6.3. XEEN output
XEEN is found on pin #9 on 12-pin HR connector.
The output circuit is 75
complementary
emitter followers. Output level
3 V from 75
.
(No termination).
When the open collector is used, the maximum
current is 120mA. However, if the current of
more than 50mA is flowed, it is necessary to use
bigger diameter wires for connecting pin#8 and
9. In case of narrower wires, due to its
resistance, it may not work properly.
This output can be changed to Open collector
signal by SW100.
EEN is found in Camera Link. It is high during
exposure.

6.4. Digital output interface (Camera Link
®
interface)
The video output is Camera Link with 3 x 8 bits RGB video placed in a base configuration, or 3
x 10 bits or 3 x 12 bits RGB placed in a Camera Link medium configuration. The digital output
signals follow the Camera Link standardized multiplexed signal output interface. The Camera
Link output driver is NS type DS90CR285MTD.
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 fed directly through its own pairs. The trigger input can also be TTL on the 12-pin
connector.

bit allocation
The AT-200CL outputs an RGB signal via Camera Link. A 3 x 8-bit signal is allocated via a Base
configuration through port 1, while a 3 x 10-bit or 3 x 12-bit signal is allocated via a Medium
configuration through both port 1 and port 2.
On the next page, there is bit allocation table.
