SYSTEM INSTALLATION
INSTALLING THE RECEIVER
Because of its compact size and light weight, you have lots of flexibility in how and where you install
your Magnavox DGPS 12 Channel Receiver. An adjustable mounting platform lets you mount the
unit in any orientation, even on the overhead. To ensure a precise installation, each unit comes with
an installation template.
You will want to choose both a physically safe environment and an eleetromagnetically safe
environment.
Choosing a Safe Physical Environment
Locate an installation site away from excessive heat sources, such as heating vents or
equipment heat exhausts. Also avoid sites (examples would be port holes/windows and
hatches that open to the outside) where the How of humid salt air might corrode intemal
components.
Despite the sturdiness of the Magnavox receiver, don’t subject it to hard, continuous
vibration. If you think excess vibration is a problem, order the vibration isolation kit (P/N:
B19807-801)
Allowing for Progr Distances
Give some thought to the location of the unit. You may wish to visually monitor the three
status indicators (red, yellow and green LEDs, willed traffic lights) on the front panel while
working with other equipment. If you intend to monitor the receiver with a personal
computer, you’ll want to view the screen while at a particular location. A careful choice of
receiver location will minimize cable lengths between components. For Navigators, you’ll
also want to allow a safe distance from the receiver to the navigation compass to minimize
compass deviation. Refer to Table 3 as your guide.

Allowing Access to Rear Panel
You will want access to the ANTENNA input connector, the 1 PPS output connector
(perhaps), and the MULTI-PORT Interface DB 25S connector (Figure 4).
Note: The 1 PPS (1 pulse per second) output connector provides an optonal timing source;
the 1·second timing pulses are accompanied by an ASCII message giving you the precise time
of each pulse.
