4.3.3 Power Jumper Settings
The ProtoNode Carrier Board power jumper is set to position A by default, but can be changed to position
B for other power supply requirements.
Position A:
The Carrier makes use of a full-wave rectifying bridge. Can be used for 12-24 VAC input or
9
– 30 VDC input. At 9 VDC this becomes marginal.
Position B:
The Carrier makes use of a half-wave rectifying bridge. Best position for Grounded AC
Transformers and for using DC voltage down to 9VDC.
