Stan,
Very interesting and I see you can actually use them without connecting them to
a PC, so this is good alternative too.
I will Email you off list with some questions.

Subject: Re: [TowerTalk] M2 RC2800PX modification to control a Prop Pitch Rotor?
I have a Green Heron controlling the prop pitch on my 40m Yagi and have had it
for about 7 years. It is a very nice control box. I had several other prop
pitch rotators that I wanted to also control but did not want to spend so much
money to have four of the Green Heron Controllers.
I bought three EA4TX ARS-USB units. You have to supply the voltage for
whatever rotator you are using. The units will connect to the computer via USB
and include a program or you can use one of several contest logging programs.
After buying three of these units (two that I connected to prop pitches and one
for a Tailtwister) we made a deal with EA4TX to distribute his product in the
US and Canada. There are two models - one for Azimuth and one for Azimuth and
Elevation for those who want to do EME or Satellite.
I have since moved all the rotators control boxes to one side of the room and
they are connected to a computer that is networked with all the other
computers. It is really nice to be able to turn any antenna from any computer
by typing in a heading or call sign prefix. The EA4TX box will work with any
rotator that uses voltage feedback from a potentiometer. The Green Heron will
work with either a potentiometer or pulses from a reed switch with a magnet
mounted to the motor shaft.
My honest evaluation is that if I were going to only have one control box and
was not going to connect it to a computer, I would prefer the Green Heron
because of the knob on the front. However, If I were connecting it to a
computer and the position was to be determined via a potentiometer in the
rotator, I would prefer the EA4TX box because of price.

Do not buy the M2 controllers. They are devices that only the designer
could love. They are not user friendly. Better to get a Green Heron. They
work great!
