(2) A supply voltage is available on pin 1 of the connector to power an external trigger device. The voltage is equal to
the voltage of the incoming power supply to the board (on connector J9). The limit on the power supply pin on
each external trigger is limit 50 mA.
(3) The external trigger is compatible with a CMOS/TTL logic level (5 V logic). Alternatively, any voltage input in the
range 5 to 24 V can be accommodated. The trigger can be isolated or non-isolated.
