JP1 Remotes

Soldered a pin header into an older urc-7200b00 (Cinema 6) with the hope of having a second jp1 device that I could experiment with impunity on.

The Interface check passes, but when the download is started, it reports "Bad Checksum" expected $44 $BB but found $41 $BE"

It does get enough info to id the remote as a urc 7800-6800.

Any wisdom on this error? I have rechecked the solder joints and they appear to be good and well flowed.

Try doing a 981 reset and see if that clears it. If it doesn't, check your soldering again. Did you use flux? If not, re-do it using flux this time.

Btw, the URC-7200 is a Cinema 7.

>> 981 Reset <<

That did it! Thanks!

Your catch exposes the fact that the battery covers on the Cinema 6 and Cinema 7 are identical and obviously got swapped somewhere over the years that I have had both...

...plus it also exposes the fact that it is probably not a good idea to put the only part/model# for a device on a removable component ;-)

Thanks again,
