The failing was mine because I trusted the triangle, and everybody else has been smart enough to ignore it.

The photograph at http://www.hifi-remote.com/forums/viewtopic.php?t=16360 shows the triangle which typically identifies Pin 1 at top left.

My apologies for not thinking this through thoroughly before posting.

Your link is to this entire thread, and not to an individual post. So I can't tell which photograph you have in mind. There's a small rectangular icon (maybe it represents a piece of paper) in the heading for each post just to the left of "Posted:". Right click the icon and select "Copy link address".
For example, the third post in this thread is http://www.hifi-remote.com/forums/viewtopic.php?p=121028#121028

Note that this link has the format ?p=xxxxxx#xxxxxx. Compare this to the link you provided which has format ?t=xxxxxx

Thanks for your guidance.

The link is http://www.hifi-remote.com/forums/viewtopic.php?p=120954#120954

The photograph I refer to is under "The following pic shows how the pins are numbered for the 6-pin connector in the remote itself:" and shows the rear of a cabled 6-pin connector.

Thanks for the explicit call out of the photograph you have in mind. However, IMO the photograph and accompanying figure do not support your assertions, so I'll bow out here, just noting that the head post of this thread does correctly describe the numbering of the pins.

This video shows you how to connect the cable:

The arrow at upper left on a 6-pin connector identifies pin 1, and I connected the cables as per the post:

1 - (empty):VDD
2 - Yellow:RTS
3 - Black:GND
4 - Green:TXD
5 - (empty)
6 - White:RXD

RMIR told me 'Remote not found'.

The photograph showed 2 and 6 were reversed from the text, so I connected the cables as per:

1 - (empty):VDD
2 - White:RXD
3 - Black:GND
4 - Green:TXD
5 - (empty)
6 - Yellow:RTS

RMIR downloaded without issues.

I watched https://www.youtube.com/watch?v=cLYzsh-usTo, and the narrator identifies Pin 1 as upper right, which is actually Pin 3. This would explain why the 2/6 transposition worked for her.

The photograph pin numbering is 1-3-5 on the upper, and 2-4-6 on the lower. If you can give me an email address I can forward you a PNG which identifies each pin and could be a suitable replacement in the post.

I'm failing to see what you're seeing in the photos.

"I'm failing to see what you're seeing in the photos"

The triangle on a connector identifies Pin 1, in this case it does not.

Ah, I see. I'm curious why you decided to trust that triangle rather than anything actually written in the post or described in pictures that we created?

If you look at the pic below, there are 2 different diagrams showing quite clearly that pin 1 is on the other side.



Btw, you can't expect BBCode to display correctly if you check the "Diable BBCode in this post" box. I have to keep editing your posts to uncheck it so that quotes and images display properly.

A few years of building computer cables e.g.



I did not realize I needed to interpret where Pin 1 was by examining the diagrams until 3FG responded.

Thanks for the BBCode clue, had no idea why my posts were 'plain'. Disable was the default and did not know it affected the representation.
