NE-4000T Series User's Manual

Real COM Mode (NE-4000T-RC)

NE-4000T-RC comes equipped with COM
drivers that work with Windows
95/98/ME/NT/2000/XP systems. The driver
establishes a transparent connection between
host and serial device by mapping the IP:Port
of the NE-4000T-RC's serial port to a local
COM port on the host computer.
The important point about Real COM Mode is that it allows users to continue using RS-232 serial
communications software that was written for pure serial communications applications. The driver
intercepts data sent to the host's COM port, packs it into a TCP/IP packet, and then redirects it
through the host's Ethernet card. At the other end of the connection, the NE-4000T-RC accepts the
Ethernet frame, unpacks the TCP/IP packet, and then transparently sends it to the appropriate
serial device.

TCP Server Mode (NE-4000T-TS)

NE-4000T-TS uses TCP Server mode to establish the Serial-to-Ethernet connection.
NE-4000T-TS provides a unique IP:Port address on a TCP/IP network. NE-4000T-TS waits
passively to be contacted by the host computer, allowing the host to establish a connection with
the serial device. Data transmission proceeds as illustrated below.
1. The host requests a connection from the
NE-4000T-TS configured for TCP Server
Mode.
2. Once the connection is established, data
can be transmitted in both directions—
from the host to the NE-4000T-TS, and
from the NE-4000T-TS to the host.
