M-System Wireless I/O System employs a licence-free 900 MHz ISM band module. Compared with 2.4 GHz / 5 GHz wireless LANs and other wireless networks dedicated for instrumentation using higher frequency bands, the 900 MHz band ensures stable communication quality for a long distance transmission, suitable for telemetering, multiplex transmission systems and data logging applications with various sensors/devices including low-speed moving entities.
Modbus-RTU transparent devices can easily replace existing wired ones, and various industry standard sensors/devices can be added to the network.

Remote monitoring and control of an equipment using mobile interface


Multi-hop wireless communication is a wireless network conveying data through a number of wireless communication devices in a "bucket-brigade" manner.
Relaying paths are automatically switched to an alternative one when one section of the connection is weak.
IUp to 100 child stations connect to a single parent station. The communications distance between stations can be up to 0.62 miles (1 km), thus making it possible to construct a wireless network in a wide range.

Remote monitoring and control of an equipment using mobile interface

Modbus Master (PC side) communicates with Slave Devices in multi drop connection on the wired side (RS-485) via wireless connectionusing Modbus/TCP and RTU protocols.

Triple-Reflection System

M-System’s original triple-reflection design prevents the LED lights from wasteful diffusion and ensures effective and even lighting in obliquely downward directions.



Nondirectional antenna (360°horizontal)


Network Connection

RJ-45 connector for Ethernet is provided at the bottom of the tower for easy wiring.


Five-layer, Five-color LED Modules
in Free Combination

Number of LED module layers can be specified from one to five when ordering. Five colors (red, amber, green, blue and white) can be freely combined for each module.
