| Should I resurrect the ADAT interface project?[ 9 votes ] |
| 1. |
Yes, I want a 1U rack mount ADAT interface. |
 9 / 100% |
| 2. |
No, I prefer the MEC format. |
0 / 0% |
| 3. |
No, I don't use ADAT. |
0 / 0% |
When the PARIS newsgroup disappeared, I thought the PARIS community had finally given up, so I dropped my plans for anything more than one-off projects for myself.
Are there enough of us still around to make it worth while to resurrect these projects?
The ADAT interface is a 1U rack mount box with a connection for the EDS card and two ADAT optical interfaces.

Wowsers, time flies, sorry for no updates. My youngest kid just went off to college, so now that we're empty-nesters, hopefully I'll have time to get back to work on some of these projects.
After several emails back and forth with Wavefront, they just stopped responding to my questions. Weird. Maybe they only wanted to talk to me if I was going to order 100,000 chips...
So, if anyone is interested in FPGA stuff, chapter 7 of Advanced FPGA Design by Steve Kilts is about I2S and SPDIF, so I'm hoping that will get me closer to my own ADAT implementation...
EDIT: FWIW, I'm working with the Zedboard and Avnet LX9 at the moment, and I have a MicroZed with IO Carrier on order. I'm hoping to interface with my PARIS system through the PMOD connectors...
Regards,
Doug

The TosLink connectors are used in different industries, so I would think that the chip or parts you are looking for are available at some distributers somewhere. I'd try to contact the company that makes the parts and find out who their distributer/dealers are. Also google the part numbers etc. It's got to be out there somewhere for replacement and repairs.

The company that made the originals is Wavefront Semiconductor, used to be Alesis Semiconductor. The chips are officially "End of Life". They were supposed to be available up until November of last year, but I had no luck getting them directly from Wavefront or anyone else for that matter. The closest I had gotten was Profusion over in the UK, but I never heard back from my email inquiry to them.
Of course, I just checked ebay again and now there are at least five vendors who claim to have them! There's hope!

Do you think it would be possible to retrofit the C-16 with motorized faders, and have a separate system with MIDI/USB ports? In other words, don't change the C-16, add to it. Have the C-16 work the way it does with the ethernet, and have a separate system for the moving faders with a USB cable connected to the computer to handle the moving fader stuff. The C-16 might have to sit a little higher with a bolt on box/frame for the additional room needed to fit any additional hardware. It might be easier than trying to build a whole new control surface??? You wouldn't have to really get into board level stuff, you would replace the faders in the C-16 and add the MIDI/USB box/ports. What do you think?

Well, I'm not quite sure I'm following you, but I think the hardest part would be to make a separate interface to the motorized faders. In PARIS, it appears that there's a feedback loop where the software reads the fader and then sends the commands to light the up or down arrows. Those signals would have to be intercepted and used to control the motors. At some point it really does get simpler to just reinvent the whole thing...
