Input and output circuits
In the following schematic diagrams the input and output circuits for video and timing signals
are shown.
Note: PMCL version does not have this function due to the lack of 12-pin connector.
5.4.1
Iris video output
This signal can be used for lens iris control
in Continuous and RCT modes.
The signal for iris video output is taken from the
video signal after the gain control. The signal is
1.0 V p-p with sync.

5.4.2
Trigger input
An external trigger input can be applied to pin 10
of 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 TP=1.
Trigger input level 4 V
2 V.
Trigger can also be applied through the Camera
Link connector, when the command TI=0 has been
sent.
5.4.3
XEEN output
XEEN is on pin 9 on 12-pin HR connector. The
output circuit is 75
complementary emitter
followers or open collector. They will deliver a full
5 volt signal.
When the open corrector is used, the maximum
current is 120mA. If more than 50mA current is
flowed, use large diameter cable. Otherwise, due
to the resistance of the cable, malfunctions might
be occurred.
This can be selected by a DIP switch located on
the rear board. As changing the position requires
removal of the circuit board, it is necessary to
consult with JAI sales representatives.
Factory default is complementary emitter followers.
EEN is also found in Camera Link. Fig. 9. XEEN output
