Control Connector (15 pin SUB-D Jack)

Pin Assignment of the Control Connector
This jack is intended for supplying power as well as for control signals of the camera. Furthermore
some output signals are available, showing the camera state.

Power Supply (Pin 1 - 4)
The camera requires 12V +5% DC and maximum 1.5A. The voltage should not fall below 12.0V and
should not exceed 12.6V. It is recommended to use respectively both pins (1+2, 3+4) for power
supply.
5.3
Serial Interface (Pin 7, 8)
By use of the serial interface at pin 7 and 8 the camera can be controlled externally via a RS-232 COM
Port. A simple terminal program (e.g. HyperTerminal) is sufficient for manually controlling the
camera. Please note that operating this serial interface and the second available port (via Gigabit
Ethernet interface) concurrently may lead to unexpected results. Both interfaces share the same receive
buffer and thus the characters of simultaneously sent commands may be randomly mixed up. See
chapter 10.7
for more information about serial interface configuration options.
5.4
Trigger (Reset) Input (Pin 10, 11)
Due to a rising edge at the trigger input the image exposure is reset and the camera immediately starts
to output the first line of the new image. In this way a synchronization of several cameras is possible.
Please note that a reset event can render up to two output images invalid. The first image may have
fewer lines because its output was aborted by the reset event. Additionally, the intensity of the second
image may be inaccurate because the microbolometer pixels’ minimal integration time was not
reached. Avoid reset events during integration of correction data or execution of the automatic
calibration function (
k
).
