ESP-4 MI Serial Hub
 |
Connect and manage serial devices over IP. ESP multi-interface serial hubs allow serial devices to become IP-enabled using RS-232, RS-422 and RS-485 protocols for industrial/manufacturing environments and commercial applications. It's the ideal solution for reliable and cost-effective serial connectivity at the point of need.
|
The 4-port ESP-4 MI multi-interface serial hub provides serial
over IP access, allowing devices to be placed at the point of
need. Windows, Linux, and UNIX applications are able to access
network-attached peripherals as if they were directly connected.
Installation is quick and simple with structured cabling
benefits. Serial COM ports for new devices can be connected in
minutes "on the fly" and do not require opening your server or
interrupting operations. Simply attach the ESP serial hub to
twisted-pair Ethernet and load the device driver on the server.
In addition to COM port redirection, ESP serial hubs offer RAW
TCP, serial tunneling, modem emulation and Telnet modes of
operation. When configured to work in tandem, two ESP serial
hubs act as a virtual serial cable across IP networks. The
onboard Telnet server enables Telnet clients to access console
ports of serially-managed devices.Browser-Based Management
An internal web server offers a secure means to configure and manage ESP serial hubs as well as ESP-View, a built-in Java-based tool for remote diagnostics of cabling and device malfunctions.
