TCP Client Mode
In TCP Client mode, NPort 5200 can
actively establish a TCP connection to a
pre-defined host computer when serial data
arrives.
After the data has been transferred, NPort
5200 can automatically disconnect from the
host computer by using the TCP alive
check time or Inactivity time settings.
Refer to Chapter 5 for more details.
As illustrated in the figure, data
transmission proceeds as follows:
1. The NPort 5200 configured for TCP
Client Mode requests a connection
from the host.
2. Once the connection is established,
data can be transmitted in both
directions—from the host to the NPort
5200, and from the NPort 5200 to the
host.
UDP Mode
Compared to TCP communication, UDP is
faster and more efficient. In UDP mode, you
can unicast or multicast data from the serial
device to one or multiple host computers,
and the serial device can also receive data
from one or multiple host computers, making
this mode ideal for message display
applications.
Real COM Mode
NPort 5200 comes equipped with COM
drivers that work with Windows
95/98/ME/NT/2000/XP systems, and also
TTY drivers for Linux systems. The driver
establishes a transparent connection
between host and serial device by mapping
the IP:Port of the NPort 5200’s serial port
to a local COM/TTY port on the host
computer.
