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.

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. Loosen two screws. 1. Power Switch 2. Battery Connector 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. Hanging Hole Magnet Figure 4 Mount of LAS-603 kiwitec Confidential Documentation 2 3. Report and Data Format LAS-603 reports temperature and alarm through LoRaWANs 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.

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. FPort: 200 Temperature Report Battery

Setting of Gateway Gateways 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 kiwitec Confidential Documentation 6 Temperature Report The temperature report is under application of LAS603, as following figure shows. Figure 8 LAS-603 Report kiwitec Confidential Documentation 7 5. Firmware Upgrade LAS-603s 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. If the upgrade is going well as following figure, the upgrade process is success and the new firmware is programmed to LAS-603.
