WiNG Alternate Channel Communications Guide
Thank you for purchasing a WiNG monitoring system. This document guides you through
the alternate channel setup process.
Additional support information is available at rletech.com. Before you install a WiNG
system, check the website to ensure you are using the most recent version of our
documentation.
If you need further assistance, please contact RLE Technologies at [email protected].
WiNG Alternate Channel Communications
Most WiNG system deployments operate well with the out-of-the-box default settings. There are, however, instances where excess RF energy
in a facility crowds the default channels. For this reason, the WiNG system was designed with a set of alternative communications channels.
While it is not difficult to switch the channels on which your system is communicating, it is outside the basic WiNG configuration scope. For this
reason, we are providing a specialized set of instructions and encourage you to contact our technical support staff if you have any problems
configuring alternate channel communications.
Sensor Communications
By default, WiNG sensors communicate via channel pair 1. You can determine on which channel pair your sensor(s) are communicating by
looking at the status LED on the front of the sensor enclosure. This LED blinks randomly once every 10 - 20 seconds.
Blink Pattern
System Frequency
Status Description
Blue / Off, Every 10 - 20 seconds
900MHz
Operating on channel pair 1 (default)
Green / Off, Every 10 - 20 seconds
900MHz
Operating on channel pair 2
Purple / Off, Every 10 - 20 seconds
868MHz
Operating on channel pair 1 (default)
Yellow / Off, Every 10 - 20 seconds
868MHz
Operating on channel pair 2
Change the Sensor’s Channel Pair
1. Hold the sensor in your hand and locate the LED on the top of the enclosure. Make sure the LED on the board is blinking blue (900MHz)
or purple (868MHz) to indicate it’s currently communicating via channel pair 1. Now look down the side of the enclosure past the LED
(the left side of the enclosure) and find the small hole in the middle of the bottom left side of the enclosure - right where the lid meets
the base. If you look inside this hole you will see a small black button. You will use this button to change the channel pair of this sensor.
2. Insert a small non-conductive tool - like a toothpick - inside the hole and push the black button three times consecutively. The 900MHz
and 868MHz devices each have a different blink pattern for channel transition:
•
900MHz sensors: The LED on the sensor board blinks blue with the first push, blue with the second push, and green with
the third push. It will then blink green three times in a row to indicate the sensor has switched to channel pair 2 for its
communications.
•
868MHz sensors: The LED on the sensor board blinks purple with the first push, purple with the second push, and yellow
with the third push. It will then blink yellow three times in a row to indicate the sensor has switched to channel pair 2 for its
communications.
3. Pause a minute and watch the sensor LED. Once the transition pattern of blinks are complete, it blinks randomly, once every 10 - 20
seconds. Wait until it blinks green (900MHz) or yellow (868MHz) once to ensure channel pair 2 communications are active.
4. You can change the sensor back to channel 1 communications in the same way. If the sensor is operating on channel pair 2 (LED is
blinking green (900MHz) or yellow (868MHz)), push the black button three times consecutively.
•
900MHz sensors: The LED blinks green with the first push, green with the second push, and blue with the third push. Then it
blinks blue three times in a row to indicate it’s communicating on channel pair 1. Pause a minute to watch the LED and ensure
it’s blinking blue in its random blink cycle.
•
868MHz sensors: The LED blinks yellow with the first push, yellow with the second push, and purple with the third push. Then it
blinks purple three times in a row to indicate it’s communicating on channel pair 1. Pause a minute to watch the LED and ensure
it’s blinking purple in its random blink cycle.
5. If you remove or change the sensor’s battery it will revert to the default channel pair 1 (blue (900MHz) or purple (868MHz) blinking light).
Manager Communications
By default, the WiNG-MGR communicates via channel pair 1. If you change the channel pair on which your sensors are communicating, you also
need to change the channel pair on which your manager is communicating.
