MoTeC BR2 BTX - Manual (Page 6)

4 Overview
CAN Bus Connection Method
This is the recommended method for use with the MoTeC ADL, and the
only method for use with an MDD.
When the receiver detects any Beacon Transmitter it sends the
transmitter number to the connected device via the CAN Bus.
ADL
The ADL must be configured to use the same Mode and ID as
the Transmitter. All other beacon transmitters will be ignored.
The BR2 Beacon Receiver does not normally require the
configuration to be changed when used with an ADL. See the
Beacon Receiver section for more detail.
MDD
The MDD does not require configuration however a special
configuration method is required for the Beacon Receiver when
used with the MDD. This is done using the BR2 Configuration
program. See the Beacon Receiver section for more detail.
Switched Output Connection Method
This method is used for other MoTeC devices that do not support the
CAN Bus connection method such as the MoTeC M8 and M800 ECU.
The BR2 must be configured to only recognise a particular beacon.
This is done using the BR2 Configuration program.
When the BR2 detects a transmitter with a matching Mode and ID a
signal is sent to the connected device via the switched output.
See the Beacon Receiver section for more detail.
