TVC15 Installation Instructions |
|
Introduction The TVC15 Radio-Camera Interface will allow you to record the communications between the driver, pit crew and spotters with your in-car video camera. The ambient sounds in the car are also captured with a remote microphone. It works with all brands of race radios utilizing a standard 5-pin connector harness. Other models offer both IMSA and NASCAR helmet connectors. Imagine hearing all of the spotters' information, the pit crew's comments, and all of the driver's intended (and unintended) comments. The ambient sounds in the car will be clean, without all the wind noise common with many cameras' built-in microphones. Use your in-car video for sharing and for driver and crew improvement. Your in-car videos will sound so much better! Equipment Requirements
Installation Read this entire document before starting. The TVC15 box must not be located within 3 feet of the radio's transmitting antenna. It should be located in a place that will allow a crew member to turn the unit on and off, and to change the battery when needed. The TVC15 box may be attached to any secure part of the car, such as the roll cage, with a clamp or zip ties. It may also be attached to the floor of the car (behind the seat recommended) with Velcro. The external microphone should be mounted in an area of the car that is not subject to a lot of wind or air movement. We recommend placing the external microphone under the dashboard. Mount with Velcro or strong double-sided foam tape. If possible, wiring for the TVC15 should not be run parallel to other wiring in the car. Specifically avoid running TVC15 wiring next to main battery wires. All wiring should be secured with zip ties, Velcro wraps, or appropriate wire clamps. Connections from the TVC15 to the radio wiring harness and camera are shown on the drawing below.
Note: If you need to power both your in-car camera and your in-car radio from the car's battery, such as for 24- or 25-hour events, you may need to use an isolated DC to DC converter to power the camera when using the TVC15. This may be needed because if you power both the camera and radio from the same supply (car battery), you will be connecting the radio ground to the camera ground via the TVC15 and unless you use an isolated power supply for the camera, you will be creating a "ground loop" which acts as an antenna and can cause problems with both the radio and the camera. Sources for isolated DC to DC converters are available from I/O Port Racing Supplies. Setup and Testing
