The HDR T2 code set 1 uses 1000hex as the address which isn't a particularly good choice.Ah, I see it is being naughty and uses a code set that it shouldn't be and which clashes with the Humax code set 1.
Is there a central authority allocating NEC format codes?The code sets are allocated in groups depending on device type. A switch should not be using a code set designated for use by a PVR.
I imagine it depends whether the particular manufacturer is a member of that particular club (at great expense), otherwise it's a free-for-all.Is there a central authority allocating NEC format codes?
