Description
The PortBox2 allows RS-232 and RS-485 serial devices to be remotely accessed over an Ethernet network. It provides a fully functional RS-232 port with all 9 signals, supporting baud rates up to 115,200 Bd. Users can configure the device via a built-in web interface or Telnet, and the free HW VSP3 software enables seamless integration into Windows as a Virtual Serial Port.
With Box-to-Box mode, two PortBox2 devices can create a transparent serial tunnel, effectively extending an RS-232/RS-485 connection over LAN. This makes it an ideal solution for industrial automation, remote monitoring, and serial device management.
