Introduction 1.1 What is RS485-LN RS485 to LoRaWAN Converter The Dragino RS485-LN is a RS485 to LoRaWAN Converter. It converts the RS485 signal into LoRaWAN wireless signal which simplify the IoT installation and reduce the installation/maintaining cost. RS485-LN allows user to monitor / control RS485 devices and reach extremely long ranges. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption. It targets professional wireless sensor network applications such as irrigation systems, smart metering, smart cities, smartphone detection, building automation, and so on. For data uplink, RS485-LN sends user-defined commands to RS485 devices and gets the return from the RS485 devices. RS485-LN will process these returns according to user-define rules to get the final payload and upload to LoRaWAN server. For data downlink, RS485-LN runs in LoRaWAN Class C. When there downlink commands from LoRaWAN server, RS485-LN will forward the commands from LoRaWAN server to RS485 devices.

Power ON Device The RS485-LN can be powered by 7 ~ 24V DC power source. Connection as below Power Source VIN to RS485-LN VIN+ Power Source GND to RS485-LN VINOnce there is power, the RS485-LN will be on. RS485 to LoRaWAN Converter User Manual 8 / 30 www.dragino.com 3. Operation Mode 3.1 How it works? The RS485-LN is configured as LoRaWAN OTAA Class C mode by default. It has OTAA keys to join network. To connect a local LoRaWAN network, user just need to input the OTAA keys in the network server and power on the RS485-LN. It will auto join the network via OTAA. 3.2 Example to join LoRaWAN network Here shows an example for how to join the TTN V3 Network. Assume user already have a LoRaWAN Gateway and set to connect to TTN. The RS485-LN in this example connected to two RS485 devices for demonstration, user can connect to other RS485 devices via the same method. The connection is as below: The LG308 is already set to connect to TTN V3 network . So what we need to now is only configure the TTN V3: Step 1: Create a device in TTN V3 with the OTAA keys from RS485-LN. Each RS485-LN is shipped with a sticker with unique device EUI: RS485 to LoRaWAN Converter User Manual 9 / 30 www.dragino.com RS485 to LoRaWAN Converter User Manual 10 / 30 www.dragino.com User can enter this key in their LoRaWAN Server portal. Below is TTN V3 screen shot: Add APP EUI in the application. RS485 to LoRaWAN Converter User Manual 11 / 30 www.dragino.com RS485 to LoRaWAN Converter User Manual 12 / 30 You can also choose to create the device manually. www.dragino.com RS485 to LoRaWAN Converter User Manual 13 / 30 Add APP KEY and DEV EUI www.dragino.com Step 2: Power on RS485-LN and it will auto join to the TTN V3 network. After join success, it will start to upload message to TTN V3 and user can see in the panel. 3.3 Configure Commands to read data There are plenty of RS485 devices in the market and each device has different command to read the valid data. To support these devices in flexible, RS485-LN supports flexible command set. User can use AT Commands or LoRaWAN Downlink Command to configure what commands RS485-LN should send for each sampling and how to handle the return from RS485 devices. 