Hi all, hope you can offer some quick help. Just wrapped a job tonight and only thing left is to teach the MX850 the IR codes for a Cox Cable Cisco Contour box. At first it looked great as the MX850 was learning the IR commands but unfortunately after testing not a single one worked. The MRF260 flashes and even aiming directly at the cable box doesn't help.I tried all Cisco codes in the MX850 program and no luck. Tried long and short holds, close & far away, fluttering too. Really appreciate some help on this one.
Thanks

Try the Scientific Atlanta code sets...starting specifically with the 8300 or 3250 HD series.

Make sure your mx-850 software is up to date via live update.

Go to the ir database, use Comcast Xfinity or X1 ip code set. Cox licensed the Xfinity X1 system from Comcast and branded it contour 2.

Ir and rf seem like they are the best choice from the database but the ip codes work best... They work ir from the mx-850 and rf from a urc Mrf box.

Thanks! Unfortunately none of those worked. URC tech support was surprisingly disinterested and not very helpful as well.
Best I can say is everyone keep an eye on these Cox Cisco 9865HDC boxes for incompatibility problems.

I have no idea if it will help but you can try learning the codes directly into the MX-850 with it NOT connected to the computer. I remember needing to do it years ago for Scientific Atlanta cable boxes and problems with the 58kHz IR.

If you want to try...

Use the software to name all the buttons in the device. Press the Menu and Enter buttons and hold them. (It's just like the old MX-650 but you have to hold it for a while.) Go into the learn section and manually learn all the codes. Upload the remote back into the software and go from there.

Go luck.

People here have told us to quit selling the MX850, so it's no surprise that URC isn't interested in the latest problem with them.

I was given this advice despite the fact that I was modifying a customer's existing remotes, not selling him a thing. I was advised (here) to sell him three remotes when they needed a change of TV brands and nothing more.

The Codes do not and will not work reliably with an MX850 (nor 800/700/650/600/500/450/350); the Comcast codes are longer then the devices can record.

You "May" be able to inport the Hex codes but there are no guarantee those will work either.

You should consider selling them a new remote as there are many new devices currently available and coming that will not work with remotes of that vintage (the remote design/technology/protocol is over 15 years old now).
