Best Practice For Wireless Communication - Renkforce 2203406 Bedienungsanleitung

9. Best Practice for Wireless Communication

To ensure 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 follow-
ing best practices for trouble free wireless communication.
• Electro-Magnetic Interference (EMI). Keep the console several feet away from computer monitors and TVs.
• Radio Frequency Interference (RFI). If you have other 433/868/915 MHz devices and communication is intermit-
tent, try turning off these other devices for troubleshooting purposes. You may need to relocate the transmitters or
receivers to avoid intermittent communication.
• 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.
• 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.
