5.3.2 Trigger input
An external trigger input can be applied to pin#10 of
the 12-pin Hirose connector (when the command TI=1
has been set). The input is AC coupled. To allow long
pulses the input circuit is designed as a flip-flop
circuit. The leading and trailing edges of the trigger
pulse activate the circuit.
The trigger polarity can be changed by TA (Trigger
Activation).
Trigger input level is 4 V
2 V.
Trigger can also be applied through the Camera Link
connector, when the command TI=0 has been sent.

5.3.3 XEEN output
XEEN is on pin #9 of the 12-pin Hirose connector.
The output uses either a complementary
emitter follower circuit or open-collector.
The output of the complementary emitter
follower circuit is
3 V (no termination).
When the open collector output is used, the
maximum current is 120mA. However, if the
current is more than 50mA, use thicker cable
for connecting pins #8 and #9. If a thinner
cable is used, it might cause a malfunction
due to the resistance of the cable.
The output can be selected by switch SW500
located inside the camera (trigger IF board).
EEN is also found in Camera Link.
