First of all, connectors are shown once again for a easier finding of pins.

Notes:
1. Minimal connections for operating are D+, +UE and GND.
2. Fuse is recommended if short circuit to UBat cannot be excluded.
Attention: Applying this fuse can result in minor precision of applied sensors!
3. +UB1 is needed when 4A-High side outputs are used.
4. +UB2 is needed when 2.5A-High side outputs 1 to 8 are used.
5. +UB3 is needed when 2.5A-High side outputs 9 to 16 are used.

Notes:
1. Default CAN-Interface for KEFEX-Winflash is CAN1.
2. Standard mode for RS-232 is a three line serial connection (RxD, TxD, Gnd) with no handshake (neither hardware nor software).
3. Avoid short circuits on TxD-lines to GND or +U_Bat under all circumstances!!!
