Firmware

Configure Arduino firmware by K3NG

  1. Download stable or unstable arduino code, plus read documentation
  2. Download and change custom pins.h
    1. Enable External Analog reference
      1. in unstable code - uncoment line in rotator_features.h 
        #define OPTION_EXTERNAL_ANALOG_REFERENCE  //Activate external analog voltage reference (needed for RemoteQTH.com unit)
      2. in stable code activate this function with insert analogReference(EXTERNAL); to arduino code before analog_az = analogRead(rotator_analog_az); in master .ino file
            analogReference(EXTERNAL);
    analog_az = analogRead(rotator_analog_az);
  3. Edit rotator_features.h and enable: (delete // at the lines)
    1. LCD Display
      #define FEATURE_LCD_DISPLAY
    2. Azimuth voltage potentiometer
      #define FEATURE_AZ_POSITION_POTENTIOMETER
    3. Preset encoder 
      #define FEATURE_AZ_PRESET_ENCODER
#define OPTION_ENCODER_HALF_STEP_MODE
#define OPTION_ENCODER_ENABLE_PULLUPS
  4. Possible change the Baud rate to 9600 in (at K3NG source code its 115.k baud the preset)
    #define SERIAL_BAUD_RATE 9600

Power

The entire module can be powered from USB only, but there is a voltage drop, it is better to use an external +5V source, or a DC/DC converter and cut the power to the attached USB cable.

Pin 3 in CON1 (+5 volts input to supply measure the azimuth)- input stabilized voltage from power board This pin may be short connected (as picture below) with pin4 CON1 (+5 volts to interface), then the voltage measurement uses a common 5V voltage from the power supply module.

Connect DC Rotator (DB15 female) and power inputs

  • Need three jumper
    • short DC position P6 jumper switch
    • short JP1 jumper
    • short PHASE-SW (center) position CON1

Connect AC Rotator (DB15 female) and power inputs
