5. Input and output
5.1
CoaXPress interface standard
The EL-2800M-CXP and EL-2800C-CXP use CoaXPress as their interface. CoaXPress is a
PLUG-AND-PLAY interface and connects the camera and the frame grabber board by coaxial cable(s).
Its maximum transfer rate is 6.25 Gbps per one coaxial cable. Additionally, CoaXPress interface
supports power supplied through the coaxial cable as well as communication signals. In the
CoaXPress interface, multiple coaxial cables can be used in order to achieve a faster transfer rate or
a reduced transfer rate can be used to extend the cable length.
In the EL-2800M-CXP and EL-2800C-CXP, a single coaxial cable system is used.
Camera
The distance between camera and frame grabber board depends on the bit rate of the video and the
cable used. Among the unique features of CoaXPress is its ability to supply DC power and provide
trigger timing accuracy.
The maximum power supply per one cable is 13W with DC+24V voltage. The accuracy of the trigger
is ±2 ns at 3.125 Gbps.
The CoaXPress compliance labeling is assigned to the following five cable types and the maximum
bit rate and transmission length is indicated in the table below.

In the EL-2800M-CXP and EL-2800C-CXP, the maximum bit rate is 3.125 Gbps for Monochrome and
Bayer color and 6.25 Gbps for RGB color per one cable.
