6 CAN Specification

There are two CAN interfaces on the C60 logger. C60 CAN 1 will be used for "Team"
communication, on this bus the team is required to send the "Team Transmitted
Channels". The other bus (C60 CAN 2) will be used solely for scrutineering
components, no components other than those listed on the wiring diagram are
allowed on the Scrutineering bus.
Team CAN Bus:
The team CAN bus will be used to transfer vital information between the team and
the Scrutineering System. The team CAN bus must be laid out in a linear fashion,
with a termination resistor (120 ohm) at each end of the bus. The team bus is
required to be 1 Mbit and conform to CAN 2.0B specifications.
Scrutineering CAN Bus:
The scrutineering CAN bus will link all of the IMSA GT Spec Scrutineering System
components. This bus must be laid out linearly with a termination resistor (120
ohm) on each end of the bus. Only those components listed in this document
may exist on the scrutineering CAN bus!
