Introduction
1. INTRODUCTION
This manual is written to help the user to get familiar with the installation and operation of LM Pro RF.
It is designed for reliable and convenient recording of process parameters in production, Research and
Quality control applications. This device can sense the Temperature and Humidity, displaying them on
LCD display ae well as sending these data via RF signal to Moderator device for monitoring on
gtekNetTM.

1.2 LM PRO RF DESCRIPTION
The LM Pro RF series of wireless data logger is a new RF based data logger measuring temperature
and % RH. These data loggers are very useful in monitoring data across large facilities where wiring is
difficult. Since no wiring is required, deployment is very quick and easy. Data are sent by each device
directly to the centralized moderator (repeater) device and from there to gtekNetTM software over
ethernet port. These data can be accessed from any network connected device using standard web
browser.
The data logger consists of RF radio transmitter and receiver operating at 869.88 MHz (SRD License
Free: EU Version) frequency. These data loggers form a star network with its moderator. The
moderator is connected to the client-server based gtekNetTM software through ethernet. A new data
logger when it is inthe range of the central node –moderator, gets easily connected to the gtekNetTM.
Each device transmits its data to the moderator and is captured in gtekNetTM. Any parameter of the
data logger when set / changed from gtekNetTM, first goes to the moderator and then to the device.
These data loggers have an internal memory of 32000 data sets. In the event of communication failure
between moderator and device or moderator and gtekNetTM, after reconnection, all the missed data
will be synchronized by gtekNetTM automatically. This ensures that no data is missed.

Introduction
1.4.1 Status LEDs
There are two status LEDs available on LM Pro RF device for the indication of device status. The
meaning of both the LEDs are described as below:
HBT
Heartbeat LED will be flickered at every 5 minutes for updating time of data,
after that it will be OFF till next interval comes.
STR
Storage LED will be flickered with Heartbeat LED, if Batch is ON at every 5
minutes. Otherwise, Storage LED will remain in OFF state if Batch is OFF.
1.4.2 Display LCD
The LCD display is 3 ½ digit display shows the Temperature and %RH value with its units, alarm
high/low indication and Recording indication as per the operation of the device. The LCD display parts
are shown in figure 2.

3.2 LM PRO RF OPERATION
•Once the Setup is done as per the schematic diagram, LM Pro RF show Room Temperature
and %RH on display continues Scrolling every 5 minutes.
•The HBT Led will flicker at 5 minutes time interval and display will be updated.
•The STR led will flicker with HBT Led at 5 minutes time interval, if Batch is running.
Otherwise STR led will remain in OFF state.
•When the Batch is running, recording indication is shown on LCD display as section3.4.1
LCD display.
•If alarm condition is created in any channel (Temperature or RH), Alarm high/low
indication will be shown on display as per section3.4.1 LCD display. Note that the display
will be blinked in Alarm condition.
•The Temperature and %RH data is also sent to the Moderator via RF signal and with the
help of Moderator the data will be observed on GtekNet Application.
•We can download the data in csv, pdf format using GtekNet application.
