Hi all,
We just got back from a short vacation and am in the process of moving our office. Our phone company messed up our DSL lines so we will not have those installed until at least Wednesday. I am actually using a friend's connection since they also messed up the internet at my home. Man I hate Qwest. So I will try to answer questions as best I can here but I may not be able to answer any follow-on questions until Wednesday or Thursday.

We had a production glitch with a new revision of the Igntion Cutoff and we are having problems with some JR receivers. I hope to have this resolved by early next week. As far as the electical connection between two receivers, there is a common ground connection but it is filtered. The power from each receiver is diode isolated so you will not get any back-flow of power if you loose a battery on one receiver. I hope this helps.
