1. INTRODUCTION / OVERVIEW

The WIRELESS-T24-HS is a simple handheld display. This allows wireless remote viewing of various remote

inputs such as strain gauge or voltage etc using 2.4GHz radio.

The remote acquisition module measures its input value (strain gauge, voltage, current etc) and periodically

transmits it.

The WIRELESS-T24-HS captures this data and displays it. The WIRELESS-T24-HS also performs the

function of waking the acquisition module when it is turned on and sending it to deep sleep mode when it is

turned off. The acquisition module will automatically enter deep sleep mode after 1 minute (default) if a

WIRELESS-T24-HS is not present.

If no buttons are pressed on the WIRELESS-T24-HS it too will turn off after 5 minutes.

1.1. Quick Start

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

You will require 2 X AA alkaline batteries for the handheld and a 3 Volt dc supply for the acquisition module

which may also be a pair of AA batteries.

1.1.1. Connecting Power

1.1.1.1. WIRELESS-T24-HS

Remove the two screws on the rear battery compartment. Insert two alkaline AA batteries. Refit the battery

compartment cover. The handheld device is now switched on so should be turned off until the acquisition

module is ready. To turn off just hold down the power key until the display shows BUSY then release it.

1.1.1.2. Acquisition Module

See the acquisition module manual.

1.1.2. Pairing

We will use automatic pairing to prove the connectivity and operation. Pairing sets the communications

configuration parameters to allow the two devices to communicate. We do not need a PC or laptop or any

configuration software to perform basic pairing.

−Ensure that acquisition module is not powered.

−We need to turn on the WIRELESS-T24-HS in pairing mode. To do this we start with it turned off, then

press and hold the power key then press and hold the Tare key. Now both keys are held down until

PAIRING is seen on the display. The keys can now be released.

−Now apply power to the acquisition module within 10 seconds.

−If successful the WIRELESS-T24-HS will pair to the acquisition module and the display will show a

numeric value. (Or Error 2 if the input integrity has failed. For example if the acquisition module is a

T24-SA and the strain gauge is not connected).

If the display shows Failed or

- - - - - - - -

then the pairing failed.

Once successful the WIRELESS-T24-HS will be linked to the acquisition module and will send it to sleep when

the handheld is turned off and wake it when the handheld is turned on.

Remember that from this point onwards to turn the handheld on you just need to press and hold the power key

as the pairing mode is no longer required.

MA-WIRELESS-T24-HS_EN Page 3 on 21 Rev: 09/05/2011

1.1.3. WIRELESS-T24-HS Operation

1.1.1.3. Keys

Press and hold the power key until the display shows BUSY then release the key.

Can also be used, by giving a quick press, to reset the Auto-Sleep delay.

Press the TARE key. This will toggle between gross and zeroed net mode. I.e. If the

display shows gross then pressing the key will zero the display. Pressing the key when

in net mode will return the display to gross mode. The Gross and Net modes are

indicated as described below. Gross and Net are retained through power off.

1.1.1.4. Modes

Pairing

When you want to use the WIRELESS-T24-HS with a different acquisition module you

use pairing. (Ensure that the acquisition module is unpowered for at least 10 seconds.)

Press and hold the Power key then while still holding down the power key press and

hold the Tare key.

Hold both keys until you see PAIRING on the display.

Release the keys and apply power to the acquisition module.

NOTE: When pairing, the channel and encryption key settings on the acquisition module

are changed to match those on the WIRELESS-T24-HS.

1.1.1.5. Indicators

G The display is showing Gross weight.

NET The display is showing Net weight.

SIG LOW

The radio signal from the acquisition module is low. The device is still functioning but the

limit of the range may be near. Communications may start to deteriorate when this

indicator is visible. Until

- - - - - - - -

is displayed the communications is still OK and the display

can be relied on for accuracy.

Note: Even with a degraded signal the display value will always be correct.

BATT LOW The batteries in the handheld are low and need to be replaced.

REMOTE ERROR The acquisition module has an error that the handheld does not recognise.

REMOTE BATT LOW The battery or supply to the acquisition module is low.

1.1.1.6. Errors

Displayed on handheld LCD.

Error 1

The acquisition module has a strain gauge input and is in shunt cal mode. An external

device has placed the acquisition module in Shunt Calibration mode so rather than

display a misleading reading this error is displayed instead.

Modules such as the T24-SA support this error type.

Error 2

Input integrity error. The acquisition module has found a problem with the input. There

may be open or short circuits. Rather than display a misleading reading this error is

displayed instead.

Only certain acquisition modules support this error such as the T24-SA.

Overload A user settable value which when exceeded causes this message to be displayed.

2. CONFIGURATION

This section explains how to install software and connect the required devices together. 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.

2.1. Installation

2.1.1. 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.

2.1.2. 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.

MA-WIRELESS-T24-HS_EN Page 5 on 21 Rev: 09/05/2011

2.2. T24 Toolkit

The T24 Toolkit provides a means of simple configuration of the WIRELESS-T24-HS handheld and associated

acquisition module along with useful tools to aid integration. Calibration of the acquisition module is also

provided.

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-SA strain gauge acquisition module is connected.

2.2.1. 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.

MA-WIRELESS-T24-HS_EN Page 6 on 21 Rev: 09/05/2011

2.2.2. 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 handheld 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.

MA-WIRELESS-T24-HS_EN Page 7 on 21 Rev: 09/05/2011

2.2.3. 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.

MA-WIRELESS-T24-HS_EN Page 8 on 21 Rev: 09/05/2011

2.2.4. 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:

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

2.2.5. 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.

MA-WIRELESS-T24-HS_EN Page 10 on 21 Rev: 09/05/2011

2.2.6. Zero Settings

Here you can adjust settings that affect the display of zero.

Items you can change:

−Power On Auto Zero : Here you can determine whether the WIRELESS-T24-HS performs automatic

zero when it is powered on. Enter zero to disable this function. If you enter a non-zero value then when the

handheld is first turned on it checks the value read from the acquisition module. If this falls within ± of this

value then the display will be altered so this reads zero. Example: A strain gauge acquisition module (T24-SA)

is calibrated in Kgs and measures the weight of boxes on a platform. The weight of the platform itself has been

removed using system zero on the acquisition module. Sometimes there is debris on the platform which you

do not want to see when viewing the weight of boxes that will be placed on the platform later.The minimum

weight of a box is 5 Kg so you could set the Power On Auto Zero to 2 Kg. When you turn on the handheld, if

the weight on the platform is between -2 and +2Kg then the handheld will tare this weight off and so read zero.

−Zero Indication Band : Using this setting you can mask tiny changes in input after you press the Tare

button. Entering zero will disable this function. Entering a non-zero value will provide a band within which the

display will always read zero. Once the reading exceeds this value the real weight will be displayed as no

taring is taking place. Example: You are adding boxes to a platform and you press tare between adding each

one so you can see the weight of each box. Without this setting activated each time you tare the display will be

around zero but not exactly zero (By setting the display resolution you may hide this difference) by setting a

small value here such as 0.2Kg the display will show a stable zero while actual weight is fluctuating less than

± 0.2Kg.
