1. Introduction
TRP-C34X RS232/422/485 Serial Server provides a transparent way of connecting Serial
devices over Ethernet. It can transmit data between the Serial and Ethernet interfaces bi-
directionally. To establish automatic or remote data acquisition, TRP-C34X S
erial Server also
provides 3KV optical isolation and surge protection to protect system from ground loops and
destructive.
By specifying the IP address and the TCP Port number, a host computer can access different
Serial Devices such as Serial Thermometers, Magnetic CNC Controller, Elevator, Data
Acquisition Systems, POS Terminals, Industrial PCs etc., over the Network, you can centralize
Serial Device management and distribute the management to different hosts at the same time.
TRP-C34X makes possible to access distant Serial Devices over Network as if they were
directly connected to the Standard COM Port of a Personal Computer.
TRP-C34X supports different modes of operation allowing user to operate the system in
different environments .
Real COM Mode .
TRP-C34X comes equipped with COM drivers that work with Operating Systems WIN 32bit
XP /Vista/2003Server/2008 Server (32-bit & 64-bit), 2000 Server OS, Win 7 (32-bit & 64-bit),
The driver establishes a transparent connection between host and serial device by mapping the
IP: Port Number of the TRP-C34X’s Serial Port to a local COM Port on the host computer.
The important point is that Real COM Mode allows users to continue using RS-232/422/485
serial communications software like HyperTerminal and similar applications.
TCP Server Mode.
In TCP Server mode, TRP-C34X provides a unique IP: Port address on a TCP/IP network. TRP-
C34X waits passively to be contacted by the host computer, allowing the host computer to
establish a connection with and get data from the serial device. This operating mode supports
up to 4 simultaneous connections, so that multiple hosts can collect data from the same serial
device—at the same time.
TCP Client Mode .
In TCP Client mode, TRP-C34X can actively establish a TCP connection to a pre-defined host
computer when serial data arrives. After the data has been transferred, TRP-C34X can
automatically disconnect from the host computer by using the TCP alive check time or Inactivity
time settings. This Operating Mode supports establishing the TCP connection up to 4
Destination Hosts.
