Remember that commands must be entered in hexadecimal format. These are the commands for an NEC V Series LCD:

On: 01302a30413043024332303344363030303103730D
Off: 01302a30413043024332303344363030303403760D

Could you please elaborate on this? It looks to me like it's possible to turn the TVs on/off via a USB to IR adapter and pasting this code? I hope this is the case, it'd be a great feature!

Mike,

We never tested an IR adapter, but we did test a USB to Serial Adapter (more on that in the announcement post).

The codes above are unique to the NEC V Series, all brands and series of Displays will have their own codes.

Let us know how you make out using an IR Adapter!

Hi Robb,

Would you know where I'd be able to find the power on and off codes for an LG LN5300? I used the manual but could only come up with the following codes:

ON: 6b612030203031480d0a
OFF: 6b612030203030480d0a

I wasn't able to get these working but I feel they're close...

Thank you!

Hi Ryan,

It may be best to reach out to LG on this one to inquire what the hexadecimal codes are.

Thanks.

Neal,

Thank you, I'll contact them and see what I can come up with!

Should be in the manual, but not in HEX. See below for my codes for one of the Flatron models.

Any luck with the LG codes? I have a 60LB5200 and I'm trying to determine if I can control it via hex codes. Also, which input on the display should I use? This model has USB inputs, but the manual only makes reference to using USB for storage devices, not for control of the display.

On a related note, if this display is not suitable for hex-code control, are there recommendations for displays (LG or other) that are well suited? I'm looking for a 60" display.

Believe you'll need a model capable of R232 (Serial Port) control. I use a USB to serial converter for our models here. I haven't looked up the model you specify, but you'll most certainly need a commercial grade monitor. My only experience is with the Philip's BDL line, but we like them so far, and I'm positive they have a 60" model. Hopefully others will have some input for you as well :)

I find it funny that new-model TVs would still use RS-232 (but that's ok, it's not a problem). Any recommendations for a good place to buy Philip's BDL monitors? It doesn't seem to be the sort of thing one gets at a BestBuy ...

The display is part of a system we're setting up for a non-profit group, so our budget isn't huge.

You might check Provantage.. we've used them a couple times and been happy. I recall it was difficult to find people who sell business grade models to just the average Joe who needs a single one. :/

Sharp LC-60LE650U

On: 504F5752312020200D
Off: 504F5752302020200D

Before the power on command worked I had to turn off Engery Savings through the menu on the TV and run the command "RSPW1   " from a serial connection. The ASCII codes were available on Sharps website under owners manual. I just converted the on and off commands from the ASCII codes provided to hex. 

ASCII codes for power on and off are
"POWR0   " Power Off
"POWR1   " Power On

There are three blank spaces after the 0 and 1 according to their manual's instructions.

Man , thank you! Quick question what serial connection does the sharp TVs use? Have you had success using and running with the RV Chromebox platform?
I am looking at using the Sharp LC-50LB261u from best buy? Do you see these commands as compatible? Install date is coming up on a short window an I need to make a decision between the sharp or a Samsung model and fig out how to control samsjng via the ex-link ... An I am a newb to this stuff

MyLife614,

I just started to look into Rise Vision and digital signage this week so I am new to this as well. I am using a DB9 Female to DB9 Female Null Modem Cable attached to a usb to serial adapter from Startech with a Windows 7 Laptop for my test setup. 

I took a quick look at the Sharp LC-50LB261u and I don't see a RS232 serial port listed on Best Buy's website or in its manual. Please don't take my word for this and verify this yourself. 

With that being said I believe it won't work with that model of display and I have not tested with a chromebox. I wish I could be more help. I would be interested in what display you end up using and if you are able to get Display Control to work with it. Good luck.

Any Known Hex Commands for Samsung displays?  I'm Back to testing this functionality, I had simply been using the on/off features built into the display but would love to set up the command to generate from the Chromebox. I have the needed serial cables on hand

NVM I believe I have found them! Question I Have set up the Presentation , and have established a connection to the display. I have tested the Off Command and it works. once the information is put in and I hit apply, can I now remove that presentation from the schedule, so it does not show the setting image in the feed?

Which schedule do i used to change the timing on etc? I guess i am a little confused on the information provided in the guide link..... 

Update: Turn off Command work perfect, but It did not come back "on" through the serial command. Anyone else have Experience with Samsungs?

Contacted Philips and they gave me the wrong codes (imagine that..) but I found an SICP manual and these were gold. May work for other Philips monitors, but in particular mine is a BDL4220QL.

ON - 050118021E
OFF - 050118011D

I contacted Vizio to get the commands for our TVs, and they gave me the following, although I'm a bit lost in how to convert it to the proper Hex format:
NEC Protocol, Address 04FB . PWR OFF = 25, PWR ON = 2A. 

Can anyone help me understand how turn this into the proper hex command?  Thanks!

EDIT: Enter is FF. If I convert "25FF" (PWR OFF, Enter) into Hex, I get "050118021e32354646," which looks a lot more viable...

One question-- I notice that most of the hex codes that people have posted end in some kind of terminator (0a, 0D, 0e). Mine doesn't. Is that going to be a problem? 

Also, I got that hex code from an ASCII-to-Hex converter, and I don't think it correctly interpreted the FF. If the "FF" is supposed to be the Form Feed command to terminate the control, that should be "0c" (which solves the terminator problem). That would give me a hex code of 32350c . Would that be the correct interpretation?

Thanks for the help-- this is very much outside of my expertise, and I don't want to brick my TV by throwing a bunch of random commands at it...

Robb, do you think I need to do anything with the address, or will Display Control suss that out? Thanks!
