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.<br><br>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.<br><br><b>Features</b><br><br>- Selectable serial signaling - RS-232, RS-422, RS-485 interfa This part is cataloged in the Federal Logistics Information System (FLIS) under NSN 5340-01-472-7841, indicating validated use in U.S. government and defense logistics supply chains.
