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 that 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 AUTO
USE SCROLL UP/DOWN, ENTER TO SELECT
Satellites that 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 35
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. Press the ENTER key to select the desired satellite.
3. After the satellite has been selected, the controller will prompt the user to specify the desired
polarization if a 1-Port feed was selected for the Pol Equipment code CONFIG mode item. The controller
will then proceed to move the antenna into postion.
4. Antenna movement can be stopped at any time by pressing the STOP key. Simultaneous azimuth
and elevation movement can be enabled via the Simultaneous Az/El CONFIG mode item. If
simultaneous az/el 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
5.8.6 - Azimuth and Elevation Drive Options.
5. When the automatic move is completed, control will transfer to MANUAL mode if the target is a
geostationary satellite. If the target of the automatic move is an inclined orbit satellite, TRACK mode
receives control. Only the RC2500B is capable of tracking inclined orbit satellites.
5.3 REMOTE Mode

SBS 2
In REMOTE mode the controller only responds to commands received via the built-in RS-422 serial port.
REMOTE mode can only become active if the Remote Mode Enable CONFIG mode item is enabled. If
REMOTE mode is enabled, it can become active by pressing the MODE key twice from MANUAL Mode,
or in response to the reception of a valid command via the serial port. Note that TRACK mode can
process certain serial port commands. The REMOTE mode screen is similar to the MANUAL mode
screen. The only differences are that the satellite longitude and 'SPEED:' banners are not displayed.
Only the MODE key is active when REMOTE mode is active.
5.4 TRACK Mode
TRACK Mode is only available on the RC2500B model. The RC2500A does not operate a track mode.
A:178.40 E: 44.27 P: 34.3 V S:621 TRAK K
GSTAR 3 PROGRAM IDLE 15.56.0-MENU
TRACK mode is invoked either from SETUP mode or AUTO mode to track inclined orbit satellites.
TRACK Mode consists of 4 sub-modes: STEP, PROGRAM, SEARCH, and ERROR. The track sub-
mode which is currently active is displayed to the right of the satellite name. Status information relating to
the submode which is currently active is displayed to the right of the sub-mode. The tracking algorithms
along with these sub-modes are described in section 4.2. The frequency band (L, C, or K) of the
transponder which the controller assumes that it is tracking is displayed in the upper right hand corner of
the display.
