Description
Our USB to RS232/RS422/RS485 adapters are an easy way to connect serial devices to a USB port on your computer. They support RS232, RS422 and RS485 modes.
These adapters offer a great deal of flexibility as they can be switched to RS232, RS422 or RS485 mode and so are suitable for a wide range of applications. Each port has options such as termination and biasing for RS485 and indication LEDs for Power, Tx and Rx for easy diagnostics.
The single-port model can be switched to RS232, RS422 or RS485.
On the 8-port and 16-port versions, each port can be switched to RS232, RS422 or RS485 modes individually allowing a mixture of devices to be connected.
With their multiple serial modes and easy to install drivers for a range of operating systems, these adapters are ideal for adding one or more RS232/RS422/RS485 ports to your computer.
