POWERPAK II INSTALLATION
Using the PowerPak II is straightforward. A minimum configuration (Figure 14 Typical PowerPak II Installation
Configuration) is established with the following set-up:
1. Set up the GPSAntenna.
2. Route and connect the RF coaxial cable between the GPSAntenna and PowerPak II. High quality coaxial cable
should be used because a mismatch in impedance, possible with lower quality cable, produces reflections in
the cable that increases signal loss.
3. Connect a RS232C communication interface to one of the serial ports of the PowerPak II.
4. Supply power to the input power jack of the PowerPak II.
See Antenna, Page 14 for further information on installation of the GPSAntenna and coaxial cable.
