TelemetrySystem / Introduction

Introduction

The articles in this section give an overview of the Telemetry System and the configuration software used by the system. The Telemetry System is used to monitor information sent by a Race Technology product that is placed at a remote location. For example, the DL1 may be fixed on a vehicle and will transmit data to a stationery observer for remote monitoring. The Telemetry System comprises if the following components:

• Radio Transmitter device (attached to a “data source”, for example a DL1 data logger)
  The Radio Transmitter filters incoming serial messages and transmits them to a Radio Receiver
• Radio Receiver device (attached to a “data display or recorder”, for example PC running monitor software or dashboard)
  The Radio Receiver device will receive data sent by a Radio Transmitter device. The Radio Receiver will then retransmit the received data over its serial interface. The user can connect the Radio Receiver to a PC via a serial cable and view the data.
• Configuration software
  A software tool used to configure the Radio Transmitter and Radio Receiver devices.

The following diagrams illustrate a basic system

Whilst the “useful” data transfer is from the Radio Transmitter to the 'Radio Receiver , in reality the data transfer is 2 directional as every packet that sent to the receiver is checked and confirmation is sent back to the Radio Transmitter'' that it was received and was error free. If the number of errors passes a threshold then the telemetry system will vary its transmission rate and channels to optimise the speed of the link.
