Useful 15 pin connector for Flex accessory port

K8AC

When I came up empty searching my junk box for a 15 pin connector for the accessory socket on my 6500, I ran across this connector online.  
It has **** compression terminals for all 15 pins and the green terminal section and plug can be easily removed from the black body for attachment of wires.  The shell's cable entry will handle multiple shielded cables if necessary and it has a cable clamp to secure the cables to the shell.  Available on Amazon or eBay at reasonable prices.  Search for "DB15 breakout terminal".  This sure beats struggling to read pin numbers and soldering to those close-spaced pins on the rear of the usual connector.

Also, a breakout box like this would be a very handy way to cobble up a custom band-data cable for the Power Genius XL.  One end of a wire could be whatever you need to connect to a transceiver (or other band-data source), the other end could terminate in one of these, configured to supply the band-data signals to the correct pins.  The pin-out data is in the PGXL documentation.

Yes, the link I posted just above would be for the correct format connector on amazon.

Partially true.  a RS-232 connector that size would have only 9 pins in two rows.  I posted the best photo I could find in a short period of time - didn't think there'd be so many keen-eyed readers.  Anyway, it's clear that these connectors are made in every possible combination of pins/rows that fit in that size connector.  Think I'll pick up a 9 pin for future needs.

I think I found the answer in the hardware reference manual.

Does anyone know what pins are used for audio line in from a TRS 1/4 inch plug? I see pin 1 says line in, but what is ground and do I just use tip and sleeve without ring. I have the accessory plug above and a cable I can cut one end off of. I'll be connecting the line in to a line out on an audio interface (line out) so I can use one mic with my PC or radio. I am searching through the community, but can't find the exact info on which pins. I guess I can do trial and error until I get it right. There's not a lot of detail in the details.

By the way, I am using a Flex 6400M and not a 6600.

My only issue with this connection is where the audio is derived from. I think the audio that this port utilzes should be clean, no processing like the DIGU or DIGL audio. It should not be processed at all. This being for both the input and output. I utilize an RM2 M110A modem successfully with this port, however I can see how my equalizer affects the output of the transmitted signal when this mode truely calls for a completely clean non modified audio signal to truly get proper speed and quality of transmitted and received signal. The other issue is the output of the audio is also controlled by the same levels that are used for me to hear the radio which removes the signal audio to the modem removing the ability for it to receive anything. Just not a good idea in my opinion, it should have its own settings and be unedited clean audio.
