2 Wireless considerations
2.1 Power up sequence
The Wireless Gateway should be installed and functioning properly before
any wireless field devices are powered. Install the Power Module,
SmartPower™ Solutions model number 701PBKKF into the Rosemount 702
Transmitter to power the device. Wireless devices should be powered up in
order of proximity from the Gateway, beginning with the closest device,
then working outward from the Gateway. This results in a simpler and faster
network formation. Enable Active Advertising on the Gateway to ensure new
devices are able to join the network faster. For more information see the
Emerson Wireless 1410S Gateway.
2.2 Antenna position
The antenna should be positioned vertically, either straight up or straight
down, and it should be approximately 3 ft. (1 m) from any large structure,
building, or conductive surface to allow for clear communication to other
devices.
Figure 2-1: Antenna Position
2.3 Conduit entry
Upon installation, ensure each conduit entry is either sealed with a conduit
plug using approved thread sealant, or has an installed conduit fitting or
cable gland with appropriate threaded sealant.

4 Device network configuration
In order to communicate with the Wireless Gateway, and ultimately the host
system, the transmitter must be configured to communicate with the
wireless network. This step is the wireless equivalent of connecting wires
from a transmitter to the information system. Using a Field Communicator
or AMS Wireless Configurator, enter the Network ID and Join Key so they
match the Network ID and Join Key of the Gateway and other devices in the
network. If the Network ID and Join Key do not match that of the Gateway,
the Rosemount 702 Transmitter will not communicate with the network.
The Network ID and Join Key may be obtained from the Wireless Gateway on
the Setup Network Settings page on the web interface, shown in Figure 4-1.
