Has anyone had any luck using the IR flasher in port on a new Sony TV ? The URC codeset is correct as an emitter or direct IR works fine. There is no documentation from Sony on this. Is this port looking for a stereo mini for a Dinky Link or is it a regular IR in looking for a mono mini ?

It is a stereo jack. I cannot remember off the top of my head if you use tip and ring or tip and shield. It is different from the projector IR jack pinout, that I know. It works fine without setting to "direct ir", at least in C4, and in Elan I did not have to do anything special.

I just sat down on a job and tried every possible combo until it worked on both the TVs and the projectors. I planned to document it for myself at that time, but failed miserably, so the next few, I had to figure it out again....and still did not document it. :P

What I do not like about the projectors is that when you use the IR jack, it disables the IR sensor. You can no longer use the OEM remote. The TVs are not this way thank goodness.

Some research shows at least one model where that jack can be set via the menu for RS232 or IR. I'd like to research further so I'd like to know exactly how the jack on your TV is labeled and what model TV it is.
A good answer is easier with a clear question giving the make and model of everything.

Is this for Sony TVs, Projectors, or both?

I think projectors are mono, tip ground, sleeve signal. Polarity is reversed on the projectors.

Manufacturers are such a PITA. What purpose does it serve to not have them the same across the board?

That has been a Sony IR thing for a very long time. Panja used to have a Sony setting in their control systems what would invert the IR polarity electronically.

Sony's a BIG company. Very likely the enginerring group that develops projectors is not the enginerring group that develops televisions. This variation from product category to category can easily develop if there's not somebody at the top who issues and enforces policies of uniformity.

The projector guys want to have an IR jack. They think about it and decide what they're going to do. They don't call the lowly TV guys and ask them how they do it. First, they might not know them. Second, it might not occur to them that the TV guys have thought of such a sophisticated thing.

These days society as a whole values "doing your own thing" more than uniting and acting as a cohesive whole. I'd be surprised if there were anyone at the top at Sony who encouraged or insisted on unity of design and/or style. I'm reminded of a friar named Brother Lawrence, born in 1614, once said something along the lines of "it is not a mystery how much trouble men get themselves into. The mystery is how little trouble they get into!"
