How is the toslink connected?

Hi glt,

He posted a picture which also shows how he connected it. Post 1134

Thanks again for your help I have installed the relays that I had sitting around doing nothing & now everything works. I can switch between the the sources (must buy more sources or build some sources ) and I am back to the SPDIF Coaxial which appears to be working fine, unlike the toslink.

All that's left to implement is the screen.

I am a bit disappointed with the TP people they had 14 days to offer some advice & didn't even though I asked them directly, then within 2hrs of me suggesting the number of dropouts with the BIII was a bit flaky, I had a response from Russ defending the BIII!
I don't use Arduino so why would you want advice from me on that? I knew the arduino community would pitch in.

I figured it was best to allow users who use it to answer your questions. The rest of the details you needed you had in the integration guide.

Input 1 No reading & No reading
Input 2 To Ground & No Reading
Input 3 No Reading & To Ground
Input 4 To Ground & To Ground

I haven't had a chance to test the BIII inputs
You have to make sure pin 6 and 8 are pulled up. (say with 10K) That is normally done by the controller. With a stock B3 this is done by the on-board controller. You your case you need to be sure *your* controller does the same thing, or do it externally.

on the other avcc reg, the D1 does not light up but both output measure about 3.42

Do you think I'm good to power the board?
What does D1 indicate?
D1 definitely should light up. Have you tried testing the AVCC module in isolation?

As for the TOSLINK module - you may need to check that you are getting a good signal out of it. If you have the voltage divider working correctly the output should be equivalent to the consumer level signals.

Also make sure that since you are using the voltage divider you terminate the SPDIF-4 input you are using for that signal at 75R just like the other consumer level inputs.

Thanks. The spdif input for the sabre32 should be rock solid. One idea is to directly connect the toslink output to the input of the BIII and avoid all the "unnecessary" level conversion. One way to do this is to tap the ribbon cable. Another way is to solder to the pins at the bottom of the pin header

I would suggest using grid connectors to simply connect the pins the way you want them.

I noticed your tinkerkit MOSFET modules. What are you switching with these modules?
I am switching on my Linkwitz ASP crossovers, that I use for my own speakers, that was a learning experience

There is also a Tinkerkit relay module you cannot see.

I am also switching my 2 amps & the BIII, all sequenced to avoid those awful noises, although I'll have to say the ASP's & BIII dont make really bad noises when switched off before amps, the MiniDSP I was using for the crossover made TERRIBLE noises come through the speakers if you got out of sequence. I remember one day accidentally switching off the MiniDSP first, the noise scared me SO MUCH, while my finger was still on the switch I switched it twice more, needed a good lay down after that

I imagine I may need help with the volume display as I'm not sure howI am going to make it work without removing the firmware chip.

Thanks again.

I have tested in isolation with 5.25V salas shunt input


I have 2 BIII on the standby for dual mono and both avcc D1's did not light up.

I gave the salas a bit more current and both light up now. I should be good to go with those voltages.

thanks.
