UserName
User friendly name for the sensor
29 characters 0-9, A-z, and
special characters (space and “.”)
SensorReadPeriod
Selects the transmission rate (see selectable transmission
rates on page 4)
11 transmission rate options
ResetMessageCounters
Resets MessageAttempts, MessagePacketRetries, and
MessageFailures to 0.
InputSend
Enabling (set to 1) configures sensor to transmit when
scheduled and when the input state changes.
0 to 1
FactoryReset
Resets all programmable settings except UserName and
Network Key.
Only occurs if ReadCounter is
below 20.
Linked
Writing a Controller’s NetKey to the Linked Parameter has
it join the Controller’s network. The unlinked NetKey is
FFFFFFFF.
Must write an 8 digit Hexadecimal
number (0-9 & A-F).
CalibrationKey
Writing the appropriate command will calibrate to RTD
Input to 100 Ohms. Details available in the calibration
section.
BATTERY LIFE
The RTD Input spends most of its time in sleep mode; it wakes up to take readings, send data and see if any packets are
in the queue to be received. Battery life can be maximized by reading/sending the sensor data as infrequently as possible.
Battery life is highly variable on a number of parameters.
1. How often data is read/sent.
2. Extreme temperatures reduce the useful life of the battery.
3. If the sensor is sending data through a repeater, battery life will be reduced because the sensor has to wait longer
for the acknowledgment.
4. If the sensor has to reconnect to the controller frequently, battery life will be reduced. This happens when the
signal is low or there is interference.
5. Channel hopping
6. The battery chemistry will affect the performance. Lithium batteries will provide substantially better performance
especially in cold environments.
Expected battery life in normal conditions at a 1 minute transmission rate is 2+ years.
INLINE POWER (Optional with MOQ)
A RTD Input with inline power and battery backup is available for special order. A power supply capable of providing 4 to
16VDC with a right angle 2.5mm barrel connector is suggested. The battery backup is not charged by the presence of
inline power.
RTD INPUT CALIBRATION
Each input is factory calibrated to ±0.01% accuracy at 21°C. The Callendar-Van Dusen equation and calibration
performed on each reading. It has an accuracy of ± 0.1° across probes temperature (with MeshNet RTD Input at 21°C
).
6
The MeshNet RTD Input may be recalibrated at temperatures significantly different than 21°C. Contact
