- High quality PCB Services pcbway.com/g/01s7lR Welcome back to the channel! In this follow-up video, we address a common concern from my Rigol DHO800 series oscilloscope review - the lack of built-in WiFi. Today, we're diving into a fantastic solution that involves a simple hack using a TP-Link TL-WN725N USB WiFi Adapter.

00:05 Introduction
03:52 Wifi Procedure
05:40 Hot Swap Test
06:40 Brightness Adjust
Credit goes to the knowledgeable community over at the EEVBlog forum for discovering that the Rigol's Android operating system already contains drivers for the Realtek RTL8188 chipset found in the TP-Link adapter. This makes the upgrade essentially a plug-and-play experience!
To perform this upgrade, you'll need the TP-Link TL-WN725N USB WiFi Adapter (look for WN725 ver2 or ver3 with RTL8188 chipset), a USB hub, and a keyboard. The process involves accessing the Android OS settings through keyboard shortcuts, connecting to your preferred WiFi network, and then tweaking a few settings.
Keep in mind that this isn't officially supported by Rigol, so there might be quirks. The GUI won't show WiFi connectivity accurately, and there's a chance it's not hot-swappable - meaning you should have the adapter plugged in when starting the scope. Despite these minor inconveniences, once set up, the scope will automatically connect to WiFi upon every power-up.
After the hack, you gain the convenience of accessing your oscilloscope over the network. I recommend assigning a static IP address through your router settings for consistent access.
Additionally, we tackle another gripe I had in the review - the lack of brightness control in the GUI. With the keyboard shortcuts, specifically Windows + N, you can access the Android global brightness settings, enhancing your viewing experience on the glossy screen.
This hack transforms the Rigol DHO800 series into a more versatile and connected tool. It's an excellent compromise, especially considering the affordable cost of the TP-Link adapter.

Ah ha! Fixed! Thanks @voltlog!
Thanks Buddy, it works
Thanks 😊
WiFi is also a safety feature - even in case of a catastrophic failure the rest of the network is isolated/insulated.
All ethernet connections are galvanically isolated, since this is part of the ethernet specification.
Or in simple words, grounds are not connected.
If all manufacturers follow the specifications - not all do and from personal experience alone I'm not going to assume otherwise.
@@jensgoerke3819 As long as one side of the cable complies to the standard it's already fine.
I have no reason to believe that Rigol wouldn't comply. They are too big of a company to ignore these things.
If it would be a no name Chinese company, maybe. But you would have much bigger issues besides a scope at that point.
They didn't want to pay for the RFI certification would be my understanding, it's all about keeping costs down.
I've had 2 WiFi cards from a reputable manufacturer with the MAC address FF:FF:FF:FF:FF:FF - if they can screw up such basic things, they can screw up everywhere.
There is still the option to use an ethernet to wifi adapter, bridge or mini router. Does the same thing, is just not as small
This would be a last resort for those scope models that can't support a usb wifi dongle.
That's neat it runs a hacked up version of android, just like what they do with car head units as it's easier to develop on. I wonder if we can hack the usb module internally or use usb/ip??
I don't see why you'd care about usb/ip, once its on the network then you can access it from any PC over http or adb.
I can’t seem to get the usb hub to work. I can use the keyboard no problem but when I plug in the hub nothing works. Any suggestions
Have you plugged in the hub and keyboard, before powering on the scope?
@@voltlog yes with same results
@@markgreco1962 In that case you need to try with a different usb hub.
@@voltlog I have tried three different hubs. I’m going to ask my friends that may have older computers to loan me one.
@@markgreco1962I see same problem with USB 3.0 hub. But keyboard starts to work with USB 2.0 hub.
Shame it is android...
doesn't matter to the user.. still works and feels the same.
