If the command cannot be executed, the RC1000A response will be ...
byte 0 : NAK
byte 1 : 'AA' where AA is the RC1000A address
byte 2 : '35h' the query command code
byte 3 : ETX
byte 4 : 'chksum' the checksum
AUTO COMMAND
This command specifies that the controller move the antenna to a
satellite. The command contains 13 bytes. Here is the format ...
byte 0 : STX
byte 1 : 'AA' where AA is the RC1000A address
byte 2 : '32h' the command code
byte 3 polarization This field can specify 'H', 'V'
or ' ' (blank). If this field contains a blank
there is no polarization adjustment. If this
field contains 'H' or 'V' the polarotor is
driven to the satellite's preset horizontal or

byte 4-10 sat_name This field specifies the satellite
name. The sat_name should be in capital
letters and left justified within this field.
If necessary, the name can be padded with
blanks to fill the entire field.
byte 11 : ETX
byte 12 : 'chksum' the checksum
The reply to this command will be the same as the reply to the QUERY
command except that the command code field will be '32h'.
AZIMUTH JOG COMMAND
This command jogs the antenna in azimuth. The command contains 11
bytes. Here is the format of the command
byte 0 : STX
byte 1 : 'AA' where AA is the RC1000A address
byte 2 : '33h' the command code
byte 3 : direction This field can specify 'E', 'W', or
'X'. 'E' refers to east and 'W' to
west. An 'X' specifies that the
antenna stop moving.
byte 4 : speed This field specifies the jog speed,
either 'F' (Fast) or 'S' (Slow).
Note that this field must contain a
