This device is a USB to serial adapter, similar to RS232 but it uses logical (TTL/CMOS) signal levels at 0/3.3V or 0/5V. It does not require a driver and does not install a virtual COM port.
It can autonomously interpret serial data coming from any external serial board and expose measures as if they were coming from a Yoctopuce sensor, with all the inherent advantages: unique identifier, polling, callbacks, data logger. Be aware that this device does not work with applications designed to use a COM port: it is designed to be used with Yoctopuce API only.
If needed, the device can also provide a 3.3V or 5V voltage source to power the external serial board. The 3.3V source can provide up to 200mA.
The device can work with standard logical levels (signal high when the line is idle), or with inverted levels. RTS/CTS can only be used with standard logical levels. The device can also analyze a serial bidirectional communication between two tiers without interference.
If you need to interface a serial port working with RS232 levels, choose a Yocto-RS232.
