This is a downstream E-blocks peripheral module, designed to be controlled by one of the upstream E-blocks processing boards which are available in a variety of MCU/CPLD architectures.
Used to insert a number of different faults onto a CAN bus Includes an RJ45 connector to connect between a CAN system and a car
This E-Block allows investigation of a CAN bus system by introducing a variety of faults into the network. The E-Block is capable of introducing up to eight individual faults onto the CAN network.
E-Blocks CAN Bus Faults Board Features
- Short to Ground
- Short to VCC
- Open Circuit
- Partial Open Circuit
- All faults available on CAN-H and CAN-L
- Test points
There are three connections to a CAN system from the Faults E-Block. These are the input and output CAN buses that use the screw terminals, or the Kvaser analyzer interface that uses the D-type connector.
Faults are introduced into the system by means of the eight switches on the CAN Faults E-Block. Each switch enables a different fault onto either the CAN-H or CAN-L lines. Switches F1-F4 introduce faults onto the CAN-L data line; switches F5-F8 introduce faults onto the CAN-H data line. For the partial open circuit fault, there is a 47K Ohm potentiometer assigned to both the CAN-L and CAN-H lines which varies the resistance of the open circuit.
