|Sensor 1 | RS232 1 |r1 | oc7 |Voltage divider 1k / 1.37k |
|Sensor 2 | RS422 |r4 | oc4 |Pull-down 100k |
|Sensor 3 | UART 3 |u3 | oc4 |Voltage divider 1k / 1.37k |

|Sensor 7 | SPI 2 |s2 | oc1 |Pull-down 100k |
|Sensor 8 | IC only |only | |Voltage divider 1k / 1.37k |
|Sensor ID | Sensor function | Short name | OC port | IC max [V] |
|----------|:---------------:|------------|:-------:|-------------:|
|Sensor 0 | UART 2 |u2 | oc7 | 5 V |
|Sensor 1 | RS232 1 |r1 | oc7 | 3.3 V |

The IC ports with pull-downs are 5V compatible, while the voltage divided ones are multiplied with a factor of: 1.37k / (1k + 1.37k) = 0,57
