1Straightpoint SW-SB USER MANUAL

Introduction / Overview

The SW-SB is an active repeater which will allow the T24 range of modules to span around obstacles

or increase range or coverage.

The connectivity module provides a battery holder for a pair of alkaline ‘D’ cells and has regulator circuitry

for an external power supply. The batteries can also be used to provide power in case of external supply

failure. The case is environmentally sealed to IP65.

The repeater will allow messages to be repeated once which can effectively double the radio range.

Adding more repeaters will not increase range but can increase coverage.

Power Options

The SW-SB can operate permanently powered or can operate from on-board batteries.

Permanently Powered

This is the simplest way to operate the repeater. With a permanent supply you do not need to worry about

the repeater sleeping or waking. You can optionally choose whether the repeater always wakes sleeping

modules and then you could utilise the powering up of the repeater to wakeup those modules outside the

normal radio range.

Battery Powered

In low power battery mode the repeater wakes from sleep when other modules are woken and will remain

awake until it stops receiving Stay Awake messages. This will work transparently with most SP wireless

instrumentation. Please note that a SW-C handheld would require radio firmware version 2.01 or above to be

able to wake a repeater when powered on.

You just need to decide on the Sleep Delay for a battery powered repeater. This causes the repeater to

enter sleep mode if it does not receive stay awake messages within the Sleep Delay time.

Stay awake messages are transmitted by handhelds, analog output modules and PC software etc so that when

those items are turned off or disabled all other T24 modules will sleep when their Sleep Delay time elapses.

Connecting Power

Power can be supplied by fitting 2 X ‘D’ cell alkaline 1.5 Volt batteries or the module can be supplied from

an external 5V to 18V DC source.

3Straightpoint SW-SB USER MANUAL

In both cases you need to fit the JP1 power jumper to supply power to the acquisition module.

When powered from the external DC source the LED will illuminate.

If internal batteries are fitted when external power is applied the batteries will be utilized if external power

is lost.

Getting Started

Use the T24 Toolkit to ensure that the repeater radio channel matches the rest of the T24 modules. You will

then need to decide whether the repeater is battery powered or permanently externally powered and

whether it should always wake other sleeping modules when it is powered up and awake.

Considerations

Each repeater can effectively double the amount of traffic transmitted. Be careful not to introduce

too many repeaters that are within range of each other as there may be un-necessary duplication of

radio traffic. Carefully plan the layout of radio modules to minimise this.

Using the Data Provider monitor in the T24 Toolkit can show the amount of traffic. The T24 Toolkit on

a laptop or netbook is ideal for checking installations as it is mobile so traffic can be monitored at

different points in the installation.



A repeater will not repeat a packet that has already been repeated. Hence there is only one

extra ‘hop’ introduced and a maximum range increase to 2X.



When waking remote modules separated by a repeater and that repeater is asleep it may take twice

as long to wake a module as when no repeater is involved.



If the repeater is to be battery powered use the same Sleep Delay as is suitable for the

acquisition modules in the system.



You cannot pair to a module through a repeater. Using the T24 Toolkit it may be possible to

configure module through a repeater by connecting without pairing. The results will vary depending

on the number of repeaters and amount of radio traffic. In some cases it may be necessary to power

down repeaters when configuring modules.



Most data consumer modules and software issue a broadcast wake when turned on or activated and

this will also wake a sleeping repeater which will then proceed to wake those modules within its

range. But some modules only wake specific single target modules such as the T24-HS handheld

module and the T24-AO1 analog output module. For these modules to wake the repeater they must be

fitted with at least v2.1 version radio modules. This only affects repeaters with a SleepDelay set.

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 SW-USBBSE base station to allow your computer to

communicate with SP 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.

Base Station

If you have a USB version of the base station (SW-USBBSE) 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.

T24 Toolkit

The T24 Toolkit provides a means of simple configuration of the SW-SB along with useful tools to

aid integration.

Run the T24 Toolkit software application.

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.

Straightpoint SW-SB USER MANUAL 6

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.

Pairing Procedure

Remove power from the SW-SB module.

Click the Pair button on the toolkit.

You now have 10 seconds to re-apply power to the SW-SB module.

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

If the pairing fails try again.

NOTE: The act of Pairing with the toolkit will not change the radio configuration settings of the

connected device. The settings will only change if you change them yourself within the toolkit.

7Straightpoint SW-SB 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.
