Items you can change or interact with:
Radio Channel Tabs
Click a tab to change the radio channel the base station is operating on
Clear List
Clear all detected messages from the list
Wake All
Wake all modules on the current radio channel
14
Start Logging
Asks for a filename then logs the received data to a CSV file in the following format:
Data Tag, Elasped ms, Value
View Last Log
Will launch the application associated with CSV files and open the last logged file.
Move Group Channel
If the base station has a group key set then this button will be visible. Once at least one module is present in the list this button will become enabled. Clicking it will ask the user for a new radio channel then all detected transmitters, along with all other modules on the same channel and group key such as handhelds, will all be moved to the selected channel. Once this has been achieved the base station itself will move and the list will start to fill again with messages on the new radio channel.
You will only see a list of detected transmitters on this page so
you will need to ensure that any other receiver modules in the group are available to be woken. When this button is clicked all modules on the same radio channel and group key will be woken before they are changed to the target radio channel.

Items you can change:
Name
You can enter a short description which may help you recognise this module in the future.
Some transmitter modules may have had their calibration protected. This indicates that you cannot calibrate this module.
Group Keys were introduced in 2015 so modules built before this date will not
support this feature. This indicates that the connected module can support them
This indicates that the connected module can support Group Keys and that one has been configured for this module
Applicable to a base station only. This indicates that on the Channel Monitor page modules that are sleeping will also be listed
Extended range radios were introduced to the T24 range in 2015. This indicates that the connected module has an extended range radio fitted.

Items you can change:
Low Battery Level
Click this item to set the battery low level. For the Energizer L91 cells this should be around 2.7 V.

20
Items you can change:
Channel
Select a radio channel between 1 and 15. The default is channel 1. You can use the
Spectrum Analyser mode to determine a good clean channel to use.
Group Key
Only visible on modules that support Group Keys. Only modules with identical group keys can communicate. You can isolate groups of modules on the same channel or just use the key to ensure the data cannot be read by somebody else. Early versions of T24 modules do not support Group Keys and this option will not be visible in the Toolkit.
To use modules that support Group Keys with older modules that do not then the Group Key field must be blank.
The following two options are not visible when changing radio settings for a base station. In that case changes are immediate.
Reset Module Only
Only enabled once a change has been made. When radio settings are changed they do not take effect immediately but require a reset or power cycle. This button forces the connected module to adopt the new settings but keeps the base station on the existing settings. The home page is then shown.
Reset Module and base Station
Only enabled once a change has been made. When radio settings are changed they do not take effect immediately but require a reset or power cycle. This button forces both the connected module and the base station to adopt the new changes and re-establishes a connection.
21
Items you can change:
Repeater Subgroup
Select a repeater subgroup for this module. The default is zero which will let all repeaters repeat messages from this module. See Repeaters and repeater
Subgroups
Remote Module Radio Settings Tool
To quickly set a batch of remote modules to match the radio settings of the base station you can use this tool. Usually this is arrived at by pairing with the base station by holding the shift key whilst clicking the Pair button on the Home page.
To change the remote module radio settings:
Remove remote module power Click the Click Here link on the page Apply power to the remote module
The Toolkit will remain unchanged and still paired to whatever module or base station it was paired to but the remote module will have changed its radio settings.
22
Items you can change:
Save
Click this button to open a file dialog window to allow you to select a filename and location to save the configuration file to. All configuration information including calibration data will be saved to the file. The file extension is tcf.
Restore
Click this button to open a file dialog window to allow you to select a filename and location of a previously saved file to load into the connected module. All configuration information including user calibration data will be overwritten. The file extension is tcf.

Items you can change:
Transmit Interval
Enter the transmission rate in milliseconds. The default is 333 giving approximately 3 per second which is ideally suited to reading on a handheld. You may want to slow this down to achieve longer battery life.
Sample Time
This is the length of time in milliseconds that the input is sampled before the value is transmitted. This can vary between 5 milliseconds and close to the Transmit Interval. A shorter sample time means that the module is awake for less time so battery life is increased but at the expense of a reading with less noise free resolution. You can vary this to see the effect on battery life and noise free resolution.
Low Power Mode
Unless the transmitter module is non battery powered this should be set to Yes. In between transmissions the transmitter module will enter sleep mode which,
27
for some modules such as the strain gauge transmitter module, will have a massive effect on battery life. A reason for not using Low Power Mode would be if using the module in a Master-Slave arrangement with PC for example.
Battery Type
This is not a parameter of the module but information used by the battery life guide. You can choose from either the certified AA batteries or choose custom to allow you to select your own battery capacity. See below. This will also offer to change the Battery Low Level if the level suitable for the chosen battery is not the level currently set.
Usable Capacity
This is not a parameter of the module but information used by the battery life guide. This is the capacity of the battery in amp hours and has a profound effect on battery life calculations. This capacity needs to be calculated from battery manufacturer’s data sheets to take into account that you can only use batteries down to 2.1 volts so in the case of twin AA cells this would be 1.05 volts. Generally the usable capacity will not be as high as that advertised by the battery manufacturer. Temperature and internal resistance of the battery are not taken into account in the guide.
Sensor Impedance
This is not a parameter of the module but information used by the battery life guide. Enter the resistance of the connected strain gauge in ohms.
Usage Per 24 Hour Period
Enter the number of hours per 24 hour period that the Transmitter will be awake and transmitting.
