Hi,
I have followed the instruction to try to connect EZB 4 to PC by USB from the link as below: https://www.ez-robot.com/learn-robotics-serial-usb-connectivity-ezb-smart-robot-controller.html
But It is not works. I guess, I bought the wrong USB adaptor (shown as below) or something wrong in connecting. So, would anyone have any suggestion for the USB? (EZB to USB adaptor, GND to GND, RX to TX, TX to RX)

Thanks in advance!

Hi Rickymahk2013,
The EZ-B v4 is designed to connect to your PC over Wi-Fi, not USB. The USB port on the EZ-B v4 is for firmware updates only.
To connect your EZ-B v4 to your PC, you should follow these steps:
If you're having trouble connecting, make sure your PC's Wi-Fi is turned on and working properly. You might also want to try resetting the EZ-B v4 to its factory settings. You can do this by holding down the reset button on the EZ-B v4 for 10 seconds.
If you're still having trouble, you can find more detailed instructions and troubleshooting tips in the Synthiam support section.
I hope this helps! Let me know if you have any other questions.

Ricky that usb adapter should work great. It may need the rts enabled in the connection control settings. Some usb adapters require that.
as for wiring, the link you provided is the best source for it. My debugging recommendations are
to check the wiring,
verify the baudrate on the ezb matches the connection control
try with rts enabled in connection control
Thank you DJ!
I have try to follow your instruction. But still is not works! Please see the attached picture for your ref.
EZB connect to USB
USB connect to tablet
Though Bluetooth to connect EZB (196.168.1.1.) and set the USB connection to 921600 in "Advanced Setting" and then save and reboot.
In software ARC Pro - Connection - COM/USB connection change the EZB#0 to 921600 and click the "RTS Enable" button to match the EZB setting.
And then refresh the connect button in connection. But no any change!
So, I have no idea what wrong in my procedure. Anyone can help? Thanks for advance.
hi
i'm not sure but i believe you have to switsh the tx and rx on the other side of the cable . i'm wildly gessing .on the camera cable .
Check continuity on all wires to the board. I've had bad jumper wires and weak connectors in the past.
What kind of PC are you trying to connect to? Check the USB port on it in windows device manager.
Maybe something in the PC is keeping it from connecting. I once had trouble connecting some EZB's to a SBC through USB. It was driving me crazy. I finally found I needed to install missing window drivers in the SBC's.
Thank you Normad, I have try it but not works.
Thank you Dave, I have try desktop PC (MSI MEG Aegis Ti5 Gaming Desktop Computer) and Tablet (Surface Pro). But both is not works. I'm not sure, is it missing the driver. If yes, do you know where can download the driver?
Okay there’s two things that is stopping it from working
the rx and tx need to be swapped. The instructions clarify that. Make sure tx is connected to rx. And make sure rx is connected to tx
the driver for your usb adapter is missing. Install the correct driver. Device manager should not have a warning for the device.
Do those two things and it’ll work
what happens when you scan for new devices ?
