Introduction and overview

A diagram of a typical Rotator Genius setup with a single sensor, controlling a single rotator:

1. Rotator Genius is wired to the rotor motor. It is mounted on the base of the tower in waterproof housing.
   Alternatively, it could be hung on a wall in the shack.

2. Rotator Genius Sensor is an electromagnetic compass. It features waterproof housing and is mounted on a boom. It is connected to the Rotator Genius by a standard Cat5 Ethernet cable.

3. You can use a typical Small Office Home Router found in homes worldwide to connect Rotator Genius to your local network. A “dumb” switch will also work. RG uses IPv4 and is compatible with most switches and routers on the market.

4. You can control and interact with RG using a wireless Android or Windows device.

5. Most users will use the same shack Windows PC running various other control and logging software.
   You can control your RG remotely over the internet as well. Setting this up requires some understanding of your networking equipment and technology. You must use a VPN connection since there is no security implemented on the device.

Power Supply

RG will work with any power supply between 13.8V and 48V DC. Choose a power supply with at least the same voltage as the rotor you intend to control.

You can choose a bigger power supply as well. RG can supply 100%, 75%, 50% or 25% of your power supply voltage to the rotor motors. This will be covered in more detail in this in the 3. Connecting Rotators and 3.8 Rotator Connection Examples sections.

Screw-in your power supply wires to the terminal block green terminal block.
Connect the terminal block to the DC IN connector. + and – are marked on the pictures below.

As soon as you power the device the LED display will show azimuth values for the connected sensors. If the sensors are not connected, azimuth values will be shown as N/A (not available).

Buttons and Controls

The bottom of the device features three buttons. The buttons have dual functions. They are used for either manual control of your rotors or configuration.

1. Select Rotator Pressing and releasing this button instantly (releasing under one second) toggles rotor selection. If R1 is selected it will select R2 and vice versa. On the front LCD display you will see the ➡ symbol next to the selected rotor (# was used in earlier versions). On the picture below R1 is currently selected.
   

2. CW Pressing and holding this button rotates the currently selected rotor in a clockwise direction. The green CW led on the front of the device will light up, and the arrow on the display next to the selected rotor will start moving.

3. CCW Pressing and holding this button rotates the currently selected rotor in a counter-clockwise direction. The green CW led on the front of the device will light up, and the arrow on the display next to the selected rotor will start moving.

4.  MENU Press and hold this button for two seconds to enter the settings menu. RG app will be offline and you won’t be able to control your rotors while using this menu. Details about these settings are covered in the next chapter.

Connecting and Wiring The Rotors

Rotator Genius can control five different categories of rotors:

1. Low Range DC motors – 3 to 48V, up to 15A of current.
2. Low Range AC motors – 3 to 48V, up to 15A of current.
3. High Range AC motors single phase – 110 to 220V.
4. High Range AC three-phase motors – 110 to 380V.
5. Prop Pitch motors.

DIP Switches on the back of RG are used to configure the type of rotor you intend to control.
First RG series have wrong stickers if this is the case know that the DIP switches are always next to the Sensor connectors as on the picture below.
The remaining 8 DIP switches next to the ethernet connector serve no purpose in the current version and are reserved for future use.

The table below briefly sums up each DIP switch function.
Details are covered in separate chapters.

| OFF| ON
---|---|---
DIP1: Low Range or High Range?
DIP2: Reverse CW and CCW
DIP3: Prop Pitch
DIP4: Using Breaks?
DIP5: Using Soft Start?
DIP6: AC or DC motor?
DIP7 and DIP8: Percentage of the power supply voltage supplied to the rotor motor?| Low Range Motor

50% of power supply voltage to the rotor motor
75% of power supply voltage to the rotor motor
100% of power supply voltage to the rotor motor

 DIP1: Low Range or High Range

High Range should be selected if your motor is single or three phase between 110 and 380V AC.
Set DIP1 to ON to configure your rotor as High Range.

A low range should be selected if your motor is 3V to 48V AC or DC. The maximum current is 15A.
Set DIP1 to OFF to configure your rotor as Low Range.

Note that even though you can control 3V motors the minimum power required for Rotator Genius to work properly is at least 12V (13.8V recommended).

DIP2: CW and CCW Reversed

Set DIP2 to ON to reverse the CW and CCW direction.
This can be used to avoid rewiring if you connected your rotor the wrong way.

DIP3: Prop Pitch

Set DIP3 to ON if you are using a Prop Pitch motor.

DIP4: Rotor Brakes

Breaks are commonly found on Low Range motors.
Voltage on the breaks must be the same as the voltage on the rotor motor.

Set DIP4 to ON to enable using breaks.
Set DIP5 to OFF to disable soft start (these features are not comparable).
Rewire your rotor to match the diagram below.
The common wire of AC motor is connected to the center pin.
Motor ends are connected over the brake relays as shown on the diagram below.

