Anewtech Digi-Connect-ES Digi International Digi Connect ES 4SB, Digi Connect ES 8SB Serial ServerDigi Connect ES provides serial over Ethernet connectivity. It is IEC 60601 3rd Edition compliant and consists of four or eight galvanic isolated RS-232 serial ports, with a 10/100 Mbps network interface and optional Ethernet switch. Digi Connect ES is used in applications that provide Ethernet connections from serial devices to the central data management system.

Galvanic isolation provides extended electrical safety. There is no electrical path for current to earth ground, ensuring no electrical shock when making physical contact with the Digi Connect ES. There is no electrical path from port to port,  ensuring a ground fault will not affect the operation of the Digi Connect ES or the operation of any device connected to it.

Digi's patented RealPort® COM port redirector technology makes it possible to establish a connection between the host and a networked serial device by creating a local COM or TTY port on the host computer, allowing existing software applications to work without modification.

Incoming/outgoing and Telnet sessions on each port give system administrators a high level of control over networked serial devices. Other features include Secure Shell (SSH v2) encryption to protect against unauthorized network monitoring or "sniffing."
