1. Introduction
TRP-C34R
4 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.
By specifying the IP address and the TCP Port number, a host computer can access different
Serial Devices such as Serial Modems, Serial Thermometers, Magnetic Card Readers,
Barcode Scanners, 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-C34R Serial Server 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-C34R Serial Server supports different modes of operation allowing user to operate the
system in different environments
.
Virtual COM Mode
.
TRP-C34R Serial Server 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), WIN 8(32/64 bit),The driver establishes a transparent connection between
host and serial device by mapping the IP: Port Number of the TRP-C34R’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-C34R Serial Server provides a unique IP: Port address on a
TCP/IP network. TRP-C34R Serial Server 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-C34R Serial Server can actively establish a TCP connection to a
pre-defined host computer when serial data arrives. After the data has been transferred,
TRP-C34R Serial Server 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.