3.3.1 Configure UART settings for RS485 communication To use RS485-LN to read data from RS485 sensors, connect the RS485-LN A/B traces to the sensors. And user need to make sure RS485-LN use the match UART setting to access the sensors. The related commands for UART settings are: RS485 to LoRaWAN Converter User Manual 14 / 30 www.dragino.com AT Commands AT+BAUDR AT+PARITY AT+STOPBIT Description Example Set the baud rate (for RS485 connection). AT+BAUDR=9600 Default Value is: 9600. Options: (1200,2400,4800,14400,19200,115200) Set UART parity (for RS485 connection) AT+PARITY=0 Option: 0: no parity, 1: odd parity, 2: even parity Set serial stopbit (for RS485 connection) AT+STOPBIT=0 for 1bit AT+STOPBIT=1 for 1.5 bit AT+STOPBIT=2 for 2 bits 3.3.2 Configure RS485 sensors Some sensors might need to configure before normal operation. User can configure such sensor via PC and RS485 adapter or through RS485-LN AT Commands AT+CFGDEV. Each AT+CFGDEV equals to send a RS485 command to sensors. This command will only run when user input it and won't run during each sampling. AT Commands Description Example AT+CFGDEV This command is used to configure the RS485 AT+CFGDEV=xx xx xx xx xx xx xx xx xx xx devices; they won't be used during sampling. xx xx,m AT+CFGDEV=xx xx xx xx xx xx xx xx xx xx xx xx,m m: 0: no CRC, 1: add CRC-16/MODBUS in the end of this command RS485 to LoRaWAN Converter User Manual 15 / 30 www.dragino.com 3.3.3 Configure read commands for each sampling During each sampling, we need confirm what commands we need to send to the RS485 sensors to read data. After the RS485 sensors send back the value, it normally include some bytes and we only need a few from them for a shorten payload. To save the LoRaWAN network bandwidth, we might need to read data from different sensors and combine their valid value into a short payload. This section describes how to achieve above goals. During each sampling, the RS485-LN can support 15 commands to read sensors. And combine the return to one or several uplink payloads. Each RS485 commands include two parts: 1) What commands RS485-LN will send to the RS485 sensors. There are total 15 commands from AT+COMMAD1, ATCOMMAND2,..., to AT+COMMANDF. All commands are of same grammar. 2) How to get wanted value the from RS485 sensors returns from by 1). There are total 15 AT Commands to handle the return, commands are AT+DATACUT1,AT+DATACUT2,..., AT+DATACUTF corresponding to the commands from 1). All commands are of same grammar. 3) Some RS485 device might has longer delay on reply, so user can use AT+CMDDL to set the timeout for getting reply after the RS485 command is sent. For example AT+CMDDL1=1000 to send the open time to 1000ms After we got the valid value from each RS485 commands, we need to combine them together with the command AT+DATAUP. Below are examples for the how above AT Commands works. AT+COMMANDx : This command will be sent to RS485 devices during each sampling, Max command length is 14 bytes. The grammar is: AT+COMMANDx=xx xx xx xx xx xx xx xx xx xx xx xx,m xx xx xx xx xx xx xx xx xx xx xx xx: The RS485 command to be sent m: 0: no CRC, 1: add CRC-16/MODBUS in the end of this command For example, if we have a RS485 sensor. The command to get sensor value is: 01 03 0B B8 00 02 46 0A. Where 01 03 0B B8 00 02 is the Modbus command to read the register 0B B8 where stored the sensor value. The 46 0A is the CRC-16/MODBUS which calculate manually. RS485 to LoRaWAN Converter User Manual 16 / 30 www.dragino.com In the RS485-LN, we should use this command AT+COMMAND1=01 03 0B B8 00 02,1 for the same. AT+DATACUTx : This command defines how to handle the return from AT+COMMANDx, max return length is 45 bytes. AT+DATACUTx=a,b,c a: length for the return of AT+COMMAND b:1: grab valid value by byte, max 6 bytes. 