Product: ESP-2 MI Serial HubManufacturer: Equinox SystemsAddress: One Equinox Way               Sunrise, Florida 33351Telephone: 800-275-3500URL:

The Equinox ESP-2 MI is a compact Multi-Interface, 2-port serial hub that provides versatile support of RS-232/422/485 protocols for industrial/manufacturing environments and commercial applications, including hospitality, medical and security access control operations. Through direct connection with the ESP-2 MI, serial peripherals without LAN ports can be enabled to function as IP-based devices. Using Equinox software driver technology, operating systems can transparently access serial COM ports as if installed within the server locally -- while the server actually remains securely isolated in back-office or remote locations.

The two-port unit operates independent of specific network operating systems and protocols and provides for easy and reliable network access of serial devices, eliminating the cost burdens imposed by extensive cable runs and dedicated computers for applications support. The compact size of the ESP-2 MI enables connectivity to almost any serial device anywhere while satisfying the rigorous environmental demands and unique needs of the industrial/factory automation marketplace. The ESP-2 MI, which was unveiled at LinuxWorld in New York in January 2003, is priced at $349 for a single unit.

Benefits & Features
  • Serial signaling support for RS-232, RS-422 and RS-485 RS-485 configurable for RTS or Automatic Data Detection Control (ADDC enables simplified RS-485 half-duplex control for multi-drop applications)

  • Convenient single port option allows users to hide unused ports in network topology views

  • Versatile mounting capabilities enable quick deployment in desktop, wall mount and/or DIN-rail environments

  • Durable enclosure for Industrial Automation applications

  • Surge protection for each port up to 15,000 volts ESD

  • Multi-host attachment allows for high availability solutions
