Controls
Power switch
Switches the input power.
Reset button
This depressed button can be operated with a pen or other pointed
device. Pressing it causes both the control unit and the data acquisi-
tion unit to return to factory default settings.
Connectors
Power connector
Receives input 12 V DC power.
Clock in
Reference TTL clock input. Synchronises clock base of APDCAM
to external source. (Signal standard 3.3 V CMOS)
Clock out
Reference clock output. Can be used to synchronize clock base of
external device. (Signal standard 3.3 V CMOS)
Trigger in

fibre communication is desired.
Optical Ethernet
fibre
Fibre data connection to PC
LEDs
Temp.
Red light means temperature alarm. Some element of the camera is
overheated.
Overload
Red light means overload condition occurred, detector bias voltage
is switched off.
Comm.
Green light flashes when control communication occurs between
PC and camera
ADC
Data acquisition module state: Green indicates normal state, red
means error condition.
Control
Control module state: Green indicates normal state, red means error
condition.
Calib.
Yellow light means calibration light is on.
Shutter
Yellow light means shutter is open
HV
Blue light means detector bias voltage is on.
Ext. Clock
Green light means external reference clock signal is accepted.
Data out
Green light indicates data output to PC.
Gbit
