With the rapid development of the Internet of Things (IoT), low- and medium-speed IoT scenarios place higher demands on the stability, cost-effectiveness, and convenience of communication modules.
The 4G CAT.1 module, a meticulously crafted IoT communication solution by UBS Electronics, boasts industrial-grade quality, multi-scenario adaptability, and user-friendly operation, making it the preferred product for remote meter reading, industrial control, and other scenarios. It perfectly aligns with the current industry trend of Cat.1 modules dominating the low-to-medium speed IoT market.
Core Positioning: A Highly Efficient and Stable IoT Communication Bridge
The LTE 146A is a 4G CAT.1 IoT communication module that uses direct AC 220V power supply. It focuses on both transparent communication and Bluetooth configuration, and is specifically designed for connecting IoT terminal devices to the network.
Its core application scenario is remote meter reading-the server can transmit data to the electricity meter through the module to realize remote data collection; the module communicates with the electricity meter through RS485 and with the server through a stable 4G cellular network. It also supports Bluetooth connection of mobile phones, making it easy to read and configure the module's working parameters, and building a full-link intelligent connection channel of "device-module-server".
Core Advantages: Four Key Highlights to Solve IoT Communication Pain Points
Industrial-Grade Quality, Stable, Durable, and Interference-Resistant
The module adopts industrial-grade design standards, adapting to harsh working environments: operating temperature ranges from -25℃ to +75℃, humidity ranges from 20% to 90%, and protection level reaches IP30, easily handling various complex scenarios such as industrial sites and outdoor meter boxes. It also boasts low power consumption, with an average power consumption of only 1W and an average current of 80mA, balancing energy saving and long-term stable operation, requiring no frequent maintenance and significantly reducing operating costs.
Multi-mode communication, adapting to diverse needs
- 4G CAT.1 network: Relying on a mature 4G cellular network, it replaces traditional 2G/3G solutions, offering wider coverage and stronger stability to meet long-term usage requirements;
- RS485 interface: Equipped with one RS485 communication interface, supporting multiple baud rates from 1200bps to 9600bps, with a default baud rate of 9600 8N1. It can cascade up to 32 meters, with a maximum cable length of 50 meters, suitable for centralized meter reading scenarios;
- Bluetooth function: Supports Bluetooth connection to mobile phones, and parameter configuration can be completed through a mini-program. The indoor communication distance exceeds 50 meters, and it can also receive broadcasts from other Bluetooth devices of the same brand. A backed-up downlink communication interface is reserved, adapting to multi-device linkage scenarios.
Easy configuration, quick and easy to use. Supports three configuration methods
Bluetooth mini-program, RS485 local host computer, and cellular network. Serial port parameters (baud rate, parity, etc.), network parameters (IP, Port, Apn, etc.), and heartbeat cycle (adjustable from 1-60 minutes, default 5 minutes) can be flexibly configured. A manual restart is all that's needed for the configuration to take effect. It also supports serial AT commands and network AT commands for configuration, meeting the personalized needs of professional users. No complex debugging is required, significantly improving deployment efficiency.
Intelligent Monitoring, Clear Status Indicator
The panel is equipped with 4 LED indicators, each flashing 5 times consecutively upon power-on to provide real-time feedback on device status:
- Power Indicator (PWR): Solid red light indicates normal power supply;
- Run Indicator (RUN): Solid green light indicates connection to the server; flashing at 1-second intervals indicates no connection, providing a clear view of network status;
- Communication Indicator (COMM): Flashing red light indicates receiving data; flashing green light indicates sending data, monitoring data transmission in real-time;
- Bluetooth Indicator (BT): Solid blue light indicates successful Bluetooth connection; off light indicates disconnection; flashing at 0.5-second intervals during data transmission.
Key Parameters: Robust Configuration for Stable Operation
Power Supply: AC 120V~240V, compatible with household and industrial voltages;
Network Protocol: Supports TCP/UDP protocols, default TCP client mode, supports automatic reconnection (maximum reconnection interval 3 minutes);
Transparent Transmission Capability: Supports transparent transmission between cellular networks and RS485, with a maximum single data frame size of 1024 bytes;
Installation Method: 2TE size, DIN Rail standard rail mounting, 90mm mounting spacing (Model: 4G146-VA), suitable for industrial cabinets, flexible and space-saving installation;
Other Configurations: SMA interface antenna (standard short antenna, optional long antenna), supports SIM card insertion, supports remote upgrades, ensuring long-term product compatibility and upgradeability.
Application Scenarios: Focusing on Core Functions, Empowering Multiple Fields
The core module is used in remote meter reading scenarios, and is also compatible with low-speed transmission scenarios in the Internet of Things (IoT) such as industrial control and intelligent monitoring. It is particularly suitable for scenarios requiring centralized equipment management, remote data acquisition, and convenient parameter configuration, such as centralized meter reading in residential communities, data transmission of industrial equipment, and networking of smart terminals. With its high cost-effectiveness and stable performance, it has become the preferred communication module for upgrading IoT terminals, helping enterprises achieve digital and intelligent transformation.
