Outputs
4 “TTL” Digital output, 10 kHz, PWM, 250 mA each
2 PWM High side; 7.5 A each, PWM, 50 Hz
4 PWM Low side; 2.2 A each, PWM, 10 kHz

5 switchable 5 V/12 V, 400 mA each
* The tooth count differential between any two of the PWM inputs is available two meas-
ure e.g. shaft torsion.
Upgrade Real Time Ethernet
Enables the VCU to operate as a real time Ethernet master or slave. Guaranteed latency
time of 1ms. Ideal for time critical data transfer as needed in online control algorithms
involving data from different devices.
Two interfaces allow for a ring topology (redundancy in case the RTE line experiences
damage).
The VCU features a reasonable set of SERCOS3 instructions although not the full SER-
COS3 standard is implemented. The ECU side can act as a SERCOS3 master; the logger
side can act as a SERCOS3 slave.
Upgrade CCP Master
Enables CCP master functionality to request data from foreign devices via CAN/CCP pro-
tocol.
