the eWorld

Serial Device Server System Architecture

Introduction

As the world becomes more and more wired, it is critical to manage and connect devices. Advantech offers comprehensive and cost-effective eConnectivity solutions for easy installation

and operation in critical industrial environments. These solutions meet the requirements from worldwide enterprises that need supervisory control, operator interfaces, and logging

of events and alarms via serial communication over Ethernet networks.

Wireless Serial Device Servers

Advantech wireless serial device servers EKI-1351 and EKI-1352 make it possible to

quickly connect RS-232/422/485 serial devices with PC hosts via 802.11b/g wireless

LAN networks. Functionally transparent and efﬁcient, EKI-1351 and EKI-1352 save

costs when existing hardware and software must continue to be used and also bring the

advantages of remote management and data accessibility to RS-232/422/485 devices

that cannot connect to the network.

Modbus Gateways

Advantech Modbus gateways ADAM-4572, EKI-1221, and EKI-1222 present an interface

between Modbus serial devices and computer hosts or HMIs running Modbus/TCP on

Ethernet networks. Fully compliant with Modbus/TCP, Advantech Modbus gateways offer

a convenient solution to connect existing devices or controllers running Modbus serial

protocol (Modbus/ASCII or Modbus/RTU) to an Ethernet network.

Serial to USB Converters

The industrial-grade USB to serial converters (ADAM-4561/4562, USB-4604B/4604BM)

are especially suitable for wide variety of industries such as banking, retail, factory

automation, and industrial automation. USB to serial converters provide software selectable

RS-232/422/485 ports that are compatible with all standard RS-232 or RS-422/485 serial

devices and suitable for printers, POS systems, and industrial control devices. Use them

to expand your serial ports fast, easily, and cost-effectively.

Serial Device Servers

Advantech’s serial device servers offer the easiest way to enable RS-232/422/485 serial

devices to be connected to host over Ethernet network quickly and cost-effectively.

COM port redirector makes integration of existing serial application with network-level

application an easy task. No extra programming effort is required at the host, so software

development costs can be saved. Advantech’s serial device servers are especially suitable

for remotely controlling and monitoring your serial devices via Ethernet.

Serial Device Servers

ADAM-4570 and EKI-1500 series are cost-effective serial device servers which enable

users to easily connect equipment with an RS-232/422/485 serial port to the Ethernet.

Through TCP/UDP, IP, Socket or Winsock, ADAM-4571, ADAM-4570, and EKI-1500 series

can be used for different operating systems ranging from Microsoft Windows to Linux.

Moreover, these serial device servers can use serial tunneling communications without

any intermediate host PCs and software programming to save costs and effort, allowing

two native serial devices to communicate over a network. After COM port redirector

installation, the ADAM-4570 series and EKI-1500 series serial ports will be conﬁgured as

a virtual COM port on the host. Standard serial operating calls are transparently redirected

to these serial device servers. Advantech serial device servers provide high transmission

speeds up to 921.6 kbps to offer the best performance in the industrial and ensure that the

critical application will not be harmed by data throughput. COM port redirection (Virtual

COM), TCP/UDP server/client mode, various operating mode are supported and especially

suitable for different serial applications.
