(% style="color:blue" %)** Wiring:**

55

56

~1. WSC2-LB and sensors all powered by solar power via MPPT

57

58

2. WSC2-LB and sensors connect to each other via RS485/Modbus.

59

60

3. WSC2-LB read value from each sensor and send uplink via LoRaWAN

61

62

63

WSC2-LB is shipped with a RS485 converter board, for the easy connection to different sensors and WSC2-LB. Below is a connection photo:

(% style="color:red" %)**Notice 1:**

70

71

* All weather sensors and WSC2-LB are powered by MPPT solar recharge controller. MPPT is connected to solar panel and storage battery.

72

* WSC2-LB has an extra 1000mAh back up battery. So it can work even solar panel and storage battery Fails.

73

* Weather sensors won't work if solar panel and storage battery fails.

74

75

(% style="color:red" %)**Notice 2:**

76

77

Due to shipment and importation limitation, user is better to purchase below parts locally:

* Solar Panel

* Storage Battery

* MPPT Solar Recharger

82

* Mounting Kit includes pole and mast assembly. Each weather sensor has it's own mounting assembly, user can check the sensor section in this manual.

83

* Cabinet.

85

== 2.2 How it works? ==

(((

Each WSC2-LB is shipped with a worldwide unique set of OTAA keys. To use WSC2-LB in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After finish installation as above. Create WSC2-LB in your LoRaWAN server and Power on WSC2-LB , it can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the WSC2-LB device in TTN V3:

115

116

117

(% style="color:blue" %)**Step 1**(%%): Create a device in TTN V3 with the OTAA keys from WSC2-LB.

161

162

Uplink payloads include two types: Valid Sensor Value and other status / control command.

163

164

* Valid Sensor Value: Use FPORT=2

* Other control command: Use FPORT other than 2.

166

170

Uplink the device configures with FPORT=5. Once WSC2-LB Joined the network, it will uplink this message to the server. After first uplink, WSC2-LB will uplink Device Status every 12 hours

(((

User can also use downlink command**(0x2301)** to ask WSC2-LB to resend this uplink
