H6640 exlink port
I would like to read debug data from my Samsung's H6640 exlink port. Is there a way to access it without opening the TV? Does anybody know where is it located?

I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)

Re: H6640 exlink port
I have rooted already (and many thanks for your hard work in this field . But I need a rs232 interface for a home automation project.

Then you need do soldier or patch (in UNKNOWN way) kernel... Unless you want to ONLY read ?rexio8 wrote:I have rooted already (and many thanks for your hard work in this field . But I need a rs232 interface for a home automation project.
BTW why NOT use usb to rs232 adapter?

Re: H6640 exlink port
I was hoping that exlink is easy accessible. But the idea with USB to rs232 is working great - thanks.
One more concern: after the dmesg command I can see several error messages like:
#########################################
[ERROR][CAP:NoSKIP][CAP(19)][TH(pidof:2244)PTH(sh)][U(1010)G(1010)]
###########################################
#########################################
[ERROR][CAP:NoSKIP][CAP(19)][TH(pidof:2244)PTH(sh)][U(1010)G(1010)]
###########################################
is this normal or I have something wrong with my config (I haven't observed any issues with the TV yet)?

Re: H6640 exlink port
It's "normal". From Samsung's point of view maybe
I do NOT receive any PM. Please use forum.
Re: H6640 exlink port
Sorry to bump an old thread, but I have found out, that exlink works on my h6640 tv through the audio out (headphones) jack. All you need to do is enable uart and change the rs232 mode to uart in the service menu. Now I can control my tv through rs232.sectroyer wrote: ↑Wed Jan 27, 2016 1:48 pmThen you need do soldier or patch (in UNKNOWN way) kernel...

Thanks for your awesome work guys!
Re: H6640 exlink port
Interesting. You mind to share details like: what adapter you are using (really RS232 or TTL?), Pinout of the 3.5mm connector, setting for the serial console etc.rexio8 wrote: ↑Fri Mar 09, 2018 3:23 pm Sorry to bump an old thread, but I have found out, that exlink works on my h6640 tv through the audio out (headphones) jack.

Re: H6640 exlink port
I'm using a Nokia DKU-5 cable, prepared according to the wiki (https://wiki.samygo.tv/index.php?title= ... BD_players), so 3.3v TTL here. The 3.5mm audio jack is also connected according to the wiki - well at least I think so, because initially I wasn't getting anything on the serial console, so I switched the rx and tx pins, but I could have interpreted the wiki wrong initially. As for the serial console settings it's also like on the wiki:
Speed 9600
Data bits 8
Stop bits 1
Parity None
Flow control None
I have also found evidence on the net, that exlink works for the H6400 through the audio jack.
Re: H6640 exlink port
Nice find but you made one mistake. RS232 mode needs to be set to Debug Setting UART to ON is enough to enable FULL exlink on headphone jack You will see HUGE difference in a size of output When set to UART exlink (on ANY port) gives you ONLY basic message. Anyway once again good find.rexio8 wrote: ↑Fri Mar 09, 2018 3:23 pm Sorry to bump an old thread, but I have found out, that exlink works on my h6640 tv through the audio out (headphones) jack.
