D11 serial control with patersontech.com usb serial adapter
Just to help any newbs out with directv service. Do yourself a favor and don't mess with getting a used d10-100 receiver. (A scammer is on ebay selling bunk d10-100's currently - ie. "lots of 10") Just get the d11-500 (only $49) from any best buy etc. and use the adapters from patersontech.com. You will need to either have a serial port for each reciever or purchase a usb to serial converter. This does work very well though.
On the D11 you can even set the OSD display time to 2 seconds. The directv OSD is gone usually before the Sage one is, so it doesn't pose much of an issue.
By the time you buy a d10-100, you still have to buy a new access card from dtv for $20. For $49 it's cheaper anyway.
Just trying to post as much of my learning experiences as possible.
