1. OVERVIEW

The WIRELESS-T24-HA is an advanced handheld display. This allows wireless remote viewing of multiple inputs

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

The WIRELESS-T24-HA also performs the function of optionally waking the remote modules when it is

turned on and sending them to deep sleep mode when it is turned off.

The handheld can operate in two modes. The operation of the buttons and the automatic sleep/wake functions

are dependent on these modes.

Result Mode

This is the default mode in which multiple transmitter modules are used to create a result which is displayed.

Currently the WIRELESS-T24-HA only provides a sum of the remote modules but this function may be added to

in future versions. Although the handheld usually shows the result (sum) there is an option of viewing the discrete

values that make up the result.

Item Mode

In this mode each transmitter module is treated as a separate reading and the handheld is used to cycle through

the available items and the value of each can be viewed.

1.1. Order Codes

WIRELESS-T24-HA

Handheld display for use with multiple transmitters and with advanced functionality.

1.2. Connections

1.2.1. Power

The handheld module is powered by two alkaline AA batteries.

For battery information please refer to Appendix D –Battery Selection

Due to the higher voltage requirements of this module NiMh and NiCad batteries are not recommended.

1.3. Operation

The handheld can operate in two modes and the button operation is dependent on these modes.

1.3.1. Item Mode

Up to 12 individual modules can be connected to and the user can step through each one in sequence.

If DoSleepWake is set then the handheld will wake transmitters when turned on and send them all to sleep again

when turned off. When the handheld wakes modules this is achieved through the transmission of a broadcast wake.

i.e. all modules on the same channel and with the same group key will wake.

1.3.1.1. Keys

Sleep key - Send the currently selected module to sleep.

Wake Key - Will attempt to wake the currently selected module.

T 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.

Next Key - Step to the next module. A brief prompt will be displayed before the value is shown.

i.e. ‘Input 1’, ‘Input 2’ etc. Also see Prompts

F1 If motion detection is activated then the reading must be steady to enable this key. Pressing this key

with an unstable reading will do nothing.

Function Key - This transmits a Data Provider packet marked with a Data Tag held in F1DataTag

and can also contain data as defined by F1Data. This can be used to trigger external actions such as

a printout.

Power Key - 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.

Up to 12 individual modules can be summed and the result displayed.

If DoSleepWake is set then the handheld will wake all modules when turned on and send them to sleep again

when turned off. When the handheld wakes modules this is achieved through the transmission of a broadcast

wake. i.e. all modules on the same channel and with the same group key will wake.

In this mode there is an option of retrieving a system zero value from an external source. This is activated by

supplying the Data Tag to the ExtZeroDataTag parameter. When activated the value supplied by the Data

Provider packet marked with this tag will be used as the system zero and will be subtracted from the sum of all

contributing inputs.

Usually in this mode only the result is displayed (sum) but holding the Next key for a configurable number of

seconds will activate the ability to step through each contributing input using the Next key.

1.3.1.2. Keys when viewing Result

Sleep Key - No effect.

Wake Key - Will attempt to wake any sleeping modules.

This uses a broadcast wake so any modules on the same channel with the same group key will

wake.

Tare Key - Toggle between displaying gross sum or tared sum.

Next Key - No effect unless held for a number of seconds to activate individual item view.

This can be disabled. See Allow Next Key

Newer versions also allow customised prompt messages to replace the default ‘Input 1’, ‘Input

2’ etc. See Prompts

Function Key - If motion detection is activated then the reading must be steady to enable

this key. Pressing this key with an unstable reading will do nothing.

This transmits a Data Provider packet marked with a Data Tag held in F1 DataTag and can

also contain data as defined by F1 Data ( See Mode and Communications later ). This can

be used to trigger external actions such as a printout or a relay operation. This would require

suitable relay or printer WIRELESS-T24 modules.

Power Key - Toggles between on and off. Hold for 2 seconds to activate.

1.3.1.3. Keys when viewing an individual item

Sleep Key - No effect.

Wake Key - Will attempt to wake the currently selected module.

TTare Key - If sum was currently tared then this key will toggle between displaying gross or tared

value of current module. If sum view was displaying gross then this key has no effect.

If an external system zero is used then only gross values actually supplied to the

handheld can be displayed.

Next Key - Selects next input item to view.

F1 Function Key - If motion detection ( See settings in Display Format later ) is activated then the reading

must be steady to enable this key. Pressing this key with an unstable reading will do nothing.

This transmits a Data Provider packet marked with a Data Tag held in

F1DataTag and can also contain data as defined by F1Data. This can be used

to trigger external actions such as a printout.

