Connecting to an Ethernet Gateway (EGX)
The POWERLOGIC Ethernet Gateway is a network communications
interface that performs protocol conversion between POWERLOGIC-
compatible devices and standard Ethernet network protocols.
An Ethernet Gateway has serial ports that support from 8 to 32
POWERLOGIC devices, depending on the Ethernet Gateway model.
More devices can be daisy-chained when a signal repeater is used.
Refer to the instruction bulletin that ships with your Ethernet Gateway
for more information and installation procedures.
