Introduction

Safety warnings

Caution
Caution
Electrostatic discharge
The camera contains sensitive electronic components which can be destroyed by electrostatic discharge.
Use sufficient grounding to minimize the risk of damage.
Environmental conditions
Operate the camera in a dry and dust free environment. The working temperature range (temperature of the camera housing) depends on the camera model:
• Pearleye P-007 LWIR: + 25 °C to + 45 °C
• Pearleye P-030 LWIR: + 15 °C to + 35 °C
Only in this temperature range the camera reaches optimal image quality. Outside the optimum temperature range, the image may look oversaturated.
Regarding the signal quality of the camera it is an advantage to operate the camera under constant ambient air temperature. This can, e.g., be facilitated by assembling the camera on a bigger metal corpus or by an additional active temperature regulation.
The red LED at the backside of the camera (L3) or the value of the register T serves for examination. If L3 permanently lights up or rather the lowest bit of T is set, the temperature of the camera housing is outside the optimum. In this case provide additional heating or cooling.
Note
Warm-up period
The warm-up of the camera takes 20 to 30 minutes.
To achieve best performance and accurate temperature measurements, wait until the warm-up is complete.

Start-up

Start-up
A Gigabit Ethernet port (1000Base-T) on the host computer is necessary.
1. Connect the camera with the appropriate data cable to the computer.
2. Plug the 15-pin connector of the power supply to the camera.
3. Switch on the power supply.

Camera control commands

To configure the internal image processing, a serial command interface is pro­vided. By default this command interface is internally routed to the Gigabit Ethernet port, but the RS232 signals at the 15-pin D-sub connector may also be used.
To access it, a serial terminal program employing the PC’s RS-232 COM port is required.
For Gigabit Ethernet the camera functions are controlled via GigE Vision fea­tures. This GigE Vision features are internally mapped to direct camera control signals or the serial commands accordingly.
Note
Refer to the corresponding control and command chapters throughout this manual to learn more about the GigE Vision feature mapping.
If the serial interface is routed over the 15-pin D-sub connector, it might be advantageous to use HyperTerminal to manually control the camera, since it is part of Microsoft® Windows® deliveries.
AVT provides the software AcquireControl: this can operate the camera’s serial port inband via the Gigabit Ethernet interface or externally via PC standard COM ports. Type <CTRL>+Y to get a camera control terminal window there.
By default the serial interface uses the following parameters:
• 115200 Baud
• 8 data bits
•1 stop bit
• No parity
• No handshake
The baud rate is factory-adjusted to 115200 but can also be configured to other values (see Chapter Advanced parameters and commands on page 46).
22
Start-up
Each command consists of a command letter, followed by an equals sign and a parameter value in hexadecimal number representation. The command letter is case sensitive. Hexadecimal values are always upper case and consist of 1 to 4 digits. The command is activated by a carriage return ([CR], ASCII character number 0x0D).
Serial communication operates in echo mode by default. This means that each character received by the module is echoed back to the sender.
In all command examples the characters sent to the camera are represented in
Bold Courier Font and the camera’s answer in Plain Courier Font.
The serial commands have the following fixed scheme:
>B=wxyz[CR]
Sign Description
B Command or parameter letter
(upper and lower case letter have different meaning)
= Equals sign (0x3D) wxyz 1-4 digits long value in
hexadecimal number representation (capital letters)
[CR] Carriage Return (0x0D) [LF] Line Feed (0x0A)
Table 6: Scheme of serial commands
Example (activate correction data set number 0):
1. The user sends the four characters
S=0[CR]
2. The camera answers with seven characters
S=0[CR][CR][LF]>
3. A terminal program without local echo displays
S=0

After successful execution of the command, the command input character > is output. If any error occurred somewhere previous to the prompt a question mark character ? is displayed.
To query a parameter value, send the corresponding command letter followed by the equals sign and a question mark character:
>s=?[CR]

Start-up
If the intended action does not need any parameter, it is sufficient in most cases to send the command letter only, directly followed by [CR].
At the beginning of a command sequence it is good practice to check the serial communication by sending just a [CR] to the camera and verify that the com­mand prompt > is returned. There is an input buffer holding a few characters but no hardware handshake. Thus a sequence of commands should not be sent to the camera without awaiting the intermediate input prompts. Otherwise the camera’s serial input buffer may overflow.

Adjust the image processing

Subsequently the important commands for quick starting the image correction of the Pearleye P-007 LWIR / Pearleye P-030 LWIR are mentioned. All further parameters and a description of the correction modules can be found in Chapter
Image processing on page 34.
The camera is configured ex-factory with parameter settings which ensure a basic image correction. Pearleye P-007 LWIR /Pearleye P-030 LWIR are equipped with multiple correction data sets for different operation conditions. the image quality can be improved by activating another correction data set if the conditions of the camera have changed. In addition the Pearleye P-007 LWIR / Pearleye P-030 LWIR models feature an electromechanical calibration shutter that can further enhance the quality of the corrected image. Use the serial command k=0, to select a good data set automatically. This command also controls the shutter.
Note

Control connector

Camera I/O connector pin assignment (15-pin D-sub connector)

This connector is intended for the power supply as well as for controlling the camera via its serial RS232 interface over a COM port.
Furthermore, some output signals are available, showing the camera state.

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 rec­ommended 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 exter­nally via a RS232 COM port.
A simple terminal program (e.g. HyperTerminal) is sufficient for manually con­trolling the camera.
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.

Trigger input (Reset) (pin 10, 11)

Due to a rising edge at the trigger input the image readout 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.
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).
