Trigger Inputs
I/O Connector
+5V connected to AUX-P and V_I/O
(sourcing current).
Pr5V power to the TRG-A & TRG-B input pull-up resistors. As an alternative,
you can connect AUX-P to an external supply of up to +24V (but do not use both the
on-board +5V terminal and an external 5-24V supply). If V_I/O is connected to a +5V
supply (on-board or external), AUX-P can be connected to a supply of up to +24V.
If V_I/O is connected to an ex24V supply, AUX-P must also be connected to
+24V (or to GND).
Switching levels depend on voltage at V_I/O (LOW
£
1/3 of V_I/O volts; HIGH
³
2/3 of V_I/O volts).
NOTE : AUX-P and V_I/O are also used by the HOM, NEG, POS & P-CUT inputs.
SINKING CURRENT : To make the trigger inputs (as well as HOM, NEG, POS & P-CUT) sink
current, connect AUX-P to GND.

ENCODER Connector
Internal Schematic
TRG-A/B 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 powered by the voltage applied
to the V_I/O terminal; and (2) the triggers can be programmed
with the
INFNCi-H
command to function as position capture
inputs and registration inputs.
Similar circuit for TRG-A.

If you will be connecting to a combination of sourcing and sinking outputs,
connect
AUX-P
to
+5-24V
to accommodate sinking output devices. Then for each
individual input connected to a sourcing output, wire an external resistor between
the ZETA6104Õs trigger input terminal and ground (see illustration). 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.
