Connecting to a
lighting controller
When the expected
voltage is supplied
- When connecting to the illuminator trigger input of a lighting controller,
connect an auxiliary signal capable of sending out a strobe signal. To source the
voltage for the signal, use an external power supply.
If the power supply outputs the voltage expected by the lighting controller,
➠
you need to add an external pull-up resistor. The external resistor pulls the
voltage up to the external power supply's voltage (+V

Direct output connector
Note that if your lighting controller expects a 24 V signal, you can connect
❖
the wire of your external pull-up resistor to the 24 V wire-terminal of the
direct output connector.
Connect the GND wire-terminal of the direct output connector and the
ground of the lighting controller to a common ground.
Note that you must choose an appropriate resistance value for the pull-up
resistor based on the voltage (V) and current (I) that your lighting controller
expects for its trigger input signals. Also, you should choose a resistor rated
at a power higher than the expected peak power. The following formulas can
be used to calculate the required resistance (R) and the expected power for
that resistance (P).
