Programming new remote for B&K AVR507

I am not sure if the software you have is the full URC software or not. It is is, you can probably create what you need. If you have access to the database you can get the commands from it. demo.mrf is just a blank file that needs to be programmed. Select Program, then IR Database. Device is the name of the device as it appears on the remote (Like Audio), then select IR Data from AUDIO, then Under Brand select B&K and then the appropriate model. Give that a try. If you have the full software, it should work. If so, you can add other devices like your TV and Blu-Ray player. Or you could learn data from their remotes. I do not have a 507, but I do have B&K models from the URC database, including the 507, that I could send you. Just do not put your main email address here or you open yourself up to potential unwanted spam.

Are you using a USB adapter to connect your remote to your computer? Mt remote arrived two days ago but I need a serial port to USB adapter to connect it to my laptop for programming.

I use an old Belkin one. Not all of them work correctly, so you have to be a little careful. Also, I run mine on XP - not sure if the software runs on W7 or not. The MX-900 uses a USB connection.

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.
