Before Internet (B.I.), traditional device use RS232 output port to
communicate with PC
Drawbacks of serial communication
Advantage of TCP/IP
After Internet (A.I.), traditional device with RS232 output need a PC to
connect to Internet,
until the invention of LinkServer
Various output protocols• Device with Analog output

• Device with RS232 output

To be used within LinkServer environment
• For Device with Analog output– Require 3 converters:
AI->RS485->RS232->TCP/IP
• For Device with RS485 output– Require 2 converters
RS485->RS232->TCP/IP
• For Device with RS232 output– Require only 1 converter

Conclusions
• Sensors and Devices can be integrated through FS and LS and accessed through Internet with only 1 fixed IP.
• FS and LS can be integrated to establish SA or MA (Multi-Agent) Supervisory or Distributed Control and Data/Image Acquisition System.
