Owner's manual

Test your system before permanent mounting
Before permanently mounting your transmitters in your application try moving
the devices to different locations and mounting angles to determine what
installation achieves the best signal strength.Move your system components
higher off the floor and away from exterior walls
Avoid installing your system components to close to the floor or near your
buildings exterior walls. The closer your transmitter and receiver unit are the
greater the interference and lose of signal strength will be.
Maintain a line of sight (LOS) between antennas
Maintaining a line of sight between your transmitter and receiver unit will
produce greatly improved signal strength over a system were the antenna’s in
your system have obstacles blocking them.
Maintain a constant ambient temperature environment
Maintaining a constant ambient temperature environment is important to
achieving maximum signal strength. Exposing your system components to
extreme hold or cold temperatures, or sudden changes in ambient conditions
will have an effect on the performance of your system.4.6.1 Operation in
Buildings
Your transmitter sends wireless data transmissions to a receiver connected to
your PC. Radio signals are electromagnetic waves. A radio signal becomes
weaker the further it travels. Range is decreased by different types of materials
found in the direction of the signals propagation. Radio waves can penetrate
most types of wall materials, but they are dampened more than they would be
by a direct line-of-sight installation.
Avoid dampening materials by repositioning the transmitting and/or receiver.
4.6.2 Penetration Angle of Radio Waves Through Walls
The angle at which the transmitted radio signal hits a wall is very important and
also has a big effect on maximizing range. Signals between your transmitter
should be transmitted as directly as possible.
4.6.3 Building Materials
Examples of how different types of wall material may reduce your signal:
Material Type Possible Signal Reduction
Wood, Plaster, Sheetrock, Uncoated 0 to 10%
Glass w/o Metal, Fiberglass
Brick, Pressboard 5 to 35%
Reinforced Concrete 10 to 90%
Metal Walls, Metal Doors, Elevators,
Metal Stair Cases, Metal Piping, 90 to 100%
Metal Mesh, Metal Screening
Avoid dampening materials by repositioning the transmitting and/or receiver.
