Considerations before transmitter installation

1.5.1

Wireless considerations

Power up sequence
The Smart Wireless Gateway (Gateway) should be installed and functioning properly before any
wireless devices are powered. Install the power module, SmartPower Solutions, model number
701PGNKF green power module, into the 3051 to power the device. This results in a simpler and
faster network installation. Enabling Active Advertising on the Gateway ensures that new
devices are able to join the network faster. For more information see the Smart Wireless
Gateway Reference Manual (Document No. 00809-0200-4420).
Antenna position
The antenna is internal to the pressure transmitter. To achieve optimal range, orient the
transmitter with the sensor horizontal and the power module closest to the ground as shown in
