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 Serial Server solution
can easy to connect to 3 TRP-C08X which support 16 Real-COM/ TCP Port by
USB cable with only one IP address.
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 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.
Serial Server supports different modes of operation allowing user to
operate the system in different environments.
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-C34H¡¦s Serial Port to a local COM Port on the
important point is that Real COM Mode allows users to continue using
RS-232/422/485 serial communications software like HyperTerminal and
Server mode, TRP-C34H Serial Server provides a unique IP: Port address
on a TCP/IP network. TRP-C34H 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¡Xat the same time.
Client mode, TRP-C34H 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-C34H 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.
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
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.
