Pairing Transceivers

Since the transceivers have been paired at the factory, it is highly unlikely that
they will require re-pairing. However, it may be necessary in the event one of the
transceivers requires replacement.
1. After all wiring is performed, apply 24
transceivers.
2. The base transceiver
times per second. When in this mode, the base will broadcast a pair request
message once every 5 seconds until it receives a pair response from the satellite
transceiver.
3. The satellite LED

3 seconds. Once this pattern appears on the
4. Pairing is confirmed when both transceiver
the transceivers will poll each other every 15 seconds regardless whether any
digital input signals are activated. The
message is received and go solid red when a data message is sent.
Note: When using multiple iO-
only power up one base and one satellite to be paired at a time.

Unpairing Transceivers

Unpairing a base and satellite transceiver is accomplished by holding down the
button while applying 24
seconds. While the button is held down, the

flash as described in the pairing section. If the button is released prior to the
completion of the unpairing process, the transceivers will transition to the paired
mode, retaining their previous paired status.
