1. Introduction
LAS-603 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. LAS-603 can also
send an abnormal temperature alarm once environment temperature is out of predefined allowable range.
The periodically report will be sent on each clock. Therefore, LAS-603 will retrieve date time from server at
boot up. In addition, there are 3 magnets at bottom side of LAS-603 for easily mounting on metal surface.

2. Installation
To start to use LAS-603, the battery should be installed well and power switch should be ON position. Please
loosen two screws at bottom of LAS-603 and open the back cover, as Figure 3. Then make sure the battery is
connected to connector and power switch is ON position.
Figure 3 Installation of LAS-603
LAS-603 has two mounting methods. As shown on Figure 4, magnet can be used to mount on metal surface
and hanging hole can be used to hook on any surface having object.

3. Report and Data Format
LAS-603 reports temperature and alarm through LoRaWAN’s uplink. By default, LAS-603 will send a
temperature report every 4 hours and the report contains 4 temperature records at each clock. In another
words, LAS-603 will read temperature every hour and keep in memory. Then, LAS-603 sends the
temperatures readings in memory at predefined period, default is 4 hours.
In addition to temperature report, LAS-603 will read temperature every 5 minutes by default and compare
read value with allowable temperature range. If read temperature is out of allowable temperature range, an
alarm will be sent. Besides, the allowable temperature range can be set by downlink command.
Except temperature and status report, a LoRaWAN MAC command, DeviceTimeReq, is sent from LAS-603
to server for time synchronization. Figure 5 depicts the entire sequence from power on.

3.1. Data Format
There are 3 uplink will be sent by LAS-603, temperate report, status report and temperature alarm. The
format of these 3 reports are described at following.
3.1.1. Temperature Report
Temperature report is sent by LAS-603 at every predefined period. The period can be changed by downlink
command. The length of temperature report depends on how many temperature records in a single report.
3.1.2. Status Report
Status report is sent by LAS-603 at power-on and when LAS-603 getting downlink command.
3.1.3. Temperature Alarm
Temperature alarm is sent by Las-603 when the read temperature is out of allowable range.

4. Example
This section gives an example of setting LAS-603, gateway and Kiwi-tec’s LoRaWAN Network server.
Setting of Gateway
Gateway’s receiving frequencies must be same as LAS-603. And, the address of packet forwarder must be set
correctly to LoRaWAN network server.
Figure 6 Gateway Setting
Setting of LoRaWAN Network Server
Final step is create a node on network server as Figure 7 shows. The Device EUI, Application EUI, and
Application Key is get from above operation. Application must set to LAS603 and Activation and LoRaWAN
Class should be set to ABP and Class A separately.
Note: Due to LAS-603 sending periodically report at each clock, the downlink window is recommended to
set to RX2 for preventing from data collision.
Figure 7 Create Node on Network Server

Temperature Report
The temperature report is under application of LAS603, as following figure shows.

5. Firmware Upgrade
LAS-603’s firmware can be upgraded through UART by using TLM922S Flash Tool. Please make sure the COM
port number is the interface connected between PC and LAS-603.
The first step is setting COM port number and click "Get Ver+Cfg" button. If the version name does not appear,
there might be problems on connection between PC and LAS-603.
Figure 9 Setup COM Port and Connection
Next step is clicking "Select Image" to choose firmware file and clicking "Upload" to start the upgrade
procedure.
Figure 10 Select Firmware and Upgrade
If the upgrade is going well as following figure, the upgrade process is success and the new firmware is
programmed to LAS-603.
