3.5.1 Pairing between remote control and receiver
In order for remote control and receiver to talk to each other, both must have a same ID.
There is a 24-bit ID in both the remote control and receiver. This ID is stored in the
Eeprom
There are 2 scenario when the ID can be written/overwritten:
3.5.2 In the factory, before delivered to customer.
All the receiver and remote control has the same ID, which is default ID ( equivalent to
no ID in Eeprom ) . So, when the customer buy the receiver and remote control, they can
straight away use it without any setup required.
3.5.3 Pairing by the user
Since all the remote control and receiver has the same ID, there could be a scenario
where the remote interfere the receiver that is used by other user at the same time. In this
case, the user has the option to change this ID on the remote and receiver. This is done by
the following receiver.
¾Make sure the USB receiver is unplugged from the host
¾Press and hold “Clear” key and “Enter” key for 3 seconds. Then release both
keys. The remote control now will send a special command code of pairing setup,
repeatly for 10 seconds. This command code contains a 24bit- ID ,which is
randomly generated by remote control.
¾Make sure the host is in active mode, plug in the USB receiver now.
¾When the USB receiver is plugged in, it will enumerates. After enumeration
completes, it will look for the command of pairing setup, for 1 second.

¾If it receives this pairing command, it will overwrite it’s own 24bit- ID with the
new ID in this command.
¾The USB receiver will acknowledge the successful operation to the remote
control.
¾After the acknowledgement is received by the remote control, it will overwrite it’s
own ID with this ID as well, into the Eeprom. This new ID will remain in the
Eeprom of both receiver and remote control.
¾Now, both remote control and receiver have the same ID and pairing is
