1. Introduction
The R719A is a parking monitoring device which is the Class A device based on the LoRaWANTM protocol of Netvox.
It can monitor whether there is a parking space available in the parking lot.
It is compatible with the LoRaWAN protocol.
LoRa Wireless Technology:
LoRa is a wireless communication technology famous for its long-distance transmission and low power consumption. Compared
with other communication methods, LoRa spread spectrum modulation technique greatly extend the communication distance. It
can be widely used in any use case that requires long-distance and low-data wireless communications. For example, automatic
meter reading, building automation equipment, wireless security systems, industrial monitoring. It has features like small size,
low power consumption, long transmission distance, strong 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.

Any number between
1~65535
Any number between

Report
per Max Interval
When the device is turned on, it will immediately send a version package and a data report of parking status and battery
voltage.
The device sends data in the default configuration before any configuration is done.
Default setting:
ReportMaxTime: 3600s
ReportMinTime: 3600s (to detect the current voltage value per Min Interval)
Battery voltage: 0x01(0.1V)
Geomagnetic Detect Threshold: 0x28 (40) *Range:0x14-0xFFFF (0x14 is the most sensitivity)
Vehicle parking trigger:
When a car parked, 15 seconds later, sensor would send a data “CarOnOff” =01, which means that the space is parked.
When a car left, 15 seconds later, sensor would send a data “CarOnOff” =00, which means that the space is empty to park.
The parking space status will be reported according to configuration.
Note:
The device report interval will be programmed based on the default firmware which may vary.
The interval between two reports must be ReportMinTime.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver

Notes :
1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not
collect data.
2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value,
the device reports according to MinTime interval. If the data variation is not greater than the last data reported, the device
reports according to MaxTime interval.
3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up
frequently and the battery will be drained soon.
4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another
cycle of MinTime/MaxTime calculation is started.

6. Installation
2. Place a magnet above the reed switch (the U-shaped part
of the device) for 3 seconds to turn it on, connect to the
network, join to the gateway to check if the device is
operating normally and detecting the vehicle correctly, and
the installation is completed.
Note:
The magnet is a magnet accessory that comes with the
batch.
3. When the device detects that the car has entered the
parking space for 15 seconds, the reported data-- CarOnOff
bit is “01”. When the car leaves the parking space for 15
seconds, the reported data-- CarOnOff bit is “00”.
4. R719A can be applied to the smart parking lot.
1. R719A is installed in the middle of the parking space with 4
screws ( purchased by self).
Note
The device is recommended to be installed in the middle of
the parking space for best results.
Make sure that there is no obstruction above the device when
the device is turned on.
The device is turned off by default. After the device is
installed and turned on, the device needs a three-minute
warm-up time, after three minutes, the geomagnetic field can
work normally.
After fixed installation and startup, do not use magnetic
objects near the device. Otherwise, it will affect the
initialization of the device and cause the device to
malfunction.
If users need to move the device, please power off the device,
restart it after fixed installation, and wait for the device to
initialize.
Ensure that when the device is turned on and the
geomagnetism configures the initial magnetic field within
three minute
s, it cannot be parked above the device, and there
is no interference source within 5 meters of the surrounding
area.

6.1 Battery Installation
Warning:
1. When replacing the battery, it must be operated by professionals.
2. Please use two ER18505 batteries for the device, and the single battery specification is 3.6V.
3. Please note that the positive and negative poles of the battery are not reversed.
Step 1: Unscrew the six screws of the rear lock cover on the back of the device with a screwdriver as the red area in Figure 1.
Figure 1
Step 2: Remove the middle plastic cover. The plastic cover is shown in the red area in Figure 2.
Please note that the plastic cover is rectangular and pay attention to the direction when placing it.
Figure 2
Step 3: Put the battery into the battery slot of the device. The side of the battery slot marked with is the positive pole,
and the side marked with is the negative pole (with a spring). The side with of the battery is the positive
electrode, and the side with is the negative electrode as Figure 3. Please note that the positive and negative poles of
the battery should not be reversed.

6.2 Device Installation
There are three installation methods: fully buried installation, semi-buried installation and direct installation.
The installation methods are as follows.
6.2.1 Device Interference Source
There should be no metal materials such as aluminum alloy, iron, copper plate, etc. around the device.
There should be no water around the device.
Please keep the environment around the device clean and avoid the coverings on the device; otherwise, it will affect the normal
operation of the device.
6.2.2 Precautions For Battery Use
If the battery needs to be replaced within 10 minutes after the device is turned on, users need to the magnet approach to the top
cover for 10 seconds to restore the factory settings after replacing the battery. (The hardware has its own anti-battery
passivation power supply to actively eliminate the battery hysteresis.) Then, turn on the device, and it can work normally.
Note:
Please do not disassemble the device unless it is required to replace the batteries.
Do not touch the waterproof gasket when replacing the batteries.
Please use suitable screwdriver to tighten the screws (if using an electric screwdriver, it is recommended to set the torque as
4kgf) to ensure the device is impermeable.

7. Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture, or any liquid might contain minerals and thus corrode electronic circuits. If the device gets
wet, please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy
batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate
structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the nearest
authorized service facility for repair.
