Hi,

I'am new to programming remotes but succeeded wonder well in the IR part of the Pronto TSU 9400.(I'am loving the simplcity and the complexity of control that are possible with it) All devices except an old Yamada 6600 DVD player are working fine. I'am using PEP2.

The challenge i'am currently working on is how to control my Sharp LC-42XL2E via the RS232 connection. This because my Telly is on a flexible arm and if i use the IR sensor it will be in sight. The RS232 connector is at the back and can be connect partialy hidden.

In the manual is mentioned that a cross cable is needed. This i bought and connected to the RFX9600 RS232 port1. And it discribes thecommand format of teh ACII codes.

Comand 4 digits parameter 4 digits and return code (It says the return code is 0DH) Serveral codes are given for instance the power OFF is POWR0   (This includes at then end three spaces. Or input selection B this is INP10   (again three spaces) for ext1.
I read through the forum but could not find a solution how to get the RS232 codes put in correctly.

I tried several ways of putting in the RS232 codes (ASCII mode) into the device database.
Versions i used was:
POWR0   0DH
POWR0   ,0DH
'POWR0   ',0DH
'POWR0   ',$DH

Is tried the IR code i have from the Sharp which is working fine put into the HEX mode of the RS232.
0000 006D 0000 0020 000A 0046 000A 001E 000A 001E 000A 001E 000A 0046 000A 0046 000A 0046 000A 001E 000A 0046 000A 001E 000A 001E 000A 0046 000A 001E 000A 0046 000A 001E 000A 0679 000A 0046 000A 001E 000A 001E 000A 001E 000A 0046 000A 001E 000A 001E 000A 0046 000A 001E 000A 0046 000A 0046 000A 001E 000A 0046 000A 001E 000A 0046 000A 0679

But also no succes.

The RFX9600 seems to work fine because it light up when is send the code on the first RS channel.

Should i use the ASCII coding or HEX coding. An what are the syntaxes used in both. And if Hex is use how do i get from ASCII to HEX?

I'am probably barking up a wrong tree with the coding but hopfully some one can help me barking up the correct one.

Does it require a carriage return after each command? " /r "

Return code of 0DH means hex 0D (i.e. 13 decimal). So you cannot enter ODH as ascii, or the remote will send characters '0', 'D' and 'H'.

Replace "0DH" in your example above with either :

\x0D

or

\r

It does but in the manual this was indicated as 0DH. I will try the \r.

IR code data (ProntoHex) as RS232 input does NOT typically work.

Barry Gordon, on his site has a data communications document that might help you understand more about said topic.  www.the-gordons.net.

I've tried different options and the one that seems to work is

POWR0 \x0D

thanks for your quick respons and help. Going to try the other codes to see if they all work the same way.
