Sorry if thsi is in the wrong place - but if I have a list of RS232 Codes for a Device is it possible to convert them into the correcponding IR Codes ?

Thanks,

Jim

More information is necessary. WHat device, and what are you controlling it with, and exactally what are you trying to do?

RS232 can be converted to IR, but it requires hardware. It's not just a matter of changing something in the software.

Xantech makes a piece, but it may not do what you are trying to do.

Hi thanks for the reply.

I'm not looking for a device to convert the RS232 codes to IR Codes.

I've a LG 42LH4000 LCD TV and the user manual has (surprisingly) a detailed section about controling all the TV features using RS232. Unfortunately it doesn't have a similar section containing the IR Codes.

So I was (perhaps naievly) asking if there was a simple way to take a RS232 Code and "work" out the corresponding IR Raw Hex Codes.

The short answer is no.

However, most of the IR libraries here shoudl do what you need.

What specific codes are you looking for and what type of remote and/or control system are you using?

there is NO device that will do what you require.
the Xantech product does not 'convert' the 232 codes to IR, it simply responds to Xantech 232 codes and spits out whatever IR codes you have assigned to it.
your best route is to find out the discrete IR codes themselves, do you have any Hex codes that you can post that actually work for your TV which i believe is an LG?
Alternatively have you looked in the files section of this forum?
i also know you are using a Harmony so testing of these codes will not be an immediate process, let's start the ball rolling.....

@ Thefish -Hi - it's a Harmony 555 and a LG 42LH4000 model TV.

@ makitamark - I've already looked at the IR Codelists and although I may have missed it there didn't seem to be much LG stuff ?

Regarding current LG Hex Codes - I don't have any at the moment but I'm about to dig up my old Plam M100 PDA (LOL) and load a trial URC Program which should I think allow me to learn a couple of codes and dump them out.

When I get them I will post them back and also the "corresponding" RS232 Codes if that's of any use ?

Jim

don't bother with the 232 codes.
have you tried any of these?

You will have to extract the hex code, and somehow get it into the harmony. Not familiar with teh harmony, but someone here can help you with that.

I suggested the Xantech piece based on the vaugeness of the OP.

Thanks Guys - No I hadn't looked there - I'd ignored the "remote specific" areas initially and was looking at the code library downloads etc. so thanks for that it looks very promising.

Regarding getting the raw codes into the Harmony I think that I need to specifically request a custom button/action to be setup using the raw codes I supply and then the support folk create a "Custom LG" TV for me only which can then download to my remote and uit stays in my remote account details etc.

I realised that the link to the convertor device was entirely due to the vagueness of my original post ;)

Thanks again

Jim

I am also looking to send ir codes via RS-232.
I see that that this is not simple and i have a lot of learning ahead of me.
I need to control multiple AV devices via computer. I currently have control via RS-232 for (2) Tascam CD Players, Denon DA-7100 Surround Preamplifie, Christie Roadster 12K projector and more... I use usb to (8) serial port adapter. I also have
AMX AXB-IRS4 Serial to IR box. Looking to control (2) Icecrypt Satellite Receiver STC6000 HD PVR and Sony BDP-S360 Blu Ray Player both of which are IR only.
Am I on the right track? What hardware/software should I look at? Thanks

The AMX IRS4 is not a serial to IR box.. it is an AMX proprietary IR output box that will only work with an AMX control system. If you are controlling via a computer you need to find some sort of 232 box such as the xantech piece listed above or there are LAN IR boxes on the market that you can load IR libraries into and then issue IR commands via IP commands to the box.

Read the rest of this thread. You will see in there that it is stated, there is NO product that does this. It's like translating gear ratios into English, and using gear teeth to do it.

IR codes are groups of codes (256 per group) which a manufacturer has used, choosing according to no established principles which codes do which functions. 232 codes are a different style of naming commands, which the receiving device interprets to do what has been commanded. There is ZERO relationship between the two things.


I cannot comment on the hardware you have ,but one of the Xantech devices mentioned in this thread can sort of get you there. For each of several Xantech RS232 commands, unrelated to the 232 commands for the devices you have, you teach IR codes to the device. Then when the device receives one of its 232 commands, it spits out the IR code you have taught it. It thus does not convert from the AV gear's 232 to the AV gear's IR, but instead uses ITS OWN 232 commands, to which you randomly assign meaning, to delive the IR commands which you choose for it to deliver.
