Inputs and Outputs

5.1

Input channels

Analog inputs
The DDU 8 analog inputs accept an input signal of 0 to 5 V. A 3.01 kOhm pull‐up
resistor can be activated by software.

Digital inputs

The digital inputs of the DDU 8 accept 0 V to 5 V signals of Hall‐effect sensors by
default. Connect the output of the Hall‐effect sensor to the REVn.
5.2

Output channels

Sensor power supply
The DDU 8 has two types of sensor power supply: 5 V and 10 V regulated volt‐
age. The regulated 5 V and 10 V outputs can deliver 350 mA each. They are short
circuit protected to battery voltage and GND.
5.3

Communication channels

CAN bus
The DDU 8 has two CAN buses configurable as input and output. Different baud
rates are selectable. Please note that the DDU 8 does not contain any CAN termi‐
nation resistors. Thus the CAN termination resistors need to be integrated into
the wiring loom.
Ethernet channels
The DDU 8 has two 100 MBit full duplex Ethernet communication port. The port
is internally connected with an Ethernet switch. The Ethernet port has 'cable auto
crossover' functionality.
RS232 ports
The DDU 8 has one RS232 serial port. Baud rate for the port is programmable.
RS232 port is reserved for GPS receiver.
