This article tells you how to use the USB to RS232 Cable (if your laptop doesn’t have RS232 port, a USB to RS232 converter is required) to upgrade your TG451 with latest version of firmware.

 

You may wonder why shall I use RS232 cable to upgrade firmware of TG451? Normally, TG451 supports firmware upgraded via WEB UI? It is because, when the device doesn’t run properly, or the Web management portal is not able to be accessed, you’ll need to use the serial port for firmware upgrade.

1. Connection of IoT Gateway TG451

1) Please connect your slave computer to RS232 port of Bivocom TG451.

2) RS232 Cable (DB9 female connector) definition

Line Color Corresponds to DB9 female connector pin Corresponding Pin to the gateway
Blue 2RX TX
Brown 3TX RX
Black 5GND GND
IoT gateway TG451 RS232 setup

Bivocom standard product package contains Console RS232 Cable (DB9 to 3 Pin), connect the 3-Pin cable to RS232 port of Bivocom gateway TG451 (the Black pin to GND port, while Brown pin to RX port, Blue pin to TX port). The other side connect to your slave computer, you may need extra RS232 to USB adapter cable if your laptop doesn’t have standard serial communication interface.

3) Setup Bivocom TG451 and connect your laptop network to TG451’s LAN by Ethernet cable, and set static IP address as “192.168.1.100”.

4) Make sure you have the RouterUpgradeTool software and the upgraded configuration file on your computer. If you don’t have them, please ask Bivocom support(support@bivocom.com). Turn on the software “RouterUpgradeTool”.

2. How to Upgrade Firmware of IoT Gateway TG451?

1) Step 1 & 2: Open RS232 Serial Port

Open the corresponding serial port by click “打开串口” and select the IP address of the NIC(Network Interface Card). You can enter the IP address manually. If you do not find the corresponding IP address or do not know the specific IP address input, you can wait for the program to automatically detect the refresh.

2) Step 3:Choose Gateway Model and Version

At this section, you can set parameters. Firstly, select model as TG451 by click “型号”(Model), “版本”version is Standard(标准), the language you can chose English(英文), SIM card mode chooses single SIM(单卡) or dual SIM(双卡), and support 212 option select No(否).

This section is not editable by default. Check here to edit the SN and MAC, or you can skip it.

3) Step 4: Choose Firwmare

Click the button “…” to select the router upgrade profile.

4) Step 5: Upload and Upgrade Firmware

Click the button “下载固件” to start downloading the latest firmware. Then re-plug the power supply.

When the two progress bars are 100%, the upgrade configuration is complete.

Firmware upgrade

3. FAQ

1) If the gateway is powered on again but no output is generated, please check whether the serial port number is correct and the serial port cable can be used.

2) If you see “配置失败” on the screen, it means configuration failed. Please check if the serial cable is properly connected.

3) If you see “IP异常,尝试重新执行 删除异常IP” on the screen, it means the network cable is properly connected, and the computer can identify the IP address of the gateway, but the correct IP is not selected. Because the IP address selected in the IP box is error. After the exception, the program will automatically try to refresh and switch the IP address for upgraded operation.

FAQ3

4) If you see “IP异常,尝试重新执行 删除异常IP”, “请检查网线是否正常连接” on the screen, it means the network cable is not properly connected. Please check the network cable.

5) During the firmware upgrade, the progress bar does not move for a long time and an abnormal timeout occurs. Check if the serial cable is properly connected. If you see “异常超时” on the screen, it generally means the serial cable is properly connected.

After all previous settings done, Bivocom TG451 will be upgraded to the latest version firmware. Contact Bivocom representative to get upgrade application and files now if you have to upgrade your firmware.

Today, we’re going to share with you the IoT based remote telecom site monitoring system, and in this article, you’ll learn what is telecom site, what systems are telecom site consisted of? What is remote telecom site monitoring system, why we need it?

 

Let’s get started.

