command is sent, both ports will be refreshed. This
may result in a small amount of data loss during the brief rate change.
5.6.2.3 Tune Command ($PSLIB)
A majority of Garmin hand-held and fixed-mount GPS receivers output
this non-standard command from the BEACON RCVR feature of the
INTERFACE menu. It instructs the connected SBX-3 to tune to the
specified frequency and MSK Rate. The command has the following
form:
$PSLIB,fff.f,ddd<CR><LF>
Response:
N/A
In this message, fff.f is the frequency in kHz (283.5-325 kHz; 0 - Auto).
The ddd field represents the desired MSK bit rate in bits per second
(100, 200 bps; 0 - Auto).
5.7 NMEA 0183 Queries
This section discusses the standard and proprietary NMEA 0183
queries accepted by the SBX-3.
It is important to note that when issued to the SBX-3 primary
communications port, the response messages will be output
interspersed with RTCM correction information. This may cause
conflicts with a GPS receiver’s ability to compute differential corrected
solutions. To avoid this potential conflict, Section 3.5 describes the use
of the SBX-3 secondary communication port for performance and
configuration status querying and reporting.