When you execute the CW or CCW command the brake solenoid will be powered first about half a second before the motor. When you release the command, the motor will stop being powered and the break will be powered for half a second more. This enables the release of activation of the brake, by properly sequencing it.

DIP5: Soft Start

Soft Start uses PWM to gradually start and stop your rotor instead of using full power for the entire time.
Soft Start is supported on Low Range AC and DC motors.
Soft Start can not be used if the break feature is used.
Set DIP5 to ON to enable Soft Start.

DIP6: AC or DC

Configure Low Range motor as AC or DC.
Set DIP6 as ON to configure the rotor as AC.
Set DIP6 as OFF to configure the rotor as DC.

 DIP7 and DIP8: Voltage Configuration

You can use DIP7 and DIP8 switches to configure supplying 25%, 50%, 75% or 100% of your power supply voltage to your rotor. This only applies to Low Range motors.
Take a look at the table with examples of 12V, 24V, 36V and 48V:

If the 25% increments are not accurate enough, you can use a small potentiometer inside the device on the PCB for fine-tuning.

Rotor Connection Examples

The examples below are designed to provide you with a clear idea of how to connect your rotor to the RG.
Models may vary over time, so make sure you double-check your rotor’s documentation before connecting.

Low Range DC Rotors

AlfaSpid (Spid in Europe) motors are mostly 12V DC electric motors. This includes BIG-RAK, BIG-RAS, RAEL, RAK, RAS, RAU, SPID RING – 01 and SPID RING – 02 models.

Using a 24V PSU, the DIP Switch configuration and wiring look like this:

| OFF| ON
---|---|---
DIP1: Low Range or High Range?
DIP2: Reverse CW and CCW
DIP3: No Function
DIP4: Using Breaks?
DIP5: Using Soft Start?
DIP6: AC or DC motor?| Low Range Motor
CW and CCW normal
none

ON| 25% of power supply voltage to the rotator motor
50% of power supply voltage to the rotator motor
75% of power supply voltage to the rotator motor
100% of power supply voltage to the rotator motor

A 16V PSU would have the same wiring and settings except the DIP7 and DIP8 would be set to 75% voltage:

DIP7| DIP8|
---|---|---
OFF
OFF
ON
ON| OFF
ON
OFF
ON| 25% of power supply voltage to the rotator motor
50% of power supply voltage to the rotator motor
75% of power supply voltage to the rotator motor
100% of power supply voltage to the rotator motor

Lastly a 12V PSU configuration would look like. DIP7 and DIP8 set power with 100% voltage:

In order to verify you connected the rotors correctly, use the CW and CCW buttons on the device to control your rotor manually. Use Select to switch between the selected rotators.

Low Range AC Rotors

Low range AC motors are AC motors that use between 3V and 48V.
RG can convert the supplied DC power to AC for powering rotor motors.
Make sure to set DIP6 to ON to supply AC voltage.
Common wire is connected to PIN3 (pins are counted from left to right).
CW and CCW lines are connected to PIN1 and PIN2.
If you swap CW and CCW lines you can use DIP2 to reverse them in software rather than rewire them.
DIP7 and DIP8 are configured to 100% voltage in this example. This will vary depending on your setup.

Single Phase High Range AC Motors

Set DIP switch 1 for your corresponding rotor (A or B) to ON. This configures the rotor to a high range.
Supply the AC power for driving the rotor onto the dedicated 3-phase port. This power will be outputted over the High Range port. Connect your rotor on to the High Range output port as shown on the diagram below.

At least 13.8VDC (up to 48VDC) of additional is needed to power the RG logic and sensors regardless of the AC power.
Important: Make sure to connect the N (neutral) wire properly to avoid damaging your rotor.

Three Phase High Range AC Motors

Set DIP switch 1 for your corresponding rotor (A or B) to ON. This configures the rotor to high range.
Supply the AC power for driving the rotor on to the dedicated 3 Phase port. This power will be outputted over the High Range port. Connect your rotor on to the High Range output port as shown on the diagram below.

Motor shown on the diagram is in a triangle configuration as an example. RG supports both triangle and star configurations.
At least 13.8VDC (up to 48VDC) of additional is needed to power the RG logic and sensors regardless of the AC power.

Prop Pitch Motors

Common wire is connected to PIN2 (pins are counted from left to right).
CW and CCW lines are connected to PIN1 and PIN3.
Make sure to set DIP3 to ON, this specifies the special case Prop Pitch motor.
Set DIP1 to ON to configure the motor as DC.
DIP7 and DIP8 are configured to 100% voltage in this example. This will vary depending on your setup.

Exceptions

 T2X

The T2X rotator has issues with PWM scaling.

The only working setup is a 28-30VDC power supply and 100% PWM rate.
The connection diagram is shown on the left and you can find the physical connection layout on the images below.