 

What is Telecom Site?

Telecom site has played an important role is our daily life, not only for mobile phone subscribers, but also for IoT(internet of things), and IoV(Internet of Vehicles) applications.

A telecom site, cell site, or cellular base station is a cellular-enabled mobile device site where antennas and electronic communications equipment are placed—typically on a radio mast, tower, or other raised structure—to create a cell (or adjacent cells) in a cellular network.

Telecom site monitoring 1

From Barnabas Davoti

 

Telecom site normally consists of below systems

 

  • Cell Towers

A Physical structure where the antennas, cables and alarm light are attached, to transmit and receive signals, and send alarm light signals to airplanes.

 

  • Power Source

As telecom sites could be built in urban and rural areas, rooftops of high buildings in the city, or mountain tops in remote areas, so the power source is different based on the environment, but normally, it consists of AC electrical power supply, and comes with a diesel generator and battery backup system (UPS, Uninterruptible Power Supply), while for some remote areas where the electricity power supply is hard to get, we can also use solar power, or wind power to generate electricity.

 

Below are some of the main power sources normally used onsite, while battery bank and generator are mainly for backup power system when AC electrical power is unavailable, or solar panel, and wind power is limited due to bad weather condition.

 

  • AC electricity power supply
  • Solar panel
  • Wind turbine
  • Batter bank
  • Generator

 

  • BTS-Base Transceiver Station

The back-haul transmission devices are installed in shelter room, to transmit, receive combine signals, process digital signals, etc.

 

  • Security and access control systems

As the telecom site facilities are expensive, which may target equipment, cooper, fuel theft or even terrorist attack, to reduce such risk, normally, an CCTV security, intrusion alarm system, and access control system (RFID) will be required.

 

  • HVAC Systems (Heating Ventilation Air Conditioning)

To make sure the field devices can work perfectly in certain environments, especially in remote areas where the weather changed days and seasons, there normally will have an HVAC system to make sure the transmission devices work perfectly.

 

What is Telecom Site Monitoring System? Why We need it?

 

A telecom site monitoring system utilizes IoT sensors, smart devices (5g/4g IoT gateways, or RTU), and a cloud IoT platform to remotely monitor and control the key systems and parameters mentioned above to help mobile operators to reduce operational costs and the risk of theft.

 

How IoT Empowers the Telecom Monitoring System?

As there are different types of sensors or devices with different protocols to monitor, an industrial IoT gateway with rich I/O and industrial protocols is required to combine the different data in certain protocols and transfer them to a remote cloud server. Normally, the IoT gateway will come with ethernet ports, digital input, analogy input, RS232, RS485, and relay output to acquire data and control the field devices, a diagram below.

Telecom site monitoring 2

Below are some key systems and parameters to monitor

  • Energy Monitoring and Management

There will have an energy meter to monitor the power generation and consumption from generators, solar power, wind power, as well as consumption from electric power. In addition, it’s also used to monitor the health of the battery bank backup system.

 

  • Diesel Generator and Fuel Tank Monitoring

A generator is used to generate electricity to supply power for the telecom sites, so it’s important to remotely monitor its operation status, and provide predictive maintenance to reduce downtime and improve maintenance efficiency. Besides, the real-time level of the fuel tank monitor will help the operator to deliver the fuel in time.

 

  • Environment Monitoring

Weather status will affect the operation of telecom sites too, such as temperature, humidity, or natural disasters(flood), so it requires IoT sensors to remotely monitor the real-time environment and send alarms to the data center.

 

  • Security and Access Control

CCTV surveillance can be used to send real-time video streams to the data centre, together with intrusion alarm systems will help to reduce theft, while access control is good for authorizing operators to access telecom sites and maintain the equipment.

 

Conclusion

With the fast and massive deployment of 5G, we can see mobile operators will need the telecom site monitoring system to help them remotely monitor and control their field devices, reduce operational costs and the risk of theft.
