Web control four rotator, fifteen relays and many other features that come from Raspberry PI RemoteQTH server.

Main functions:

• Control the four rotators using the light buttons,
  rotary encoder and with a two-line display for each rotor.
• Same control remoted via web interface or telnet
  – only click to map and confirm rotating.
• Rotator module can directly control the motor of the rotator
  • DC version of the phase-change
  • AC version switching CW or CCW winding

  Or you use the relay contacts to control your control box.

• 24 freely configurable relay (15 in model B) (first used for server power on/off)
  as single pole, single throw or single pole, more throw
  – suitable for switching antennas.
• GPIO interface power board associating functions
  • Relay switching from GPIO
  • DC/DC converters power supply 5V for Raspberry PI
  • DC/DC converters power supply 5V for four arduino rotators module.
    Turns ON the first GPIO output.
  • Available four DC/DC converters – custom voltage power supply for each motor of rotator. In the range of 2 to 37V an max current 3A.
  • Include A/D converter for four voltage measurement
  • Expand I2C bus – available connect next temperature or voltage sensors
• All in simple 2U Rack case.
  • Case made to measure from 2 mm aluminium.
  • Laser engraving plastic front panel.
• Each the rotator unit interface, based on arduino (code by K3NG) contains:
  • LCD.
  • Lighting button (CW, CCW, Start).
  • Preset encoder.
  • Three relay (CW, CCW and Brake).
  • Arduino nano module.
  • Ready for AC and DC rotators.
  • Analog input.
  • 5V power voltage.
• Server requires a DC power supply ranging from 9 to 40 volts.
  Voltage is dependent to the rotator, if we are powered motor directly from the server.
• If you have a rotator AC motor, the server has terminals
  for connecting the AC voltage for each rotor separately.
• Another server utilization

•  Export USB/serial interface to IP.
  • CW keying from web interface.
  • Connection RaspiCam Webcam.
  • Access without public IP adress (n2n vpn).
  • Switching relay by TRX frequency using Band decoder function.
• Necessary components
  • Rack case.
  • Rapsberry PI + 4GB SD card with RemoteQTH server.
  • GPIO interface power board.
  • Relay board.
  • Four arduino rotator interface.
  • Usb hub with external power supply.
  • DC power supply 9-40V dependency to max DC rotator voltage.
  • AC power supply if AC rotator instaled.
