Introduction / Overview

The T24-RA is a remote acquisition module for the collection and processing of potentiometer resistance

measurements. The module measures the resistance and periodically transmits it. Between transmissions the

device is optionally in a power saving sleep mode to conserve batteries

Various devices are available that utilise the transmitted data and include handheld and PC displays etc.

Connections

This section will show you how to get the device pair working out of the box.

You will require a 3 Volt dc supply for the acquisition module which may be 2 X AA alkaline batteries.

Power

Attach power supply wiring to the module as shown below:

+ 3V Supply

0V Supply

Connect to a 3 Volt power supply or batteries.

WARNING: This module is not reverse polarity protected!

WARNING: The maximum voltage is 3.6V!

Input Connections

NOTE: The acquisition module may already be mounted in a connectivity module. In this case please refer

to the connectivity module user manual for the connection details.

Configuration

This section explains how to install software and configure the module. Please note that you will need the T24

Toolkit software and a T24-BS base station to allow your computer to communicate with T24 telemetry

devices.

Installation

T24 Toolkit

To configure the devices we must use the T24 Toolkit software application. This can be downloaded from our

web site or may be shipped with your products.

Install this on a PC or laptop.

Run setup.exe and follow the prompts to install the software.

T24-BSu Base Station

If you have a USB version of the base station (T24-BSu) then you just need to plug this into a USB socket on your

PC. If you are using an alternative base station then please refer to the appropriate manual.

Mantracourt Electronics Limited T24-RA User Manual

T24 Toolkit

The T24 Toolkit provides a means of simple configuration and calibration of the acquisition module along with

useful tools to aid integration.

Run the T24 Toolkit software application.

PLEASE NOTE: Depending on which acquisition module is selected the screenshots may vary slightly. This will generally be in naming of

units and device descriptions. The screenshots shown are those shown when a T24-PA strain gauge acquisition module is connected.

General Pages

Setup Base Station Communications

Select USB as the interface and select 1 as the Base Station Address.

In the toolkit all items that can be changed by the user are coloured orange.

To change a value just click on the relevant orange item. You will then be presented with a new dialog window

allowing you to change the value.

This may use a slider, text box or list to allow your new value to be entered.

Click the Home button to attempt communications with the base station.

If no communications can be established the toolkit will remain on this page. You will need to check that the

base station is powered and that it is connected to the converter correctly.

Home

We now have successful communications with the base station so we can now pair with our device or we can

select the Spectrum Analyser mode or Data Provider Monitor mode.

To connect to our device we will pair. This is achieved by power cycling the device. Pairing removes the need

to know the radio settings of the device you are connecting to and also ensures that it is in a suitable state for

configuration.

Pairing Procedure

Remove power from the acquisition module

Click the Pair button on the toolkit.

You now have 10 seconds to re-apply power to the acquisition module.

If you connect successfully the toolkit will change to the Information page.

If the pairing fails try again.

NOTE: Pairing with the toolkit will not change the radio configuration settings of the connected device.

Mantracourt Electronics Limited T24-RA User Manual

Analyser

The analyser page is provided as a tool and will not normally be needed unless you plan to change channels and

want to find the best channel to select, or to diagnose poor communications issues.

This page shows the radio signal levels detected across all the channels available to the T24 series of devices.

Using this tool may help in detecting noisy areas and allow you to decide on which channels you may want to

use.

The above charts show the traffic from a Wi-Fi network and it can be seen to be operating over channels 6 to 9

and it would be best (though not essential) to avoid using these channels.

Mantracourt Electronics Limited T24-RA User Manual

Data Provider Monitor

T24 acquisition devices normally operate in low power mode and periodically transmit Data Provider

packets

This page shows all detected Data Provider packets which may be useful for checking that a device is

operational.

NOTE: When the toolkit connects to a device to enable configuration it will usually inhibit the transmission of Data Provider packets.

The Start Logging button will ask for a filename and proceed to log the received data to a CSV file in the

following format:

Data Tag, Elasped mS, Value

The View Last Log button will launch the application associated with CSV files and open the last logged file.

Information

Once successfully paired to a device this page is displayed.

This page shows you information about the connected device.

Items you can change:

Name

You can enter a short description which may help you recognise this device in the future.

Mantracourt Electronics Limited T24-RA User Manual

Battery and Radio Levels

Here you can see the voltage of the battery and the radio signal levels at the base station and the remote

acquisition module. This simple view gives an LQI value which stands for Link Quality Indicator. This value will

range from 0 to 100 and within this band you should still achieve communications. As the level drops towards

zero communications may become intermittent but still achievable.

You can set the level at which the acquisition module reports a low battery.

If the battery voltage is below the Low Battery Level the bar will be coloured orange.

Items you can change:

Low Battery Level

Click this item to set the battery low level.

Clicking the Advanced button will give more detailed information on the RSSI and CV levels of the received

radio packets.
