7. Best Practices for Wireless Communication
Note:
To insure proper communication, mount the remote sensor(s) upright on
a vertical surface, such as a wall.
Do not lay the sensor flat.
Wireless communication is susceptible to interference, distance, walls and metal
barriers. We recommend the following best practices for trouble free wireless
communication.
1.
Electro-Magnetic Interference (EMI)
. Keep the console several feet
away from computer monitors and TVs.
2.
Radio Frequency Interference (RFI).
If you have other 433/868/915
MHz devices and communication is intermittent, try turning off these
other devices for troubleshooting purposes. You may need to relocate
the transmitters or receivers to avoid intermittent communication.
3.
Line of Sight Rating.
This device is rated at 300 feet line of sight (no
interference, barriers or walls) but typically you will get 100 feet
maximum under most real-world installations, which include passing
through barriers or walls.
4.
Metal Barriers.
Radio frequency will not pass through metal barriers
such as aluminum siding. If you have metal siding, align the remote and
console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each
“wall” or obstruction decreases the transmission range by the factor shown
below.
Medium
RF Signal Strength Reduction
Glass (untreated)
5-15%
Plastics
10-15%
Wood
10-40%
Brick
10-40%
Concrete
40-80%
Metal
90-100%
Set up display
Note:
Because of the default settings already determined by the manufacturer it
may not be necessary for the majority of users to perform
–
except the
Relative Air Pressure (see further down) - any further basic settings.
Changes, however, can be easily made.
For basic settings, the following menu is started by touching the Touch Screen in
the desired display area.
The basic settings can now be performed in the following successive order:
