SureCross Wireless Network
Product Manual
Installation
Increase the Height of the
DX80 Units
Position the external antenna vertically
for optimal RF communication. If
necessary, consider changing the
height of the SureCross radio, or its
antenna, to improve reception. For
outdoor applications, mounting the
antenna on top of a building or pole
may help achieve a line-of-sight
radio link with the other radios in the
network.
Quick Tips
A clear path increases separation range and performance
Collocation Issues
When the radio network’s master device is located
too close to another radio device, communications
between all devices is interrupted. For this reason,
do not install a SureCross Gateway device within two
meters of another SureCross DX80 Gateway or Node.
Be Aware of Seasonal Changes
When conducting the initial Site Survey, the fewest
possible missed packets for a given link is better.
However, seasonal changes may affect the signal
strength and the total signal quality. Radios installed
outside with 50% missed packets in the winter months
may have 80% or more missed packets in the summer
when leaves and trees interfere with radio reception.
Create a Clear Communication Path
Wireless communication is hindered by radio interference and
obstructions in the path between the transmitter and receiver. To
achieve the best radio performance, carefully consider the installation
locations for the Gateways and Nodes and select locations without
obstructions in the path.
For more information about antennas, please refer to the Antenna
Basics reference guide, Banner document p/n 132113.

During spring and summer, leaves may
block more of the radio signal.
A good signal strength in winter doesn’t
always mean you’ll get the same signal
strength the rest of the year.
