byte_24_25_position ... is the
value returned in bytes 24 and
25.
user_interface_position ... is
the polarization position
displayed on the display of the
user interface.
Note that the division defined
above is an integer division.
The result is rounded DOWN to
the closest integer.
Please see byte 32 of this
command's reply message for more
information on polarization
position representations.
byte 26 : polarization code and autopol status -
binary data

byte 27 : azimuth movement/alarm status - binary
data

0 0 0 0 no alarms or movement
0 0 1 0 ccw movement pending

0 1 0 0 ccw movement in progress
0 1 0 1 cw movement in progress
0 1 1 1 an auto move is in progress
1 0 0 0 runaway alarm active
1 0 0 1 jammed alarm active
1 1 0 0 drive alarm active. This is
triggered by an overcurrent
condition.
Note - Higher value status codes have priority over
lower value ones, i.e if as part of an auto move
command the antenna is moving cw the status will be
reported as 'auto move in progress' rather than 'cw
