This device is a USB to RS232 adapter, that does not require a driver and does not install a virtual COM port. 

It is able to autonomously interpret serial data coming from any RS232 appliance and expose measures 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 without risk to an appliance powered on a different circuit. The Yocto-RS232 conforms to TIA/EIA-232-F standard (-5.5V and 5.5V output, and up to -25V... +25V as input). It is therefore compatible with all standard RS232 interfaces, but it cannot be wired directly to chips using logical CMOS/TTL levels. 

The RJ12 to DB9 adapter for bidirectional communication (including CTS/RTS) is included. 

The device can also analyze a RS232 bidirectional communication between two tiers without interference (using two input channels), but the adapter for this usage is not included. 

If you need to interface a serial port working with CMOS/TTL levels, choose a Yocto-Serial.

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.
