 Handle the camera with care. Do not abuse the camera; avoid striking or shaking it. Improper handling

or storage could damage the camera.

 During camera use, do not wrap he unit in any material. This will cause the internal temperature of the

unit to increase.

 Do not expose the camera to moisture, or do not try to operate it in wet areas.
 Do not operate the camera beyond its temperature, humidity and power source ratings.
 While the camera is not being used, keep the lens or lens cap on the camera to prevent dust or

contamination from getting in the CCD or filter area and scratching or damaging this area.

 Do not keep the camera under the following conditions:

 Do not pull or damage the camera cable.

 In wet, moist, and high humidity areas
 Under hot, direct sunlight

 Use a soft cloth to clean the camera. Use pressured air spray to clean the surface of the glass. DO not

scratch the surface of the glass.

2. Output Signals

Set the output signals from the power/IO connector.
The following six output signals are selectable with the software or communication:

a. FrameTriggerWait

With the FrameTriggerWait signal, the user can check the camera conditions of the camera exposure and the image output
processing by the trigger signal.

1) High status (3.3V): No processing by the trigger signal. The camera accepts the trigger signal

2) Low status (0V): The camera exposes and the image output processing by the trigger signal
The camera’s default setting is that the input trigger signal is INVALID during the low status for this signal.
In order to start the exposure while the image is being output by the next trigger signal, please change the camera settings

(Device code: 001, Command: 13H) to accept the trigger signal while the image is being output.
Noise may appear on the image when the exposure is initiated while the image is being output. In this case, please change the

“H reset” of the exposure start mode (Device code: 00H, Command: 12H) in order to change the exposure start point to next
HD timing.

b. UserOutput

The status of this UserOutput signal can be changed with the “UserOutputValue”.

c. ExposureActive

The user can check the exposure time with the ExposureActive signal.

1) High status (3.3V): The camera is exposing

2) Low status (0V): The camera is not exposed

d. TriggerAuxiliary

This TriggerAuxiliary signal is the trigger signal.

e. TriggerInternal

This TrigerInternal signal is the trigger signal for the trigger delay time.

f. SensorReadOut

SensorReadOut signal is the FVAL signal (the image output period of the time).

In this trigger mode with positive polarity, the camera exposure starts at the rising edge of the trigger pulse and stops at the

falling edge of the trigger pulse. Therefore, if positive polarity exposure is selected, the exposure periods are the high states of

the trigger pulse.

In this mode, the exposure can be initiated during the video out from the camera without any horizontal noise. A SUB pulse is

generated to sweep the charges during the horizontal blanking period to prevent from getting horizontal noises.

The image will have horizontal noise that is caused by generating the SUB pulse during the video out during normal mode (H

4. Sequence for the saving commands to the EEPROM

Please use the following sequence for saving the commands to the EEPROM

a. Set “1” to the 80H.0 to accept the “write control to the EEPROM”.
b. Send the command and the save data with the EEPROM access command, which is set to “1” for the page selection.

c. The camera sends back one of the following receiving codes after writing the EEPROM.

01H: OK
17H: EEPROM write error

d. 80H.0 is changed to “0” automatically after writing the EEPROM

Note 1: When 80H.0 is “0” it will not save to the EEPROM
Note 2: When saving multiple sequences of commands: “10H, 11H, 12H and 13H” or “22H, 23H and 24H”.
Note 3: When saving multiple command data (which are not a sequence command) to the EEPROM it is necessary to operate

steps a.~d. the same number of times.
Example of a multiple command: “10H, 13H, 19H and 1BH” or “20H, 23H and 25H”.

Caution:
Width, Height and PixelFormat all effect the image data size.
Please use GenICam command name command when changing these values, as exampled in the following sample code.

In the case to change the Width

BOOL SetWidth( PvDevice *pDevice, PvInt64 lValue )
{
PvGenInteger* lGenInteger = dynamic_cast<PvGenInteger*>( pDevice->GetGenParameters()->Get( "Width" ) );
PvResult lResult = lGenInteger->SetValue(lValue);

return lResult.IsOK();
