17 - The az/el/pol display offsets or sensor direction flags are
corrupted.
18 - The polarization equipment code or polarization auto move
parameters are corrupted.
19 - Antenna polarization alarm detected.
20 - The azimuth and/or elevation auto move parameters or the
simultaneous az/el flag is corrupted. On versions of the
controller designed to interface with the Harris 9135 outdoor
enclosure this alarm code will be asserted if the azimuth and/or
elevation slow speed parameters are corrupted.

byte 37:

Track Mode submode or error status and track frequency band - binary data

7 6 5 4 3 2 1 0

0 1 B B $ S S S S

where ‘BB’ is ...
00 - C band
01 - Ku band
11 - L band

and where ‘SSSS’ is ...
0000 - track mode not active
0001 - track setup submode active
0010 - track auto mode entry
0011 - step track submode active
0100 - track auto search submode active
0101 - program track submode active
0110 - track manual search submode active
1000 - track jammed error
1001 - track limit error
1010 - track drive error
1011 - track peak limit error
1100 - track geo position error
1101 - track system error track
1110 - track checksum error

bytes 38 - 41:

AGC Channel 1 The AGC channel 1 voltage is represented internally by a

numeric value between 0 and 1023. This numeric value is
converted to an ASCII string - ‘ 0’ and ‘1023’. The most
significant digit will be placed in byte 38 and the least significant
digit will be placed in byte 41. The string will be right justified
and padded with blanks (on the left).

bytes 42 - 45:

AGC Channel 2 The AGC channel 2 voltage is represented internally by a

numeric value between 0 and 1023. This numeric value is
converted to an ASCII string - ‘ 0’ and ‘1023’. The most
significant digit will be placed in byte 42 and the least significant
digit will be placed in byte 45. The string will be right justified
and padded with blanks (on the left).

bytes 46 - 49:

Reserved - At this time these bytes are initialized to 0100$0000b.

byte 50:

ETX

byte 51:

checksum

Query Name Command

This query command instructs the RC2500 to send back to the host computer the name of a satellite

stored in non-volatile memory (via the controller’s SETUP mode) and the total number of satellites stored
