The antenna will be shipped with four flexible conduit runs (with wire pulled through the conduit) to the
elevation motor, elevation sensor, azimuth sensor, and azimuth motor attached to the interface box. The
installer will have to attach these conduit runs to the elevation motor, elevation sensor, azimuth sensor, and
azimuth motor. The two other conduit runs (elevation sensor to elevation limit switch conduit run and the
azimuth sensor to the azimuth limit switch conduit run) will be included with the interface box but not
attached to anything - the installer will have to place these. The Teflon tape included with the installation
kit can be used on any conduit fitting which cannot accept a sealing gasket or O ring (such as the 1/2" to
3/4" bushing used on the limit switches).
Once the conduit has been attached the wiring connections can be made.
The installer must make the following connections (please refer to figures P1 and P2).
1. The RC2000 to Interface Box Interconnect cable must be installed. Make the connections at the
RC2000. Refer to Chapter 3 in the RC2000 manual for more information on the connection at the
RC2000.
2. The motor control signals on the RC2000 to Interface Box interconnect cable must be attached to the
AZ1_CTL, AZ2_CTL, EL1_CTL, and EL2_CTL terminals on the circuit board in the interface box.
3. The sensor cables in the RC2000 to Interface Box interconnect cable will have to be spliced to the
Belden 8772 cable in the interface box. Please reread section 3 of this manual and refer to figure 7 in
the RC2K90INT-1 interface box manual before making the splice. Use the 3M Scotchlok connectors
to make the splice. Proper connection of the sensors is critical to the operation of the antenna
controller.
4. Connect the sensor cables to the sensors (refer to figure P1). At the sensors, cut off the drain wire and
place a piece of heat shrink tubing over the sensor cable where the insulation is cut so that the shield