Testing and Verifying

Use the CW and CCW buttons to move your rotor manually to ensure proper connections/configuration has been made.
Use the Select Rotator button to switch between the rotors.
An arrow on the most left on the LCD screen is the indication of the selected motor.

The Electromagnetic Sensor

Sensors read the magnetic azimuth and send the position to the RG. Sensors are carefully calibrated in the factory and you can use them out of the box.

The arrow on the sticker shows the direction it is pointing.
This sensor must be as parallel to the ground as you can get it- not tilted at all.
Place the Sensor at least 80cm away from any metal materials and ferromagnetics.
You can mount it to the aluminum antenna boom.
The sensor is placed in a plastic waterproof housing.
It is very light so you can use plastic cable strips for mounting.
In order to connect the sensor open it by unwinding the four screws on the box.
Data is sent over UTP network cable using the RS485 protocol.
Two wires are used for VDC, two wires for GND and single wires in A and B for data.

Sensor wiring:

1. ORANGE/WHITE
2. ORANGE
3. BLUE and BLUE/WHITE
4. BROWN and BROWN/WHITE| to

---|---|---

Green is unused. We recommend to cut it off completely on this end.

For the device side RJ45 wiring the T-568B standard is used:

1. ORANGE/WHITE
2. ORANGE
3. GREEN/WHITE
4. BLUE
5. BLUE/WHITE
6. GREEN
7. BROWN/WHITE
8. BROWN

Once connected, the azimuth value will be displayed on the Rotator Genius LCD screen. Move it around and verify it works before installing it on your antenna. It should be parallel to the floor and moved only on X and Y axis so place it on some flat surface like a table.

Again make sure there are no metal materials and/or ferromagnetics around while testing.

On the front display, you can see the azimuth value of connected sensors as well as the set output voltage to the motor.
Green LEDs will indicate if a rotator is out of configured limits and if it’s being rotated in CW or CCW direction.
The red LED is a warning indicating your rotor is outside defined software limits. More on this in the software section.

Sensor Correction

In case of sensor inaccuracies caused by disturbances in the EM field we can recalculate the azimuth using our correction algorithm.
You can choose to do correction using four or eight points.
Four-point algorithm has a maximum deviation of +/- 45 degrees.
Eight point algorithm has a maximum deviation of +/- 22 degrees.
You will need to experiment and see which option works best in your case.
Before proceeding you will need:

1. Paper and pen to write the measured values down.
2. A regular compass for real-world reference points.

The sensor should be attached to the boom in the same way it is going to be used.
Do not open the sensor correction window before doing the measurements because it will prevent you from using the RG app.
You will need your app to move your antenna.

Four Point Sensor Correction Procedure:

1. Rotate the antenna to actual North. Write down the value the sensor reads in this position.
2.  Rotate the antenna to actual East. Write down the value the sensor reads in this position.
3. Rotate the antenna to the actual South. Write down the value the sensor reads in this position.
4. Rotate the antenna to the actual West. Write down the value the sensor reads in this position.
5. Open the Sensor Correction menu.
6.  Tick the Active box.
7. Select Four points.
8. Enter the values to the corresponding boxes.
9. Press Save.
   Rotator Genius will now take into account the real-world values and recalculate the azimuth accordingly.
   You can uncheck the Active box at any point to revert to raw sensor data.
   Eight Point Sensor Correction procedure works exactly the same with additional values for NE, SE, SW, NW.

Recalibrating the sensor

Sensors are carefully calibrated in the factory. If the sensor is showing bad azimuth values try using the sensor correction algorithm first. (chapter 4.1)

The only time you would need to do this is if we don’t calibrate a sensor at all by mistake.

A symptom for this is a sensor that shows a fixed value constantly no matter where you point it at.

So please do not attempt to do this unless you are absolutely sure it is necessary — all factory calibration data will be lost permanently.

Calibration requirements:

The sensor should be attached to the boom in the same way it is going to be used.

1. Your boom must be able to make full 360-degree turns.
2. The more full rotations you can make the higher the precision will Around five rotations is considered is optimal.
3. You can rotate in any direction, CW, CCW or mixed. The main point is letting the sensor sense all 360 points.
4. The slower you rotate while calibrating the higher the precision will be in the end.

Calibration process:

1. In order to start the calibration process, you need to disconnect the sensor from the device and open the casing.
2. Set PIN 1 and PIN 6 to ON, as shown in the picture. Do NOT use a metal screwdriver for this because it will mess up the readings.
3. Connect the sensor back to Rotator Genius.
4. There will be no reading on the LCD display or Panel Application during the calibration mode.
5. Making five full rotations in any direction, back and forth, one way, doesn’t matter.
6. When done, set PIN 1 and PIN 6 to
7. The sensor should now be calibrated. You will see a reading on your LCD display and Panel Application.
8. Repeat the process if not satisfied with the results.
9. When done seal the sensor box.
