GPSTIME {OFF|VALID|ON} {GGA|GLL|RMC|ZDA }
default VALID RMC
This command specifies how the KAM’98 clock will be set from a GPS device.
If GPSTIME is set to OFF, the KAM’98 software clock is not set when NMEA
strings are received. If GPSTIME is set to VALID, the clock is set, if and only if
the valid bit in the string specified is set.
If GPSTIME is set to ON, the time is acquired from the string specified.
Note: In any event, any string must have a valid checksum. Second, time is not up-
dated if the time received in a string is the same as the last time received. Third,
GGA and GLL strings do not include a date; the ZDA string does not include a
“valid bit:” and some units do not include a valid bit with the GLL string.
GTDOWN n (n = 2 - 30)
default 6
Sets the number of consecutive bad frames received before switching to the next
lower baud rate (G-TOR baud rates supported are 300, 200 and 100).
GTERRS n (n = 30 - 255)
default 40
Sets the time-out attempts for G-TOR. When attempting to link with another sta-
tion, the unit times out after n attempts without a response. When already linked,
reception of n consecutive faulty frames results in a timeout.
GTFUZZY n (n = 0 - 3)
default 3
Sets the number of bits in a data acknowledgement that may be corrupted.
