It is designed to correct the data stream transmitted from one device connected to the CAN bus to another. It is connected to a gap between the devices and allows either not to pass the selected data or to transmit it differently. It works in both directions at the same time. The programming is done using special software. The filter is configured via a USB port. When setting the CAN filter connected to the vehicle, there is a protective diode to prevent damage to the USB port from being damaged. There is also the option to configure the already installed filter via the CAN bus.
When you buy a filter from us you will receive one of these two filters (sent randomly)
