Global Positioning System (GPS) Device (Not Included)
Your Cobra Marine radio does not include a built-in GPS receiver. After connecting an
external GPS receiver, your position will be continuously indicated on the LCD and,
most importantly, it will be included automatically with any DSC Distress message you
may need to send. That will take the “search” out of “search and rescue.
An external GPS input connector has been provided to allow connection to a
back-up GPS receiver.
To Install A GPS Device:
1. Install the GPS device in a convenient location according to its manufacturer’s
directions.
2. Plug-in the optional Cobra C.P.S. (Cobra Positioning System) into the provided
2.5mm jack.
3. Or using the supplied 2-wire adapter wire as follows:
Yellow wire - NMEA 0183 +Data in
Green wire - NMEA 0183 -Data in.
NOTE
Satellite acquisition time is dependent on the antenna mounting location. If the
acquisition takes too long, relocate the radio or use an external GPS receiver.
NOTE
GPS data input is as follows:
Input voltage (peak to peak): 10V
Maximum data rate: 4800 baud
• Impedance: 4KΩ
