◆ ESP MI serial hubs allow serial devices to
become IP-enabled using RS-232, RS-422
and RS-485 protocols for industrial/manu-
facturing environments and commercial
applications.
◆ Auto install for quick and consistent
installations without on-site technical staff.
◆ RS-485 Multi-drop modes include RTS,
ADDC, half-duplex.
◆ Multi-host attachment allows for high
availability solutions.
◆ ESP-2 MI and ESP-4 MI allow selectable
connection methods including Telnet Server,
COM Redirection Raw TCP Client/Server,
Serial Tunneling. Only COM Redirection on
the ESP-8 MI.
◆ The ESP-2 MI and ESP-4 MI serial hubs
include an internal web server which offers
secure configuration and management.
◆ The ESP-2 MI and ESP-4 MI serial hubs’
‘Single’ mode preserves host resources when
only one port is required.
◆ The ESP-2 MI has a power input option
(detachable barrel connector and latching
screw-block.
◆ The ESP-4 MI and ESP-8 MI serial hubs’
signaling is soft selectable for flexibility.
ESP Multi-Interface Serial Hubs
Available in 2, 4 and 8 port models, ESP multi-interface (MI) serial hubs
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. For
solutions requiring one or two port connections, the compact
ESP-2 MI 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 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. 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 power
ful management software
applications, which include EquiView Plus for Windows and ESPDIAG for Unix and Linux.
