4. Transparent TCP/IP connections among serial ports
In real world environment, there are often such requirements: an
RS-232 port of specific equipment at location A needs to be connected with an
RS-232 interface of specific equipment in location B. As location A and location
B are connected with TCP/IP networks, it is necessary to have the equipment
capable of establishing a transparent TCP/IP channel between the two serial
ports.
GPORT serial port equipment server is an ideal solution for this requirement.
With two GPORT located at location A and location B respectively and one of
them set up into the TCP Server mode and the other into the TCP Client mode,
the GPORT will establish TCP connection automatically when started, building a
transparent TCP/IP channel between the two RS-232 serial ports.
5.
Satisfying the redevelopment requirement of the clients
With standard LINUX as the core of the system,
GPORT
can be regarded as
a
LINUX PC
with multi-serial port cards and network interface cards to clients
with redevelopment requirements, who can autonomously structure the
application.
The clients are sure to make such choices when standard application cannot meet
their requirements.
For example:
A. When data security becomes extremely important, and it is necessary to take
into consideration of local storage when the network fails and of data encryption
in transmission;
B.
For Local data processing, where the data collected needs to be transformed into
uniform formats for the servers (protocol transformation); and for some unconventional
equipment situations that need prioritized local processing to avoid time delays caused by
network failures.
