1. Introduction
Overview
Many industrial and commercial devices are equipped with serial communication ports—RS232, RS485,
and RS422, and these serial ports typically have limited transmission distance. For instance, the
transmission distance of RS232 at the transmission rate of 9.6 kbps is 15 m and that of RS422 at the rate
of 110 kbps is 1.2 km. Examples of these serial devices include PLC controllers, card readers, display
signs, security controls, CNC controllers, and etc.
This distance constraint can be overcome by using a device called Serial-to-Ethernet server, or simply
called
Serial Server
which converts a serial communication protocol into Ethernet-compatible data
protocol. Once the data reaches any Ethernet network, its limit on transmission virtually vanishes. ATOP
Technologies’ SE5408/SE5416 Multi-Port Serial Server family is designed for this specific purpose. The
SE5408/SE5416 Multi-Port Serial Server transmits data between up-to-8-or-16 serial devices and
up-to-8-or-16 TCP/UDP ports through an Ethernet IP network. It also has two-relay output to indicate the
Ethernet link status. If the link is down, the relay output could be used to signal an operator.
All ATOP’s serial servers can be set up over Ethernet using Telnet, Web browser, Serial Console, or our
Windows utility software called, SerialManager. The SE5408/SE5416 Multi-Port Serial Server is packed in
a rugged metal housing with 19-inch rack-mount and is ideal for industrial and manufacturing installation.
Combining the SE5408/SE5416 Multi-Port Serial Server series’ internal computing resources with Linux
Software Development Kit (SDK) makes it a good solution for high-performance programmable controllers
and for time-critical and secure communication devices in industrial, telecommunication, transportation,
banking, and hospital operations.
