Main Function Description
Device Management
Modify Device Name
Open the iDatum to find “Device Control” and expand it, there will display the device information that
including device model, version information sequence and etc. You can enter device name in the “Device
User ID” bar, shown as below.
In “Device Control” option，you can enable “Device Command” , “Device Reset” and “Device Temperature”
as actual needed, shown as below.

Image Format and Frame Rate
Camera Data Format
The camera supports multiple image formats，the ROI parameter values in the user setting will increase
image frame rate.
Color camera default output format is YUV 422 8，mono camera default output format is Mono8.
“ Y” means Support
，
“—” means nonsupport.
The color camera converts the original data to RGB8 via pixel interpolation algorithm.
Bayer GR， Bayer GB，Bayer BG，Bayer RG as shown as below.
Bayer GR Bayer GB Bayer BG Bayer RG
The camera with 12Bit ADC（Some model only support 10Bit ADC），but considering the user's
processing capacity of data volume, the 8bit data output is provided. In order to retain the gray level
output of the image data, the 8bits are extracted from the high-order as the output.
The corresponding numbers of Bytes to different formats are shown as below.
In the client software to find “Image Format Control” and expand it. To click “Pixel Format” you
can view the pixel format supported by the current camera to select right output mode according to your
actual demands. shown as below：
www.contrastech.com
Frame Rate
The following 4 factors determines the camera's maximum frame rate, they are Bandwidth, Pixel Format,
AOI Output Resolution and The Calculation Formula of Frame Rate in ROI.
Click and expand “Acquisition Control” to find “Acquisition Frame Rate”, enter right acquisition frame rate
to enable it，shown as below.
ROI
The camera's maximum frame rate is determined by following three factors：
Frame Readout The smaller image height, the less readout time and the higher frame rate.
Exposure Time The less exposure time, the higher frame rate.
Bandwidth The larger bandwidth, the higher transmission frame rate is supported.
If you are only interested in a certain region of the image, you can set a Region of Interest(ROI) for the
camera. Setting ROI can reduce the bandwidth of the image being transmitted.
Thus increasing the frame rate to some extent.
ROI setting steps: Click “Image Format Control” > “Width and Height” thus according to actual demands
to adjust the area of ROI. The parameters of Offset X and Offset Y represents the starting point in the
upper left corner of ROI. Shown as below.
www.contrastech.com
Image Acquisition and Transmission
The camera has 2 types of trigger mode, including internal trigger mode and external trigger mode.
Internal trigger mode including Continuous Mode and SingleFrame Mode; external mode including
software trigger and hardware trigger. Internal trigger and external trigger can be switched by On/Off
button under Trigger Mode, off refers to the internal trigger mode and On refers to the external trigger
mode.
Internal Trigger Mode
Under the internal trigger mode, user can control the camera continuously output images or output single
image. Click “Acquisition Control” > “Acquisition Mode” select “Continuous” to continuously output images;
choose “SingleFrame” to output single image. Shown as below.
External Trigger Signals and Working Mode
The external trigger signals types of trigger camera acquisition can be given by software or external
device. Under external trigger signal mode, the camera output image via following several working
modes: SingleFrame Trigger mode, Burst Trigger mode and Long Exposure Trigger mode.
Software Trigger
For the camera support software trigger mode, when user set software trigger, the client software can
send commands to camera to acquires and transfer images via Gigabit Ethernet.
Set Steps: Click “Acquisition Control” > “Trigger Mode” choose “on” to enable trigger mode. Select
“Software” as trigger source in “Trigger Source” click “Execute” in “Trigger Software” to send trigger
commands. Shown as below.
