So my cable works perfectly. I've included the old thread and the avid page. Both say hook pins 2 to 8 and 3 to 7. Perhaps the confusion is that you have to go both ways. For example 2 to 8 and 8 to 2, 3 to 7 and 7 to 3. The addition in the Avid doc of pins 4 and 6 as commons seems strange. My cable works going directly into the deck from the keyspan out of the avid. I can play and stop a timeline from a dvw-500. If I go through our internal RS422 patchbay and use my crossover cable it still works. Our internal RS422 cabling only has 5 active pins 2,3,4,7&8. So clearly pin 6 isn't necessary and I'm doubtful pin 4 is needed but no harm in following the exact spec. I did try to reverse the audio patch cables that are part of our RS422 patch panel but that didn't work for me. I'm guessing the patchbay FF had was wired differently than ours so it facilitate the proper cross over connections while ours doesn't by swapping the patch cords. There is a lot of traps and you have to delete any active channels in the deck configuration so there is no conflict with the serial port setting which has to be active for remote play and capture work. The reverse is true to. Once done with remote play you have to select none in the serial port setting to be able to configure a deck.
As for the pinouts in the original thread I posted they are working for me. I'm going to suggest there was other configuration issues that weren't addressed when testing the home made cable. While it can be argued it takes more time to wire it up than order it but really with the avid specs it took .5 hours to wire. Learning how to properly configure the Avid took most of the time and that would be the same with the store bought cable. I had no need to plug into the deck RS422 out connection the regular serial control in connector worked just fine. I was working on macs so I didn't have to address any of the driver issues PC's may have. Perhaps someone who said the pin outs were wrong owes me an OKI Dog. ;-) Just kidding the Palm seems more appropriate.

If I read the following chart correctly then to build the necessary RS-422 cross over I hook pin 3 to pin7(TX+ to RC+) and pin 2 to pin 8(RC- to TX-) Does this seem right?
DB-9 RS422 Pinouts
The TX and RC signals as well as the pin 1 ground follow the SMPTE standard. Antona uses the added pins 5 and 9 for application of external power to our adapters. The pinouts below are referenced as coming from our series ANC-6000 adapter when it is configured for master operation.
DB9 FUNCTION IDENTIFICATION
1 GROUND ground for RS-422 and/or external power
2 RC- RS-422 minus side input
3 TX+ RS-422 plus side output
4 -not used-
5 GROUND ground for RS-422 and/or external power
6 -not used-
7 RC+ RS-422 plus side input
8 TX- RS-422 minus side output
9 +V Optional +5V to +12V DC @ 100ma
The pinouts below are referenced as coming from our series ANC-6000 adapter when it is configured for slave operation.

3 RC+ RS-422 plus side input
