DOLPHIN
The inputs can be connected directly to +5 V. If higher voltage is used a resis-
tor will have to be switched in series: at +12 V use a 470 
Ω resistor, at +24 V 
use a 1.2 k
Ω resistor. (DOLPHIN)
OSCAR
The inputs can be connected directly to +5 V. If a higher voltage is used, an 
external resistor must be placed in series: at +12 V use a 820 
Ω resistor, at 
+24 V use a 2.2 k
Ω resistor. (OSCAR)
MARLIN
The inputs can be connected directly to +5 V. If a higher voltage is used, an 
external resistor must be placed in series: at +12 V use a 820 
Ω resistor and 
at +24 V use a 2.2 k
Ω resistor. (MARLIN)
GUPPY
The inputs can be connected directly to +5 V.

DOLPHIN
Voltages above +45 V may damage the optical coupler.
Caution

OSCAR
Voltages above +45 V may damage the optical coupler.

Voltages above +45 V may damage the optical coupler.

GUPPY
If using voltages higher than + 5 V the input of the cam-
era will be damaged.
To avoid damage of the input, use an external resistor in 
series (outside of the camera).
Recommendations for resistors by voltages higher than + 5 V:
At +12 V use a 18 k
Ω resistor.
At +24 V use a 47 k
Ω resistor.
