32bits 100MHZ Ethernet Serial Converter 2 Ports TCP/IP to
UT-6602 serial communication server
dynamic IP (DHCP) and static IP
CPU: 32bits 100MHZ
Power supply adapter: DC5V/1A
The UT-6602 serial communication server, also called-terminal
server or serial server, is a converter between the asynchronous
serial port RS-232/422/485 and Ethernet, which is an independent
intelligent device with a CPU, an embedded OS and a complete TCP/IP
protocol stack. The device is used for transparent and
bidirectional data transmission between the RS-232/422/485 and
Ethernet, and for enabling the instant connection to the network of
the RS-232/422/485 serial device.
Product features: Supports both dynamic IP (DHCP) and static IP,
supports both gateway and proxy server, able to transmit data
through the Internet; Provides transparent and bidirectional data
transmission, able to convert serial port to TCP/IP without any
additional modification to the existing system made by the user;
Internally integrated protocols: ARP, IP, TCP, HTTP, ICMP, SOCKET,
UDP; Full English interface for all programs, wizards are easy to
use even for new computer users.
☆ English menus of configuration interface with the various
operation modes, able to meet the application demand of different
☆ Virtual COM drive software for Windows;
☆ Flexible and reasonable Fixedtty working scheme under UNIX;
☆ 1, 2, 4, 8, 16, or 32 serial ports to connect the various serial
devices, including terminals, Modems, barcode machines, cash
receivers, ISDNs, terminal adapters, serial printers and PCs, etc.,
able to support the remote control function;
☆ Reset key is provided for the force reset after a system crash;
☆ A 10/10M self-adaptive Ethernet port with possibility of manual
☆ Complete signal is provided for each serial port, including DCD,
RXD, TXD, DTR, DSR, TRS, CTS, GND;
☆ Powerful whole performance with the embedded 100M 32bit CPU and
☆ Independent indicator for each network port and serial port for
convenient indication of working status;
★ Supported protocols include ARP, IP, ICMP, UDP, TCP, PPP, HTTP,
TELNET, DNS, DHCP, PAP, CHAP, etc.
★ Supports extended serial port mode under Windows
Complete extended serial port (com) drive based on the Windows
platform, and simple and easy-to-use management programs under the
Windows platform. Up to 1024 serial ports under the
WindowsNT/Windows2000/WindowsXP, with each serial port of the
UT-6602 serial server to be mapped as the local COM port of the
Windows host PC. Operation of these ports is similar to operation
of the local COM ports on the host, plus, any existing software or
communication module of the original device can be used directly
without any change.
★ Supports the UNIX host login mode
The present mode is used by the terminal device to login to the
Linux/Unix host, where each serial port supports up to 8 virtual
displays. All the displays support both the Telnet or Fixtty login,
and can choose to login a different host or the same host.
Allows communication with different hosts using the same terminal,
enabling the single user, single terminal and multi- mission
operation. The Fixedtty drive is provided for SCO
Unix/Linux/Unixware under fixed port mode (Fixtty). No extra
configuration work is required on the host, except the installation
of the drive program. All the configuration is done on the terminal
server, through this way the cleaness of the host system is ensured
and the operation of the terminal server won’t be affected by other
In addition, any name started with “tty” can be assigned to each
login terminal by the user under the fixed port mode, which is more
convenient for management and easier for troubleshooting.
★ Supports PPP serial mode
All the ports of the UT-6602 serial server support the PPP
protocol, and can be used other as a PPP server end or as a client
end after configuration.
★ Features routing function
Allows configuration of multiple static routes inside the server.
★ Supports DNS for domain service
Allows query of the required IP address for analysis when
connecting a machine.
★ Supports ARP
The UT-6602 serial server supports the standard ARP protocol.
★ Parameters of configuration of terminal server
Connection to the terminal server through the web to perform the
configuration, by doing this the user can use the UT-6602 serial
server in work conveniently.
★ Supports software update function
The UT-6602 serial server supports free software update to protect
the investment of the user.
★ Supports status monitoring
Not only indicators are provided on the UT-6602 serial server for
the analysis of the working status of the server, but also
statistics of the input/output data of each network port and serial
port, as well as various information, are provided for the analysis
of the user.
★ Supports MODEM connection
The UT-6602 serial server supports MODEM plug in/out.
The UT-6602 serial server adopts the following security schemes to
ensure the safe use of the product by the user.
☆ Allows setting a server administrator password, where only the
system administrator is allowed to manage the terminal server,
eliminating the arbitrary modification to the UT-6602 serial server
by unauthorized personnel. Thus the security of the configuration
of the UT-6602 serial server is ensured.
☆ Possible to limit the host name the port is about to login, so
host users without registration will not be able to access the
server, so the secure access to the server is ensured.
☆ Since the UT-6602 serial server is connected to network during
operation, the server is PPP certified (support PAP and CHAP
certification) to ensure the security of the server during the
☆ Possible to pose limits to the hosts or network segments allowed
to access the server, the unauthorized objects not registered in
the hosts list and the network segment will not be able to pass the
network access server;
The ex-factory IP address of the UT-6602 serial server is
192.168.1.125, and the subnet mask is 255.255.255.0
