Know it's a 6 pin RJ-11. Anyone know if it's a straight through or does it have weird pin-outs?
Looking to slave a 722 to a 744 for a BLR acoustic gig. Don't feel like schlepping the 24 track out for a 6 channel gig.

Straight through.

Thanks for the reply...
SD site says NOT to use phone cables - looks like a plain old flat 6 conductor cable.

What SD says in the 722 manual (v2.65 page 21) is don't connect the 7xx boxes to phone lines.
The C. Link jack is a proprietary RS-232 port. Under no circumstances should analog or digital telephone
lines be connected to either jack. Serious damage may result.
So you can use a phone cable to connect two 7xx boxes together, just don't connect a 7xx to the telephone system. Perhaps SD should have use a different connector. Or maybe they were trying to drum up repair business (that's a little joke).

a standard phone cord is going to be 2-6 pins and the pinout is not straight through it is going to be [1,2,3,4,5,6] - [6,5,4,3,2,1]
Anything cat3 or better should work or if you have some ribbon cable.
If anyone needs one of these made up i can whip one up and send it for just the price of shipping

If you measure the cable that came with your 722 you will see that it is a 6 pin phone cord connected [1,2,3,4,5,6] - [6,5,4,3,2,1]. That is what I meant by "straight through" but I was using that description incorrectly. My mistake was to measure the cable as it lay straight across the bench not remembering the connectors would then be reversed relative to each other.

Had one made for me - $1.50. RJ-11 6 pin - duped from photo on SD website.
Thanks guys..

FWIW - I have successfully used standard RS phone connectors to C-Link my 722's. And it worked just fine.

Straight through.
INCORRECT. The 7XX boxes use a "crossed" cable and NOT the straight through for C-Link.
From SD:
All 6 conductors must be wired. Many standard telephone cables only have pins 2, 3, 4, and 5 wired.

Yes, I have already acknowledged my mistake in calling a standard 6 conductor telephone cable "straight through". My point is that a standard 6 conductor telephone cable will work just fine.
