Rossini + Vivaldi Clock Power Link?

Erno, this is for the DAC. The issue concerns the clock.

The Rossini Clock works in a similar way:

Thanks for the clarification. However I am not certain that Baud rate is the only issue that is relevant here and I think that information from dCS when @Phil returns from the holiday period may be needed.

Erno, thats showing how to set the baud rate on the Serial communication software, not the dCS component! :grin:

The manual says:

The Clock’s settings can be changed […]

That is the component, or is it not?

Hi All,

I had a query regarding exactly this last week on [email protected] too…

It is not possible to do power sync between a Rossini DAC / Player and a Vivaldi Clock via RS232.

As Anup has already spotted and commented upon, the Rossini and Vivaldi use a different RS232 Baud Rate so cannot “talk” via RS232 and the Baud Rate used by the Vivaldi and Rossini cannot be changed. The RS232 ports can be used to change operational settings on the units but the Baud Rate used by the units is fixed and cannot be changed.

I hope that helps.

Thanks Phil, now that is clear.

Back in the days, I used to set the baud rate on my modems as desired, so because of that I thought it could be done in this case as well.

If the communication between the two is not possible by just using 1 RS232 cable between them -and if one really wants the two to communicate- then a solution is to use an Arduino with more than one hardware serial port. (Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s intended for anyone making interactive projects.)

Actually, if folks are desperate to get it working, just locate an RS232 Baud Rate Converter. They used to be pretty common, less so these days.

Although rate conversion may solve a significant reason why the two components appear to be incompatible, I wonder if this alone will allow the wanted operation?

It seems that there may be a handshake first between the units and this seems to depend upon recognition of serial numbers. I found that Mosaic would not recognise one of my units with an erroneous number. The second issue is that the numeric string making up the command code may include a device code which serves the purpose of stopping the operation of unrelated devices.

Just to be borne in mind before committing time and money.

As we are discussing pressing one button instead of two I don’t think tnat the continuation of civilisation depends on the answer :wink:.

I can’t guess at what your Mosaic issue might be, and I don’t quite know the exact mechanics by which two linked components initially recognise whether their respective RS232 port is in binary or text mode.

However, the Power-link function with the Rossini/Bartók/Rossini-Clock does not depend on it.

I know this for a fact as I’ve looked at it with an RS232 breakout. There are no serial numbers or other codes exchanged between the units for the Power-link to function. It literally is just simple commands sent by the DAC to the Clock.

:grin: Yes, but typically my curiosity won’t rest until I know how it works.

Or, in this case,doesn’t :smiley:.

I do not have this issue any longer as dCS fixed it by correcting the incorrect serial number. Nothing to do with data mode necessarily as far as I can tell. All components involved were Vivaldi in their default setting as far as this is concerned. Incorrect serial number and Mosaic could not recognise the unit, correct number and it did. Excellent service from them (of course BTW).

Excellent and informative answer, @Anupc.
This leaves us with just the remote control as a solution for a Rossini/Vivaldi Clock stack – both units will sleep/wake from the Universal Remote (if you press power for 2 seconds).
Might have to go back to shopping learning remotes to reduce the clutter of remotes that has been accreting around here…

As the Rossini Clock does not have an IR receiver, using an RS232 straight through cable to put it to sleep from the Rossini DAC seems the right way to go.
Would this be the correct cable to use?

Yup, that’ll work.

Stand up from chair, 2 sec
Walk to rack, average 5 sec
Turn off DAC and Clock, 3 sec
Total 10 sec

Turn off with RS232, 2 sec
A benefit of 8 sec!!

If you just leave them on:

  • In time: 10 sec longer listening
  • A better sound(?)
    Disadvantage: more power consumption

I made my choice much earlier, did you?

If so it doesn’t matter however in the context of this thread which is about Rossini DAC with Vivaldi clock.

The way Mosaic discovers dCS components is quite interesting when looked at closely via Wireshark (as I outlined in a previous post). I don’t recall seeing any kind of serial number validation as such, my guess is that the incorrect serial number might have been a symptom of something else being off. In any case, glad it was fixed swiftly. :slight_smile:

There are quite a few new Universal Remotes on the market lately, many via Kickstarter though (so tread carefully). There are also some recommendations on dcs.community for Universal remotes, so a search might be handy as well. Good luck! :+1:t3:

I’ve enjoyed learning new things through this thread, but… isn’t this a lot of work to avoid clicking the on/off button, or just leaving the unit on all the time?

According to the manual, the Vivaldi clock “typically” only draws 10W, so if you leave it on all year, that is 87 kWh. A typical household uses (US) ~8,500 kWh, (EU) ~6,000 kWh… So, we’re talking between 1-1.5% of annual household energy usage.

Just sayin’ …
