Hi Charlie,

The typical rear terminal connections allow a 
local mic for base station operation and 
probably some type of remote (dc loop current) 
control.  You'd need a standard DC remote to 
use the line terminals. 

If you get a standard Motohead (motorola) 
desk mic, the color code is as follows. 

Mic Hi = Brown
Mic Low = Shield 
PTT = Green 
Mon = White 
Gnd = Black 

PG = ? (I don't remember or it may be an option 
terminal for things like an F2 frequency change) 
Empty = (coffee cup refil) :-) 

LN- = DC remote loop current return
LN+ = DC remove loop current send

The dc remote loop current is directional (polarized) 

cheers
