2. Introduction and Overview
2.1. Introduction
The IVNT-03 is Intrepid’s 3rd generation Vehicle Network Tester. It contains a fully functional “neoVI FIRE 2” device, except the 1st LIN channel, GPS and the front panel are not available. The front panel provides banana jacks and termination selectors for HSCAN and MSCAN, GND, power and VBAT LEDs, and the neoVI FIRE 2 uDB9 connector. The rear panel provides a HD26 connector for vehicle battery, LIN channels and the remaining CAN FD channels. The IVNT-03 provides the following features:
- Measurement of VBAT, VGND
- Measurements of the CAN H and L lines and differential measurement
- Adjustable resistive loading of CAN lines
- Adjustable capacitive loading of CAN lines
- Ground offset testing
- Shorting CAN lines to GND, VBAT, or each other
- ArbID and/or time based Bit Smash functionality
2.2. Package Contents
The IVNT-03 package includes both hardware and software:
2.2.1. Hardware
You should receive the following:
- The IVNT-03 device
- 12 Volt power adaptor
- Your choice of cable from among options (details are in Section 3.4)
- A microSD card for data logging (already installed in the unit)
- An industry standard USB “A/B” cable to connect the IVNT-03 to a PC
- You will also receive a Quick Start card to help you get going quickly with your device
2.2.2. Software
In the IVNT-03 package you will find a software/driver disc containing:
- A copy of Intrepid’s Vehicle Spy vehicle network software
- Drivers for the IVNT-03
- An API install kit containing the neoVI Explorer utility for configuring the device
- Documentation materials
If you opted for a download rather than a phsical copy: Links for downloading will be in the email
If you did not purchase Vehicle Spy, a free trial version of the program will be provided instead, which allows access to VSpy’s basic features.
It is also possible to control the IVNT-03 from within other software using APIs that the device supports.

2.3. Operational Overview
The IVNT-03’s operation can broadly be broken down into three categories: network interfacing; data acquisition and logging; and simulation and scripting.
2.3.1. Vehicle Network Interfacing
Using the provided cables, you can connect the IVNT-03 to either a bench test setup or an actual vehicle, and monitor live network activity. All channels are monitored simultaneously, and the data are hardware time-stamped. This data can be viewed in Vehicle Spy 3 or any other software using the intrepid APIs or J2534 pass through APIs.
2.3.2. Data Acquisition
The IVNT-03 enables the acquisition of data from networks with precise control over collection parameters. The data can be captured in PC mode using various features in Vehicle Spy 3.
2.3.3. Simulation and Scripting
Using Vehicle Spy or other software you can define transmit messages with custom data and send them manually or on a schedule of your choosing. You can also write intelligent scripts that implement arbitrary logic, and compile them into Core Minis that run within the device itself. This functionality allows you to create specialized test scenarios, and to simulate ECUs and gateways.
2.4. Summary of Key Features
Here is a summary of the device’s most important design, construction, operational and performance features:
2.4.1. Construction, Controls and Cabling
- Solid anodized aluminum case
- Ability to control CAN/CAN FD termination resistance on both channels
2.4.2. Power and Performance
- Fourth-generation neoVI architecture, offering over ten times the performance of earlier devices
- Field-upgradeable firmware
- Improved USB latency
- CAN FD baud rates supported upto 10Mbps
2.4.3. Network Interfaces and Features
- 2 dedicated DW CAN channels (ISO 11898-2)
- All Dual Wire CAN channels have CAN FD support
- Support for NON-ISO CAN FD and ISO CAN FD
- Software-programmable CAN termination resistance (Hardware as well)
- Real-time clock for 64-bit message time stamping
2.4.4. PC Interface
- High-speed isolated USB connection protects PC from potential damage
2.4.5. Advanced Features
- Device control by external software using three open APIs: neoVI DLL, SAE J2534, and TMC RP1210 A/B
2.5. Hardware and Software Requirements
2.5.1. Hardware:
A vehicle network, either within an actual vehicle or in a test bench environment.
2.5.2. Software:
A PC with an open standard USB 2.0 (or higher) port (TypeA/TypeC). You can use a USB hub, but we recommend that this be a powered hub to ensure that sufficient power is provided.
The setup program for Vehicle Spy will install the necessary drivers for IVNT-03. If you do not have a Vehicle Spy license, you can use the Vehicle Spy trial version for basic network interfacing and driver setup. Drivers can also be set up using the API kit installer. All of this software can be downloaded from the Intrepid’s web site at http://www.intrepidcs.com. Installation instructions can be found in Chapter 4.
Please refer to the Vehicle Spy documentation for its more specific PC hardware and operating system requirements and recommendations. Note, however, that Vehicle Spy will run on most modern Windows-based PCs.
