<{POST_SNAPBACK}>Hi Richard,
Thanks for your reply. I have tried various configurations.
The very basic system is having the Hornby Elite working straight from the box, that is no computer, no EB3 circuit breakers, no additions whatsoever.
TH BD8D board from Oaktree can also be used as "stand-alone". It has a seperate 12v DC regulated Power supply
One track supply from the Elite is connected to a diode bridge, which is then connected to the BD8D
An LED is connected to the corresponding LED terminal on the BD8D
The LED stays on whether a train is on the track or not.
That is the very basic configuration but the result is the same if the BD8D is connected to the IO48, through the supplied USB interface to COM4. The Elite is on Com5. TrainController 5.8 shows the block "occupied" at all times, the LED on the BD8D stays on regardless.
OAKTREE are unable to come up with an answer but are sending a second BD8D to try.

OK - now I understand. You cannot get the detector to change state - even though nothing is on the track, it is showing "occupied" / LED is on. Sorry, I mis read the first time.
just checking as I don't specifically know the Oaktree detector.
Without knowing the circuit the only comment I can make is that if it works with DCC it will certainly work with the Elite, and should work with the select, so the brand of controller will not be an issue.
to eliminate the ontroller as an issue... I'm guessing it is not fussy about power type but needs SOME voltage at the track. try it a with a DC controller turned to about 1/2 or perhaps with nothing but a 9 volt battery connected to the isolated track section you are connecting the detector to instead of a DCC system.
