e. Ensure that the Correct Mode and ID have been entered in the
ADL Lap Time and Number Setup screen.
3B. Diagnostic Channels
When using the CAN connection method the Receiver generates a number of
information channels that can be used to check the performance.
The Beacon Number channel is useful for checking the Mode and ID setting
of the Transmitter.
The Valid Receptions channel is useful for checking that the Receiver is
receiving a good signal each time past the Transmitter. This should normally
be between 10 and 21. If the number of receptions is low, it could be due to
the Transmitter being placed too closely to another Transmitter.
See Appendix D – BR2 CAN Messages for details.
4. Check the Operating Range
Check that the beacon system operates at greater than 1.5 times the required
distance. For example, if the beacon system must work at 10m then check
that it works at a minimum distance of 15m.
If the range is short:
a. Check if the receiver is aimed through glass or acrylic sheet as this will
affect the range. The range can be affected substantially, particularly if
the glass is tinted or treated.
b. Check that the Transmitter and Receiver are aligned correctly, both must
be within 5 ° of optimum (2° preferred).
c. Check that the LED on the Transmitter is green.
d. Check that the Receiver lens is clean (The rectangular black window)
e. Check that the Transmitter lens is clean (The round black window)
See Appendix A – Range Specification for more detail.
