Outputs OSCAR/MARLIN

The OSCAR and MARLIN cameras have 2 non-inverting outputs with open emitters. These are shown in the following diagram:

Note OSCAR/MARLIN

•Voltage above +45 V may damage the optical coupler.

•The output connection is different to the AVT Dolphin series to achieve higher output swing.

•Depending on the voltage applied at OutVCC and the type of input which you want to drive, it may be neces-

sary to switch an external resistor in series between GPOut1 and ground. The use of 1 kΩ @ 5 V or 2.4 kΩ @ 12 V can be recommended. Typical delay is not more than 40 µs.

Note

For information on output features (IntEna, Fval, Busy) and

 

configuration via registers see Technical Manuals.
