4.5.8 Signal
Selection
This command reads the MUX timing outputs available on the rear panel.
Rrsn
rrsn #
where # =
1 for 1.544 MHz outputs.
2
for
2.048
MHz
outputs.
3 for a 1.544 MHz and a 2.048 MHz output.
0 for all other configurations.
4.5.9 Short
Status
This command gives a
Short Status
string. The controller can read this status
information for alarm conditions. This command would generally be issued after the
controller has polled the unit using the Alarm Status command.
rsts
rstsSDDDHHMMSSDDDHHMMSSDDDHHMMSSSDD.D32TFFCsssAO1BNL where S
= number of satellites ( If tracking satellite is greater than 8, it will be truncated to 8),
DDD= days remaining T1, HHMMSS= time remaining T1, DDD= days remaining T3,
HHMMSS= time remaining T3, DDD= days remaining T2, HHMMSS= time remaining
T2, SDD.D= internal temperature, 3=y or n for T3 timed out, 2(y/n)= T2 timed out,
T(y/n)= test mode, F(y/n)= free run, F(y/n)= Frequency alarm (oscillator failure), C(y/n)=
cpu alarm, sss = three major alarm spares, A(y/n)= oscillator adjust, O(y/n)= output
fault, 1(y/n)=T1 time out, B(y/n)= replace battery, N(y/n)= antenna problem, L(y/n)= low
GPS quality.
4.5.10 Time And Date
This command is to read the
Date and Time
. The leading character of the
RS-485 protocol message is the “on-time” point.
rtad
rtadHHMMSSsHHMMDDMMYYYY
where HH = hours 00 to 23, MM = minutes, SS =
seconds, s = sign of Time Zone offset, HHMM = hours and minutes of Time Zone offset,
DD = days, MM = months, and YYYY = year.
