Basic Operation
Power
The encoder can be powered in one of three ways:
•
•
•
When power is applied, the encoder runs a series of self-tests that blink the front panel
Power LED and all other indicators. The encoder then boots the NAV operating system. It
can take approximately 45 seconds for self-test and system startup to complete. When the
process is complete, the Power LED lights steadily.
NOTE: The encoder is NOT operational until the boot process is complete (the Power

One at a time, use a Tweeker or other small screwdriver to press and hold the decoder
front panel ID button for approximately 3 seconds, until the ID LED blinks. Release the
ID button. The decoder is now paired to the encoder.
Repeat step 2 for each decoder.
Use a Tweeker or other small screwdriver to press and release the encoder front panel
