@karst.drenth: Your timely reply is very much appreciated. I will follow your advice and will be ordering YD7432 Reversers as well as an ESU L.Net converter. Also, I am looking into connecting mon-monitored sections through two diodes in each direction as you suggested. So far I have not observed any voltage drop on sections monitored by ESU 50094 Detectors. But that might be because I was measuring on open circuit.?

@Iain Morrison: Thanks for trying to help. The reason I was asking about occupancy detection reporting via S88, is because this functionality is in the specs on yamorc.de page for YD7432 Reverser. According to the page the reverser's reporting capability via enhanced S88 is the same as via LocoNet. The problem, it appears, is in the ECoS which ?does not have galvanic isolation between the track ground and its s88 interface.
