CONTROL-1500A Single Axis Antenna Controller
MANUAL
POS
GALAXY 6
In manual mode you can:
1. Jog the antenna about the fundamental control axis using the ARROW KEYS
2. Toggle the speed from fast to slow (and vice versa) with the SPEED key.
3. Jog the polarization with the CCW/CW keys.
4. Use the H/V keys to toggle between the preset H and V polarizations of the satellite which
was the last target of an AUTO move.
When MANUAL mode is active the following information is displayed on the top row of the
LCD: antenna position, polarization position, polarization position code (H or V) and the
current signal strength. The signal strength is derived from a receiver or modem automatic
gain control (AGC) output or a dedicated beacon receiver.
The bottom row of the LCD displays the satellite name and the antenna speed ('F' for fast, 'S'
for slow). While jogging the antenna at slow speed a symbol is displayed to the right of the 'S'
banner. The symbols displayed are ... \, |, /, -, \, ., and + and a function of the voltage applied
to the drive.
The CONTROL-1500 employs a software servo system to maintain a constant rate of slow speed
movement. The user specifies a slow speed via the Slow Speed CONFIG mode item. As the
antenna moves at slow speed the controller determines the antenna speed by measuring the
time interval between successive position pulses. The voltage applied to the drive is adjusted
to maintain a constant antenna speed. As the voltage applied to the drive increases the \, |, /,
and – symbols appear to rotate clockwise. Similarly, as the voltage ramps down the symbols
appear to rotate counter-clockwise. The . symbol is displayed when the minimum voltage is
applied to the drive and the + symbol is displayed when the maximum voltage is applied to the
drive.

This mode allows the user to automatically position the antenna on any satellite that has been
programmed into memory via SETUP mode. The list of programmed satellites is reviewed via
the SCROLL UP/DOWN keys, and the ENTER key initiates the automatic move. The STOP
key will terminate the move. After the automatic move, MANAUL mode will become active.
