Using fast block/slow block transmission
DDU 10 telemetry uses available bandwidth of Telemetry Unit FM 40 (19,200 baud -> ap-
prox. 1,700 bytes/s). The bandwidth has to be divided into channel information 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 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).
