The uReader system allows, safely and without altering the vehicle manufacturer's warranty, reading real time data of the CANbus. In a easy and standardized way information is obtained without the vehicle manufacturer FMS Interface. The uReader system sends all FMS standard SPNs and additionally the J1939, whenever they are available on the vehicle.

With uReader telematics platforms can implement in its AVL and FMS the new strategies in fuel economy and driving habits.

What is the FMS interface?

FMS Interface acts as a firewall limiting the data that can be obtained through the CANbus. It is the only connection point allowed by manufacturers to make the connection without losing the vehicle's warranty. Most vehicles do not have the FMS Interface enabled, so you can not get CANbus data without altering the warranty.

The uReader system does not require electrical connection to CANbus. Using a capacitive coupling system is possible to get all the bus information without altering the manufacturer's warranty.

uReader system:

  • replaces the FMS interface.
  • is smart and automatically detects the polarity and the speed of the bus.
  • transforms the signals from the vehicle to FMS standard.
  • filters unnecessary data making available only the relevant ones.
  • is compatible with most of trucks and buses manufacturers in the market.

The vehicle handles all communications (EDC, Retarder, Cruise, EBS, ABS, Injection, Fuel level, etc.) via internal CANbus. With uReader vehicle data can be read by any device with serial port, so you can have access to all information. uReader is compatible with other vehicle devices and can be combined with GPRS communications and GPS navigation..
