Product Overview
The Viconics wireless survey tools are intended to verify
and validate the deployment and use of the Viconics
wireless controllers on a potential job site.
Included in this package you will find the following items:
• 2 x Survey devices: SUR-A-5000 & SUR-B-5000
• 2 x 120 Vac charger for the tools
Before performing a survey, please insure that
both survey tools are fully charged overnight.
The survey tool will display a numerical percentage
value on the LCD screen which represents the wireless
network ZigBee RSSI dBi value (Receiving Signal Strength
Indicator).
Please note that it is normal for the value to
fluctuate slightly (up to 10-20%). The final
reading value is representative of the median
averaged values displayed.
• Any value from 10 to 100% indicates good ZigBee
connectivity.
• Any value below 10% “may” indicate that
an extra Router VRP5000W1000W may need to
be installed.
ZigBee Mesh Network Overview
ZigBee is a specification for a suite of high level
communication protocols using small, low-power digital
radios based on the IEEE 802.15.4-2003 standard for
wireless personal area networks (WPANs).
Mesh networking is a type of network where each node
in acts as an independent router. It allows for continuous
connections and reconfiguration around broken or
blocked paths by “hopping” and “re-meshing” from node
to node until the final destination is reached.
General characteristics of the wireless physical
communication layer are:
• Uses a wireless physical layer of 2.4GHz with a data
rates of 250 kbps
• Yields high throughput and low latency
• Automatic topology configuration: star,
peer-to-peer, mesh
• Handshake protocol for transfer reliability
• Range: 50 feet / 15M typical (up to 100 feet / 30 M
based on environment)