2: grab valid value by bytes section, max 3 sections. c: define the position for valid value. Examples: Grab bytes: Grab a section. Grab different sections. RS485 to LoRaWAN Converter User Manual 17 / 30 www.dragino.com 3.3.4 Compose the uplink payload Through AT+COMMANDx and AT+DATACUTx we got valid value from each RS485 commands, Assume these valid value are RETURN1, RETURN2, .., to RETURNx. The next step is how to compose the LoRa Uplink Payload by these RETURNs. The command is AT+DATAUP. Examples: AT+DATAUP=0 Compose the uplink payload with value returns in sequence and send with A SIGNLE UPLINK. Final Payload is PAYVER + VALID Value from RETURN1 + Valid Value from RETURN2 + ... + RETURNx Where PAYVER is defined by AT+PAYVER, below is an example screen shot. RS485 to LoRaWAN Converter User Manual 18 / 30 www.dragino.com Examples: AT+DATAUP=1 Compose the uplink payload with value returns in sequence and send with Multiply UPLINKs. Final Payload is PAYVER + PAYLOAD COUNT + PAYLOAD# + DATA 1) PAYVER: Defined by AT+PAYVER 2) PAYLOAD COUNT: Total how many uplinks of this sampling. 3) PAYLOAD#: Number of this uplink. (from 0,1,2,3...,to PAYLOAD COUNT) 4) DATA: Valid value: max 8 bytes for each uplink so each uplink <= 11 bytes. For the last uplink, DATA will might less than 8 bytes So totally there will be 3 uplinks for this sampling, each uplink include 8 bytes DATA DATA1=RETURN1 Valid Value + the first two of Valid value of RETURN10= 20 20 0a 33 90 41 02 aa DATA2=3rd ~ 10th byte of Valid value of RETURN10= 05 81 0a 20 20 20 20 2d DATA3=the rest of Valid value of RETURN10= 30 Below are the uplink payloads: RS485 to LoRaWAN Converter User Manual 19 / 30 www.dragino.com 3.3.5 Uplink on demand Except uplink periodically, RS485-LN is able to uplink on demand. The server send downlink command to RS485-LN and RS485 will uplink data base on the command. Downlink control command: 0x08 command: Poll an uplink with current command set in RS485-LN. 0xA8 command: Send a command to RS485-LN and uplink the output from sensors. 3.3.6 Uplink on Interrupt RS485-LN support external Interrupt uplink since hardware v1.2 release. Connect the Interrupt pin to RS485-LN INT port and connect the GND pin to V- port. When there is a high voltage (Max 24v) on INT pin. Device will send an uplink packet. 3.4 Uplink Payload RS485 to LoRaWAN Converter User Manual 20 / 30 Size(bytes) Value 1 PAYLOAD_VER www.dragino.com Length depends on the return from the commands If the valid payload is too long and exceed the maximum support payload length in server, server will show payload not provided in the LoRaWAN server. 3.5 Configure RS485-LN via AT or Downlink User can configure RS485-LN via AT Commands or LoRaWAN Downlink Commands There are two kinds of Commands: Common Commands: They should be available for each sensor, such as: change uplink interval, reset device. For firmware v1.3, user can find what common commands it supports: http://wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Comm ands Sensor Related Commands: These commands are special designed for RS485-LN. User can see these commands below: 3.5.1 Common Commands: They should be available for each of Dragino Sensors, such as: change uplink interval, reset device. For firmware v1.3, user can find what common commands it supports: http://wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands 3.5.2 Sensor related commands: RS485 Debug Command This command is used to configure the RS485 devices; they won't be used during sampling. AT Command AT+CFGDEV=xx xx xx xx xx xx xx xx xx xx xx xx,m m: 0: no CRC, 1: add CRC-16/MODBUS in the end of this command Downlink Payload Format: A8 MM NN XX XX XX XX YY Where: MM: 1: add CRC-16/MODBUS ; 0: no CRC NN: The length of RS485 command XX XX XX XX: RS485 command total NN bytes YY: How many bytes will be uplink from the return of this RS485 command, if YY=0, RS485-LN will execute the downlink command without uplink; if YY>0, RS485-LN will uplink total YY bytes from the output of this RS485 command RS485 to LoRaWAN Converter User Manual 21 / 30 www.dragino.com For example, To connect a Modbus Alarm with below