The first miniature rail-type LoRa wireless data transmission radio - E95M-DTU (400SLxx-485) has a variety of transmission methods, ultra-small size, and can be installed quickly. Military-grade LoRa modulation technology is adopted, which brings longer communication distance and stronger anti-interference ability.
LoRa spread spectrum technology
Using the latest LoRa spread spectrum technology, it has a longer distance and more powerful performance than traditional LoRa data transmission radios.
Serial port firmware upgrade
Support serial port firmware upgrade, which is more convenient to update firmware. After the product is released, users can easily update and upgrade the firmware program in the product through the reserved communication port.
AT command configuration
The product has convenient and fast AT command configuration, and supports three types of AT instructions in the configuration mode: command instructions, setting instructions and query instructions.
Long-distance communication
It supports ModBus protocol transmission, wirelessly sending command packets, and remotely configuring or reading radio station parameters. It can realize multi-level relay networking, effectively extend the communication distance, and realize ultra-long-distance communication. The E95M-DTU (400SL22-485) has a communication distance of up to 5Km under ideal conditions, and the E95M-DTU (400SL30-485) can reach 10Km under ideal conditions.
The transmit power is multi-level adjustable
The transmit power is 22/30dBm, and supports multi-level adjustability, and all technical indicators meet industry standards.
Hidden buttons
The hidden button is used to switch the working mode to avoid false triggering, and the equipment works more reliably. Simple and efficient power supply design, support power supply device or crimping method, support 8~28V (DC) power supply.
The air speed is adjustable in 6 levels
It supports the data transmission rate of 2.4K~62.5Kbps to meet the needs of more IoT applications.
RSSI signal strength + LBT function
It has an RSSI signal strength indication function for evaluating signal quality, improving communication networks, and measuring distances. At the same time, it also supports the LBT function, and the radio station automatically waits for transmission according to the current ambient noise intensity. Greatly improve the communication success rate of the radio station in harsh environments
。
Data encryption
The length of the subpackage can be set, and the communication key can be checked to effectively prevent the data from being intercepted and fully ensure the data security.
In addition, the data transmission radio also has multiple protection functions such as power supply reverse connection protection, overconnection protection, antenna surge protection, etc., which greatly increases the reliability of the radio. The communication port and power interface adopt isolation and high protection. Powerful software functions, all parameters can be programmed: such as power, frequency, air rate, address ID, etc. With a built-in watchdog and precise time layout, the radio will automatically restart in the event of an abnormality and continue to work according to the previous parameter settings.
