Note 2: At the next power up, the ALLSTAR will align its
TIMEMARK pulse and GPS measurements on GPS
time.
Note 3: Value is between 0.0 and 90.0 degrees.
Note 4: 0 to 255 seconds.
Note 5: Valid baud rate: 0.3, 0.6, 1.2, 2.4, 4.8, 9.6, 19.2 (in
kBaud units).
Note 6: Will be stored in NVM.
Note 7: This number indicates how many parameters are
listed in the messages. Shall be 15.
Note 8: This parameter controls the number of digits that will
be transmitted for the fraction part of the latitude and
longitude data in all NMEA messages. The default
value is 4 and the range is 0 to 5.
Note 9: This parameter controls the number of digits that will
be transmitted for the fraction part of the UTC time
data in all NMEA messages. The default value is 2 and
the range is 0 to 9.
Note 10: This parameter is used to specify the datum that shall
be used to express the position. Refer to the supported
datum list (i.e., 0 = WGS 1984).
Note 11: DGPS mode:
E = enable Beacon/WAAS autoD = disable DGPS
W = enable WAAS only B = enable Beacon only
Each of the parameters (except the number of elements) may
be NULL, the associated receiver parameter will be left
unchanged.
