1. Introduction
TRP-C34H 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, TRP-C34H solution can easy
to connect to 3 TRP-C08X which support 16 Real-COM/ TCP Port by USB cable with only one IP
address.
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-C34H 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-C34H supports different modes of operation allowing user to operate the system in
different environments.
Real COM Mode.
TRP-C34H 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-C34H’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-C34H provides a unique IP: Port address on a TCP/IP network.
TRP-C34H 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-C34H can actively establish a TCP connection to a pre-defined host
computer when serial data arrives. After the data has been transferred, TRP-C34H 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.

3
UDP Mode.
Compared to TCP communication, UDP is faster and more efficient. In UDP mode, you can
multicast data from the serial device to multiple host computers, and the serial device can also
receive data from multiple host computers, making this mode ideal for message display
applications.
TRP-C34H hardware support wide range power input , the 4 RS422/485 interface with surge,
over current ,over voltage protection, the RS485 interface built-in hardware decoder ensure
RS485 data without lost, Specify hardware can ensure on line RS485 device working fine.
The TRP-C34H has four synchronous D SUB 9 pin serial port for RS232 connection and 4 screw
terminal block for RS422/485 and power connection. The Ethernet port support Auto-MDIX and
Auto-select 10/100MB.
When TRP-C34H working at unstable voltage industrial environment, the hardware circuit
detection can prevent the power fail cause of the boot fail and Re-Boot.
