Connecting external sensors to the DL1 SPORT
Connecting GPS
For the DL1, the GPS antenna comes with 3 metre cable, which will allow you to position the module almost anywhere on a road car. The GPS antenna connects via a co-axial screw connector on the back of the DL1 Unit. Once the GPS antenna has been connected, it will turn on automatically when there is power to the DL1 unit.
The best place to position the GPS antenna will change depending on the vehicle type. The GPS needs a good clear view of the sky to be able to lock onto the satellites to give the best results. As such, if there is a roof to the vehicle, this will always be the best place to place the antenna. If you are on a vehicle like a kart or a bike, then you will have to find the best location which gives a constant view of the sky.

"WARNING": To avoid any possible damage to the car paintwork, please take care when mounting magnetic GPS antennas. In particular make sure that there are no dust or grit under the antenna. In some cases it maybe required to add additional protection to the paintwork prior to mounting the antenna to avoid damage.
External Sensors
The DL1 SPORT allows you to attach several external sensors for logging. There are 8 analogue channels (12v input), for each input, the positive wire connects to the input, and the ground to one of the ground connectors. If the sensor needs a 5v reference supply, one of the pins on the analogue connector side supplies this. You can have more than one sensor attached to the ground and reference output.
If you wish to connect an RPM sensor, see here for more details.
The 12v input is a nominal maximum which the channels are calibrated for, the absolute maximum is about 50% higher. Exceeding this upper voltage limit will cause other channels to read incorrect voltages.
Remote control for GoPro camera
The DL1 SPORT has can be connected to a GoPro camera to provide remote control to stop and start the camera automatically when the data logger starts. Please contact Race Technology for details of the cable and license required for this.
