Some Additional 4o3a Rotator Genius (RG) Notes

The 4o3a Rotator Genius (RG) I’m setting up has a few idiosyncrasies worth mentioning:

  • Initial setup required a male-to-male USB cable or manipulating the buttons on the bottom of the unit to enter the menu system and a static IP address.
  • (This applies when contrasted to AG v 1.0, as AG v 2.0 uses a different connector) The Eurostyle Terminal Block for DC power is opposite polarity of the same plug when used in a 4o3a Antenna Genius.  You can also power the RG with up to 48VDC.  Output to the Rotator control cable is adjustable in coarse increments to lesser amounts.  (Remember to calculate and then check your voltage at the rotator end of the cable. – you’re going to want 7v or higher at the sensor end.)
  • The azimuth sensor to controller cable uses an Ethernet plug at the controller but you will have to open the sensor and wire it at the tower end.  I’ve made a suggestion to the 4o3a group to change the sensor end to an internal Ethernet setup, to minimize the fussy stuff being done on the tower.
  • Some the sensor to controller specifications in the manual appear daunting but are really the standards you would expect.  Just the naming is professional rather than consumer level.
  • It is possible to reverse the sensor cover which would reverse the “this way north” markings 180 degrees.  4o3a will be added something to their manuals to remind people to match the external and the internal north markings.  The internal north marking is printed on the sensor’s PC board.

    Hello Steve, I am considering the Rotator Genius for an older Yeasu 1000SDX. I currently have a 14 year old RT21 from GreenHeron but the rest of my station now is Flex 6700, PGXL, TGXL, and Antenna Genius. Are you still using the RG and what are your current thoughts about the RG?

      Hi Steve N3MX

      I do not have the Rotator Genius in operation yet.

      Three setbacks:

      My CAT-5 from shack to tower is giving me trouble.
      I forgot to physically install it during the larger-than-expected T-12 assembly & erection, while the lift was on site.
      The rotator jackshaft to actual mast drive chain came off in the cold of winter, and has to be fixed.

      On the upside the lift is now available, so I hope to get the 4o3a RG (Rotator Genius) in operation this fall.

      Expecting to post on how it goes of course.
