create a system under the application task If your serial port, it's anything other than/dev/ttyS1 use number one it is set correctly.ġ. To check that create a system task to check your settings using the number 5 below. To use the RS232 commands on the serial port DMP must be defined on IT and be Sorry, but the SharpUSA site is down so I can't get your particular model, but here is an example So, is it possible to include a space and a CR in a text string to be sent by the DPM and have successfully sent the entire string? The TV does not accept the command without spaces and the CR. If I include a space anywhere in the order the DMP sends nothing. When I connect the DMP to my PC and send only the updated command in shape without spaces or CR the DMP sends the text correctly in PuTTY. I ran the system task to control non-DMTech screens, then I created a system with the following command POWR0 = rs232.tx_str task Using PuTTY, I can control the TV from my PC through Putty and the command is executed as soon as I hit Enter (CR). The format is 4 digits of order, of 4-digit parameter followed by a carriage return.įor example, the power off command is followed POWR0 of 3 spaces (all figures parameter are mandatory, so 3 spaces) followed by a carriage return. The Sharp TV is looking for text control rather than hex apparently. The corresponding US model is either the UN55HU8700 or UN55HU9000.I try to control a TV Sharp (LC-42D65UT) through DMM system tasks. Daniel at the Loxone forum reported success with his UE55HU8580. Don't add any more 0D to any other string, just power it up with this string and then use the standard strings for all other commands.Ħ. When you send the power on command, you must add a CR (thanks to Daniel at the Loxone forum for this). You may actually disable RS232 control if you do some of the things that you find in the net, such as activating Debug. No changes in the Service Menu are required, it works straight from the box. For some reason, I coudn't make it work with any terminal software I tried (TeraTerm, HypeTerm) and even Eventghost. I am using a Philips Pronto RFX9600 extender and it works fine with 9600, 8, N, 1 settings ģ. I tried with a B&B 232LPTT元3 and it doesn't work Ģ.

Just to share my experience, I have been successful with RS232 control of a UE55HU7500LXXC, euro model, apparently the same model as the US UN55HU8550 version.ġ.
