Signal Specification. Central Electronic Module (CEM)

Signal specification

Connector B2, 26 pin
All the values given below are between the terminal stated in column 1 and terminal #A1 (ground).
The terminals in the central electronic module (CEM) connector B2 correspond to terminals A1-26 on the breakout box.

Caution! It is important that the breakout box is connected and that the ground terminals have been checked before readings are taken.




U = DC in volts (V)
U bat= battery voltage
U low= voltage near 0 V or 0 V










Connector B1, 12 pin
All the values given below are between the terminal stated in column 1 and terminal #A1 (ground).
The terminals in the central electronic module (CEM) connector B1 correspond to terminals A31-42 on the breakout box.

Caution! It is important that the breakout box is connected and that the ground terminals have been checked before readings are taken.




U = DC in volts (V)
U bat= battery voltage
U low= voltage near 0 V or 0 V






Connector F, 16 pin
All the values given below are between the terminal stated in column 1 and terminal #A1 (ground).
