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, LAN enabling N:N communication in high speed is widely used for

communication method. Even though LAN 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, LAN 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 LAN has increased and the device that connects them over LAN,

device server, has emerged.

What is a Device Server?

Device Server consists of more than one LAN 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 LAN. As devices are

indirectly connected to the target computer via LAN 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 LAN-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 two 10/100Mbps

LAN ports. 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.
