USB fiber connection bug between RS130 and RD160

Hi @PatriceP @ROSEHAN

Here’s what I do to keep the USB fiber connection between my RS130 and RD160 maintained without erroneously linking to USB after system turning on from standby.

Turning ON (from standby)

  1. Turn on RD160 first.
  2. Until RD160 completely turned on, I then turn on RS130.

Turning OFF (to standby)

  1. Turn off RD160 first.
  2. Until RD160 completely turned off, I then turn off the RS130.

In the past week, via above ON/OFF sequences, the USB fiber connection between my RS130 and RD160 are properly linked to each other without error after system turning on from standby.

Hope above helps

Hi TomT,
Do you turn off the RS130 completely or just put it on standby?

#17

I meant standby, of course.

Sad to report that the USB misconnection bug appears again after running properly for a couple of weeks.
Everything remains the same. The bug just appeared again yesterday.
Not a big issue but a bug is a bug.
Hope that can be solved in next update.

I’m using your method and so far it seems to be working.

Have you tried disconnecting the SFP on the RS130 side and reconnecting it? For me it worked after a few reboots without errors…

#20

Good and let’s keep on testing.

#21

Hi @TomT , can you tell me more about the sound of the RD 160? No one talks about a device that costs more than 6000 euros

#22

@VIK

5,299 €

This is a rather brief test, but I confirm that this DAC is incredible, endless details, without the inconveniences of hearing tiredness. The sound is truly analog.
Contrary to what is written in the test, you can completely turn off the screen (maybe the tester didn’t have the right firmware version).
The RS130 - RD160 combo is certainly expensive, but damn, it sounds good… No regrets for the hardware, hoping that the software team will start by stabilizing the software before adding other functions that we don’t really care about…

Advantages
Absolutely natural, thrilling and dynamic sound
Wide selection of digital connections
Outstanding workmanship

Disadvantages
Clear cracking noise when switched on
Display cannot be switched off completely

Do you also hear the cracking noise when switched on?

#25

I have no cracking, neither when turning on nor when turning off.
You can choose to turn off the screen completely from the menu, in the screen save submenu

I use a ground box for all my devices, maybe that’s why I don’t have any cracking…

My unit has no cracking noise when switch on or off. I have no ground box.

So @VIK
Many other friends have answered your question about the sound of the RD160.

Hi @Bonte, I don’t have a ground box and I don’t hear the cracking noise (except the clicking sound of the relay of the device) during ON and OFF. My screen can turn off completely as well when standing by.

Hello boys,

thanks for your answers. :+1:t2:

Once again you can see what to think of such reviews or tests. It might be a little reading on the side, but as always it’s better to try it yourself and with your system.

Have a good start to the new year everyone

Firmware bug detected in the RD-160 or RS-130 or both !

After many tests I confirm that the FTP connection between the RD-160 and the RS130 via FTP is unstable.

Firmware version:
RD-160 CPU: v1.17, MCU: v1.01
RS-130 version v5.7

I am using two FTP+ from H!.Fiber, type AXS85-192-M3 10GBase-SR SFP+ 850nm 300 meters.
The fiber is an Elfcam OS2-LC-LC-D1 simplex, but I can indifferently use also a 10GTex OS2 LC-LC.duplex

The first connection takes more or less 4 minutes (not 1 as the firmware states) but after the link is synchronised it remain stable for the full. session.

The problem arise when the systems are set in stand-by.
By following these sequences, most of the times the link continue to work:

A) Turning OFF
A1) RD-160 OFF first
A2) RS 130 OFF when the RD-160 OFF cycle is completely done

B) Turning ON
B1) RD-160 ON first
B2) RS-130 ON when the RD-160 ON cycle is complete.

Even so, randomly the link at power ON (from stand-by) fails:

This is clearly a firmware bug in one of the two systems or both.

Hoping that ROSE will spend some time to solve this annoying defect, unacceptable on devices so expensive.

Now I can compare four links between RD-160 and RS-130

Link1: the I2C in A mode
Link 2: the standard USB connections
Link 3: the H!Fiber DAC SFP+ 10GB/s 1 m Twinax-Copper
Link 4: the H!Fiber AXS85-192-M3 10Gbase-SR SFP+ 850nm 1m

After hours of listening I have no doubts: the best link is the number 4, optical fiber link

Very soon I will test the fiber link by means of two Finisar FTLX1475BTL

Don’t forget to order a Corning fiber !

#33

Or Phoenix Contact fiber optic. Is fiberglass (see attached).Untitled

#34

Corning are fiber glass as well…
