Camera Link Interface - JAI CV-M2 Operation Manual

5.4.5. Camera Link interface

The video output is Camera Link, where the 2 channels with 10 or 8 bit video are placed in a
base configuration. The digital output signals follow the Camera Link standardized multiplexed
signal output interface. The output driver is NS type DS90CR285, and the receiver is NS type
DS90CR286.
The data bits from the digital video, FVAL, LVAL, DVAL and EEN are multiplexed into the twisted
pairs, which are a part of the Camera Link. Trigger signals and the serial camera control are
feed directly through its own pairs. The trigger input can also be TTL on the 12 pin connector.
(TI=0 for CL. TI=1 for 12 pin). The serial camera control can be switches between the 12 pin
connector or CL by an internal switch HR/CL. Refer to 7.2
The 26 pin MDR connector pin assignment follows the Camera Link base configuration.
