Fast, Secure and Reliable
The MultiNet Family is a line of industrially-hardened serial port
servers that provide access for serial devices onto a TCP/IP Ethernet
network. Designed to meet the unique networking and environmental
requirements of the Protection & Control industry, MultiNet devices
ensure continuous connection with and control of serial devices
through your communications network. The MultiNet family of devices
are designed and built to meet the needs of the utility industry, and
are tested to the same environment and conditions as all GE Multilin
devices to deliver a solution that maximizes the availability of your
critical infrastructure.
High Density Solution for Any Serial Devices
MultiNet4 provides devices with serial ModBus to ModBus TCP/
IP communications capability on an Ethernet network, allowing
connection to LAN and WAN network systems via fiber or wire media.
MultiNet4's four serial ports have the capability to connect up to
128 serial devices, which eliminates complex wiring and additional
communications converters.
In order to ensure fast access to serial device data, MultiNet4 features
individually-configurable serial ports that can be set to work at
different speeds and even with different Modbus TCP port settings,
enabling optimization of serial data collection. MultiNet4 has been
environmentally hardened to withstand severe utility and industrial
conditions, and with a variety of mounting options, the device can be
placed anywhere it is required to work.
Add Ethernet to ModBus Devices
In addition to connecting serial devices to the
network, MultiNet4's built in 4-port Ethernet switch
provides highly reliable network connectivity, both
upstream to SCADA and management applications,
as well as downstream to other Ethernet devices.
With options for 100Base-FL fiber optic interfaces
MultiNet4 is designed for applications where long
cable runs, EMI/RFI immunity, and the inherent
electrical isolation that optical fiber offers is
required. With multiple options for connection
port types, MultiNet4 can connect to almost any
Ethernet device and ensures connectivity through
fast recovery from broken links using Link Loss Alert
(LLA). In addition, the built-in 4-port Ethernet switch
is fully-managed and configurable and provides
users with the ability to finely control, view, and
manage MultiNet4 as part of the network. The
MultiNet switches support most 802.1 network
management features and are configurable using
either Command Line Interface (CLI) or our Web
Management Interface. Management functionality
