These documents are helpful to understand the DO200 Parking Occupation Sensor’s
following:
▪Function of Device
▪How to install SIM card?
▪Protocol and API
▪Hardware Interface(debug/configure interface and battery interface )
▪Modify equipment parameters ( upload interval and APN,IP ....)
▪FAQ
2 Device Function DO200_NB-IoT Parking Occupation
Sensor's
Function:The device can detect if the parking space is occupied. When the vehicle is
detected to enter or leave, the sensor will be triggered to report the data.
When the device is restarted and the device is restarted, the sensor will learn the
surrounding environment, so it is considered to be a car-free state at this time.
3 How to install NB-IoT SIM card?
NB-IoT Sim card:MICRO card,;the frequency band of the SIM card used needs to be
the same as the device frequency band.
Insert NB card: sensor use self-elastic card slot, please find the card slot and insert
the NB card(If you want to change or remove the card, please press the card and it
will pop up automatically.).
Please pay attention to the installation direction of the card, as shown below:

4 How to restart sensor through magnet?
Magnet:
Move the magnet around the probe one turn and remove the magnet. This process
restarts the device. If the device is successfully rebooted, the device will report a
data that is displayed as being moved and the current full/empty state.

6.3 Configure device parameters (upload time, APN etc.)
After completing the two steps 6.1 and 6.2, you can refer to this step to configure
the corresponding parameters through the serial port software.
1 serial port software parameter setting
Open the serial port software. The default serial port information is shown in Figure
6.6.
The parameters required for the DO200 serial port are shown in Figure 6.7;
Port number ( you can select port Number from device manager of your system)

2 Connect the device's power(battery)
Connect the capacity and battery to the connector location on the motherboard as
shown in Figure 6.8:
Figure6.8 Connect the battery
3 Send command
When the battery is connected, you can see some information output from the serial
port. At this point, the device starts working and can send commands. At this time,
the corresponding parameters can be configured to configure the required
parameters.
Note: when the serial show “sleep”,mean that the sensor have come into sleep mode
Sending instructions at this time is invalid.so you need to restart the sensor by
magnet.
For example 1: change upload time to 10 hours
The command is: 8888010A, as shown in figure6.9,

Figure6.9
Note: you can change the time from 1-168h. It is 24h by default. Please refer to the protocol for the format of the
commands.
For example 2:Configure APN to internet
1 Command：$GA01internet;;;35
2 Enter the command, click Enter, and click Send command. If the command is sent
successfully, you can receive the reply “APN Info: internet” as shown in Figure 6.11.
But if you receive the WRONG CHECKSUM **（such as:WRONG CHECKSUM 27）,
as shown in figure6.10;the **is the right checksum, Please modify the check code in
the command to be correct, so the correct command is $GA01internet;;;27, then
send the correct again ,as shown in6.11;

Notes:
1 After the device enters sleep mode, the sending command is invalid;
2 Before sending command, please click on the enter, and then send;
3 Check whether the RX and TX of the TTL and the device are correctly connected. If
the connection is reversed, no output is displayed on the serial port after the device

is powered on, and the device can not be configured.
4 if you want to change other parameters,please send the corresponding command
in the same way. Please refer to the product agreement for detailed command
instructions.
7 Protocol and API Interface
The communication protocol(API Interface) is confidential is only open for customer
who has purchase the device and sign the NDA(non-disclosure agreement) file with
CNDingtek and his own Company. Please contact our sales team
[email protected] if you want to integrate the protocol/API with your own
system.
8 FAQ
Q1 Why can not I see the device data?
A1:no battery connected;
Considering shipping rules, some is not connected for battery. So user should open
cover and connect battery with the pcb board. For some version with magnetic part
outside, please remove the magnetic part, then the battery will power on the sensor.
A2:The APN is wrong;
Different country is with different NB-IoT network, 800/850/900/700Mhz and etc.
Please confirm the frequency or APN is correct.
A3:The server IP is limited;
Some supplier limit the server IP. Please make sure your own server is in the white
list or user the supplier server directly.
A4: there is no NB card in sensor, or insert card wrong;
Please the check the NB card.
Q2 If we can modify the ip and the APN？
yes, you can change the IP and the APN through serial port. Please refer to the
part3 of this document.
Q4 Where to view the data?
Web application or API; We can offer the web application or the API.
