Interface Data Unit (IDU)


IDU front view

The Interface Data Unit (IDU) acts as the central data management junction between the computer, Decoders, and additional devices. It coordinates both incoming and outgoing signals to and from the computer, synchronizing data for the entire system. The IDU receives information from the decoders via the RaceBus Link. It then coordinates, and transmits this data via the RS-232 to the computer for further analysis. This information is compiled at the computer and sent through the IDU to devices such as scoreboards, driver results printers, GRIDMaster hand-held controllers and third party devices. Linking the entire system to one computer centralizes operations and reduces confusion caused by using numerous information centers or multiple event personnel attempting to coordinate operations manually.

Specifications
Dimensions: 11" x 8" x 2.5" (~ 22 x 16 x 8 cm)
Interface to PC: RS232
Power Supply: Universal AC (90 - 260V) auto detect
Multiple Decoders: Yes

Decoders

The Decoder determines the crossing time and reads the unique identification number of the transmitter on each vehicle as the vehicle passes over the Loop Antenna. The Decoder then sends the crossing information to the InDoor Unit via the RaceBus Link. Each Decoder may be connected to a Loop Antenna 30 feet (recommended) in width. To cover wider tracks, multiple Decoders and Loop Antennas are generally chained together. Multiple Decoders are also used to track split times and pit row activity. Decoders can easily be added to the Race Management System as desired. This makes for a simple scalable system that fits different budgets and different tracks.

100-200 feet using IDU to provide power to Decoder
500+ feet using localized power or boosters for Decoder
Indefinite distances with repeaters

Rechargeable Transmitter


The transmitters are light, compact devices attached to each vehicle. Each transmitter is assigned a unique identification number to differentiate individual vehicles. As the vehicle passes over the Loop Antenna, the Decoder reads this identification number and determines a crossing time. The information is then sent digitally via the RaceBus to the IDU.

The transmitters have convenient LED indicators for operational status. A green LED indicates the transmitter is working. A red LED indicates a low battery condition. There is no guesswork involved in determining battery status. During a race the transmitter is also capable of relaying a low battery status to the Race Management System and informing the system operator of this condition.

Specifications:
Dimensions: Approx. 3" x 2 x 1" (~ 7.62 x 5.2 x 2.55cm)
Weight: Approx. 4oz (100 grams)
Temp Range: 32-122° F (0-50° C)
Battery Life: 7 Days
Charge Time: 3 Hours
Operational Indicator: LED
Low Battery Indicator: LED
Humidity: 90% Relative

Hardwire Transmitter
The hardwire transmitters are light, compact devices powered by the vehicle's own power supply. Hook this up to your vehicle and forget worrying about whether you charged up the transmitter. Each transmitter is assigned a unique identification number to differentiate individual vehicles. As the vehicle passes over the Loop Antenna, the Decoder reads this identification number and determines a crossing time. The information is then sent digitally via the RaceBus to the IDU.

The transmitters have convenient LED indicators for operational status. A green LED indicates the transmitter is working. A red LED indicates a low voltage condition. There is no guesswork involved in determining whether the transmitter was installed correctly.

Specifications:
Dimensions: Approx. 3" x 2 x 1" (~ 7.62 x 5.2 x 2.55cm)
Weight: Approx. 4oz (100 grams)
Temp Range: 32-122° F (0-50° C)
Voltage Requirement: 9-14 Volts
Current Draw: < 30 milliamps
