I've gone back to square 1 here to try and get this working.

I've got rid of my program and am just using the one supplied with the module.

I've uploaded it to my QM-RMC. (Was using an AV2)

I made the cable myself, pins 2,3,5 -> T,R,S tested it with a mm several times to be sure.

I've also tried changing the baud rate to 115200 as previously suggested. It's now back on 9600.

I think the key thing here is that I am getting absolutely nothing coming into SIMPL Debugger on the Rx$ of the com port that the Ex-Link is connected to.

The TV should be spurting something out regardless of what I am sending it no?

If you downloaded the UN55ES8000 module from the website. It's a straight through cable.

Did you load BOTH the Hardware & Logic modules into your program?

Did you make your own cable, or use a Samsung cable?

I used the UN55ES8000 module on a 46" with a Samsung cable plugged straight into a MC3 and it worked perfectly. ...wasn't a long run.

Thanks,

But does this actually apply to me? The pdf regarding the module I am using has no mention of injecting power...

I am connecting directly from an AV2 to the EX-Link port.

Have I missed something here? When others connect Ex-Link do you not connect directly?

Hi!

Check this info about ex-link

Specially this!!!:

"As the TV uses 3.3V TTL levels, the serial input/output has to be converted to/from TTL levels to RS232 levels (~10-15V). Thus a level shifter is needed. But most computers today, doesn't have an RS232 port, so you also need a USB-to-RS232 serial adapter (cable). Thus its a definite advantage to buy a pre-fabricated USB-to-serial converter using 3.3 Volt TTL levels on the serial side. Common one to look for are based on the PL2303 and FTDI chips.
WARNING! RS232 levels are up to 15V, which can cause seriously damage at your TV!"

Hi,

I hope someone can have some patience and spoon feed me through this as I have sat here for hours and have got nowhere. I am guessing a bit so please let me know if I am doing something stupid.

Firstly this may all be down to me using a module that may not work as I can't find my TV.

I have a: UE55ES7000
Closest I can find is the UN55ES8000

I've made up a cable for EX-LINK control using the diagram in the module pdf

(integrated_partner_modules/help_files/959/samsung_un55es8000_v1_0_help.pdf)

Tested cable with multi-meter, seems fine.

I have set the value of the RS232 mode to Debug.

Tried a basic test with the module set up like this:



I'm getting nothing in debugger on Samsung_Rx$ and the TV responds to nothing…

Any help appreciated.

Thanks.
