8.7.5.6 TSC (Terminal Status Change)
Use the TSC query to determine if the status of the terminal has changed since it
was last polled. If any of the parameters listed in the RCS or RUS queries have
changed as a result of user front panel operations or remote operations, or if any
new fault conditions occur, the TSC command returns YES. The TSC query then
continues to return YES until any of the following queries are received: RCS, RUS,
RAS, PACRCS, PACRUS, or PACRAS.
>DEV/TSC_nnn{cr}{lf}] where:
nnn=YES/NO
8.7.5.7 PACRCS (Packed Configuration Status)
>DEV/PACRCS_aaaaaaabbbcdeffgghijkl{cr}{lf}] where:
aaaaa or aaaaaa = # of steps above base frequency
1
bbb = # of 0.25 dB steps above 0.00 dB
2
c = 1 if Transmitter ON, 0 if OFF, 2 if Cold
d = 1 if unit ONLINE, 0 if OFFLINE
e = 1 if Redundancy ON, else 0
ff = converter # (01-12, BU or 00 if e = 0)
gg = 00 if 'ff' is 00 (redundancy OFF)
g = chain length (01-12) if 'ff' is BU
gg = XX if 'ff' = 01 - 12
h = A if Auto Mode, M if Manual

I = 1 if Cold Start Enabled, else 0
j = 1 if Auto recovery enabled, else 0
k = 1 if an Ext. Ref is present, else 0
l = 1 if Remote Mode, 0 if Local Mode
1) If frequency selection is optional 1 kHz step size, the number of 1
kHz steps above the base frequency is 7 bytes in length (aaaaaaa).
For DT-4513X converters with 125 kHz frequency step size, the
number of 125 kHz steps above the base frequency is 5 bytes in
length (aaaaa).
2) If the attenuation is optional 0.1 dB step size, this is the number of
0.1 dB steps above the base frequency
3) If the converter is a backup converter, it is always ‘A’.
