One Simple Communications Solution
MultiNet is a communications module that provides serial devices with
communications over Ethernet, allowing connection to fiber optic LAN
and WAN network systems. MultiNet has the capability to connect
up to 32 serial devices eliminating complex wiring and additional
communications converters, and providing a streamlined and
economical Ethernet hub. Unlike most communications converters
that are designed for commercial use, MultiNet is environmentally
hardened to withstand severe utility and industrial conditions.

Easily Add Ethernet to ModBus Devices
MultiNet gives you the ability to connect ModBus serial devices to new
or existing Ethernet networks. It has a 10BaseF fiber optic interface
that provides high EMI/RFI immunity and inherent electrical isolation
over long cable runs. MultiNet setup is simple, with a Windows-based
software program for installing and configuring the communication
drivers.
MultiNet is Compatible with GE Multilin IEDs
MultiNet provides a simple way to add Ethernet communications to
your existing devices, and its convenient size can be accommodated
easily in any panel. MultiNet can be used with any GE Multilin ModBus
IED including:
· PQM/PQMII-PowerQualityMeter
· SRFamilyIEDs
· MFamilyIEDs
· ALPS-AdvancedLineProtectionSystem
· DDSFamilyIEDs
Industrial and Utility Environments
MultiNet is designed for industrial and utility applications. Unlike
traditional communication devices, MultiNet is industrial hardened to
withstand the harshest environmental conditions.
