AM62A7: Using USB to RS485 convertor in Evaluation kit

Part Number: AM62A7
Other Parts Discussed in Thread: AM67

Tool/software:

Hi Team,

I'm planning to do a proof of concept for a PTZ module with AM67 evaluation kit. The PTZ unit has RS485 interface for the data transmission. The Evaluation kit has USB-A ports. Will the USB-A to RS485 convertor be compatible for it?

Can i control the PTZ unit with this?

Thanks,

Preethi

    Hi Preethi,

    If this USB module implements the standard USB serial gadget function, yes it can be used in Linux to provide UART/RS485 function. However, if you plan to use PTZ modules on your final custom board, I would recommend to find a PTZ evaluation module which has RS232 interface (RXD/TXD/RS485-DE) instead of USB interface, to not bring USB software stack into the path, since it won't be used in the final product.
