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 kΩ 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 kΩ 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 kΩ resistor. (MARLIN)
GUPPY The inputs can be connected directly to +5 V.

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 kΩ resistor.
• At +24 V use a 47 kΩ resistor.
