Legacy Device Integration
Installed RS232, RS485 and RS422 devices cannot connect directly to modern IP networks.
CONNECTION NEED
Extend Serial Communication Across Remote Industrial Sites
Connect distributed RS232 and RS485 equipment where long cable runs or trenching are impractical.
Use wireless serial links to reduce field cabling and support point-to-point or multipoint topologies.

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.
