3.4.2 Antenna position
The Emerson 781S Smart Antenna is an omni-directional antenna that does not require
specific horizontal positioning for optimal network connectivity. It should be mounted
vertically upright in the center of the network for the most direct device connections to
the Gateway.
3.5 Connecting the Emerson 1410S to the 781S
Smart Antennas
There are two main connection configurations for the Emerson 1410S and 781S Smart
Antennas: with and without intrinsically safe barriers. The hazardous location approval
option of the Emerson 781S determines whether it needs to be installed with barriers. This
connection is integrated in the Gateway electronics and can be selected upon order.
Selecting the IS barrier option will provide IS barriers integrated into the Gateway. This will
