#200446 Anybody have rs232 commands for this model? Thanks |
#200460 They are definitely in the manual for the 55' version, just did one this week. However we had problems getting the screen to turn on with RS232 or IP, in the end the integrator was going to swap the screen out for a new one as we thought it might have been faulty. These are the codes we were using, hope it helps. Power On - xAAx11xFEx01x01x11 Power Off - xAAx11xFEx01x00x10 |
#200462 I have two of these on a job at the moment and I'm having the same problem as Charlie on both. They turn off but won't turn back on, I've tried ID FE, FF and 00 turned off all the power saving options and turned on network standby but it still doesn't turn on. The serial port continues responding to polling when the display is off, so it's not that the serial port has been powered off, it even responds to the power on command in the normal way, but it doesn't turn on and when you poll the power status it reports as off. Also checked the firmware on both and they're up to date. Anyone have a fix? |

Set the displays to an ID of '1' in the OSD and set the strings/modules to use that address - should be golden. - Chip |

#200548 'Thanks all. Worked!' What was the fix? Thanks, - Chip |
#200907 Just been back with these displays. I had to set 'Network Standby' (in System / Power Control ) to 'Off'. That caught me out, I thought it needed to be ON - as in 'keep network port ON when the screen is in standby', but it's actually 'turn OFF disabling the network port when the screen is in standby' ?! This was for serial control btw, Apart from that, setting the ID on the screen then using that specific ID in the commands (not just the broadcast ID) worked fine. |
It happens, that I get my new 32″ Samsung TV – model LE32D550. Like most of new Samsung TV’s (if not everyone) it could be connected into the LAN. Of course, one of the first thing I do when the network cable was connected was port-scan.
55000 is used for remote control over network. There is application for iPhone and Android smartphones (unfortunately only these created by Samsung) to control TV through WiFi. I did some research, and now I understand the protocol quite well.
When connection on port 55000 is established, remote control must be authenticated. It sends datagram.
And the meaning of this bytes.
I don’t know the meaning of the string above, my TV is accepting any string in here, but I suggest to use this particular one just for compatibility reason.
Payload starts with 2 bytes: 0x64 and 0x00, then comes 3 strings encoded with base64 algorithm. Every string is preceded by 2-bytes field containing encoded string length. These three strings are as follow:
- remote control device IP,
- unique ID – value to distinguish controllers,
- name – it will be displayed as controller name.
TV reply us giving following datagram:
It means:
String content is always iapp.samsung or iphone.livingroom.iapp.samsung. Meaning of these strings is unclear, I suggest to not compare it with any specific value during response parsing (maybe other devices using another values).
Payload is one of the following:
- 0x64, 0x00, 0x01, 0x00 – access granted, you can now send key codes and it will be executed by TV,
- 0x64, 0x00, 0x00, 0x00 – access denied – user rejected your network remote controller,
- 0x0A, 0x00, 0x02, 0x00, 0x00, 0x00 – waiting for user to grant or deny access for your app,
- 0x65, 0x00 – timeout or cancelled by user.
Now you can send simple datagrams containing key codes.
It means:
And the payload is:
TV response will be similar to authentication response, but with different payload data. I will not describe this data detailed because I wasn’t investigated it much.
