Aha, so you are switching other equipment on and off with the POWER
command. Have a look at the photos section of the Yahoo group to see
the I/O that I have on my digipeaters. There's also a quick hack job
page describing it a bit on the wiki. It's not linked in anywhere yet,
but you can find it searching on "Site Telemetry". I brought the
switched power out of the OT2 and am driving a relay with it. This is
just to make it a little more fool proof, in case someone else tries
to connect into the output. The OT2 contacts are connected directly to
the supply voltage the OT2 runs on, and if someone were to connect
something other than 12 volts to it, the magic smoke might escape.
Hopefully you are thinking about switching other equipment with the
power cord, and not cycling power to the OT2 itself. You'll be
shooting yourself in the foot with that trick.
