You must reset the receiver unit to factory defaults before linking the transmitter and receiver
units.
To reset the default factory configuration:
1. Press and hold the RSSI push button.
2. Power on the WI-I/O 9-L-R receiver.
3. The WI-I/O 9-L-R receiver flashes all LEDs at medium flash (i.e. 1.6 Hz).
NOTE: If the LEDs do not flash, you must repeat steps 1 and 2 until the LEDs flash before
continuing.
4. Release the RSSI push button within 5 seconds.
5. Within a further 60 seconds, press and hold the RSSI push button for 5 seconds (until
the LEDs stop flashing) and then release.
6. The WI-I/O 9-L receiver lights all LEDs for 2 seconds before returning to normal
operation.
NOTE: If the LEDs do not light, you must repeat the process from step 1 until the LEDs
light before continuing.
7. You can now link the transmitter and receiver units.
You must reset the transmitter unit to factory defaults (to disable encryption) before linking the
transmitter and receiver units. For more information, see the WI-I/O 9-L-T Transmitter Quick
Start Guide.
NOTE: You must complete the linking process in 60 seconds.
To link the transmitter and receiver units:
1. Press and hold down the RSSI Pushbutton on the receiver.
2. Power on the receiver while holding down the RSSI Pushbutton
3. Release the RSSI Pushbutton as soon as the Receiver LEDS flash (within 5 seconds
of powering the receiver).
4. The receiver will flash all LEDs for a maximum 60 seconds while it tries to link to the
transmitter.
5. Power on the transmitter. The transmitter sends a special “Link” message to allow the
receiver to recognise the transmitter.
6. When the units link, the receiver lights all LEDs for 2 seconds before returning to
normal operation.
NOTE: If the receiver LEDs continue flashing within the 60 seconds, the units are not
linked and you should retry the linking process by powering the transmitter off and on
again. If you exceed the 60 seconds, you must restart the linking process from step 1.
7. You can now bench test your configuration before deploying.
