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.

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.

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.

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.
