Cruise control operation with the GPS-50-2
While a transmission or wheel based speed signal is ideal for operating a cruise control, the GPS-50-2 can be used when
this is not available. Special care must be taken in selecting the mounting location for the GPS-50-2 so that it can get a
clear view of the satellites. The difference in mounting locations is not noticeable for a speedometer, but can affect the
precision operation of a cruise control system. Try to locate the GPS-50-2 as high as possible. It can be under a
fiberglass or wood dash or in a headliner. Avoid having the unit surrounded by steel. Another alternative to get an ideal
GPS satellite signal is to use an external GPS antenna. This can connect to the OPTIONAL ANTENNA jack on the top of
the GPS-50-2 and be used instead of the internal antenna. The small, external antenna can then be mounted in a
location to get a clear view of the satellites with the GPS-50-2 hidden under the dash.
The
Snr
setup menu will aid in selecting an acceptable mounting location. This should be done in a clear, outside area
and not inside a building. Hold the switch beside the GPS-50-2 terminal strip while turning the key on. The display will
show the current revision code while this is held. Release the switch. Press and release the switch until “
snr
” is
displayed. Press and hold the switch until “ - ” is displayed. Press and release the switch until “
n
” is displayed. It should
be tracking at least 6 satellites. If it is less than this wait a few minutes for it pick up additional satellites. Press and
release the switch until “
H
” is displayed. The maximum signal strength will be displayed in real time. You should try
different locations to obtain a reading of
40H
or higher.
