APPENDIX II. DORIAN TRANSPONDER & RFID.
1. Each Competitor will be required to fit a Dorian Electronic Self Identification Module to their Car/s for the purposes of accurate timing. Only one of the following systems is permitted to be used at this Event: The Dorian TX16 k multi DDL unit or the Dorian DATA-1 Automatic Driver ID System.
2. Holders for these and detailed fitting instructions will be issued with the transponders and it will be the responsibility of the Competitor to fit these in the Car in the position and manner specified. The Modules must be in place and functioning correctly for all Sessions. The setting and servicing of these items must only be carried out by properly authorised licensed Timekeepers.
3. The other component is the RFID receiver in the cabin of the Car, and the RFID chip which is placed on the Driver’s helmet communications connector. The RFID receiver detects the unique code of each Driver whilst they are in the Car with their headset cable connected to the Car’s communications radio system. It is the Competitor’s responsibility to ensure that these are used correctly and that the Driver in the Car is shown correctly on the timing screens for every session during the Event. If an incorrect Driver ID is recorded at pit entry or pit exit, a penalty may be imposed by the Stewards.
4. To ensure that the proper Driver is shown at all times, the Driver ID must not be changed before the Car is stationary and must be correctly changed before the Car crosses the pit exit timing loop.
5. Competitors may not place electronic timing equipment within five metres of the official Start and/or Finish Line or any other official timing lines at any Event or test session/day. Any such equipment placed within these zones will be removed.

Dorian Data Transmitter
1. The Dorian DATA-1 transmitter must be mounted under the Car, no higher than 350 mm, with no metal or carbon fibre between the transmitter and the race track surface. The orientation is also important, it must be mounted longitudinal along the length of the Car. There must not be any metal or carbon fibre directly in front or behind the transmitter, a clearance of 10 cm is desirable.
2. Below are the Dorian Industries Recommended Mounting arrangements, although the drawings indicate 400mm max height, for GT Cars with full carbon under trays the recommended max height is 350 mm.
Automatic RFID Receiver
1. The RFID receiver is mounted in the Driver’s cabin with the NEXIS TJ-101 radio connecter mounted in the centre of the RFID receiver, the maximum outer diameter of the connector cannot exceed 16mm.
2. The NEXIS TP-120B connector on the cable from the helmet kit has a small RFID device attached to the side of the casing. When the helmet plug is inserted into the NEXIS socket, the code identifying the Driver is transferred to the Dorian DATA-1 transmitter and then to the timing and scoring system.
3. The location of the RFID chip on the helmet plug is critical; it needs to be mounted as close to the shoulder of the connector as is practically possible with no metal around the chip. When the helmet plug is inserted correctly the front of the chip must be within 2mm of the front edge of the receptacle.
2022 Liqui-Moly Bathurst 12 Hour Sporting & Technical Regulations DRAFT Page 45 of 58 Round 1 of the 2022 Intercontinental GT Challenge © Supercars Australia
If a quick pull system with dry-break fluid fittings is used, the chip must not be fully or even partially covered by metal. A number of organisations manufacture mountings to carry the helmet plug and a dry-break fluid fitting together, two are shown below.
1. Garry Rogers Motorsport manufacture a system made from plastic, so far there have been no issues with these fittings, the RFID chip is mounted in a slot moulded into the plastic around the NEXUS connector. (See picture below)
2. Ash Seward distributes a system manufactured from aluminium by Force Accessories, there has been an issue with some of these, however there is a simple fix. On the adapter plate, If the dimension of the offset between the mounting holes for the dry-break connector and the RFID receiver mounting holes is increased to 12-13mm it allows the helmet radio plug to protrude 14mm from the aluminium quick pull housing, this then has enough space to mount the RFID chip in front of the housing. (See picture below)
2022 Liqui-Moly Bathurst 12 Hour Sporting & Technical Regulations DRAFT Page 46 of 58 Round 1 of the 2022 Intercontinental GT Challenge © Supercars Australia
3. There are other manufacturers of Quick Pull Multi Holders, however they are all very similar to the two shown above. The important thing to remember when setting up and installing these devices is that the RFID chip needs to be within the funnel of the RFID receiver without any metal around the RFID chip.
