By using CAN-filter the only odometer can to be programmed.
The CAN Filter can be configured by the USB or CAN Bus and works in Differential Mode (+NRZ).
Two version of Can Filters are available:
Low speed communication is defined to be below 125 kBit/sec
High speed communication is defined to be above 250 kBit/sec
* NOTE: To prevent the damage of the USB port while configuring the CAN
filter, the protection diode is used in the USB power circuit
