Re: EV-100, Fiber optics sensor power and signalling
Thank you for participating in this discussion.
Your suggestion is very interesting, but *BUT* we are attempting to get
something close to a MONITORED TRIP RECORDER in use ASAP, at the
*LOWEST* possible cost and as simple as possible.
Of course, the use of a *STANDARD* board on what we will define as the
*STANDARD EV-100 BUS* will allow us to swap-out an older card for a
newer card, at lower costs *LATER* at some future time.
You have a lot to contribute to the EV-100 SYSTEM BUS at this time, and
I hope you will!
