## Pin description

### PT_CAN/PT_CAN2

Two canbus networks responsible for all communication with the transmission. 

This two networks have to be connected to the Can Gateway and to the transmission.

Please note:

PT_CAN is not terminated within the shifter.

PT_CAN2 is internally terminated with 120R resisor.

### Wakeup

This terminal has to be connected to Wakeup pin on Can Gateway.

### KL30B

This terminal has to be connected to KL30B out on the Can Gateway. 

**Please keep in mind that this is current carrying connection which has to be made with wire of 0.5mm<sup>2</sup>**

### KL31

This terminal is ground for the shifter.

**Please keep in mind that this is current carrying connection which has to be made with wire of 0.75mm<sup>2</sup>**

## Connection variants

### 8HP shifter with 8HP transmission or DCT shifter with DCT transmission

In case of connecting the shifter to compatible transmission, it is recommended to wire the shifter to both PT_CAN and PT_CAN2 interfaces.

In this case PT_CAN has to be terminated at the shifter end with 120R resistor.

### 8HP shifter with DCT transmission or DCT shifter with 8HP transmission

In case of connecting the shifter to incompatible transmission, Can Gateway has to do translation between the protocols.

To acheive this, it is recommended to connect PT_CAN2 to CAN4 on the Can Gateway and select appropriate options within the configuration.
