Description

The MultiNet Serial-to-Ethernet converter is a communications module that provides GE
Multilin serial Modbus IEDs with Modbus TCP/IP communications over Ethernet. MultiNet
has the capability to connect up to 32 serial Modbus devices, eliminating complex wiring
and additional communications converters, as well as providing a streamlined and
economical Ethernet hub. Unlike most communications converters designed for
commercial use, MultiNet is environmentally hardened to withstand severe utility and
industrial conditions.
MultiNet can be used to connect an existing Modbus RTU network over RS485 onto a LAN
in order to support multiple SCADA masters or advanced HMI systems. Additionally, the
use of MultiNet greatly facilitates the setup and wiring of any serial device to a
communications center since it avoids costly RS485 cable runs. Finally, large RS485
networks are slow and have a typical limit of 32 devices. MultiNet allows customers to
expand that limit as well as improving network performance by separating large RS485
networks into smaller groups.
