Thanks to all of the help in my DCC question thread (
https://www.therailwire.net/forum/index.php?topic=35873.30), DCC implementation started last night.
Here's the overall setup.
There's a shelf (one of the Rubbermaid "extra shelf" wire ones from Lowes), supporting the PS2012 and DCS200.
Then there's a UP5, plugged into one of the ports on the DCS200. It's screwed in, and probably just a temporary location until more construction happens.
That's my throttle, hanging by the plug and with it's "extension cord" wrapped around a pair of cup hooks. Don't worry, I don't plan on leaving it hanging like that.
Power distribution is done on a board that lives on the shelf behind the DCS and PS2012.
Here's a closeup of the shelf.
I went with a wire shelf so I could route cables through it, and also for better airflow.
And here's the quick board I put together to do the power distribution.
Power from the DCS comes in at the top left, goes into that terminal strip (there for quick disconnecting), and then into the bottom one, where it's split into 4 different sub-districts. The PSX units will come off the lines to the left, but right now, I just attached the layout power directly (since only the equivalent of one whole sub-district currently exists.
I'm going to work on mounting a power strip to power it all in a more organized way this weekend, and then mount up the UR92, nice and high up.
