ESP Multi-Interface Serial Hubs

Serial Ports Over IP: Serial Connectivity At The Point of Need

ESP multi-interface (MI) serial hubs, available in 2, 4 and 8 port models, allow serial

COM/TTY ports to be placed at the point of need, anywhere on a local or remote LAN.

These hubs allow Windows, Linux, AIX or SCO applications to communicate transparently

with network-attached serial devices, as if they were directly connected. Custom applications

are not required.

For solutions requiring one or two port connections, the compact ESP-2 MI serial hub

provides serial over IP connectivity while satisfying the rigorous environmental demands

and unique needs of industrial/factory automation applications.

ESP serial hubs permit structured wiring, thus reducing the need for costly and troublesome

long-haul serial cabling.

In addition to COM port redirection, the ESP-2 MI and ESP-4 MI serial hubs offer serial

tunneling and Telnet modes of operation. When configured to work in tandem, two units

act as a virtual serial cable over IP networks. The onboard Telnet server enables Telnet

clients to monitor and manage serially attached devices.

Browser-based Management

An internal web server offers a secure means to configure and manage the ESP-2 MI and

ESP-4 MI serial hubs. All ESP serial hubs support Equinox powerful management software

applications, which include EquiView Plus for Windows and ESPDIAG for Unix and Linux.