commands. The command to active alarm is: 0A 05 00 04 00 01 4C B0. Where 0A 05 00 04 00 01 is the Modbus command to read the register 00 40 where stored the DI status. The 4C B0 is the CRC-16/MODBUS which calculate manually. The command to deactivate alarm is: 0A 05 00 04 00 00 8D 70. Where 0A 05 00 04 00 00 is the Modbus command to read the register 00 40 where stored the DI status. The 8D 70 is the CRC-16/MODBUS which calculate manually. So if user want to use downlink command to control to RS485 Alarm, he can use: A8 01 06 0A 05 00 04 00 01 00: to activate the RS485 Alarm A8 01 06 0A 05 00 04 00 00 00: to deactivate the RS485 Alarm A8 is type code and 01 means add CRC-16/MODBUS at the end, the 3rd byte is 06, means the next 6 bytes are the command to be sent to the RS485 network, the final byte 00 means this command don't need to acquire output. Set Payload version This is the first byte of the uplink payload. RS485-LN can connect to different sensors. User can set the PAYVER field to tell server how to decode the current payload. AT Command: AT+PAYVER: Set PAYVER field = 1 Downlink Payload: 0xAE 01 Set PAYVER field = 0x01 0xAE 0F Set PAYVER field = 0x0F Set RS485 Sampling Commands AT+COMMANDx or AT+DATACUTx These two commands are use to configure how the RS485-LN polling data from Modbus device. Detail of usage please see : polling RS485 device. AT Command: AT+COMMANDx: Configure RS485 read command to sensor. AT+DATACUTx: Configure how to handle return from RS485 devices. Downlink Payload: 0xAF downlink command can be used to set AT+COMMANDx or AT+DATACUTx. Note: if user use AT+COMMANDx to add a new command, he also need to send AT+DATACUTx downlink. Format: AF MM NN LL XX XX XX XX YY Where: MM: the ATCOMMAND or AT+DATACUT to be set. Value from 01 ~ 0F, RS485 to LoRaWAN Converter User Manual 22 / 30 NN: 0: no CRC; 1: add CRC-16/MODBUS ; 2: set the AT+DATACUT value. LL: The length of AT+COMMAND or AT+DATACUT command XX XX XX XX: AT+COMMAND or AT+DATACUT command www.dragino.com YY: If YY=0, RS485-LN will execute the downlink command without uplink; if YY=1, RS485-LN will execute an uplink after got this command. Example: AF 03 01 06 0A 05 00 04 00 01 00: Same as AT+COMMAND3=0A 05 00 04 00 01,1 AF 03 02 06 10 01 05 06 09 0A 00: Same as AT+DATACUT3=16,1,5+6+9+10 AF 03 02 06 0B 02 05 07 08 0A 00: Same as AT+DATACUT3=11,2,5~7+8~10 Fast command to handle MODBUS device AT+MBFUN is valid since v1.3 firmware version. The command is for fast configure to read Modbus devices. It is only valid for the devices which follow the MODBUS-RTU protocol. This command is valid since v1.3 firmware version AT+MBFUN can auto read the Modbus function code: 01, 02, 03 or 04. AT+MBFUN has lower priority vs AT+DATACUT command. If AT+DATACUT command is configured, AT+MBFUN will be ignore. Example: AT+MBFUN=1 and AT+DATACUT1/AT+DATACUT2 are not configure (0,0,0). So RS485-LN. AT+COMMAND1= 01 03 00 10 00 08,1 --> read slave address 01 , function code 03, start address 00 01, quantity of registers 00 08. AT+COMMAND2= 01 02 00 40 00 10,1 --> read slave address 01 , function code 02, start address 00 40, quantity of inputs 00 10. RS485 to LoRaWAN Converter User Manual 23 / 30 RS485 command timeout www.dragino.com Some Modbus device has slow action to send replies. This command is used to configure the RS485-LN to use longer time to wait for their action. Default value: 0, range: 0 ~ 65 seconds AT Command: AT+CMDDLaa=hex(bb cc)*1000 Example: AT+CMDDL1=1000 to send the open time to 1000ms Downlink Payload: 0x AA aa bb cc Same as: AT+CMDDLaa=hex(bb cc)*1000 Example: 0xAA 01 00 01 Same as AT+CMDDL1=1000 ms Uplink payload mode Define to use one uplink or multiple uplinks for the sampling.
