Antenna Rotator System - RCI Boards

 RCI Second Edition "RCI-SE":

A new RCI Board has being designed. This board (12cm x 12cm, 4.76” x 4.76”) is available for Azimuth or Azimuth and Elevation operation with all the components on the same PCB. It's connected to the computer via a LPT Port. 

• There are 5 relays available (Azimuth and Elevation model):
  • Left
  • Right
  • AUX, usefull for those rotors that include  a Brake or Speed control.
  • Up
  • Down
• 2 x 8 bits ADC. (10 bits ADC resolution available as an option)
• 1 interface for a computer LPT Port
• 2 x Multi-turn trimmers for Azimuth adjustment (CCW & CW)
• 2 x Multi-turn trimmers for Elevation adjustment (Up & Down)
• Input from the rotor Pot. Feedback supports Differential mode and Ground reference.

RCI board: (Obsolete)

The classic RCI Board, is a small PCB (12.5cm x 8cm, 4.96” x 3.17”) that connects between the Rotor Control Unit and a LPT port on your computer.

• This board is a basic option that allows for computer control of an Azimuth rotor. There are 3 relays available:
  • Left turn
  • Right turn
  • AUX, usefull for those rotors that include  a Brake or Speed control.
• 2 x 8 bits ADC. (10 bits ADC resolution available as an option)
• 1 interface for a computer LPT Port.

Daughter Board or RCI-EL: (Obsolete)

• This second board is necessary for those who want to use an elevator. It connects to the RCI board and it has 2 relays. The combination of RCI + RCI-EL will let you control a rotor (Azimuth) and an elevator (Elevation).

RCI + RCI-EL PCB

Specifications both models:

• Each relay has 2 circuits (5A/220VAC–50Hz, 10A/110VAC–60Hz).
• Input voltage: between 12-14 VDC.
• Current: stand-by mode less than 10mA, when relays are energized current is less than 160mA.
• 2 A/D converters (8 or 10 bits)
• DB-25F connector for attaching to a LPT (parallel) port on a PC.
