Greetings,

I am attempting to make a TDIF splitter (eight in, sent to three eight outs), and for the life of me, I can't find any information on this interface, other than the pinouts.

Does anyone know if its ttl line outputs, cmos outputs (and powered at what voltage?) I don't have an o-scope to reverse engineer it, all I need is the signal voltages peak to peak, and if they cross zero.

Thanks in advance,

Frederic

y'know... months ago I tried to figure that same thing... http://www.tascambbs.com/ubb/Forum1/HTML/000498.html


But you might try the tascam boards..they're pretty smart over there.. http://www.tascambbs.com/cgi-bin/ubbcgi/Ultimate.cgi?action=intro

Warranty be damned, huh? LOL. Yeah, well, I managed to make a cable that just sends the signal from one TMD1000 to two Akai DR8's. Works fine. Electronically, I'm sure it leaves a lot to be desired, but it worked. The cable actually has four heads on it... one to the mixer, three to my hard disk recorders, but when I plug the 3rd recorder in, the signal isn't strong enough, as expected.

I was hoping to build a buffer. Made a patch bay at least using an ordinary 25-pin straight through serial cable cut and soldered to an ADC patch bay, so I can swap units if I want. Not ideal either.

Anyway, gonna have to borrow an o-scope, seems to be the only way. Once I do that I can reverse engineer the voltages and signal thresholds and make a TTL or HC TTL or CMOS interface.

The tascam BBS didn't help me out... though I did call tascam corporate twice, offered to sign documentation indicating I wouldn't make it public domain, etc, but no luck yet.

*sigh*

Thanks though!

Not really... just have an idea on how to attach 8 analogs and 24 tdif channels to two little 16 channel mixers. This is a tide-me-over until the D24 comes out. As much as I like everything I have read, heard or conversed about the D24, I need it now. A splitter solution would allow me to suffer until the late spring when the new units ship.

Hopefully :)
 
do you know how to make a TDIF cable that goes in from one jack and out to a different jack? Like, say, into a mixer from some converters, and out off the same cable to some recorder??

If I understand your question(s) correctly, yes. If I misunderstood, my apologies, lets try again :)

Anyway... I made a TDIF cable that it not electronically the right way to do this, but it connects different devices to different devices in a specific combination I needed. In my case, I have the TDIF output of one TMD1000 going to both hard disk recorders, and the outputs of the two hard disk recorders going to a different TMD1000. I use one for record, one for mixing audio.

I tried with three hard disk recorders, and I think there was to much load on the mixer's TDIF out, which is fair, its not designed to do what I was trying to do, so I need to make a splitter.
 
wowsers. I think I might have to borrow your design... but not until next year.
