The M-4132 module is specially designed for the remote maintenance solution with
voice streaming. This module provides 2 major technologies on networking: Voice
streaming and Pair connection. The Pair connection means that the user can operate
remote COM port device via Ethernet TCP/IP protocol just like a local COM port and
the Voice streaming means the user can talk to remote operator while operate remote
COM-linked devices. Refer to the following graph.
Remote Maintenance: Establish the remote maintenance system of the equipments sold
in the world
Broadcasting system: Establish the broadcasting system in the internet or intranet
Serial application revolution: Upgrade the original serial application to network
application
