Battery Replacement

The remote unit utilizes a CR2032 lithium button cell. In

normal use with five 2-second activations per day, the

battery provides approximately two years of operation.

To replace the battery, remove the access cover by

pressing firmly on the label area and sliding it off. Once

the unit is open, remove the battery by sliding it from

beneath the holder. Replace it with the same type of

battery while observing the polarity shown in Figure 7.

There may be the risk of explosion if the battery is

replaced by the wrong type.

Joining a Transmitter

The handheld transmitter is associated with a receiver using the built-in

Join Process. This process configures a star network with the central unit

as the system Administrator. Other units are added to the network as

nodes one at a time. Typically, the handheld transmitter is added as a node

to a module that has been configured as an administrator.

is shown in the Typical Applications section. The transceiver is set as an

Administrator by pressing and holding the PAIR button for 30 seconds.

While the button is held, the MODE_IND line is on. After 30 seconds, the

MODE_IND line repeats a double blink, indicating that the operation has

begun. When the button is released the key and address generation are

complete and the module is an Administrator. A full explanation of this

The handheld transmitter is joined to an

Administrator by pressing and releasing

the PAIR buttons on both units. The

modules automatically search for each

other using a special protocol. When they

find each other, the administrator sends

the node the encryption key, UMASK

and its network address. The UDESTID

is set to the address of the administrator.

The values are encrypted using a special

factory-defined key. Once the JOIN

process is complete, the MODE_IND blinks on both units and they now

operate together.
