Input and output circuits
In the following schematic diagrams the input and output circuits for video and timing signals
are shown.
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 0.7 V p-p without sync.
Fig.5. Iris video circuit
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 is 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 of the 12-pin HR connector. The
output circuit is 75
complementary emitter followers
or open collector. They will deliver a full 5 volt signal.
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.
Output level
4 V from 75
. (No termination).
EEN is also found in Camera Link.

Camera Link interface
The digital video is available via Camera Link, with 8- or 10-bit pixel depth, using the Camera
Link Base configuration. The digital output signals follow the Camera Link standard using
Channel Link chip sets.
The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the
twisted pairs, which are a part of the Camera Link. Trigger signals and the serial camera
control are fed directly through its own pairs.
The 26-pin Mini-CL SDR connector pin assignment follows the Camera Link base configuration.
For a detailed description of the Camera Link standard, please refer to the Camera Link
standard specifications found on AIA web site, www.machinevisiononline.org.
