Mark,
The i20R is marketed as an on-site repeater controller for various Motorola
and Kenwood commercial radios. It is capable of transparently passing
either TPL or DPL, or it can strip and replace TPL or DPL with the same or
different codes, and it will handle up to ten users. The i20R is
manufactured by Instrument Associates of Memphis, TN.
The i20R front panel and cabinet is identical to the Gai-Tronics IRC3000A
repeater controller, but the rear panel connector layout is slightly
different, and there are some differences between the PCBs. The IRC3000A
sales brochure is here:
www.gai-tronics.com/literature/lmrlit/gtc011105rev11-05.pdf
The IRC3000A service manual is here:
www.gai-tronics.com/products/manuals/43004028a.pdf
I believe that the i20R and the IRC3000A have a common heritage, but which
is the parent?

PL Change
Steve and all...
I have the instruction sheet for connecting a Zetron to an R100 digitized at
home. Also, I have the R100 manual in digital format as well.
I'm not familiar at all with the controller you mentioned - but unless it
does its own encoding/decoding for DPL, you're not going to be able to get
your R100 to make the switch. (That is if your R100 is PL only at this
time. They came one or the other, but not both.)
The unfortunate thing is - I suffered a flood about 2 weeks ago and lost my
computer with the database on it as a result. (Motherboard or power supply,
or maybe both, I'm suspecting at this time...) :-(
I know others have downloaded these items from me in the past - maybe
someone here can repay the favor by forwarding that to Steve on my behalf?
Unless you're not in a huge hurry to get this thing working, Steve. I'm not
sure how long it will take before I can resurrect my computer at home...
Thanks!

Steve,
Anything is possible, but the manual for the i20R controller does not
include specific hookup instructions for the R100. However, it should be a
fairly simple task to translate the instructions for the GR1225 or GR300 to
match the pinouts of the R100.
The i20R controller is a nifty piece of hardware, since it includes such
nice features as CWID and low-battery alarm tones, but it is a bear to
program. Here's what you need to program the i20R:
HVN9085B RSS, currently $310
HKN9217A RIB to radio cable (the same as used for most Radius mobiles)
Motorola Radio Interface Box (RIB - ditto)
6880904Z40 i20R Service Manual, about $25
6880904Z55 i20R Software Manual, about $30

I just got a Motorola i20R controller. Is it posable to wire this to
a R100? Would anyone have the pinout for a i20R?

Hi Steve,
The change requires you to change out both of the processor
chips in
the TX and RX radios. There is also a few part changes of
capacitors
and resistors. Then you need to do the software change and re-
alignment.
It is strongly recommended that you just disable the internal
DPL and
add a Com-Spec 64 enc-dec externally.
