MoTeC BR2 Beacon Receiver 15
Other
The LED may also glow dimly or erratically if it is receiving electrical
interference or a signal from another infrared source.
Connection Methods
The BR2 has two connection methods: CAN (Controller Area Network) or
Switched Output.
CAN Connection Method
The CAN connection method is the preferred method for connecting to the
ADL and the only method for connection to an MDD.
The BR2 should be connected to the vehicle CAN Bus. See Appendix J –
BR2 Wiring for details.
This method allows the BR2 to provide additional information to the ADL,
which provides improved diagnostic capabilities. The information that is sent
to the ADL is documented in Appendix D – BR2 CAN Messages.
Switched Output Connection Method
The Switched Output connection method can be used to connect to other
devices that do not support the CAN connection method such as a MoTeC
M8 or M800 ECU.
The BR2 should be wired to a suitable Digital Input on the ECU. See
Appendix H – BR2 Wiring (Switched Output) for details.
Special Notes
Both outputs are always used as follows:
CAN Mode
In CAN Mode the Switched Output is pulsed for every beacon received.
The BR2 could be used to trigger another device with its switched
output, while sending beacon signals to the ADL via CAN.
The LED diagnostics ignores an error on the Switched Output.
