Using fast block/slow block transmission
C 60 telemetry uses available bandwidth of Telemetry Unit FM 40 (19,200 baud -> approx.
1,700 bytes/s). The bandwidth has to be divided into channel information to be transmit-
ted high-frequently and low-frequently using the 'fast/ slow block' setting.
Channels are grouped into 8 blocks which are transferred each cycle:
– Fast block (Block 1) is transferred every cycle and used for a high-frequent transmis-
sion of channel information (e.g. speed, rpm).
– Slow blocks (Block 2...n) are transferred every n-th cycle and used for a low-frequent
transmission of channel information (e.g. tire pressure, oil temperature).
Transmission Scheme
If the maximum bandwidth of a block is reached, a warning will be displayed. To fix this
problem you can view the allocation of the channels and data rate in the 'Statistics' tab of
the Main Area. See chapter 'Recording statistics' for more information.
C 60 supports up to two independent recordings.
To add a recording, select 'Add Recording' from the context menu of the Logger in the C
60 Project Tree.
Maximum two Recordings are possible. In the DDU DTM Software the 2nd Recording is
reserved for Scruteneering Data. This Recording is invisible (protected).
Recording channels can be grouped.
To add a new group, select 'Add group' in the context menu of the recording. The groups
can be renamed to 'Gearbox', 'Aero', 'Engine', etc.
To display the global C 60 settings, open the 'Logger' window and click on the 'Settings'
tab at the bottom.
