Packet Filter Block

The Packet Filter Block is used to selectively forward incoming CAN packets to the blocks output port. Each filter can be configured as either a "Pass Filter," where only matching packets get forwarded, or as a "Reject Filter," where all messages are forwarded except those that match. Packets can be added, removed, enabled, or disabled, all while the capture is still "live".

Packet Filter Features:

  • Support for filtering based on CAN 11-bit ID, CAN 29-bit ID, or J1939 PGN
  • Filter packets using either a "pass filter" or a "reject filter"
  • Select between forwarding or rejecting CAN error frames
  • Enable/disable checkbox and custom description for each filter item
  • Cut, copy, and paste between different filters
