I appreciate your answers but maybe I'm not clear describing 
the information I am/we are looking for. 

Some 16 pin radio models appear to have programmable rear 
connector pins while other versions of the same type/style 
radio do not. At least the accessory pin programming option 
doesn't pop up in the rss or mrss software. 

The list might be related to what is known as the logic 
board installed in the radio. 

So...  Back to Square One:  Has anyone compiled a list of 16 
pin jack I/O functions available on the various mobile radios 
mentioned.  Or the acc function options based on the installed 
logic board? 

I'm sure there are default logic pin programming assignments 
for the rick cos/cor and tx functions.  Are they the same 
pins used from the m120, maxtrac, gm300, radius? yadda, yadda. 

I have versions of all the ricks including the I20 and I50 units... 
of which I'd like to see if someone has charted all the standard 
functions used by these radios for rick, tone remote... etc. 

(Pin 8 is the standard COR or TX line function type thing)

I have enough Motorhead service manuals to probably reforest 
Nevada so that's not what I'm looking for.  Yeah I could take 
the time to sort up a list myself but why if someone else has 
already done it. 

So.....  anyone know if a practical list of the accessory plug 
function programming by the more common radio models has been 
done and made available on the web..?
