There is nothing special about interfacing the RC-210 controller to a Mastr II.
It has audio inputs and outputs, COR, CTCSS Decode and PTT lines just
like any other controller.
Get a piece of paper and draw out the radio connector, and look at
the pinout and the signal voltages.
Some tips:
1) You are going to want to do the Chuck Kelsey WB2EDV mod to the 10v card.
2) You are going to want to read the John Holden N7IQV article on
the power supply.
3) you are going to want to join the Mastr II email list
<http://www.repeater-builder.com/rbtip/mastr.html>
4) If you don't have it already you are going to want to start a
system documentation binder, starting with a full set of LBIs for
your station. Start with the Product Code 67 file and work your way
down the lists.
Search the web for "Mastr II" and "repeater" and read all the various
interfacing articles. It won't matter if it's an ACC, a Link Comm
(RLC series), NHRC or Scom brand controller - you will see that in
every single case they end up with a full duplex base station cabled
to a repeater controller.
It's getting that full duplex station operational that's half the
battle, and the adaptation of signals from and to the station and the
repeater controller that's the other half.
You will end up with a custom cable between the controller and the
station chassis, with maybe a signal buffer or two (in case a signal
is high impedance and can't be loaded down), or maybe a voltage level
converter or a signal inverter somewhere.
There is some GE station interfacing information on the
<www.repeater-builder.com web> site (yet). Want to write another
article from a newbie point of view? It might help the next guy...
The place I'd start is the three articles in the Mastr II station
section - the first is titled "Mastr II Station to Repeater
Conversion" by Don Woodward KD4APP , the second is "Interfacing the
Mastr II Station to an ACC 850 Repeater Controller " from ACC, the
third is "SCOM 7K Controller Connections to Mastr II" from Scom.
I'd read all three, combine them into a master plan (with the Chuck
Kelsey WB2EDV mod to the 10v card first), then proceed from
there. Take lots of photos as you go, write it up into a mod
article, and send it to repeater-builder.
One guy sent me an email a few years ago and said that he learned
enough from my Motorola Mitrek mobile Interfacing article
<http://www.repeater-builder.com/mitrek/mitrek-interfacing.html> to
find the right places in his Mastr II station, but that's taking my
enamples, reversing them to theory, and then applying that
theory. And besides, the Mitrek pair I set up was an intermittent
duty point-to-point link, not a continuous duty repeater.

Does anyone on this list have pictures or scematic of a VHF Master
II hooked up to an ARCOM RC-210?
We are starting to work on one for our Club Repeater and I am
looking for some examples for reference.
