Appendix B: Optimum RF Reception Guidelines

Many factors can affect the reliability of RF communication between an RF gateway

and an RF touch screen. While an effort has been made to determine operating

specifications, some specifications are not constant. RF Communication can be

limited by several factors including but not limited to EMI (electromagnetic

interference), intervening objects, antenna orientation and receiver placement. To

obtain maximum reliability and performance, some basic rules for installing RF

transceivers are listed below.

Minimize Interference

RF reception range can be hindered by spurious EMI noise that may interfere with or

mask the desired frequency, thereby reducing useable range. EMI is generated by

any electrical device at various RF noise levels depending on the device. Sources of

EMI include computers, video equipment, digital processors, lighting dimmers,

lighting ballasts, motors or any large AC source. Every effort should be made to

separate any RF transceiver from these sources of RF noise including Audio Visual

equipment in racks. If a gateway must be installed in an equipment rack, make sure

there is ample separation between the equipment and the gateway.

Gateway Placement

Optimum reception for any RF transceiver is obtained by installing the gateway

transceiver in an open area or shelf with a clear line of sight (no obstructions

between gateway and receiver). Crestron recommends that the gateway is at least

five to six feet high for best results. Avoid placing transceivers or transmitters at a

low height or on the ground. Placing RF equipment near metal objects, walls, corners

or metal enclosures compromises RF propagation and reception. Try to avoid

installing gateways in equipment racks, service rooms, electrical closets or in rooms

other than that which the panel is located.

Antenna Orientation

The antenna orientation on Crestron gateways has considerable effect on range and

reliability. The best orientation is unique to each installation. There are three possible

antenna orientations:

 Point the antenna horizontally (parallel to the ground)

 Point the antenna vertically.

 Point the antenna at a right angle to the gateway.

Never point the antenna downward as this decreases range and reliability. Refer to

illustrations on the following pages for examples of the different antenna

orientations.

NOTE: RF propagation is best from the sides of the antenna.
