The wireless data transmission equipment is usually DTD433M band, which can provide highly stable, reliable and low-cost data transmission. It provides transparent RS232/ RS485 interface It has the characteristics of convenient installation and maintenance, strong diffraction ability, flexible networking structure, and wide coverage, and is suitable for applications with many points and scattered, complex geographical environment, etc.

The device provides point-to-point communication, and can also realize point-to-point communication without programming and wiring. General electrician commissioning can also be passed. Wireless data transmission equipment is widely used in the field of wireless data transmission. Typical applications include data acquisition, detection, alarm, process control, etc. in remote control, remote sensing, and telemetry systems.
