Just got one DCS-RC modified with the PBW and replaced on the layout. Works perfectly!
I found the underside pins did not need any trimming, and there is ample clearance inside the RC cover for the PBW board. Pretty slick.
I tried it on a couple of PS_2 engines, one on a t'table track and another in the adjacent yard. Both sit dark and quiet until started up, and I don't power these tracks until needed; well after the main TIU WD signal has come and gone. The green led on the RC blinks at a frequency of just longer than once per second. All good.
Thanks Stan and grj for a nice little add-on.
Cheers,
Rod
