T24-TA [Temperature Acquisition Pt100]

Overview
The remote acquisition module requires an external platinum temperature sensor (Pt100). The module
measures the temperature and periodically transmits it. Between transmissions the device is optionally in a
power saving sleep mode to conserve batteries.
Various devices are available that utilise the transmitted data and include handheld
displays etc
Communications
To configure the device you will use the Read and Write mechanisms described in the Data Packet Structures
section to read and write parameters and execute commands.

12 Set or read the output power level. (0-100%)
10 Set or read a user defined name. (11 characters)
51 Read the model number of the device.
16 Set or read the interval in milliseconds that a sleeping
device will wake to request a full wake from the base
station. (default 3000)

69 The voltage measured on the battery.
110 Set or read the battery voltage at which the low
battery flag will be set in all received packets and in
the Status parameter).
75 Defines power save mode.
0 = Awake all the time and transmit at TxInterval.
1 = Sleep. Wake at TXInterval, acquire value, transmit
value, sleep.
76 Time Interval between Transmissions. Set mS
78 Set or read the SampleTime in milliseconds for
acquiring a reading at each TxInterval interval. The
larger the SampleTime the more accurate the reading
but at the expense of battery life. (Default 5)
77 Time period before switching to low power sleep mode
if no StayAwake command or trigger received.
Setting to zero disables.
119 Set or read the 2 byte Data Tag that is used when
transmitting the weight in a Data Provider Packet.
Note that default value is set to last 2 bytes of ID.
