pico 5204 not recognized using Silex SX-DS-4000U2 extender

Post by hans-hbn »

Hello All,

I try to use my PICO 5204 scope attached to a Silex SX-DS-4000U2 extender over my local network.
The extender is wired to the router via a switch, the laptop I am using is connected via WIFI.
Using windows vista at the laptop.

Using the SX virtual link program I see the PICO 5204 shown up attached (icon: camera) but after I make the connection using SX virtual link, the picoscope software (version 6) does not recognize a connected device.

Any hints how to solve this?
Regards,
Hans

You may have to reconnect the scope in the extender's control panel window.
This should only happen first time the scope is connected with the PicoScope software. (We have tested a similar device)
(PicoScope software disconnects the scope to load the scope's firmware)

Have you tried connecting your pc directly to the extender via Ethernet?

I have the Silex DS-600.

I am trying to connect it and I am having similar trouble to the issue above.

I see the device while connected through the server. It first pops up as WestBridge. When I run the DS-600 software and connect the USB device, the picoscope software does not seem to see the device. I am unsure if it is because of the name of the device in the USB to Ethernet server. I tried renaming it to PicoScope 6000 Series PC Oscilloscope in the server software. This did not work. It seems that the driver is looking for something specific. Can I alter this, or alter the USB to Ethernet so that I can match what the drive is expecting to see?

I have noticed that the location in the device function summary is different when plugged in through the DS-600 server.

It looks like the Picoscope drivers are looking only at a specific port.

There is a two stage process with our devices when connected to USB.

When first plugged in they enumerate as a simple PicoScope device, they are not a fully function scope at this stage. When the software opens the scope, the driver will load the runtime code into the device. At this point the scope will perform a restart, and will then re enumerate on the USB bus again but as a different device. It is this dual operation that can cause these extenders some difficulty, and you need to identify the device in the extender software a second time.

If you open Device Manager, and then open the software, you can see this double operation in progress.

I don't have access to a Silex device, or it's software, so can't say exactly what settings you will need to change.

I have solved all the issues. I now have a high speed wireless set up working.

It streams the data no problem.

I know there are several people out there looking to solve this issue.

So for the record, a DS-600 will close your USB3 pipe down to 800MBits per second, but you can still get some decent sampling rates streamed wirelessly.

Disconnects can cause troubles because of this hand shaking process you mentioned. A fast reconnect process is required if you are to lose connection. I intend to fight this with higher gain antennas on the router. Eventually I will want to drop the DS-600 and simply have everything on the router.

I will try to achieve this at greater speeds later on. I got this set up for proof of concept for now.

Thanks for your help.
