individual input connected to a sourcing output, wire an external resistor between
the AT6n00's trigger input terminal and ground (see illustration). The resistor
ISO GND
provides a path for current to flow from the device when the output is active.
+5VDC
Connecting to a sinking output? Set the trigger input's active level to low
with the INLVL command (Ø = active low, default setting ).
6.8 KΩ
Connecting to a sourcing output? Set the trigger input's active level to
high with the INLVL command (1 = active high).

Thus, when the output is active, the TIN status command will report a "1"
(indicates that the input is active), regardless of the type of output that is
connected.
ISO GND
For details on setting the active level and checking the input status refer to the
INLVL and TIN command descriptions in the 6000 Series Software
Reference Guide .
TRG-x connected to GND (normally-open switches).
The active level (default is active low) can be changed
with the INLVL command.
These inputs are like the general-purpose inputs on the
50-pin header. The differences are (1) the triggers are
pulled up via the AUX-P pull-up terminal; and (2) the
triggers can be programmed with the INFNCi-H command
to function as position capture inputs (encoder & motor
position is latched within 50µs) and registration inputs.
These four terminals
(which include TRG-C & TRG-D)
are not available on the AT6200.
+5V connected to AUX-P (sourcing current).
Provides +5V power to the TRG input pull-up resistors (the AT6n00 is
shipped from the factory wired in this configuration). As an alternative,
you can connect AUX-P to an external power supply of up to 24VDC.
NOTE: AUX-P is also the pull-up for POS, NEG, HOM, & P-CUT inputs.
SINKING CURRENT: To make these inputs sink current, connect AUX-P
to GND.
