• AS-RA-S1 - Digital Rotator Controller

New! Special introduction price: $425.00. Please specify your rotator make and model if you want to and we can set the pigtail connector wiring, internal jumpers and partially configure the controller for you.

The RA-S1 is a digital controller for azimuthal rotators. Its main features are: 

  • Voltage output regulated with PWM (Pulse Width Modulation)
  • Soft-start and Soft-stop With the PWM speed control, the controller softly ramps up and ramps down the rotator’s speed on every operation mode.
  • On-hand speed controls The potentiometer’s SPEED to make it easy to adjust the rotation speed.
  • Point and Shoot Choose an azimuth with the POS potentiometer, press GO and let the controller softly guide the rotator to the chosen bearing.
  • Offset definition Quickly corrects the azimuth your antenna is pointing at, without the need of a new calibration.
  • Software defined limits With them your stacked antennas won’t hit the tower. It is very intuitive to configure.
  • Serial RS-232 communications with DB-9 or USB The RA-S1 controller uses the Yaesu protocol GS232A, making it easy to use with every existing program.
  • Firmware Upgradeable It is possible to upgrade the firmware of the controller easily with the USB port. Your controller will never be out of date.
  • Full compatibility with most rotators The RA-S1 was developed to work with most of the available rotators in the market, being able to control AC rotators (24 or 36 V AC) and DC (12, 24 or 36 V DC)*, that have positioning feedback by pulses or internal potentiometer. The rotators commonly used (Yaesu G-800, G-1000, G-2800, HyGain HAM-IV, T-2, Pro.Sis.Tel PST-71D, PST-61D, PST-2051, PST-641, M2 Orion 2800) can be used with these systems.
  • Unit dimensions are 8" x 8" x 4" H
