5)
Make sure the vehicle has a clear view of the sky. Allow the RPR 100
G
about 15
minutes to acquire all of the satellite information.
Initial start-up
Both the internal GPS and WAAS receiver must perform a “cold start” the first time the system is
powered up. The GPS receiver will search the sky for satellites and download data necessary for
operation. The WAAS receiver will wait until the required almanac data is received. The cold start will
take up to 15 minutes but is only required during the initial power up. Connect the serial cable
provided between the RPR 100
G
and the computer and apply power. Turn off all unnecessary elec-
trical equipment to minimize electrical noise interference. Upon completion of the initial “cold start
,
”
the receiver begins to operate in “normal mode
.
” The unit should be operating in full DGPS mode
within a few minutes of power up, after the almanac has been established during the cold start.
All configuration and WAAS data is stored in nonvolatile memory inside the RPR 100
G
. Configuration
changes are made with
terminal emulation
software.
NOTE:
Be aware of possible satellite obstructions, which may interfere with GPS operation.
6)
Plug in the receiver’s 9 pin connector to the data logging device. Note that you may
have to contact the vendor of your hardware for any specific cable needs to adapt to
the 9 pin RS232 connector. The settings for the data stream are GGA and VTG at
4
Hz
and a baud rate of
19,2
00 bps.
7)
If using a Raven controller, attach the speed connector to the rear of the console,
program the console in SP2 and put in a SPEED CAL number of 785.
NOTE:
If using a non-Raven controller, an adapter cable will be required.
