I have (5) MX700 remotes, and (3) original cables that came in the box with the remotes. 1 remote uploads with all 3 cables. The other 4 remotes give the same error message - Fail! 0, with all 3 cables. I have owned, and programmed these remotes for well over 15 years. I have never had a problem until now. Can someone help me understand why 4 of the 5 remotes will no longer upload?

Are you serious? These are 20+ year old remotes. I'm sorry to be the bearer of bad news but electronics don't last forever. As great as URC hardware is (especially the old stuff, which seem to last forever), I'm really surprised those remotes are still going at all (if they were daily drivers).

By analyzing what you said, you have 1 remote that still connects to the software fine. Same cable, same computer, and the other 4 will not connect anymore. Seems to be obvious the 4 remotes are done unfortunately.
I don't think those models had a hard reset you could do, that might allow them to connect again. But doing a deep search on this forum board might revel something. The forum archives go back a long way.

I understand the frustration however. Upgrading to something newer (like MX890 or MX990) will mean getting the software to be able to program it yourself. You need to make 100% sure that if you go that route, the place you buy the remotes from 'will' supply you with the needed software. Or you could be screwed.
Also be warned: time will tell but I wouldn't expect any remote from this decade to go anywhere near the distance those old MX700s did. They just don't build things like they use to... no body does :(

Your best bet would be to pull the remotes apart and check the serial port jack for cracked / cold solder joints. That error typically means that communications is occurring, but there's data corruption in the communications, such as a defective cable. In this case it seems more likely to be broken serial ports.

Has anything else changed, such as the PC or serial port you use for programming? Just want to make sure there's not some possible firmware differences between the remotes that could explain the issue.
