1. Product Introduction
The WISENMESHWAN® 4-Channel RS485 Interface Node is one of the key products in our
patented WISENMESHWAN® geotechnical safety monitoring system. Working together with the WISENMESHWAN®
gateway product and node products, it intelligently delivers the real-time data from all different sensors outputting
RS485 signal to the information centre.
The WISENMESHWAN® 4-Channel RS485 Interface Node operates using our core technology, i.e., the
WISENMESHWAN® Low Power, Intelligent, Wireless Sensor Network protocol, together with its internal high precision
RS485 module and power unit. This product satisfies the three fundamental identities of the system:
A. Network Life Span: to maximise battery life across the mesh network as a whole;
B. Network Data Arrival Rate: to minimise data packet loss;
C. Single Node Environmental Coverage: to maximise radio coverage.
Our product has IP66 and is designed to work in a tough environment. It is small in size, reliable in performance, easy
for maintenance, has high precision during sampling, and has strong immunity to radio-interference.

4 sets of laser sensors can be hosted in this product, each can be used for long term distance monitoring between two
specific points, such as horizontal convergence of a tunnel.
Note: Vcc_Out Switch can supply different output voltages, e.g., when set as Switch = 2, 12V is outputted to laser
sensors;
