So I have encountered an unanticipated problem with this first board build.
All my testing on the BB was done using a momentary pushbutton switch to simulate block occupancy, and I think RTR12 used the same idea. Now with this first board build I was experimenting leaving the BOD contacts connected for an extended time, like a train travelling through the block. I found that when you release the BOD, the red signal goes immediately to green, surprisingly.
It looks to me like the timing sequence starts as soon as the BOD contacts are tripped, instead of initiating when they are disconnected. Thus, when the BOD is opened, the release timings have already expired, and it goes straight to green. Not as we intended at all.
So anyone who is planning on ordering boards using the gerbers posted earlier, better hold off until we get this solved. For anyone who has already ordered boards, maybe see if you can cancel or put your order on hold. My apologies for any inconvenience. Hopefully we can get this solved quickly.
If anyone has any advice as to a resolution, that would be appreciated also.
