Legacy Device Integration
Installed RS232, RS485 and RS422 devices cannot connect directly to modern IP networks.
INDUSTRY SOLUTION
Connect Building Systems Through One Reliable Data Network
Integrate access, HVAC, metering and building controllers with modern management platforms.
Bridge installed serial equipment to Ethernet while keeping system expansion practical and maintainable.

FIELD TO NETWORK
Communication Distance
Long cable routes and distributed equipment increase signal and installation risk.
Multi-Device Complexity
Different interfaces, branches and protocols make expansion and troubleshooting slower.
Industrial Interference
Electrical noise and ground potential differences can interrupt critical field data.
SOLUTION ARCHITECTURE
A Clear Path from Field Device to Operational Data
Use the interface and network constraint to define each connection layer before selecting a model.
