6.4. Trigger input
An external trigger input can be applied to the
input selected Line Selector. 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 Trigger
Activation.
Trigger input level is 4 V
2 V.

6.5. Exposure Active output
Exposure Active signal (positive) is found on
Opt-out on Hirose 12P or TTL out on D-sub
9-pin connector. The output circuit is 75
complementary emitter followers. Output
level
3 V from 75
(no termination). It can
be changed to the open collector signal.
When the open collector is used, the
maximum current is 120mA. However, if a
current of more than 50mA is flowed, it is
necessary to use bigger diameter wires for
connecting pins #8 and 9. If narrower-gauge
wires are used, it may not work properly
due to resistance issues.
This output can be changed to open collector Fig.16 Exposure Active output
signal by SW500.

Initial Trigger Activation Set:
If the TTL trigger signal is input through D-SUB 9 pin, there are several
functions inside the camera using TTL. And each function has the setting of
the trigger activation, the camera sets the initial processing in accordance
with its priority. The initial Trigger Activation Set function, however, forces
to set the input polarity after the power is ON.
Refer to
9.2.4.1 Initial Trigger Activation Set.
