Universal; High-Performance Rs-232/422/485 Serial To Ethernet Connectivity

PortServer TS MEI provides switch-selectable RS-232/422/485 serial port connectivity; making it easy to connect multiple serial devices to your network. It combines the inherent benefits of data networking with proven asynchronous connectivity to deliver powerful yet simple Ethernet connections for all of your serial devices. Digi's patented RealPort; with encryption and user authentication; makes it possible to establish a connection between the host and networked serial device by creating a local COM or TTY port on the host computer; allowing software applications to work with networked device servers instead of requiring a host adapter. Powerful features including data security via SSHv2; port buffering and full SNMP management; making PortServer TS MEI ideal for applications like console management where device management and monitoring are critical.
