• Yocto-RS485-V2

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

It can send and receive data on a RS485 bus. In addition, it can also autonomously query devices (for instance using MODBUS) and interpret the received replies to expose them 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.

The device is electrically isolated: it can be connected on an RS485 bus using a different ground circuit. The Yocto-RS485-V2 conforms to ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E) standards. In addition, the connection to the RS485 bus is protected against ESD up to ѱ6 kV (contact) and against electrical fast transients up to ѴkV.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
