Note STINGRAY

Voltage above +30 V may damage the optical coupler.

The output connection is different to the AVT Marlin 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...4 and ground. See Figure 38: Output schemat- ics with external resistors R (pin no. from camera I/O connector) (STINGRAY) on page 59.

Typical delay is not more than 40 µs.
