How to Buy

The Digi Connect ES serial server provides mission-critical serial over Ethernet connectivty. It is the first IEC 60601/EN60601 compliant device of its kind and consists of four or eight galvanic isolated RS-232 serial ports, with a 10/100 Mbps network interface and Ethernet switch. Connect ES is used in applications which require galvanic isolation and 60601 compliance to provide Ethernet connections from serial devices to a central data management system.

Galvanic isolation provides extended electrical safety. There is no electrical path from port to port, preventing a ground fault from disrupting the operation of the Digi Connect ES serial server or of any device connected to it. Similarly, there is no electrical path for current to earth ground, ensuring no electrical shock when making physical contact with the Digi Connect ES.

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."
