Tab 'LEDs'
The shift light configuration window appears.
Shift Light Configuration
1. Set up the shifting lights using the following configuration possibilities:
a) Choose the measurement channel for 'Revolution'. Revolution must have 1/min quantization.
b) Enter the limit value when the RPM hysteresis function is active. The RPM hysteresis function avoids
the high-frequent switchover of the measurement channel value.
c) Choose a predefined Pattern style.
d) Define the gear (must be ASCII quantization). Only if gear channel is used.
e) Define the RPM-limits individually for each LED and each gear.
f) Choose the measurement channel for 'Gear'. Gear must have an ASCII quantization (1st gear='1'= 49,
2nd gear='2'= 50, ...). (ASCII quantization is standard for the 'gear' channel of Bosch ECUs. If you get the
gear information of a different control unit as the Bosch ECU (e.g. a gearbox control unit), use the Gear
Lookup Table to translate numeric values to ASCII format. For more information see chapter
'Converting a gear channel to ASCII representation'.)
g) Choose the number and color of the LEDs corresponding to the RPM-limits shown in the table.
You can choose the number and color of each LED individually by right-clicking.
2. Click 'OK' when done.
The configuration is displayed in the DDU 8 LED Configuration window.
Converting a gear channel to ASCII representation
If you get the gear information of a different control unit as the Bosch ECU (e.g. a
gearbox control unit), use the Gear Lookup Table to translate numeric values to
ASCII format.
