4.1 Team CAN
4.1.1 Team Connector
The pinout of the Team Connector is shown in the table. No changes are allowed to
this arrangement. Termination of the CAN busses must be done in the car’s loom as
depicted in 4.1.2 and 4.1.3.

4 | System Architecture
16 / 47 IMSA Prototype Class Scrutineering Logger Bosch Motorsport
4.1.3 Team CAN 2
NOTE:
One termination resistor will be built into the scrutineering loom. The other
termination resistor must be present in the team wiring of the CAN
connection, external of the scrutineering loom.
CAN buses must be laid out in a linear fashion, with a termination resistor
(120 ohm) at each physical end of the bus.
4.1.4 Driver ID
The Driver ID will be an input on the same connector as the team CAN connections.
The Driver ID signal will be controlled by a different resistance value for each driver.
The resistor will go between the two pins for Driver ID with nothing else in the
circuit. The Driver ID and resistor value pairings are in the table below:

4.2 Power Supply
The following notations for power signals are used:
▪KL 30 is a main relay switched battery positive rail. KL 30 must go directly to the
car master relay. It may not be connected through a power box or other device.
▪KL 31 is an un-switched ground rail (same as battery negative terminal)

4 | System Architecture
18 / 47 IMSA Prototype Class Scrutineering Logger Bosch Motorsport
4.3 Harness
The scrutineering system harness has two major parts. The major pieces are the
engine harness and the chassis harness. These two meet with a bulkhead connector
located at the rear of the cockpit. The engine harness has an optional connector, if
used the smaller rear portion must be certified. An example layout is shown in
section 7. This layout may be deviated from; however, the components must remain
on the same harness and use the same connector. Contact an approved harness
builder for more information and specifics for individual applications.
All harness pieces must be certified individually and marked as such by a Bosch
Motorsport approved dealer. Harnesses must be purchased through a Bosch
Motorsport approved builder.
Initial harness builds may have extended lead times of 4-6 weeks or longer. Teams
and manufacturers are responsible for ensuring their harnesses are ordered with
time to be built for the first event it is to be used.

5 | Loom Certification
Bosch Motorsport IMSA Prototype Class Scrutineering Logger 19 / 47
5Loom Certification
All scrutineering looms will come certified and serialized from the builder. IMSA
reserves the right to require an additional HiPot inspection at any time.
The engine or chassis loom pieces may be certified individually without the
presence of the rest of the harness components. If a loom has additional
connectors all components of the loom to include all connectors shown in the
layout must be supplied for certification. Cost of additional inspections or re-
certification to be $200 per loom.

6 | CAN Specification
20 / 47 IMSA Prototype Class Scrutineering Logger Bosch Motorsport
6CAN Specification
There are two IMSA CAN interfaces that may be used for communication, on these
buses the team is required to send the “Team Transmitted Channels”.
Teams will be responsible for informing IMSA and Bosch which buses will be used
for ECU and team communications. These messages may be on the same bus.
CAN Buses:
The CAN buses will be used to transfer vital information between the team and the
Scrutineering System. The buses are required to be 1 Mbit and conform to CAN
2.0B specifications.
