RC2000C Polar Tracking Antenna Controller
Chapter 5
The Operational Mode Group consists of four modes: MANUAL, AUTO, REMOTE, and TRACK.
Programming Mode Group consists of several modes: LIMITS, SETUP, RESET, DELETE, RE-SYNC,
and CONFIG.
5.1

MANUAL Mode

AZ:178.4 EL: 44.2 PL:
SBS 2
This mode allows the user to manually jog the antenna in azimuth, elevation, and polarization using left,
right, up, and down arrow keys and the CW/CCW keys. The H and V keys will select the preset
horizontal and vertical polarizations of the satellite which was last a target of the auto-move system. Note
that polarization control is available only when the AutoPol feature is disabled. When AutoPol is enabled,
the 'PL:' banner in the MANUAL mode display will change to 'AP:'. The AutoPol system is described in
section 3.8.
The 'S:' field displays the stronger of the two receiver AGC voltages available to the controller via the
AGC1 and AGC2 terminals on the J1 connector on the back of the controller. The AGC Adjustment
procedure is described in section 4.4.1 - AGC Adjustment and Configuration.
When the antenna is in the vicinity of a satellite which was the target of the last Auto Move operation, that
satellite name and longitude will be displayed. When the current polarization setting is in the vicinity of
the preset horizontal or vertical polarizations of the satellite which was the target of the last Auto Move
operation, either 'H', 'h', 'V', or 'v' will be displayed. The capital letters will be displayed if the satellite
name is displayed, and the lower case letters if the satellite name is not displayed. If there is no
polarization indication, it means that the antenna's current polarization setting is somewhere in between
the preset polarization values.
5.2

AUTO Mode

SELECT A SATELLITE: PANAMSAT-1
USE SCROLL UP/DOWN, ENTER TO SELECT
Satellites which have been stored in the controller's non-volatile memory (via SETUP mode) can be
recalled via AUTO mode. Azimuth, elevation, and horizontal and vertical polarization presets for up to 25
satellites may be stored in non-volatile memory. Here is the procedure for recalling a satellite:
1. Toggle the MODE key to enter AUTO mode.
2. Use the SCROLL UP and/or SCROLL DOWN keys to scroll through all of the satellites stored in non-
volatile memory. Hit the ENTER key to select the desired satellite.
3. The controller will next prompt for H or V polarization. After the satellite has been selected, the
controller will prompt the user to specify the desired polarization if the AutoPol feature is not enabled.
If AutoPol is enabled, the polarization will be controlled according to the digital level present on the
H/V INPUT connector on the back of the controller. Once the pol is selected, the controller will move
the azimuth axis first, then the elevation, then fine-tune these positions.
4. Antenna movement can be stopped at any time by pressing the STOP key. Simultaneous azimuth
and elevation movement can be enabled via the CONFIG mode item. If simultaneous movement is
not allowed, the controller will first position the antenna in azimuth and then elevation. The antenna
movement will be controlled by the CONFIG mode items outlined in section 5.10.7 - Azimuth and
Elevation Drive Options.
