Hi Anthony,
I'm pretty sure it does provide +5 to the antenna. I didn't understand what I
was seeing for quite some time yesterday, and it seemed like it was telling me
it didn't see an antenna. So, I pulled it off of the splitter and put it onto
my second antenna. After a bit, it saw some sats so I think it was driving it
fine. I put it back on my splitter and things were fine as well. The thing
that was confusing me was that the unit with the green ON light is the one you
need to hook the PC to. Use the J8-Diagnostic connector and Stewart's RS-422
to RS-232 adapter scheme.
I didn't try it, but I assume a USB dongle wired appropriately would work, as
well. As I'm out of serial ports on the server and had to turn on the laptop
to interface this, I'll probably try that experiment soon.
Bob

Let us know how this is progressing. I am waiting on a TNC connector, so can't
get mine up and running this weekend as planned. I'll get my power supply
sorted out and see if I can get SatStat connected.
Do you know if the GPS input provides a 5v bias to drive an antenna?
Anthony
