Trigger Inputs
Trigger Inputs 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 always internally pulled up to +5V
and are TTL compatible;
and (2) the triggers can be
programmed with the
INFNCi-H
command to function as position
capture inputs and registration inputs.
TTL compatible (switching levels: low
£
0.4V, high
³
2.4V).
Voltage range = 0-24V.

The resistor provides a path for current to flow from the device when the output is active.
PROGRAMMING TIP
Connecting to a sinking output? Set the trigger inputÕs active level to low with the
INLVL
command
(
¯
= active low, default setting ). Connecting to a sourcing output? Set the trigger inputÕs active
level to high with the
INLVL
command (
1
= active high). Thus, when the output is active, the
TIN
status
command will report a Ò
1
Ó (indicates that the input is active), regardless of the type of output that is
connected. 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 .
