SantaFeFan posted:Sorry Kevin, only so much one can do with 3rd party products. The DZ-2500 connections don't provide an easy to monitor signal. The comments from Chuck help, and you can use a relay-you only need +5 to trip the STM2, no need for the -5v source.
So the STM2 inputs respond to +5 v for Thru.
And 0 v for Out?
I wondered that since there are no LEDs to light as to the STM2.
I have often wondered if there could be a bit more technical data in the manuals. They are written without any tech detail at all...which I think is traditional for toy trains.
But, in these times of high tech model railroading, it would be great to have a page at the end of the manual with some I/O electrical specs. Or...maybe on the website...more technical detail in a service link to current products.
