Typical causes of error in CAN Bus systems include the following:

• Incorrect Channel settings for the incoming CAN signal, i.e. CAN format, CAN id, Byte position Byte length.
• Wrong Baud Rate between connected modules and logging system. No data will be transferred at all.

• CAN High and CAN Low connected the wrong way round. No data will be transferred at all.

• Lack of termination resistor. This will cause intermittent bursts of, or, no data to be transferred.
• The CAN port assignment is set the wrong way round - There are two CAN ports on a VBOXIII.
