[QUOTE="arsenal333, post: 694817, member: 28103"] Another night of trial and error - results..... Using the RS232 Hex Com tool, I've been able to successfully send the off/on, HDMI1, and TV Tuner commands to my Samsung LED TV. In the RS232 Hex Com tool I set the command to be sent as Hex rather than Ascii The following strings have worked. TV Off \x08\x22\x00\x00\x00\x01\xd5 or 082200000001d5 TV On \x08\x22\x00\x00\x00\x02\xd6 or 082200000002d6 HDMI1 \x08\x22\x0a\x00\x05\x00\xc7 or 08220a000500c7 TV Tuner \x08\x22\x0a\x00\x00\x00\xcc or 08220a000000cc It seems that the RS232 Hex Com tool can easily interpret and send either string. I noticed in the 'echo' that RS232 Hex Com tool will strip out the x\ characters and send '08220a000000cc'. So having this working from RS232 Hex Com tool it was time to move onto IRSS, and setting up Marco's to send the serial commands. I've used IRSS macro's previously to control my Marantz SR7002 through serial interface - works very well :D anyway - I setup the Macro for serial send, and tried 082200000001d5 and \x08\x22\x00\x00\x00\x01\xd5 both of these attempts didn't work. So I tried \x082200000001d5 fail - help suggests the use of \x for Hex \x08\x22\x00\x00\x00\x01\xd5 fail - help suggests the use of \x for Hex 082200000001d5\r fail - \r return character (I have to do this on the Marantz Macro's \x082200000001d5\r fail - \r \x08\x22\x00\x00\x00\x01\xd5\r fail - \r Don't suppose someone could suggest the correct syntax for entry :S :thx: [/QUOTE]
