1.1 Description of the EtherCAN/2

Figure 1:

Block circuit diagram

The EtherCAN/2 is an Ethernet-CAN-Gateway equipped with an ARM9 processor, which controls
the data transfer between CAN and Ethernet.
The Ethernet interface is suitable for 10 Mbit/s and 100 Mbit/s networks and can be connected via
an RJ45-socket.
The CAN interface can be connected via a 5-pin Combicon connector.
The interface is in accordance with ISO 11898-2, is electrically isolated and can be used for
transmission rates from 20 kbit/s up to 1 Mbit/s.
The connectors for the Ethernet-, CAN- and serial interface and the status LEDs are located in the
front panel of the top hat rail module and are easily accessible.
The 4-pin Combicon connector for the power supply is located in the case top side, easily
accessible.
