SerialGate White Paper
Overview
Computer becomes more efficient tool when combined with features provided by the external
equipment connected to it.
In order to connect external devices, communication protocol determined as standard is
necessary, and the most widely used method is the serial communication. Serial
communication is based on Telex communication, and nearly every computer has a serial port.
However, communication speed is slow and it is not suitable for long distance communication.
On the other hand, Ethernet enabling N:N communication in high speed is widely used for
communication method. Even though Ethernet provides convenient wiring schemes, it is more
complex and expensive than serial communication which makes it not ideal for connecting
individual device.
History of Device Server
As two methods with different purposes and characteristics coexist, Ethernet has developed
to IP network (internet). IP network overcomes the spatial limitation that was in LAN and now
supports environment where PC all over the world can be connected on network. Computers
and devices do not need to be physically connected, and with IP address they can be logically
connected over the network. In this background, the need to connect devices with serial port to
Ethernet has increased and the device that connects them over Ethernet, device server, has
emerged.

What is a Device Server?
Device Server consists of more than one Ethernet ports and multiple serial ports enables you
to easily connect any equipment with a serial port to Ethernet. Devices connected to a device
server get the same effect as they are directly connected to the Ethernet. As devices are
indirectly connected to the target computer via Ethernet connection with the help of the device
server, it provides an environment where a variety of tasks is performed more effectively.
SerialGate
SerialGate is network access equipment which transforms socket communication as well as
RS232/422/485 serial communication and modem to a Ethernet based communication.
SerialGate does not only work as a standard device server but also provides additional
features such as Portview and Com Port Redirector.

SerialGate series is made up of various models by the number of serial ports.
SG-1010 which has the basic structure of the product supports one serial port and one port
10/100Mbps Ethernet port. Based on this common configuration, there are models with more
number of serial ports up to sixteen. Each of these products supports RS232/422/485 interface
and modem allowing users to select the appropriate communication method.