Power Key - Toggles between on and off. Hold for 2 seconds to activate.

1.4.1. All Modes

1.4.1.1. Indicators

GThe display is showing Gross weight.

NET The display is showing Net weight.

SIG LOW The radio signal from the transmitter module is low. The module 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.

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 transmitter module has an error that the handheld does not recognise.

REMOTE BATT LOW

The battery or supply to the transmitter module is low.

Errors

Displayed on handheld LCD.

Error 1

The transmitter module has a strain gauge input and is in shunt calibration

mode. An external module has placed the transmitter module in Shunt

Calibration mode so rather than display a misleading reading this error is

displayed instead.

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

Error 2

Input integrity error. The transmitter 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 transmitter modules support this error such as the WIRELESS-T24-

SA.

Overload

The overload limit set by the user has been exceeded.

{Display Flashing}

The motion detection has been enabled and the reading is deemed in motion

or unstable.

Other Functions

System Zero

If enabled, holding the Tare key for a number of seconds will perform a system

zero.

Pairing

2. CONFIGURATION

The WIRELESS-T24 Toolkit provides a means of simple configuration of the handheld module along with useful

tools to aid integration.

Launch the WIRELESS-T24 Toolkit software application and pair to this module to enable the connection to the

Toolkit to allow configuration to take place. See Common Toolkit Pages - Home

2.1. Mode and Communications

This page allows you to set the operational mode of the module and configure which external transmitter

modules the handheld will connect to.

Items you can change:

Operational Select in which mode the handheld will operate.

Mode

Result Mode

Up to 12 individual transmitter modules can be summed and displayed. Optionally the

operator can view the individual module values (See Allow Next Key).

Item Mode

Up to 12 individual modules can be displayed and the user can step through each one in

sequence.

MA-WIRELESS-T24-HA_EN.docx

Allow Next Key Only used in Result Mode. Usually in Result mode only the result (sum) of the individual

modules is shown. By entering a non-zero value here this will define the number of seconds

that the Next key needs to be held down to enable individual item values to be viewed.

Once available the Next key will cycle between all the individual values and the result. This

will remain available until the handheld is powered off.

Each time the Next key is pressed the display will show a brief message indicating what will

be displayed; Input 1, Input 2, Result etc. From firmware version 1.2 onwards the handheld

allow customised prompt messages. See Prompts

F1 Data Tag The F1 key can be used to trigger other modules such as a WIRELESS-T24-SO module to

provide

printer services etc. This key will generate a Data Provider message which other modules

can use.

Set this value to non zero to enable this function and to define the Data Tag that will

identify the message sent.

The content of the message is defined by the F1 Data parameter.

If motion detection is configured then this key will have no effect while

the reading is not steady.

F1 Data

Define what data is carried in the Data Provider message when the F1 key is pressed.

Select Always Gross to transmit the gross value regardless of whether the Tare key has

been pressed.

Select As Displayed to transmit either the gross or net value depending on the currently

displayed data.

Remote Data Tags and IDs

Data Tag

Enter the Data Tag of the message to use for the specified input item.

Enter the ID of the module used to supply the specified input item.

This is only necessary for Item Mode where individual items are to be

woken using the Wake key as opposed to letting the handheld wake all

modules.

If you are not using Item mode then you are not required to enter the ID although it will be

filled in automatically if you pair to a module to retrieve its settings.

Click this then perform pairing on a remote transmitter to automatically provide the ID and

Data Tag. Usually pairing is activated by removing and replacing the power supply on the

remote transmitter. You must perform pairing within 5 seconds of clicking the button.

Click this to reset the Data Tag and ID to zero (disabling the input item).

Set Prompts

For modules with a firmware revision of 1.2 and newer this button will be visible. This

displays a page where the message labels shown before switching between channels can be

set by the user.

2.2. Prompts

Here you can adjust the messages shown when switching between input channels in Item Mode..

Items you can change:

Prompts 1 to 12 These prompts are briefly shown when switching between inputs. They default to

‘input 1’, ‘input 2’ etc

Leave the prompt blank to display the Data Tag of the module supplying data to

the current item.

The displayed prompts are limited to 8 characters and be aware that the 7

segment LCD display is very limited in how it can represent letters. Some

letters cannot be displayed. These include K, M, W, X

Prompt for result Enter the prompt to display before the total result is displayed.

2.3. 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-HA 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 transmitter module. If this falls within ± of this value then the

display will be altered so this reads zero.

Example: A strain gauge transmitter module (WIRELESS-T24-SA) is calibrated in

kg and measures the weight of boxes on a platform. The weight of the platform itself

has been removed using system zero on the transmitter 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.
