The Profinet interface supports 10/100 Mbit/s Ethernet. In the Linux operating
system it is available as network interface eth2. The MAC address of this
interface is stored within the OTP of the System on Chip.
| Pin | Signal |
|---|---|
| 1 | ETH1 TX P |
| 2 | ETH1 RX P |
| 3 | ETH1 TX N |
| 4 | ETH1 RX N |
| Shield | Ground (EVSE) |
The LAN interface supports 10/100 Mbit/s Ethernet. In the Linux operating
system it is available as network interface eth0. The MAC address of this
interface is stored within the OTP of the System on Chip.
| Pin | Signal |
|---|---|
| 1 | ETH2 TX P |
| 2 | ETH2 RX P |
| 3 | ETH2 TX N |
| 4 | ETH2 RX N |
| Shield | Ground (EVSE) |
The MCS interface supports 10 Mbit/s Ethernet. In the Linux operating
system it is available as network interface eth1. The MAC address of
this host interface is stored within the EEPROM on the SOM.
| Pin | Signal |
|---|---|
| 1 | 10-Base T1S P |
| 2 | 10-Base T1S N |
| 3 | Temp1 input |
| 4 | Temp2 input |

| 6 | Charge Enable (CE) |
| 7 | Insertion Detection (ID) |
| 8 | Ground (MCS) |
| Shield | Ground (MCS) |
The CAN interface is a full implementation of the CAN FD protocol specification
version 2.0B. It is available on Linux network interface can0, which has a
default bitrate of 500 kBit/s.
| Pin | Signal |
|---|---|
| 1 | CAN L |
| 2 | CAN H |
| 3 | Temp3 input |
| 4 | Temp4 input |
| 5 | Common ground for Temp3 and Temp4 |
| 6 | Charge Enable (CE) |
| 7 | Insertion Detection (ID) |
| 8 | Ground (MCS) |
| Shield | Ground (MCS) |
Wiring overview for the PT1000 Temperature Sensors
This wiring diagram shows an overview of connecting the temperature sensors to the Charge Control Y:
- Make sure you only connect PT1000 temperature sensors
- Connect sensor 1 between Pin 3 and Pin 5 of MCS
- Connect sensor 2 between Pin 4 and Pin 5 of MCS
- Connect sensor 3 between Pin 3 and Pin 5 of IO
- Connect sensor 4 between Pin 4 and Pin 5 of IO
Wiring overview for the Emergency Input
This wiring diagram shows an overview of connecting the emergeny input to the Charge Control Y:
- make sure the emergency input stays between 21.6V and 26.4V for normal behavior
- any other voltage is treated as error condition and triggers the safe state
- the voltage is measured against Ground (EVSE) (Pin 3)
State C is indicated by internally switching HV Ready In (Pin 4, Power & Safety) to HV Ready Out (Pin 5, Power & Safety). The short between HV Ready In to HV Ready Out is only done while the vehicle indicates state C AND Charge Control Y detects no safety issues.
