Im not sure if i missed it in the thread but are you able to show the checksum calculation formula it appears to be a completely different formula from commercial grade screens.

Thanks,

I'm not sure how this will look on the forum, hopefully it shows up correctly:

=DEC2HEX(HEX2DEC(100)-HEX2DEC(RIGHT(DEC2HEX(HEX2DEC(MID(D4,1,2))+HEX2DEC(MID(E4,1,2))+HEX2DEC(MID(F4,1,2))+HEX2DEC(MID(G4,1,2))+HEX2DEC(MID(H4,1,2))+HEX2DEC(MID(I4,1,2))),2)))

I decided to share what I have that partially works to see if it helps anyone. Please feel free to contribute if you see something wrong! The script works great sometimes and after the TV power cycling it may or may not work. If it does work, it works for the entire time the TV is on.

Code is here (work in progress):

I'm able to turn ON the TV with both the Power-On and Toggle commands, but unable to turn it OFF. Neither Power-Off nor Toggle seem to work.

TV: UN60F8000
Power On: 8, 22, 0, 0, 0, 2, D4 (works)
Toggle: 8, 22, 0, 0, 0, 0, D6 (works as Power-On only)
Power Off: 8, 22, 0, 0, 0, 1, D5 (doesn't work)

Any ideas?

The link doesn't work for me. I'm trying to gain control of the Smarthub features on a TV.

I have been using your code set for several years (THANK YOU!) but the new (Samsung 8000 & 9000 Series - 2016) models no longer allow direct navigation to Netflix or Amazon apps. Have you experienced this issue and if so do you have a work around?

Piggybacking on your post, I'm expecting a Samsung 2017 MU8000. Has anyone tried Duct Tape's codes (Thanks!) on the 2017's? More specifically the KEY_xxx ones, which I assume are the Smart Hub ones?

Dormant thread?

Here are the (only) commands that worked for me on a MU8000:

Power Off 08 22 00 00 00 01 D5
Power On 08 22 00 00 00 02 D4
Enter (OK) 08 22 0D 00 00 68 61
Exit 08 22 0D 00 00 2D 9C
Return (back) 08 22 0d 00 00 58 71
Menu 08 22 0D 00 00 1A AF
Info 08 22 0D 00 00 1F AA
Up 08 22 0D 00 00 60 69
Down 08 22 0D 00 00 61 68
Right 08 22 0D 00 00 62 67
Left 08 22 0D 00 00 65 64

BTW, the "KEY_..." set did not work for me.

And don't make the mistake as I did of adding a command termination suffix (0D 0A): in my setup, it made things erratic, not to say totally non operational.

Anyone found a code to activate Ambient mode on the 2018 models? There is a code for Art Mode, but that just pops "Not available" on screen when used. Presumably there is a different code to activate Ambient mode. The idea of engaging a passive mode via a button makes no sense so I'm trying to engage it automatically when the TV is turned "off".

I wanted to bump this threat because I saw anther blog post that had some RS232 codes for Samsung that look way different:

[Link: support.justaddpower.com]

For example, Power On..

HEX: AA 11 FE 01 01 11

vs the one in the spreadsheet:

08 22 00 00 00 02 D4

Or do we need to convert the raw string to HEX?

those are both examples of hex strings.  the example codes they show are for video wall displays.  the codes in my document are for exlink models.

here are the examples from justaddpower for exlink:

as you can see, the codes are the same

ambient mode codes:

Art Mode On         08 22 0b 0b 0e 01 b1
Art Mode OFF       08 22 0b 0b 0e 00 b2


I'll add them to the document when I get some time.

Thanks. I have several ME Series in my house (bought them from a business) and they have RS232C input/output and use different codes. The back of the TV wheer the 3.5 mm jacks are is labeled "RS232C"

[Link: support.justaddpower.com]

I confirmed these RS232C codes work by using the GC-100 plugged in to my TV and then using the iTest utility to send the RS232C codes (e.g.,
AA 11 FE 01 01 11)

This is what was causing my confusion. Now, onward to find a list of all available RS232C codes.

None of the RS232 Ex-Link codes work on my ME Series.

Appreciate the help.
