1. Introduction LAS-604V3 is a temperature sensor that utilizes LoRaWAN to periodically report temperature. The temperature measurement is through PT100 probe. For forcing various requests of demand, LAS-604V3 supports two operation modes, mode A and mode B. Mode A is hourly report that temperature is reported or recorded every hour. Mode B supports temperature measurement every 30 seconds, 1 minute or 2 minutes, depending on setting.
2. Installation The first step to start to use LAS-604V3 is installing battery. LAS-604V3 can be opened by simultaneously holding and pressing two places in red circle of following figure. A battery holder is inside LAS-604V3, as Figure 2. The supply voltage of battery is 3V.
There is a wakeup button, SW1, which is used to wakeup LAS-604V3 when it enters deep sleep mode. Figure 3 Wakeup Button There is a jumper inside LAS-604V3 for selecting operation mode of LAS-604V3. Figure 4 is an example which sets LAS-604V3 to Mode B.
3. Device Setup Device Activation: First step is created a node on LoRaWAN Network Server. The Device EUI, Application Session Key, and Network Session Key will get from product supplier. Application must set to LAS-602/4 and Activation and LoRaWAN Class should be set to ABP and Class A separately. Note: Due to LAS-602/4 sending periodically report at each clock, the downlink window is recommended to set to RX2 for preventing from data collision.

Temperature Report in Platform: The temperature report is under application of LAS-602/4, as following figure shows.
4. Report and Data Format 4.1. Mode A LAS-604V3 reports temperature and alarm through LoRaWAN’s uplink. By default, LAS-604V3 will send a temperature report every hours. In addition to temperature report, LAS-604V3 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.
4.1.1. Temperature Report Temperature report is sent by LAS-604V3 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 Reserved (1 Byte) Temperature (1 Byte) Temperature ... (2 Bytes) (2 Bytes) Battery: The most significant bit indicates low voltage. The least significant 7 bits is battery voltage multiplying 10.
FPort: 201 Setting TX Period Detection Period Lowest Allowable Highest Allowable Command Temp. (2 Bytes) Temp. (2 Bytes) (1 Byte) (1 Byte) TX Period: Unsigned integer presents period of temperature report in hour, can be 1 to 24. Detection Period: Unsigned integer presents period of temperature detection in minute, can be 1 to 30. Temperature: Signed integer, big-endian, multiplies 10.
4.2. Mode B There is one uplink data type of LAS-604V3 for reporting temperature records and 3 downlink data type for remote settings whose are manually offset setting, interval time/record period, and single mode (Mode 1) setup. The formats of these data types are described at following section. 4.2.1. Temperature Report (Uplink) Temperature report is sent by LAS-604V3 at every predefined period. The period can be changed by downlink command.
4.2.2. Remote Setting Command (Downlink) Remote setting command is sent by server to LAS-604V3 for changing offset by manually, interval time and record period, and single mode activate. Once LAS-604V3 getting a downlink command, it should send back a status report for confirmation. In Server downlink page, selecting the specific device and port 15 for setting.
5. Firmware Upgrade LAS-604V3’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-604V3. 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-604V3.
