2.1.4Choosing a Coaxial Cable

An appropriate coaxial cable is one that matches the impedance of the antenna and receiver being used (50 ohms), and whose line loss does not exceed 10.0 dB. If the limit is exceeded, excessive signal degradation occurs and the receiver may not be able to meet its performance specifications. NovAtel offers a variety of coaxial cables to meet your GNSS antenna interconnection requirements, including:

•5, 15, or 30 m antenna cables with TNC male connectors on both ends (NovAtel part numbers C006, C016 and C032 respectively)

Your local NovAtel dealer can advise you about your specific configuration. If your application requires the use of cable longer than 30 m, refer to the application note RF Equipment Selection and Installation on our website at www.novatel.com, or you can obtain it directly from NovAtel.

High-quality coaxial cables should be used because a mismatch in impedance, possible with lower quality cable, produces reflections in the cable that increase signal loss. Though it is possible to use other high-quality antenna cables, the performance specifications of the OEMV family receivers are warranted only when used with NovAtel-supplied accessories.

2.1.5Power Supply Requirements

This section contains information on the requirements for the input power to the receiver. See Appendix A, Technical Specifications starting on Page 72 for more power supply specifications.

WARNING: If the voltage supplied is below the minimum specification, the receiver will suspend operation. If the voltage supplied is above the maximum specification, the receiver may be permanently damaged, voiding your warranty.

The DL-V3 enclosure is supplied with a 12V power adapter with a built-in 3 A slow-blow fuse for use with a standard 12 V DC power outlet. You can choose to press the DL-V3 power button or wait for the power sequence, when it monitors the serial ports, as long as a valid voltage is present at the power supply input, see DL-V3 Power Down and the Power Button on Page 33.
