I just purchased a OVA 6131 modified that is working great and can control my Echostar 301 and 510 sat receivers individually. I had to change the address of the 510 to 2 but other than that, a painless setup.

I have a 6012 that I would like to keep around but am having problems getting it to work. I changed the CBL key to a second SAT key but I can't get both sat's to program. I can get the 301 programmed to either the SAT or CBL key with code 0775 but when I try to put in the 510 with 1005 or 1170 I get an error flash from the remote light and can't control it.

Any ideas. Should I set the 301 to address 2 and then the 510 to 1 and try that or am I out of luck? Out of curiosity I set the 510 to address 3 but still no luick.
