LORA DTU_ZSL311

LORA DTU_ZSL311 Product Overview:

LORA DTU_ZSL311 terminal is a terminal that uses LoRa spread spectrum technology for wireless data transmission, providing users with a fully transparent data transmission mode. Supports networking in various modes such as star and mesh networks, with multiple communication modes including on-demand, broadcast, and multicast within the same network. Provides RS232/RS485 communication interfaces, making it convenient for users to network their industrial serial devices.

LORA DTU_ZSL311 product features:

Multiple working modes to meet different application scenarios, with a communication distance of 1-8km.

Anti interference, high sensitivity. LoRa technology itself has high receiving sensitivity (RSSI) and strong signal-to-noise ratio (SNR), coupled with our proprietary modulation and demodulation technology and stable and reliable product performance, making the anti-interference ability of LoRa wireless modules even stronger.

Powerful extension function

Wiring port

ZSL311 provides two power interfaces, which can only be used as a binary choice and cannot be connected simultaneously

VIN+ GND， The input voltage range of this interface is DC5-30V.

BAT+ BAT-， The input voltage range of this interface is DC3.4-4.2V.

serial port

The panel is labeled with RS232 interface (RXD TXD GND) and 485 interface, which can only be used as a binary choice.

If used simultaneously, it is necessary to ensure that the two serial ports of DTU are staggered in time when receiving serial data, otherwise conflicts may occur.

low power consumption

The ZSL series devices use a 32-bit ARM low-power CPU as the core. Combined with the unique RF communication processing technology of Zhongshan Technology, the standby working current of the whole machine has been reduced to low power consumption: 50uA

Under a power consumption of 50uA, the ZSL device is still in operation and can receive/send data at any time. Not the power consumption during sleep shutdown.

*The above data was measured in "power consumption priority mode"

Multiple network communication modes

Traditional star network - the master device can communicate with any node device.

Flexible and powerful self-organizing network

Broadcast communication - Under the same network, each device communicates with each other.

VOD communication - Under the same network, point-to-point communication can be achieved between any two devices.

Multicast communication - Under the same network, single or multiple devices can be grouped together to achieve communication between groups.

*The above three networking methods can be combined and used within the same network

Automatic relay, unrestricted communication mode

Pure relay mode - In pure relay mode, the device immediately forwards data after receiving it

Adaptive mode - serving as both a node and a relay, integrating two functions, intelligently identifying data sources, and selectively processing valid data.

LORA gateway

*Note: ZSL311, in conjunction with our company's 2G, 3G, and 4G DTUs, can facilitate the establishment of LoRa gateways for remote data transmission.

Use serial port or network configuration parameters

The LORA DTU_ZSL311 device not only allows direct configuration of parameters using local serial port cables, but also supports wireless configuration of parameters for remote devices.

As shown in the following figure:

Device A is connected to a computer through a serial port cable, and using the graphical configuration software provided by our company, the parameters of local device A can be conveniently and quickly configured, as well as the parameters of remote device B can be configured wirelessly.

*When configuring parameters wirelessly, it is necessary to ensure that the local device and the remote device are on the same network.
