and
DI- terminals.
Programmable Digital Filter
The NI-9361 has a digital filter on each of the digital input lines to filter unwanted
glitches on the digital input signal.
You can configure the following filter properties for each of the input lines:
■
Enable or disable the digital filter.
■
Minimum pulse width of the input signal that passes through the filter.
