    Old Technology
    With the 1914 introduction of the glass fuse for automobiles and later the introduction of electronic relays and solenoids for high current switching and it becomes obvious that little has changed in a century. Through a mechanical action (burning of a fuse, switching of a relay) electronic devices are switched of and on in a vehicle.

    Given the advancements in electronic technology, it was only a matter of time before the use of solid state technology would replace the burning of a fuse or switching of an electronic relay to control electronic devices in a vehicle. The modern day street car now utilizes a variety of power control modules to handle device activation in street vehicles. From something as simple as door locks activated when the vehicle is placed in drive (and the doors are closed) to airbag activation triggered but only if deceleration forces are beyond a given level, when the vehicle is moving are all accomplished through a programmable power module.

    New Technology
    The Racepak SmartWire is a fully programmable power distribution module, capable of controlling 30 outputs (on / off switching) and 12 inputs (switch activated) on any type of 12 – 16 VAC systems. Fuses, relays and solenoids are eliminated, instead controlled through solid state switching inside the housing. Current outputs, switching inputs along with a nearly unlimited variety of and/or on-off switching functions are user programmable through the DatalinkII software.

    How Does it Work?
    In the most basic form, the SmartWire is installed between the vehicle battery and the devices which will be turned off and on. Everyone has heard of transistors. This little invention allowed us to carry our radios with us, calculate numbers and eventually read this on your computer. Transistors function as tiny switches, moving a greater amount of current than required to switch it. Next, came the FET, moving voltage. Through the use of the FET technology, the SmartWire can switch and control current and voltage without the use of any mechanical devices. It is all handled through the solid state board inside the SmartWire housing.

    Operating Modes
    One SmartWire unit can operate in three different modes:

    1. Stand Alone: Power from the battery is connected to the power stud of the SmartWire. Output to each device in the vehicle (fans, pumps, etc) are connected to one of two 15 pin connectors. Output currents and related requirements are programmed via connection of the SmartWire unit to the users PC. Switching off and on of the devices is handled through inputs on the 15 pin connectors or optional SwitchPanel or SwitchModule.

    2. In conjunction with Racepak V-Net sensors: Want to automatically turn on a radiator fan, but only when the water temperature is above 190 degrees? Add a Racepak V-Net water temperature sensor to the vehicle, connect it to the V-Net port of the SmartWire and program through use of a PC connected to the SmartWire. What if you need to add a second requirement to trigger the radiator fan, such as water temperature above 190 degrees AND fuel pressure above 10 psi? Just add a V-Net fuel pressure sensor and module to the existing V-Net cable which is already transmitting the water temperature data and program accordingly.

    3. In conjunction with a Racepak V-Net data logger: This allows the SmartWire to be connected to the single V-Net T cable which transmits all sensor data to the data logger. The SmartWire “borrows” the sensor data to trigger devices based on desired programmed settings. In addition, all states and conditions of each channel can now be monitored and recorded in the DatalinkIIsoftware, alongside all the other sensor data.

    As seen, the SmartWire is the most advanced, cost effective method to not only clean up a vehicles wiring, but allow near unlimited on-off programming capabilities to vehicles devices.
