netvox R718PDA Wireless RS232 Adapter

Introduction

R718PDA is a Class C type device based on the LoRaWAN open protocol of Netvox and is compatible with the LoRaWAN protocol.
R718PDA supports serial port transparent transmission. It can send the read commands to other sensors supporting RS-232 protocol according to the configured period, and the information returned by the other sensors will be directly reported to the gateway. It supports up to 128 bytes of data (depending on the current communication rate).
The serial port transparent transmission only supports RS-232 protocol.

LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power consumption. Compared with other communication methods, LoRa spread spectrum modulation method greatly increases to expand the communication distance. Widely used in long-distance, low-data wireless communications. For example, automatic meter reading, building automation equipment, wireless security systems, industrial monitoring. Main features include small size, low power consumption, transmission distance, anti-interference ability and so on.

LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers.

Power Off| Power Off
Power Off| 1. In the first 5 seconds after power on, the device will be in engineering test mode. 2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.
Network Joining
Never Joined The Network| Turn on the device to search the network. The green indicator stays on for 5 seconds: success The green indicator remains off: fail
Had Joined The Network (Not Restore to Factory Setting| Turn on the device to search the previous network. The green indicator stays on for 5 seconds: success The green indicator remains off: fail
Fail to Join The Network| Suggest to check the device verification information on the gateway or consult your platform server provider.
Function Key
Press and Hold for 5 Second| Restore to factory setting / Turn off The green indicator flashes for 20 times: success The green indicator remains off: fail
Press Once| The device is in the network: 87+ReceiveData (ReceiveData is the most recently received data) format packet The device is not in the network: the green indicator remains off
Baud Rate Configuration
Serial Transmission Rate Default Value| 9600
Configuration Method| Issue instructions through LORANWAN
Serial Transmission Rate Option| 00 Baudrate = 115200; 01 Baudrate = 57600; 02 Baudrate = 38400; 03 Baudrate = 28800; 04 Baudrate = 19200; 05 Baudrate = 9600; 06 Baudrate = 4800; 07 Baudrate = 2400

Data Report

The device will send a version package report immediately after powered on. The device has no operation before any configuration is done.

The device sends instructions through LORAWAN to configure the data that needs to be sent through RS232, and it reports the data that RS232 receives to the gateway at the same time. The device sends instructions through LORAWAN to configure the time to periodically send the data.

When RS232 interface of R718PC receives the serial port data from the RS232 device that it is connected to, it will actively report the received data to the gateway in the format of 87+ReceiveData.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://www.netvox.com.cn:8888/page/index to resolve uplink data.

Data Report Cycle Configuration Example

FPort：0x0A

GetPollSensor
PeriodReq| 0x04|
GetPollSensor PeriodRsp| 0x84| Period (2Byte, Unit: 1s)

1. Configure the device Period = 30s Downlink: 03001E Device Return: 8300 (configuration success) 8301 (configuration failure)
2. Read the device parameters Downlink: 04 Device Return: 84001E (current device parameter)

Note:
After SetPollSensorPeriodReq(CmdID:03) sets the periodical sending time to 30 seconds, R718PDA will send the command that is set by SetPollSensorRawCmdReq(CmdID:05) to the connected RS232 device every 30 seconds, and the response content of RS232 device will be reported in the format of 87(CmdID) + ReceiveData.

Data Report Configuration Example:

Installation

1. Wireless RS232 Adapter (R718PDA) has the built-in magnet. When installation, it can be attached to the surface of an object with iron conveniently and quickly. In order to make the device installation more secure, use screws (purchased) to fix the device to the wall or other surface (as the figure below).
   Note:
   Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.
   

2. The colors of wiring of RS232 serial device are as following: Yellow: TXD White: RXD Black: GND

3. Wireless RS232 Adapter (R718PDA) supports serial port transparent transmission. It can send commands to or read data of the other connected RS232 device according to the configured period. The read information will be directly reported to the gateway.

Wireless RS232 Adapter (R718PDA) can be applied to the device with RS232 serial port. For example:

• UPS (Uninterruptible power supply)
• Access control
• Hard disk player
• Other devices with RS232 serial port
  

Important Maintenance Instruction

Kindly pay attention to the following in order to achieve the best maintenance of the product:

• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
• Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.

All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly. Please take it to the nearest authorized service facility for repairing.
