T24-HA [Handheld Reader Advanced]

Overview
The T24-HS captures Data Provider data from multiple devices and displays it. The T24-HS also performs the
function of optionally waking the remote device when it is turned on and sending it to deep sleep mode when it is
turned off. If no buttons are pressed on the T24-HS it will turn off after 5 minutes.
The handheld can operate in two modes. The operation of the buttons and the automatic sleep/wake functions
are dependant on these modes.
To attach devices to the handheld we must first ensure that the appropriate devices are transmitting their values
at a suitable rate such as the default of 3 per second. Then we can tell the handheld which devices we want to
communicate with by either automatic pairing or manual setting of the parameters.
Automatic Pairing
The handheld supports pairing replace an existing device. i.e. initially the handheld would be configured using
manual configuration.
If then a T24-SA device required replacing and this was item 3 in the handheld we would follow the following
procedure:
First select this device even though the display may show ------ because of no communications. (In Result
mode you would have to hold the Next key to enable selection of individual devices.)
Next turn off the handheld 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 T24-SA within 10 seconds.
If unsuccessful the display will show failed. If successful the Data Tag and ID of the new device will have
been configured within the handheld.
Depending on how the replacement device was configured it may be necessary to reapply the system zero.
Manual Configuration
Use the parameters ValueDataTag1 through to ValueDataTag12 and ValueID1 through to ValueID12 and enter
the Data Tags and IDs of the devices to connect to.
For example, to sum two T24-SA devices whose Ids are FFF123 and FFFABC.
The default data tags for these devices would be F123 and FABC so we would set the following:
ValueDataTag1=F123
ValueID1=FFF123
ValueDataTag2=FABC
ValueID2=FFFABC
We would ensure that the other unused ValueDataTagx and ValueIDx parameters were set to zero.
Available Modes
Item Mode
Opmode = 0.
Up to 12 individual devices can be connected to and the user can step through each one in sequence.
If DoSleepWake is set then the handheld will wake all configured devices when turned on and send them all to
sleep again when turned off. NOTE: When the handheld wakes devices this achieved through the transmission of a
broadcast wake. i.e. all devices on the same channel and with the same encryption key will wake.
Key Operation
Key Operation
Sleep Send the currently selected device to sleep.
Wake Will attempt to wake the currently selected device.
Tare Toggle between
Next Step to the next device.
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.
This transmits a Data Provider packet marked with a Data Tag held in F1DataTag and can also
contain data as defined by F1Data.
Power Toggles between on and off. Hold for 2 seconds to activate.
