Using fast block/slow block transmission
DDU 8 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 informa‐
tion to be transmitted 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
transmission 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 tempera‐
ture).
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.
Adding a recording
DDU 8 supports up to two independent recordings.
To add a recording, select ‘Add Recording’ from the context menu of the Logger
in the DDU 8 Project Tree.
Maximum two Recordings are possible. In the DDU DTM Software the 2nd Re‐
cording is reserved for Scruteneering Data. This Recording is invisible (protected).
Adding a recording group
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.
