JP1 Remotes

//edit: Serious brain fade. /DTR is not used, and /RTS is active low//

For RMIR to deal with the remote, /RTS needs to be active LOW. This is normally programmed into the FTDI chip, but it is not the factory default. There is a program avilable which allows the end user to change signal polarities. Can also be done by adding a simple circuit tp invert that signal. BTW ...

What Graham said:
Using e.g., FT231XS chiip, with no remote connected, the message is "No remotes found!"
You will also get that same message, with a remote attached, if RMIR cannot find a valid COM port with a remote attached. Either no COM port has been assigned, or RMIR has been configured to try ...

Is it genuine FTDI? Some clones don't work.
Are you using Windows? If so, run 'devmgmt.msc' and check whether there is a Port (COM&LPT) which is identified as belonging to the interface.
Then in RMIR, go to Remote|Interface|JP1x Serial, see whether it has been properly assigned -- e.g., if not ...

I wish that were true -- I read what I see. THe Terk remote produced ICT captures that indicate subdevice is 'undetermined.' Building an rmdu from the hex function codes with Remote Master produced an rmir for the RCRP05B that the TERK tuner would not accept. Leaving the subdevice blank in rmdu did ...

IRScope graph from RCRP05B, I learned 'Power' keypress from original remote, then captured the learned code, graph preamble was 0-0-F-F (hex) when the subdevice was blank.
From the original remote, Power preamble in graph was 0-0-0-0, subdevice also was blank but IRP was undetermined.
Tuner would ...

Addendum:
Code uploaded to RCRP05B, with extender v1.02. For whatever reason, the only way to make it work was to use subdevice 255, which then got inverted to 0-0-0-0 in the preamble.

In this case, IRScope showed that the original remote was sending 0-0-0-0 , leaving the subdevice field blank for my UEI remote produced 0-0-F-F, and the tuner would not accept it. Changing the subdevice to 255 gave me a blank field for UEI AND 0-0-0-0 AND the tuner accepted that. As I said, took a ...

You may note a few pecularities in the assignments for my setup: RCRP05B, Samsung LN37A. On this setup, I have to first power on the TERK before the tv can select the HDMI input mode ...

I think this is what you are looking for

I have several of these remotes, and found them fairly easy to modify.

I never noticed anything unusual at sourceforge, just clicked and waited. Latest version of Firefox does not pop open the download window so you have to watch the menubar at the top...

I am 'experimenting' with linux, the Mint 64 bit version. Got most of my apps installed, then thought about ...

If the LED is not producing anything for the cell phone camera, it is probably not functioning. You could piggyback an LED from a known good source and see whether that works with the cell phone. Use a little bit of extra wire (thin stuff) to get it outside the case and put the case back together ...

Before trying to track down a schematic...

Very likely you have fried the IR LED -- I did that, years ago. There are some posts on this forum concerning that episode.

Since you know how to open the case, use a loupe or magnifying glass to examine the LED anode/cathode inside. BE careful with the ...

Using interruptible pause with RS15-100 and RCRP05B -- the timing roughly works out to what RMIR displays. Working OK.

Also using the 'macro delay' option as my new 'smart' TV has some functions that are just miserably slow, remotes need to be throttled to not deliver IR pulses too fast. Other ...

Some years ago I got an 'Onair HDTV Creator' which outputs HDTV via USB. Ran at first with a laptop (XP) and finally got a fanless Mini-ITX PC which runs the AutumnWave program to record and / or pass through the OTA signal to your TV. Low power usage and multiple inputs can piggyback older ...
