Vehicle Network Tester (IVNT-03)

Intrepid Control Systems' Vehicle Network Tester (IVNT-03) allows users to connect test low-level physical layer capabilities of on-board controllers connecting to Classical CAN (Controller Area Network) as well as CAN FD (Flexible Data).

The IVNT supports low-level, physical layer validation on up to two dual wire CAN or CAN FD networks as well as supporting connection for data monitoring/transmitting on six additional dual wire CAN or CAN FD buses. Two of the supporting connections are Selectable CAN and can be configured to be single wire (SW) CAN bus, LSFT CAN bus, or Dual-Wire CAN or CAN FD. There are also up to four local interconnect networks (LIN). In conjunction with the included Vehicle Spy 3 software, the IVNT will test high-level application/diagnostic layer services and functions. The IVNT will run each test and give a Pass/Fail status.

The IVNT setup has been designed for ease and simplicity. Connect the controller to CAN High and CAN Low, power the unit, and start the test in the PC application software. After taking these few steps, you will receive a report on the entire system test. Individual tests can be selected and run as well.
