Ive got a Samsung 75" product code : QE75Q900R (product codes may vary in other countries, but should be similar elsewhere in the world)

Im controlling it over IP via a Savant control system.

The IP control works fine, but im having trouble with the Wake On Lan (WOL).

The WOL dosnt seem to work from the Savant control system or when sent a WOL packet from my laptop, unless the TV has been off for c. 5 minutes.

Eg. if you turn the TV on, then off again it wont respond to again with a WOL packet for c.5 mins, if a WOL packet is sent it just ignores it, but after about 5 minutes it will accept them again.

Any ideas why this might be and what can be done about it ?

Is it preferable to control these TVs over RS232 instead ?

I'm probably wrong about this, but I always put down stupid stuff like this to young engineers who don't understand the ramifications of what they're doing.

Like back in the IR-only days, when Samsung TVs didn't yet have discrete input commands. A series came out that did not switch to TV when you'd hit channel up. At that time, we needed some command, any command, that would always go to some particular input. Usually we'd hit channel up -- the TV would go to TV reception -- then INPUT as many times as needed to get to the input we wanted. A dumb answer, but one that was simple to implement in a remote macro. This was taken away in that series. Instead of changing to the TV tuner, you'd get the message "That function is not available here."

If it consistently works this way, you might have to accept that it just won't do what you want it to do, and go with RS232, as you suggest.

Is there any other command that will turn it on? Again, for remote control macros, we'd sometimes have to send OPEN then PLAY to a DVD player because these were the only commands that would always turn it on and never turn it off.

Can you edit your driver? What happens if you send the power on command without the WOL?

As for RS232, good luck with that. Others have told me it works fine. But when I tried to use it on a frame earlier this week, I couldn’t get anything to work. I think in my case it was an issue with the tv. I think Samsung quality is dropping quickly.

I haven’t worked with Frame, but I’ve had success with RS-232 on other models. Note that a few models need a dongle that is available through distribution.

FYI I dont think you have a frame TV if its a 75". AFAIK the frame maxes at 65. YOu mentioned a model number that seems like its a QLED Samsung.

ANyway, that shouldnt have any bearing on your control issues. Art mode on an actual frame can be a little tricky but other than that IP control of them has been bulletproof.

That's a Q9, not a Frame TV.

Samsung uses an Access Token for control. Does Savant not have and option send for the Access Token and store it? If it doesn't store the Access Token in the controller, maybe you could have a button to send the Access Token to the TV, but then that would require the use of the factory remote to accept the control.

That, or you need to go into Advanced Network Settings and turn on option to allow control?

All odd though since it DOES work for a while.

Appolgoies, it is infact a Q900R and not a frame,



The workflow for connecting Savant and the Samsung IP TV includes sending the token request and storing it. Once done the IP control works absolutly fine. The issue seems to just be with WOL, if the TV has been off for >5 mins it works. If the TV has been off for <5 mins it dose not. Do you know if there is an IP command for "TV ON" i could send at the same time as the WOL command ?

thats the new 8k Q900R series

I am trying to figure out how to send the "token" from RTI,as there driver instructions are still in infancy stage.
Use a sample file?
The RTI instructions said I have to use serial/Mac ID for WOL to work. Not IP address.

As i understand Samsung use the Mac address and IP address the same as the Sony TVs do. The IP is for commands only, and the Mac is for WOL only.

The process of linking any control system / computer to the Samsung TVs i believe first requires getting the control system to send a "request" command to the Samsung TV. The Samsung TV will then display a message something like "a 3rd party device is trying to control this TV, do you want to allow" you click select on the TV using the TV remote, then the IP commands will work on the TV.

I believe for WOL, no prior auth is needed.

I worked with URC on a bug I found with the Samsung IP driver for Total Control.  When entering the MAC address into the Total Control software it wasn't always accepted correctly which caused issues with the power on (WOL).

I found that on larger jobs where I had more than 2-3 TVs I was copying and pasting the MAC address from a spreadsheet which created a carriage return at the end of the MAC address.  This was a hidden, but wasn't parsed correctly so the MAC address was corrupt.

URC fixed this in an update and now the MAC has to be formatted correctly to be accepted.

I know you are using Savant, but maybe something similar is happening?

I checked but couldnt see that there where any blank spaces or formatting issues with the MAC address, out of interest when you where having the issue where they intermittent, or happening all the time.

Also do you know if there is an "ON" IP command, that i could send allong with the WOL packet. My thought is that if the TV has just been turned off the network card may still be awake and respond to the "ON" IP command, where its not responding to the MAC WOL
