Hi

Just got these details from a user. I assume the last 2 characters are the OBCs, can we get the protocol/device from the rest ?

CH Up 4F5830CF
Ch down 4F58B04F
Vol Up 4F5850AF
Vol Down 4F58D02F
Up 4F5808F7
Right 4F58C837
Down 4F5848B7
Left 4F588877
OK 4F5828D7
Menu 4F58649B
EPG 4F58EC13
Exit 4F58A857
Return 4F5834CB
ChList 4F586C93
Mute 4F5804FB
Power 4F587887

Hi Allen, there isn't enough to get the protocol from this, BUT since it is 32 bits it would probably be some sort of NEC and since the last 2 bytes are function and complement, that is even more of a clue.

.
Device, Subdevice, OBC, Complement.
4F, f8, 30, CF be Channel+

Read as LSB, that would be
242, 26, 12

When I look at that combo, and compare it with the device upgrades we have a NECX2 upgrade, with device 242, subdevice 26, with a matching CH+ OBC in our upgrade area, thanks to Mr. alanrichey,

I think this Samsung SMT-C5050 upgrade should match up.

Check the last value in hex, against the hex for each function. I'd do it, but am late for an appointment.

Thanks for that, I'll tell him to try.

Hi Allen, if this does turn out to be a NecX2 signal, then this should cover most functions. Please note a few buttons need to be changed.

His Return = Last Channel

Power, Menu, Guide, and ChannelList will be different obcs.
Power 30
Menu 38
Guide 55
Ch_List 54 (was menu in your upgrade)

Everything else lines up nicely.

Thanks. In fact the C5050 Power command is already 30 so he should see a reaction. Fingers crossed
