To select GARMIN input/output...
· Place the cursor on the input/output format field.
· Press CLR until the GARMIN input/output option is selected.
· Press the right arrow key.
· Select “Host”, “Req[uest]”, or “Send” by pressing CLR. (NOTE: You
should select the “Host” option when using the GPS 95 with a PC.
When exchanging data between two GPS 95s, one should be set to
“Host” and the second should be set to the desired data transfer option
- “Req[uest]” or “Send”.)
The GPS 95 can use Differential GPS
(DGPS) corrections in RTCM SC-104
version 2.0 format. DGPS corrections
in this format can be received from an
external device (capable of output in 6
to 8 byte format as specified by RTCM
SC-104 version 2.0) by connecting the
device to the input port on the back of
the GPS 95 and selecting an RTCM input interface mode. Two RTCM input
modes are available; one which allows no output and another which allows
NMEA output in 0180, 0182, or 0183 format.
To select an RTCM input...
· Place the cursor on the input format field.
· Press CLR until the desired RTCM input option (RTCM/NONE or
RTCM/NMEA) is displayed.
· Press the right arrow key.
· If RTCM/NONE is selected: Press CLR to select the appropriate baud
rate.
· If RTCM/NMEA is selected: Press CLR to select the desired NMEA
output format. (NOTE: With RTCM/NMEA selected the RTCM baud
rate is automatically set to 1200 or 4800.)
If the RTCM input is selected, but the GPS 95 is not connected to an RTCM
device, the unit will alert you with the message “No RTCM Input”. If the GPS
95 does not receive sufficient data to compute a DGPS-corrected position,
the message “No DGPS Position” will appear.
