2. Introduction

STHC-B is same as STHC, is a Smart IoT Gateway, aka iConnector, a main component in any IoT application. However, STHC-B is operated by a Primary battery 3.6V, suitable for applications where no grid power like Water pipeline, water network...In addition, STHC-B is also powered by external power supply 7..48VDC or Solar panel system. STHC-B has built-in 1 Pulse input to read the Pulse from flow meter...and 01 Digital input can connect to Pressure sensor, Level, Temperature, Humidity... Data will be sent back to server for data logging, data analytics, monitoring & controls...With Ultra low power design, it can uses 01 battery size D for up to 05 years (depend on configuration of data logging and sending).

4. Applications

5. Operation principle

5.1 Process of measurement

When the sensor sampling interval is reached, for example, 2 minutes (Battery Mode), iConnector will wake up and turn ON the power to supply power to the external sensor to start measuring. Depending on the type and characteristics of the external sensor, it may take a certain time to complete the measurement.

For example, the measurement time is 200mS, after this time, iConnector will read the value of the sensor by I2C, it will switch the power OFF to the external sensor to save energy.

If we supply external power through M12 connector, iConnector will run realtime.

After reading the sensor value, the raw data is X, it can be scaled to any technical value by the following formula:

Y = aX + b

Where

X: the raw value from sensor

Y: the calculated value for parameter 1's value or parameter 2's value

a: constant

b: constant

 

So, if there is no user setting for a and b ==> Y = X

The Y value will be compared with Lo and Hi threshold.

5.2 Configuration via Memory map

5.3 Offline configuration

5.3.1 Connection

First, you need to prepare

• Step 1: Open the cover of the iConnector

• Step 2:Connect the Configuration Cable to the UART Port in iConnector

• Step 3: Power the iConnector via M12 male connector on iConnector

• Step 4: Connect the USB port of the Configuration Cable to the Computer

 

 

5.3.2 Configuration tool

• You can download Configuration Tool with the following link:

https://filerun.daviteq.com/wl/?id=s5QApxosVNZLbATxi0TtKVoJX4ms1PxD 

• 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

• Click “ Connect “ untill the Status displays “disconnected” to “connected“. It means the iConnector is being connected with computer;
• Configuration parameters:

• • 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.

5.4 SIM configuration

iConnector 3G uses micro-SIM and needs to be configured to use the data network

1. Open iConnector cover and install the SIM card
2. 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

5.5 Configure sensor parameters on the iConnector

5.5.1 Configure I2C_Sensor tab

We configure the parameters of 4-20mA sensor in I2C Sensor tab:

I2C: sample_rate (sec)	sensor reading cycle, e.g: 60 seconds.
I2C: calc_time (ms)	time of supplying power to the sensor before reading the I2C, e.g: 200 ms.
I2C: num_of_sample	The number of ADC samples taken in a reading of sensor data, the more samples the longer the sensor reading time. For example: 8 samples with each sample have a reading time of 10ms, then the total sampling time is 80ms.
I2C: prm1_a	The a constants after calculation according to the formula
I2C: prm1_b	The b constants after calculation according to the formula
I2C: prm1_hi_cut	Cut the upper threshold of I2C e.g: If prm1_scaled_value > prm1_hi_cut then prm1_scaled_value = prm1_hi_cut
I2C: prm1_lo_cut	Cut the lower threshold of I2C e.g: If prm1_scaled_value < prm1_lo_cut then prm1_scaled_value = 0.
I2C: sensor type	Sensor type = 20 means that the I2C sensor reads 4-20mA
I2C: error status	if error status = 0, it means the sensor reading is OK, else error status = 1 is faulty.
I2C: prm1_scaled_value	The measured value has been scaled for the sensor Formula to calculate scale: prm1_scaled_value = prm1_raw_value * prm1_a + prm1_b
I2C: prm1_raw_value	Raw sensor value read from I2C

5.5.2 Operation mode of iConnector with different power sources

When iConnector only works with D type battery:

• 3G network will turn off, only when the 3G data sending cycle is turned on to send data, after sending it will turn off.
• Not sending a ping leads to iConnector not running realtime, unable to sync from the server.
• Unable to configure from iConfig software.

When iConnector is connected to 7-48VDC power source:

• 3G network is always on, running Ping and ready to receive realtime, synchronization, running full of features.
• Can be configured from iConfig software.

7. Troubleshooting

No.	Phenomena	Reason	Solutions
1	The value of the sensor is 0	Sensor connecting 4-20mA is loose/not connected	Check sensor connection
2	The iConnector does not connected to the sever	No power supply The network information of the SIM card data is incorrect No SIM card inserted	Check the power supply Check that the battery is empty or not installed correctly Check the sim card configuration section
3	The battery drains quickly	Turn On/Off tab configuration is incorrect	Check the configuration of the Turn On/Off tab
