The BU register indicates if the motor and thereby also the mast is currently moving.
For mechanical reasons, the motor cannot start immediately after the receipt of a start
command.
Therefore it is necessary to wait until the mast moves (BU = 1), before it is possible to
enquire with BU whether the previous command has been completed. If the mast is already
located in the desired position when a GO command is received, BU will nevertheless be set
on 1 for approx. 0.5 sec.
Commands to Load the Registers
LD nnn CM - Load the value nnn into the register following.
Commands to Control the Mast
UP - Moves the mast basket up until the upper limit is reached or a STOP
command (ST) is received.
DN - Moves the mast basket down until the lower limit is reached or a STOP
command (ST) is received.
GO - Moves the mast basket to the position, which is in the set point register (NP).
P? - Current polarization of the antenna.
0: Horizontal polarisation
1: Vertical polarisation
PV - Sets the antenna to vertical polarization.
PH - Sets the antenna to horizontal polarization.
Commands to Control the AS
P? - Current polarization of the antenna.
0: Horizontal polarisation
1: Vertical polarisation
PV - Sets the antenna to vertical polarization.
PH - Sets the antenna to horizontal polarization.
