Standard CAN broadcast

Standard CAN broadcast for RaceCapture and PodiumConnect

Alert Messages

This describes the CAN format for Pit to Car alert messages.

Messages are broadcasted in ASCII character format, with a maximum of 16 characters across two CAN messages.

Message priority is 0 - 2, with 0 = normal priority used for pit-to car alerts, and 1 - 2 reserved for future use.

Base address: 0xA100 (41216)

Address for message is calculated by the base address offset by priority:

  • Priority 0 address: 0xA100 (41216) / 0xA101 (41217)
  • Priority 1 address: 0xA102 (41218) / 0xA103 (41219)
  • Priority 2 address: 0xA104 (41220) / 0xA105 (41221)
CAN ID Byte 0 1 2 3 4 5 6 7
Base Address message character 0 1 2 3 4 5 6 7
Base Address + 1 message character 8 9 10 11 12 13 14 15
