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

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 k
Ω @ 5 V or 2.4 kΩ @
12 V can be recommended. Typical delay is not more
than 40 µs.
