ETAS Hardware Description
According to the CAN specification, one bus terminating resistor of 120 ohm is
required at each of the two open ends of the bus. It must be connected to the
cable or the plug.
ETAS offers cables and terminating resistors of 120 ohm to set up CAN net-
works.
Some CAN networks are already terminated (for example in a vehicle), so no
additional termination is required.
3.5.5 Minimum Requirements for the CAN Connection
At least the following connections are required in order to establish a connection
to the CAN network:
• Pin 2 CAN Low
• Pin 7 CAN High
• Pin 6 or Pin 3 GND (either one of the pins can be connected)
The ground connection (GND) must be identical to the ground connection of the
other CAN nodes on the bus.
