That series (as well as 700/800) were always a pain to connect and had high corruption rates wiping out the remote bios...sometimes you could recover the remote (not the programming), other times the remote would be toast.

We no longer support the remote for new clients and greatly recommend updating to a newer remote (many new devices can not be reliably controlled by that series of remotes either - Dish Hopper, Xfinity X1, and others)...even when using their universal browser and inputing direct hex codes.
