A word of caution. In the last three years we have experienced problems  
with the RS 232 interface. We know that wrong messages can contaminate the 
code  in the controller permanently preventing lock. We suspect switch bounce 
or  connect or disconnect while under power.  With the cost of these units,  
efforts should be made to have every thing connected before power is 
connected.  Same on power down. That is why we have a lock detect on the RB 
controller and a  5 minute delay on all units.
Our controller works with all three units, the code for the 405  is  
slightly different. Cash Olsen will be responsible for the sale of assembled and  
tested units. There have been units out there with time nuts including the 
405  for over a year. Results look very good, but again to get the very best 
results  temperature control is a must. With units like this we are talking 
at least an  order of magnitude.
My move has cost a year and I am looking forward to have my GPS up and  
running. Next week is the goal. Antenna is key and the permit process was four  
month. Downsizing is hell!
