TCP Client Mode
In TCP Client mode, the module actively
establishes a TCP connection to a specific
network host when data is received from the
attached serial device. After the data has been
transferred, the module can automatically
disconnect from the host computer through the
Inactivity time settings. Please refer to Chapter
8 for details on these parameters.
Data transmission proceeds as follows:
1. The module requests a connection from the
host.
2. The connection is established and data can
be transmitted in both directions between
the host and device.
UDP Mode
UDP is similar to TCP but is faster and more
efficient. Data can be broadcast to or received
from multiple network hosts. However, UDP
does not support verification of data and would
not be suitable for applications where data
integrity is critical. It is ideal for message
display applications.
Real COM Mode
Real COM mode is designed to work with
drivers that are installed on a network host.
COM drivers are provided for Windows
systems, and TTY drivers are provided for
Linux and UNIX systems. The driver
establishes a transparent connection to the
attached serial device by mapping a local serial
port to the module’s serial port. Real COM
mode supports up to four simultaneous
connections, so multiple hosts can collect data
from the attached device at the same time.
