Programming new remote for B&K AVR507

I appreciate all the responses. My replacement remote is programmed! I picked up a USB to serial port adapter which works well with windows 7. I had to re-designate my ports which took some time to figure out but it was easy to do once I did a little research. I'm very happy that I was able to find my original B&K SR10.1 software as it had all the original programming in the software, so once I downloaded the default file for my 507 to the remote it looked and operated just as the original remote did when I purchased this fine receiver 8 years ago. Now that I have all of my remotes programmed into my new (old) MX-700 I just need to remember how to build macro's.

Great news. What usb to serial did you get. My Belkin does not work on W7.

Its a generic brand ordered from cables for less. Mine didn't work right away either. I had to play around with my comm port settings through device manager. The editing software for the remote only goes to comm6 and the driver was installed on comm 10 so I had to go into the comm port numbered 10 and change it to comm 6. You may want to try and play with your comm port settings a bit if you haven't done so already before purchasing another cable.

Thanks for the information. I have checked the comm port setting. That is a common problem. I think my problem is that there is no W7 driver for mine and the XP driver does not work correctly on W7. I will look at the cables for less one. Thanks.

The Cables for less adapter worked great once I downloaded the drivers from the Cables for Less website. The drivers that came with the device are old and the one that W7 loaded did not seem to work. Up and running on W7 now for $19, running on 2 different W7 system. Thanks.
