The DB-9 on your set may have the same kind of interface, and some older sets even had info in the user-manual for this stuff (no more, though).Īlong the same lines. Their site also has a newer 2009-2010 command spreadsheet, but it is totally inaccurate for the 2010 set I have here. I found a fair bit from googling about, including an outdated mostly-correct 2008 command listing from Samsung themselves. But not for the 120Hz controls.Īnyone else here got a 120Hz Samsung and want to play along?ĭescription: Linux C-program to issue serial commands to Samsung TV. Thus far, I've figured out mappings between menu items and serial commands for most stuff. What I want, is a way to easily enable/disable that functionality, without having to navigate so bloody deeply through the menu system each time. the TV has "120Hz" refresh, and a few heavily buried menu items for controlling the frame interpolation functionality.
Here (attached) is a small C-program that I wrote, for sending commands to it over a USB serial adapter (hardcoded pathname for now). It consists of a 1/8" stereo mini-plug jack. The port is labeled "service only" or some such drivel, previously known as the "ex link" port. This link is what I used to find all the commands.I've got a new Samsung LCD TV here, and it has a serial-port on the back that can be used to control some functions. Below is a list of items that you can use for commands: Power on: \x08\x22\x00\x00\x00\x02\xD4 Just make sure to change the port below if you do that (after the IP). I used port 22 but you can adjust this if needed. Once everything is hooked up and you can reach your device on the network (default for these devices is that port 80 is open so you can reach it in your browser), you’ll want to make sure that your TCP device is set to TCP server. As I like to keep all my configurations on my PFSense, I switched this to DHCP. The TCP to RS232 that I bought had a default IP of 192.168.0.7 and admin admin for username/password.
(optional) Since I have POE on all my switch ports, I also bought a POE splitter here. This port looks like a headphone jack (3.5mm) but is indeed RS232. The main reason I did this was to make sure my TV stayed off the internet to keep the ads away/data mining. I am able to adjust volume, HDMI, and power easily. Didn’t find any documentation on the site so wanted to help out anyone that is thinking of a similar setup. Just making this post about how I added in my Samsung TV to HA.
