This device is an USB to RS485 adapter, that does not require a driver and does not install a virtual COM port. 

It is able to send and receive data on a RS485 bus. In addition, it is also able to autonomously query devices (for instance using MODBUS) and interpret the received replies to expose them as if they would come from a Yoctopuce sensor, with all inherent advantages: unique identifier, polling, callbacks, datalogger. 

Be aware that this device will not work with applications designed to use a COM port: it is designed to be used with Yoctopuce API only. 

The device is electrically isolated, which means it can be connected on a RS485 bus using a different ground circuit. The Yocto-RS485 conforms to ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E) standards, and provides a ±15 kV ESD protection on RS-485 input/output pins.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.

USB cables and enclosure to be ordered separately.
