RC4000 Antenna Controller
3.6 Query Name Command
This query command instructs the RC4000 to send back to the host computer the name of a satellite
stored in non-volatile memory (via the controller's STORE mode) and the total number of satellites stored
in non-volatile memory. The command contains the index of the desired entry in the satellite list. A
maximum of 50 satellites can be stored in memory.
This query command contains 7 bytes and the format is:
byte 0
byte 1
byte 2
bytes 3,4
byte 5
byte 6
The response to this command contains 19 bytes and the format is:
byte 0
byte 1
byte 2
bytes 3,4
bytes 5,6
bytes 7-16
byte 17
byte 18
Note: If entry 'XX' does not exist in the list (or the list has no entries) the NAK reply will be sent back to
the host.

the query name command code
'XX'
where XX is the index of the satellite name being requested.
Normally this would be '01' the first time through and then
incremented until the 'YY' (YY being the last entry in the list)
satellite name is read. The maximum possible range for XX and
YY is 1 through 50.

'YY'
where YY is the total number of satellite names contained in the
list. Repeat this command YY times to download the names of
all stored satellites.
sat name
This field will contain the satellite name. The name will be in
capital letters and normally be left justified. The only time the
satellite name will not be left justified is if the user selected the
USER entry from STORE mode and manually entered blank
characters before the satellite name.
