The PS810 is a versatile 8-port serial-Ethernet communication device. The HelloDevice Pro Series supports RS232, RS422 or RS485 on each serial port allowing virtually any asynchronous serial device to be accessed over a network. With the rich broadband network connectivity protocols such as DHCP, PPPoE and Dynamic DNS, you could easily manage the legacy serial devices over broadband Internet by using DSL or cable modem connection. The built-in Dynamic DNS protocol of the HelloDevice Pro Series enables you to access the serial devices with their domain names. Thanks to its inner Linux OS, the PS810 has the similar easy-to-use user interface that Linux machines have. They provide you with a full-featured system management functionality.
