This device is a USB to RS232 adapter, that does not require a driver and does not install a virtual COM port.
It can autonomously interpret serial data coming from any RS232 appliance 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 the Yoctopuce API only.
The device is electrically isolated, which means that it can be connected without risk to an appliance powered on a different circuit. The Yocto-RS232 conforms to the 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 an RS232 bidirectional communication between two tiers without interference (using two input channels), but the adapter for this usage is not included (check the accessory list below).
If you need to interface a serial port working with CMOS/TTL levels, choose a Yocto-Serial.
USB cables and enclosures to be ordered separately.
