Status Mode Commands
Return Status of Event/Deviation
Command:
SA
SA returns the event/deviation channel setup information, read index number and write index number.
Response: D(E), R = nn, S = mm
C
Format:
D indicates the input channel is in 1 PPS deviation mode
E indicates the input channel is in event mode
nn Channel read index (01 to 50)
mm Channel write index (01 to 50)
NOTE: When nn = mm, using the EA command to read event data, the event buffer is empty, i.e., all event
data which has been recorded has also been read.
Return Clock Status
Command:
SC
SC returns the current clock status.
Response: L/U, U=xx, S=nn
C
Format:
L = Clock currently locked to GNSS (U for unlocked).
xx = Indicates loss of lock period, up to 99 minutes.
nn = User specified out-of-lock delay, 00 to 99 minutes (refer to Table A-8).
S = Off if the out-of-lock function is deactivated, S = ZDL indicates zero delay.
Return DCXO Status
Command:
SD
SD returns the DCXO (Digitally Compensated Crystal Oscillator) status, which compares the oscillator with
the 1 PPS to track the oscillator drift.
Response:
±
pp.pp PPM
C
Format:
pp.pp = Residual, corrected DCXO error, in parts per million
EEPROM Status
Command:
SE
SE returns the EEPROM status.
Response: T=t CE=ee
Format:
t = 0, No Timeout Error; t = 1, Timeout Error
ee = Number of corrected errors in reading EEPROM data
