Is it possible to connect an FT232RL USB-to-serial adapter to an EZB controller using the UART TX, RX, and GND pins, instead of connecting to the camera port with those same pins? I've attempted this setup without success. I assume there's a difference between the UART pins and the camera port pins. I'm utilizing the Connection robot skill in this setup.

EZB Connection
by Synthiam
Connects EZ-B I/O controllers to ARC via COM or IP (5 connections). Supports init scripts, battery monitoring, TCP/EZ-Script server and serial/I2C.
Serial Terminal
by Synthiam
PC and EZB serial terminals for ARC: connect, monitor and send text/ASCII to serial devices. Supports COM, flow control, baud, DTR/RTS, hex
Check the ezb v4 data sheet to see the pinout of the camera cable. It requires power, and gnd, which most uart usb adapters provide. Then connect the tx to the rx, and rx to the tx. In the camera robot skill, you can select a com port for the camera. It’ll use the com port for the video.
that’ll let you keep rocking the ezrobot camera
Also. this is a lengthy thread but the verdict on what usb to uart adapter is needed is mentioned: https://synthiam.com/Community/Questions/USB-connection-to-EZB-V4-21014?commentPage=9
looks like what you'll run into is not all the usb to uart adapters can support the 3,333,333 baudrate.
As some background, I have used FT232RL adapters successfully on 3 of my robots. And of course they all needed a USB camera to replace the EZ camera. Thanks for your insights though.
If that’s the case, that adapter won’t work for the cameras baudrate with Jeremie’s tests.
I'll try one of these... USB to UART TTL Adapter CH343G Chip 6Mbps
Make sure it has a returnable option, because a max speed of 6 MB doesn't necessarily mean it can clock to 3,333,333. Lemme know how it works
I've never heard of the CH343G, but I'll look into it.
The only USB-TTL adapter that I found to work at 3.3Mbaud was the Prolific PL-2303HXD - Had to be specifically the 'D' version.
I tried the CH343G with the EZB camera, but I am not sure what settings might make it work, At the moment the PC sees COM9 but the camera will not operate.
