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

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

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.
