RC2000A Dual Axis Antenna Controller Chapter 3 Installation/Setup 31
Here is the procedure for installing and configuring the AutoPol feature:
1. Identify an output on the receiver, which can be used to drive the AutoPol input on the RC2000A.
Note if a high level output corresponds to V polarization or H polarization.
2. Connect the AutoPol input as shown in figures 3.2 or 3.3.
3. Go to CONFIG mode, use the SCROLL UP and SCROLL DOWN keys to bring up the 'AutoPol
Enable' prompt, and key in 1 followed by the ENTER key to enable the AutoPol function.
4. While in CONFIG mode, use the SCROLL UP and SCROLL DOWN keys to bring up the 'AutoPol
Vpol Level' item. If a high level corresponds to vertical polarization, key in 1 followed by the ENTER
key. If a high level corresponds to horizontal polarization, key in 0 followed by the ENTER key.
5. Go to MANUAL mode and verify that the AutoPol feature works properly. In MANUAL mode, when
the AutoPol feature is active the polarization display banner reads 'RCV:' rather than 'POL:'.
3.9 Simultaneous Azimuth and Elevation Movement
The RC2000A has the capability to move the azimuth and elevation axis actuators simultaneously
during AUTO mode moves. The use of this feature is subject to a limitation in that the total current draw
for both 36 volt actuators combined cannot exceed 8 amps. If this requirement is satisfied over all
operating conditions, simultaneous azimuth and elevation movement can be enabled by going to the
CONFIG mode 'Simultaneous Az/El Enable' item and keying in 1 followed by the ENTER key.
3.10 Installation and Setup Checklist
This section gives a summary of the installation and configuration procedure outlined in this chapter.
The summary is presented in the form of a checklist.
1. Before power is applied verify that the line voltage is correct. Check the displayed voltage in the
fuse holder window.
2. Make sure that the memory has been cleared. The controller should come up in LIMITS mode.
3. Make the required electrical connections. A shielded cable must be used for the position sensors
and the shield must be connected at the back of the controller and not at the antenna. Refer to
figures 3.1, 3.2, and 3.3.
4. If the RC2KPOL or the RC2KHPP option is installed (which allows the RC2000A to interface to a
motorized feed with potentiometer feedback), make the required electrical connections for the motor
and sensor, verify the polarity of the motor and the position feedback sensor, and set the
polarization limits. Make sure that when the CCW key is depressed to jog the polarization motor
counter-clockwise, the displayed position count INCREASES. Use caution to avoid damaging the
potentiometer.
5. Go to LIMITS mode and verify the motor drive polarity. Set the azimuth ccw, azimuth cw, down, and
up limits. If a modified polar antenna mount is used, get the mount to track the Clarke Belt and set
the GEO ELEV POSITION.
6. Use the AZIM SLOW and ELEV SLOW modes to set the azimuth and elevation slow speed codes.
7. Go to SETUP mode and program in the satellites. If an az/el mount is used, review section 3.6
which describes a procedure for locating satellites that makes use of the RC2000A's ability to
display azimuth and elevation position in an angle format.
8. If desired, enable the AutoPol feature to slave the controller's polarization control output to a
satellite receiver. A digital output on the receiver must be connected to the AutoPol input of the
controller and the AutoPol feature must be enabled via CONFIG mode.
