4.2 Offline configuration
First, you need to prepare
Step 1: Connect iConnector to RS485 - configuration cable via and power supply iConnector
 |
|
 |
 |
Step 2: Open Modbus tool on PC
You can download iConnector Configuration Tool with the following link:
https://filerun.daviteq.com/wl/?id=lNjzZbDo7Jwyr1x8DAD3x620tNK5u8lF
How to use the Modbus configuration software
Step 3: Open Modbus tool on PC
Unzip file and run file application "iconnector_config"
- Choose COM Port (the Port which is USB cable plugged in)
- Set the BaudRate: 9600, Parity: none
• Write in the Setting column the data to be configured into iConnector;
• Click Sync to synchronize data into iConnector;
• After synchronizing the data into iConnector, if the data displayed in the Value column shows the corresponding data, the configuration is completed.
SIM CARD CONFIGURATION
Based on the information of the mobile carrier that provides the SIM card, we configure data such as APN, username, password on the 2G/3G tab.
4.2.1 Configure CAT-M1 Band and NB1 Band
<bnd bitmap> Band bitmap in hexadecimal format without the 0x prefix.
This is the logical representation of 1 << (BandNumber - 1).
(Currently only used for RAT CAT-M1 and NB-1.)

configure multiple bands, add them up according to hexadecimal.
For example: Configure band 2, 3, 4, 5, then add (0x02 + 0x04 + 0x08 + 0x10) = 0x1E
=> Band configuration is 1E (the leading zeros can be removed)

4.2.5 Configure Apply new LTE
- After configuring we write down 1 to apply the new configuration, go back to RAT1. After execution, ICT will automatically reset to 0.
4.2.6 Configure Attach Network Times
- Number of attempts to connect to 1 RAT before switching to the next RAT when connection failed;
- RAT1 => RAT2 => RAT3 => RAT1;
- One connection attempt takes about 10-20 seconds.
4.2.7 Configure Time RAT1 (min)
- Every minute of time_RAT1 will try to reconnect with RAT1 if it is currently running in RAT2 or RAT3. Minimum 15 minutes.
4.2.8 Configure Time FOTA (min)
- After time_FOTA minutes will connect to the server of Sierra Wireless 1 time to check for FW updates or not;
- Write 0 to turn off FOTA.
→ Use to update the new FW for the HL7802 modem.
4.3 Operational principle of RAT1, RAT2, RAT3
When the ICT is started, it will connect to RAT1 first. If the connection is successful, it will run at RAT1.
- If the ICT connecting to RAT1 fails, it will try to reconnect (Attach Network Times) times.
- If not, it will be transferred to RAT2.
- If successfully connected to RAT2 it will run at RAT2.
- If the ICT connecting to RAT2 fails, it will try to reconnect (Attach Network Times) times.
- If not, it will be transferred to RAT3.
- If successfully connected to RAT3 it will run at RAT3.
- If the ICT connection to RAT3 fails, it will try to reconnect (Attach Network Times) times.
- If not, it will be transferred to RAT1.
- If successfully connected to RAT1 it will run at RAT1.
- Every time_RAT1 minutes will try to reconnect to RAT1 if it is currently running at RAT2 or RAT3.
- Write 1 to Apply new LTE then ICT will try to reconnect to RAT1 immediately (if it is currently running at RAT2 or RAT3).

Active LTE Band:
Active LTE Band: see which RAT is running, which band.
• Number 1 at the beginning of the sequence is NB1.
• Number 4 is band 3 (1800 MHz).
NOTE:
The display of RAT differs from the configuration of Cat-M1, NB1, GPRS as 0, 1, 2; NOT 1, 2, 3.
5. Installation
5.1 Installation location
Installed on a wall or in non-metal box. The bracket will be fixed on the wall or material with a planar surface with 2 x M4 screws;
ATTENTION:
DO NOT install the iConnector inside a completed metallic box or housing, because the RF signal can not pass through the metallic wall. The housing is made from Non-metallic materials like plastic, glass, wood, leather, concrete, cement…is acceptable.
5.2 IO Wiring
5.2.1 Connect Power Supply and Modbus
- Connect PWR+ and PWR- to 7..48VDC power supply via M12 Male connector
- Connect A and B to RS485 connection.
Use M12 female connection cable to connect to iConnector
5.3 Battery installation
Steps for battery installation:
Step 1: Using L hex key to unscrew M4 screws at the side of housing
Step 2: Carefully pull out the top plastic housing in the vertical direction
Step 3:Attach the battery connector of the lithium battery and the circuit board together
Step 4: Insert the top plastic housing and locking by L hex key
(NOTE: When reinstalling the cover, pay attention to put the PCB edge into the middle slot of the box inside as shown below)
5.4 Insert SIM card
- Open iConnector cover with hex key and install the SIM card;
- Please insert the SIM in the direction printed on the label.

| No. | Phenomena | Reason | Solutions |
| 1 | Data does not go to server, N/A | iConnector lost connection with server |
|
| 2 |
|
|
|
| 3 | The data posted on Globiots is wrong, the phenomenon of value is changed abnormally continuously | Configuration parameter & modbus command is wrong | Check and correctly configure parameters & modbus commands |
