Measured 40mV DC and 4 V AC between the two GND's.
After connecting them with a wire, nothing changed.
I have a separate PS for WaveIO, teleporter and OttoII with a Belleson 2,5A superreg. Works perfectly.
btw: Do I have to change something, like dipswitch settings on BIII?

Not much I can tell you sitting here. :)
You could try changing DPLL bandwidth etc, but my guess is its something more fundamental.

What do you mean by fundamental? Wiring error? DSD format not suitable for BIII? Would it be helpful to take some pics with scope settings of waveforms with OttoII and teleporters in use? Yesterday evening I measured the bit clock arriving at the Sidecar. T=4.10exp-6 s, that means frequency must be around 2,5MHz and if I understand well, clock for DSD must be 64.fs or 2,81MHz. So thats at least one thing being ok. About the data signals: I can not tell you if they are ok; my scope is not able to sync correctly to those signals, but from what I see they look ok. Can't tell it for sure though. btw: Many thanks for trying helping me out. It is much appreciated. I know it is very difficult to do a correct diagnosis not knowing and seeing what is going on  Edited by user Saturday, February 2, 2013 2:47:18 PM(UTC)

If you can manage it you might try taking everything out of the equation but the source and the DAC.
Then you will have a better idea if the source is good.
Also if you have a dual probe scope you could compare the SE signals at the transmitter teleporter and the receiver teleporter.
Very glad to help. No worries.

I'll try to do some elimination and send you the scope pics if I can take them. The scope is an old analog model, but ok for low frequency work and yes, it is a dual probe model. So I hope it will work.
Let you know soon.
Kind regards,
Henri

Hi Russ, I Soldered a cat5 cable to transport DSD signals directly to sidecar. Not my best solderjob ever, but IT WORKS!!!!! Music is so much better than when playing SACD with unmodded player. Rock-solid lock on signal, no interruptions between songs, Only hissing sound when ejecting SACD, but I can live with that. Conclusion: Something is wrong in the DSD -->Teleporter---> teleporter -->DSD --> OttoII chain. As soon I have the time, I send you pictures of signals before and after the teleporters. Many thanks Henri Edited by user Monday, February 4, 2013 12:47:06 PM(UTC)

Next step is to only add the teleporters. Direct to the DAC.

Hi Russ, connected the output of the teleporter directly to the Sidecar. The DAC seems to lock on the signal, but no sound. I took some pictures of the DSD signals. They are all 1V/div and 0,2µs/div These signals taken directly out of the SACD player (before entering the first teleporter) Edited by user Wednesday, February 6, 2013 12:05:05 AM(UTC)

Perhaps it is your wiring to the jack? Edited by user Wednesday, February 6, 2013 12:09:22 AM(UTC)

Then I took pics at the sidecar: I do not think wiring is wrong. Edited by user Wednesday, February 6, 2013 12:13:37 AM(UTC)

Data look completely screwy. :)
My bet is the custom wiring to the jack.

Put the supplied jack on the teleporter boards (you don't have to use it later) and try connecting the cable that way.

Russ, I will check all the wiring etc. tomorrow and solder the RJ45 connectors in place. It's 1h15 over here in Belgium and I really must go to bed. Maybe a fresh look tomorrow will reveal what is wrong? many thanks, Henri Edited by user Wednesday, February 6, 2013 12:20:06 AM(UTC)

Often that is the case. Fret not. I believe it can be sorted. :)

One thing I am just now noticing is that the data out level seem pretty low coming from the player - like around 1.5V that seems very much on the low side. I am not sure it is high enough for the LV/TTL inputs of the teleporter... Now this may not be the problem at all, just an observation. Seems very strange for it to be so low when the bit clock appears to be a normal TTL signal. Edited by user Wednesday, February 6, 2013 12:28:19 AM(UTC)

I just checked signal levels coming out of SACD player, and they are all 3,5Vpp. Sensitivity of my scope must have been set not equally for all screenshots. So the teleporter gets TTL signals in. Sorry for the mistake. Today I try to mount the supplied Jacks on the teleporter board.
I let you know what happens.

Hi Russ,
Mounted the TPA supplied Jacks on the teleporters boards and output directly to the BIII. Works like a charm!!
Seems to me a wiring error or bad contact was the cause of all these troubles.
I'm curious if the increased instability of the I2S signals coming from WaveIO (my main source of music) is also gone.
Let you know soon.
Thanks again for the advice.

Hi Russ, Just finished modding of the SACD-player. Plays perfectly! Now start modding BIII. At first I make plans and ordered OttoII to switch between I2S OR DSD. Then I read the blog HIFIDUINO by GLT. Do you think I can connect both DSD source and I2S source to the Sidecar?. BIII will recognize the format and play it as long both formats are not simultaneously present and that is fairly simple to do, I think. That way I do not need the Otto switch board.What do you think of it? henri47 attached the following image(s): Schermafbeelding 2013-02-06 om 14.51.31.png (204kb) downloaded 19 time(s).You cannot view/download attachments.
