Vnet Smart Sensor System

What is Vnet? This Racepak exclusive provides the ability to transmit the data from up to 12 sensors, through a single cable connected to the AUX port of the G2X. Think of the Vnet much the same as a power strip. The power strip receives electricity from a single cable, plugged into an outlet. A shop light and grinder are plugged directly to the power strip, while your drill press requires a 10’ extension cord. In much the same manner, the G2X can both power and receive data from multiple sensors, all through the Vnet cable. If a Vnet sensor and module are out of reach of the main G2X Vnet cable a Vnet extension cable is utilized to connect to the cable.

What are Vnet Modules and smart sensors? In order to utilize the Vnet cable, each sensor is accompanied by a Vnet Module. This Vnet module contains scaling and calibration values along with channel name and other sensor specific information, which then creates a smart sensor. This technology allows the user to install sensors into the G2X package, connect their PC to the G2X and instruct the DatalinkII software to “Read” the system. This procedure automatically adds the sensor to the software and hardware of the G2X. Each Vnet module is equipped with a male / female connector. This design allows the modules to be connected back to back. In the event that Vnet modules and sensors are mounted some distance apart, simply connect each Vnet module with a Vnet extension cable.

Why would I add a Racepak gauge? In much the same manner as described above, gauges can also be added to the Vnet system. For example, the user installs a Vnet oil pressure sensor. To add a Racepak oil pressure gauge to the system, simply install the gauge in the desired location in the vehicle. The gauge is then connected into the Vnet cable by means of Gauge Tee Cable. The gauge then “borrows” the data from the Vnet oil pressure sensor and activates the gauge, while transmitting the oil pressure sensor data to the G2X, for data logging purposes. Multiple gauges are connected by means of a Gauge to Gauge cable with the last gauge in line connected to the G2X Vnet cable by means of a Gauge Tee Cable.

What does all this mean to me?

• By utilizing the Datalink “Read” command, sensors are automatically added to the DatalinkII software.
• Up to 12 sensors and gauges may be installed in any order on the vehicle.
• Eliminates the necessity of routing multiple wires to each sensor
• Eliminates the necessity of double sensors when utilizing Racepak gauges
• Eliminates the confusing procedures of user setup and calibration
• Reduced weight due to elimination of wiring
• It’s just easier
