5.3. Input and output circuits
5.3.1 Trigger input
The External Trigger signal can be applied
either through the Camera Link connector or
at pin 10 of the 12-pin Hirose connector. The
command to change this setting is TI (Trigger
Input). TI=0 for Camera Link connector
(factory default) and TI=1 for 12-pin Hirose
connector. The input via the 12-pin Hirose
connector is AC coupled.
To allow long pulses, which may be required
when using the Pulse Width Control (PWC)
trigger mode, the input circuit is designed as a
flip-flop circuit. The leading and trailing edges
of the trigger pulse activate the circuit.
The trigger input polarity can be changed by
the command TP. At the 12-pin Hirose connector the External Trigger input is 4V ± 2V (TTL). It can
be changed to 75 ohm termination by a DIP switch setting (SW 1).
5.3.2 EEN / XEEN output (Exposure ENable)
This output corresponds to the exposure
(accumulation) time of the camera. It works
together with all operation modes. It is,
however, not active when the test pattern
function is enabled.
The EEN signal is available at the Camera
Link connector and at the 12-pin Hirose
connector at the same time.
At the Camera Link connector this signal has
positive logic.
At pin 9 of the 12-pin Hirose connector the
signal has negative logic, and is therefore
named XEEN. The output circuit is a 75 ohm
complementary emitter follower. The
circuit is powered from the 5V supply,
resulting in an output level of more than 4V.
It is not terminated.
