Viconics VST5000 (Classic ZigBee) User Guide - Manual (Page 5)

5 VST5000W5000W Wireless Survey Tools User Guide
is designed for optimal horizontal distance
penetration. Holding the survey tool or the controller
horizontally will dramatically lower the range of
connectivity.
• Hold the survey tool at the location where you would
like to install the controller. The closer the survey tool
is to the actual installation location of the controller,
the more accurate the survey results
will be.
• Do NOT stand directly in between 2 survey tools
while measuring. Your body will interfere with
transmission signals. Always stand out of line of sight
to avoid interfering with the signal readings.
• To insure accurate readings, ALWAYS hold the tools
by the bottom using the battery holder (fig. 6). Do
not hold it by the controller case, as you may cover
the antenna (fig. 7).
Important Notes About The Survey Tools:
• The survey tools feature an auto-shutdown after
10 minutes. After 10 minutes, 10 quick audio beeps
will be heard; if the ON button is not re-pressed, the
unit after the count of 10 beeps, the unit will self
shutdown to prevent unnecessary battery drainage.
• The minimal expected battery life is at least 50 full
charge cycles. The maximum expected battery life is
200 full charge cycles.
• Contact Viconics for replacement batteries. The
survey tools use a custom rechargeable battery
type. DO NOT USE regular rechargeable batteries for
replacement; the charging circuit is NOT DESIGNED
for that. Doing so MAY result in critical failure and /
or injury.
Site Survey Overview
If available, it is best to have a floor plan layout showing
the location of all the proposed controllers to be
installed.
If possible, perform the survey during occupied hours
where other electronic devices such as (computers,
wireless laptop, cell phones, PDA’s, wireless telephones,
microwave ovens, light ballasts, etc.) would be in use as
to generate as much interference as possible.
Some of these devices can generate interference up to
20 feet or 6.8 meters away during normal operation. Even
with possible sources of signal interference, the presence
of these wireless devices will most probably not result in
any network performance degradation.
It is important to understand that the survey values given
by the survey tool are provided as a worst case scenario
of a point to point application.
Once the whole is deployed with a Jace and VWG
coordinator and all wireless controllers are present and
functioning as routers, the ability of the network to
efficiently route wireless signals cannot be compared to
this simple survey analysis method. Thus, it is important
to remember that the displayed percent signal ONLY
represents the signal strength from point A to point B.
As other devices join the network mesh, the route taken
from device A to device B will most likely change.
A dense cluster of wireless controllers will allow your
network to recover from temporary disturbances more
swiftly.
To ensure a proper survey, Viconics
recommends using ONLY channels 15 or 25 to
avoid network interference with 802.11 Wi-Fi
devices in the 2.4GHz spectrum range. Begin
by setting BOTH devices to the SAME channel
& PAN ID.
Before starting a site survey:
• Press the on button on both devices while holding
them side by side.
• 100% signal strength indicates that the survey tools
are functioning properly.
Survey Considerations:
• Always hold the survey device vertically to insure
proper measurements. The controllers antenna
