Appendix C– DTR Remote M&C Protocol CG-6073 (Rev R, June, 2012)

3.3 Status Requests
Status requests are obtained by polling the DTR for information. All status requests
send by default only the information that has changed since the last request. Each
request has an option to force transmission of all status information.
The recommended operating procedure for the remote computer is to get a full
status update when the M&C software is launched, then periodically get status
updates.
Status commands return their data as a string which may be parsed into one or
more fields. A field contains data which is logically grouped together. A field may
have sub-fields. An example of this is found in the S command in the “Monitor and
Control Commands” Section. This keyword requests receiver status; the response
is formatted with character separators for each field and fixed field widths as
follows:
BbbCcEeeFffffffffVvvvvAaaaIi
Where B = beacon, C = control, E = errors, D = frequency, V = voltage, A =
attenuation, and I = RF input.
Sample:
>S
B00C0E00F01014000V0108A000I1
While the total length of a status update depends on the number of fields that have
changed, the length of any data field (that is, a field without sub-fields) is always
fixed.
