Configuring Multiple Modules to Use the Same Radio Settings

Please note that when you pair to a remote module the base station adopts the radio channel and group key of
the remote module.
To set the group key for a set of remote modules you can either:
Pair to each one in turn and set their radio channel and group key
or
Configure the base station by holding the shift key and clicking the Pair button on the
configure the base station to the required
page to pair to each module in the set to configure their radio settings to match the base station.

ID and Data Tags

To configure a module its ID is used in communications. This is a unique 6 character identifier, such as FF1234,
which is allocated at the factory. This ID is hexadecimal so can consist of numbers 0-9 and letters A-F.
If a module is a Transmitter it sends messages without broadcasting its ID. It identifies messages by using a Data
Tag. This tag is a 4 character hexadecimal number and can be configured by the user. When modules leave the
factory this data tag is set to the last 4 characters of its ID.
When Receiver modules or software want to use messages sent by Transmitter modules they identify the
message they want by this Data Tag.
The reason Transmitter module messages are identified by a Data Tag rather than the unique ID is that this allows
replacement of a Transmitter module without having to reconfigure the many Receiver modules that may be
using its messages. It is only necessary to configure the replacement Transmitter module with the same data tag,
radio channel and group key and the rest of the system will not notice the difference.

Transmitter Module Modes of Operation

Normal

Normal mode involves taking a reading and sending a message then entering into a very low power state before
taking the next reading to maximise battery life.
Because it is not possible to communicate with the Transmitter module during this low power state a
'configuration' mode is required.

Configuration

Configuration mode forces the modules to pause in sending their messages and to disable their low power state
to enable configuration to take place. This is easily achieved by 'Pairing' when using the T24 Toolkit software.
Once configuration is complete the modules will resume their 'normal' mode operation.

Sleep

The last mode is sleep. Modules can be sent to sleep by other modules or they can go to sleep themselves when
their messages are no longer being used. See
When sleeping, the modules can be awakened on demand by other modules or software via the base station.
