Camera interfaces

Pearleye Technical Manual V2.3.0

Power supply (pin 1-4)

The camera requires 12 V +5% DC and maximum 1.5 A.

The voltage should not fall below 12.0 V and should not exceed 12.6 V. It is rec-

ommended to use respectively both pins (1+2, 3+4) for power supply.

Serial interface (pin 7, 8)

By use of the serial interface at pin 7 and 8 the camera can be controlled exter-

nally via a RS232 COM port.

A simple terminal program (e.g. HyperTerminal) is sufficient for manually con-

trolling the camera.

Trigger input (Reset) (pin 10, 11)

Due to a rising edge at the trigger input the image readout is reset and the cam-

era immediately starts to output the first line of the new image. In this way a

synchronization of several cameras is possible.

Note



Operating this serial interface and the second available port

(indirect via GigE Vision features) 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 Baud rate (s) on page 59 for more information

about serial interface configuration options.

Note



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).
