Ranger Pro Gateway device managers limit the number of field devices connected to the
gateway. This could be any combination of
IO
,
Router
, or
Router IO
devices up to a total of 50
devices. Up to 9 child devices may connect to each router enabled device. The maximum
number of hops between the Ranger Pro Gateway and a Ranger Pro field device should be
limited to 4.
Move the Device or Gateway
Relocating a field device or reorienting its axis or orientation relative to the gateway as little as 6
cm (2 1/3 inch), or one-half of a 2.4 GHz wavelength, may improve signal strength.
Change Gateway
Change the gateway deployment by using the authorized 6dBi higher gain antenna on the
gateway. Verify that the resulting narrowly focused radio frequency distribution pattern meets
your needs. You can also add additional gateways.
Verify Signal Strength
Check that the devices' signal strength and packet error rate are within guidelines. Use your
Ranger Pro Gateway web interface to monitor device signal strength and packet error rates.
Signal strength (RSSI) should be above -85 dBm, and preferably above -78 dBm.
Validate Device Data
Using the Ranger Pro Gateway device-manager web-interface, verify the publication status and
that the measurements are displayed in the
Readings
tab.

Initial publication of measurements may take some time after devices have joined the
network. After the initial period, during which the network is forming, measurements will
be published at 1-minute intervals.
