RC2000A Dual Axis Antenna Controller

The Operational Mode Group consists of three modes: MANUAL, AUTO, and REMOTE. Programming
Mode Group consists of several modes: LIMITS, SETUP, RESET, AZIM SLOW, ELEV SLOW,
DELETE, RE-SYNC, POL LIMITS and CONFIG. Access to certain modes is controlled by the state of
certain CONFIG mode items and the Expert Access Flag. See section 2.4 for more information on
access to the various modes.

SAT:SBS 2
This mode allows the user to manually jog the antenna in azimuth and elevation using the AZ CCW, AZ
CW, DOWN, and UP keys and adjust the polarization using the POL CW and POL CCW keys. The
SPEED key is used to toggle the azimuth and elevation jog speed from fast to slow and vice versa. The
H and V keys will select the preset H and V polarizations for the satellite closest to the antenna's
present position. Polarization control is available in this mode only if the AutoPol feature is disabled.
When AutoPol is enabled, the polarization will be set according to the level present on the H/V input,
and 'RCV:' will be displayed before the polarization position field (instead of 'POL:').
In MANUAL mode the Scroll Up/Down keys can be hit to select the quantity displayed to the right of the
'S:' banner. The controller accepts two channels of AGC input, referred to as AGC1 and AGC2. Hitting
the Scroll Up or Scroll Down keys causes the S: banner to toggle between '1:' (AGC1 channel
displayed), '2:' (AGC2 channel displayed), and 'S:' (the greater of AGC1 or AGC2 displayed).
When the antenna is within 45 counts of an azimuth position AND 20 counts of an elevation position of
a satellite, which has been stored in non-volatile memory via SETUP mode, the satellite name will
appear in lower case letters. If the antenna is within 15 azimuth counts and 10 elevation counts of a
stored satellite position, the satellite name will be displayed in capital letters.
The polarization code is displayed to the right of the polarization position display field. When a polarotor
is present in the system, a lower case 'h' or 'v' will be displayed if the polarotor is positioned within 40
degrees of the horizontal or vertical positions, respectively, of the satellite located closest to the
antenna's present position. An upper case 'H' or 'V' will be displayed if a satellite name is displayed in
upper case letters and the polarotor is positioned within 10 degrees of the preset polarization positions
of that satellite.
If the RC2KPOL or RC2KHPP options are installed (which allow the RC2000A to interface to a
motorized feed with potentiometer feedback), and if the Pol Control? CONFIG mode item is set to One
Port, the lower case 'h' and 'v' display window is 160 polarization position counts and the upper case 'H'
and 'V' display window is 40 polarization position counts.
If the RC2KPOL or RC2KHPP options are installed (which allow the RC2000A to interface to a
motorized feed with potentiometer feedback), and if the Pol Control? CONFIG mode item is set to Dual
Port, then:
•
If the 'closest satellite' is specified to be either a C band or Ku band satellite (i.e. not a hybrid
satellite), the polarization code displayed will be either 'X' or 'x'. For this case both the
'horizontal' polarization field and the 'vertical' polarization field associated with the satellite's
entry in non-volatile memory will contain identical values. If the current polarization position is
very close to the polarization positions stored in non-volatile memory an 'X' will be displayed.
Somewhat close and an 'x' is displayed.
•
If the closest satellite is a hybrid satellite (both C and Ku band) and the two polarization
positions associated with the satellite's data entry in non-volatile memory are THE SAME, the
displayed polarization codes will again be 'X' or 'x'.
