4 GND - Ground
Remarks:
1. Put JP20
jumper to add a 120Ω terminal resistor in your CAN network. Leave JP
20 open if the
CAN network already has terminal resistors.
2. Put JP21 jumper to connect the IOiPOS4808 logic V
LOG
to CAN_V+. Leave JP21 open
if the CAN network has a separate supply connected to CAN_V+.
