Chapter 1 General data on UT-66XX series serial server
a) Product introduction
The UT-66XX series serial communication server, also called - terminal server or serial server, is a
converter between the asynchronous serial port RS232/422/485 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 RS232/422/485 and Ethernet, and
for enabling the instant connection to the network of the RS232/422/485 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.
UT-66XX series serial server includes the following models

☆Independent indicator for each network port and serial port for convenient indication of working status;
Software features
★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-66XX series 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 accidental actions.
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-66XX series 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-66XX series 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-66XX series serial server in work conveniently.
★Supports software update function
The UT-66XX series serial server supports free software update to protect the investment of the
user.
★Supports status monitoring
Not only indicators are provided on the UT-66XX series 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-66XX series serial server supports MODEM plug in/out.

Security features
The UT-66XX series 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-66XX series serial server
by unauthorized personnel. Thus the security of the configuration of the UT-66XX series 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☆-66XX series 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 network
access;
☆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-66XX series serial server is 192.168.1.125, and the subnet mask is
255.255.255.0

c) Working mode
TCP realport (TCP/IP virtual serial mode)
TCP realport works in Windows environment to map ports of a serial server as virtual COM ports of the
local host through drive program, enabling the COM based upper end software to use the serial ports just
like real local COM ports without any modification of the software. The drive program supports an
extension of COM1024 for the most. Moreover, each independent port supports multiple sessions (up to
6 connections), which makes the monitoring of the serial devices more flexible and more convenient. In
addition, the multiple connections resource can be used as a connection backup.
