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

51

52

~1. WSC1-L and sensors all powered by solar power via MPPT

53

54

2. WSC1-L and sensors connect to each other via RS485/Modbus.

55

56

3. WSC1-L read value from each sensor and send uplink via LoRaWAN

57

58

59

WSC1-L is shipped with a RS485 converter board, for the easy connection to different sensors and WSC1-L. Below is a connection photo:

62

63

64

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

65

66

* All weather sensors and WSC1-L are powered by MPPT solar recharge controller. MPPT is connected to solar panel and storage battery.

67

* WSC1-L has an extra 1000mAh back up battery. So it can work even solar panel and storage battery Fails.

68

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

69

70

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

71

72

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

* Solar Panel

* Storage Battery

* MPPT Solar Recharger

77

* 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.

78

* Cabinet.

80

== 2.2 How it works? ==

81

82

(((

83

Each WSC1-L is shipped with a worldwide unique set of OTAA keys. To use WSC1-L in a LoRaWAN network, user needs to input the OTAA keys in LoRaWAN network server. After finish installation as above. Create WSC1-L in your LoRaWAN server and Power on WSC1-L , it can join the LoRaWAN network and start to transmit sensor data. The default period for each uplink is 20 minutes.

)))

Open WSC1-L and put the yellow jumper as below position to power on WSC1-L.

90

91

92

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

93

94

1. WSC1-L will auto scan available weather sensors when power on or reboot.

95

1. User can send a downlink command to WSC1-L to do a re-scan on the available sensors.

96

97

== 2.3 Example to use for LoRaWAN network ==

99

This section shows an example for how to join the TTN V3 LoRaWAN IoT server. Usages with other LoRaWAN IoT servers are of similar procedure.

100

101

102

[[image:1656042612899-422.png]]

Assume the DLOS8 is already set to connect to [[TTN V3 network >>url:https://eu1.cloud.thethings.network/]]. We need to add the WSC1-L device in TTN V3:

107

108

109

(% style="color:blue" %)**Step 1**(%%): Create a device in TTN V3 with the OTAA keys from WSC1-L.

110

111

Each WSC1-L is shipped with a sticker with the default device EUI as below:

== 2.4 Uplink Payload ==

147

148

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

149

150

* Valid Sensor Value: Use FPORT=2

151

* Other control command: Use FPORT other than 2.

152

153

=== 2.4.1 Uplink FPORT~=5, Device Status ===

154

155

Uplink the device configures with FPORT=5. Once WSC1-L Joined the network, it will uplink this message to the server. After first uplink, WSC1-L will uplink Device Status every 12 hours

(((

User can also use downlink command(0x2301) to ask WSC1-L to resend this uplink

324

325

Application platform provides a human friendly interface to show the sensor data, once we have sensor data in TTN V3, we can use Datacake to connect to TTN V3 and see the data in Datacake. Below are the steps:

326

327

328

(% style="color:blue" %)**Step 1**(%%): Be sure that your device is programmed and properly connected to the LoRaWAN network.

329

330

(% style="color:blue" %)**Step 2**(%%): Configure your Application to forward data to Datacake you will need to add integration. Go to TTN V3 Console ~-~-> Applications ~-~-> Integrations ~-~-> Add Integrations.

= 3. Configure WSC1-L via AT Command or LoRaWAN Downlink =

352

353

Use can configure WSC1-L via AT Command or LoRaWAN Downlink.

354

355

* AT Command Connection: See [[FAQ>>||anchor="H7.FAQ"]].

356

* LoRaWAN Downlink instruction for different platforms: [[Use Note for Server>>doc:Main.WebHome]](IoT LoRaWAN Server)

357

358

There are two kinds of commands to configure WSC1-L, they are:

359

360

* (% style="color:#4472c4" %)**General Commands**.

361

362

These commands are to configure:

363

364

* General system settings like: uplink interval.

365

* LoRaWAN protocol & radio related command.

366

367

They are same for all Dragino Device which support DLWS-005 LoRaWAN Stack((% style="color:red" %)Note~*~*)(%%). These commands can be found on the wiki: [[End Device Downlink Command>>doc:Main.End Device AT Commands and Downlink Command.WebHome]]

368

370

371

372

* (% style="color:#4472c4" %)**Commands special design for WSC1-L**

373

374

These commands only valid for WSC1-L, as below:

375

376

377

== 3.1 Set Transmit Interval Time ==

378

379

Feature: Change LoRaWAN End Node Transmit Interval.

380

381

(% style="color:#037691" %)**AT Command: AT+TDC**

382

384

385

386

(% style="color:#037691" %)**Downlink Command: 0x01**

387

388

Format: Command Code (0x01) followed by 3 bytes time value.

389

390

If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.

391

392

* Example 1: Downlink Payload: 0100001E ~/~/ Set Transmit Interval (TDC) = 30 seconds

393

* Example 2: Downlink Payload: 0100003C ~/~/ Set Transmit Interval (TDC) = 60 seconds

== 3.2 Set Emergency Mode ==

398

399

Feature: In emergency mode, WSC1-L will uplink data every 1 minute.

400

401

(% style="color:#037691" %)**AT Command:**

414

415

Feature: User can add or delete 3^^rd^^ party sensor as long they are RS485/Modbus interface,baud rate support 9600.Maximum can add 4 sensors.

416

417

(% style="color:#037691" %)**AT Command: **

418

419

(% style="color:blue" %)**AT+DYSENSOR=Type_Code, Query_Length, Query_Command , Read_Length , Valid_Data ,has_CRC,timeout**

420

421

* Type_Code range: A1 ~~ A4

422

* Query_Length: RS485 Query frame length, Value cannot be greater than 10

423

* Query_Command: RS485 Query frame data to be sent to sensor, cannot be larger than 10 bytes

424

* Read_Length: RS485 response frame length supposed to receive. Max can receive

425

* Valid_Data: valid data from RS485 Response, Valid Data will be added to Payload and upload via LoRaWAN.

426

* has_CRC: RS485 Response crc check (0: no verification required 1: verification required). If CRC=1 and CRC error, valid data will be set to 0.

427

* timeout: RS485 receive timeout (uint:ms). Device will close receive window after timeout

**Example:**

User need to change external sensor use the type code as address code.

433

434

With a 485 sensor, after correctly changing the address code to A1, the RS485 query frame is shown in the following table:

435

436

[[image:image-20220624143553-10.png]]

437

438

439

The response frame of the sensor is as follows:

440

441

[[image:image-20220624143618-11.png]]

442

443

444

**Then the following parameters should be:**

445

446

* Address_Code range: A1

447

* Query_Length: 8

448

* Query_Command: A103000000019CAA

449

* Read_Length: 8

450

* Valid_Data: 24 (Indicates that the data length is 2 bytes, starting from the 4th byte)

451

* has_CRC: 1

452

* timeout: 1500 (Fill in the test according to the actual situation)

453

454

455

**So the input command is:**

456

457

AT+DYSENSOR=A1,8,A103000000019CAA,8,24,1,1500

458

459

460

In every sampling. WSC1-L will auto append the sensor segment as per this structure and uplink.
