EKI-1528-DR Series User Manual 34
4.1 Overview
The EKI-1528 is designed to network-enable any RS-232/422/485 serial device, and
provides industry-grade hardware and easy-to-use software to make connecting
serial devices to an Ethernet network a surprisingly simple process.
These units immediately upgrade your existing serial devices for integration into the
Internet world. The EKI-1528 features many powerful functions, such as high speed
data transfer, access-control, auto-detection of all EKI series products, and more.
After the simple installation steps to attach your network and serial device to the
appropriate connectors on the serial device servers and driver installation, you will be
able to communicate with the serial devices via its own application software and wit
the EKI serial device server. COM port redirector, USDG TCP server mode, TCP cli-
ent mode, UDP server mode, UDP client mode, RFC2217 mode are all different
methods of making a serial connection across using one or more serial device serv-
ers.
4.2 COM Port Redirector (Virtual COM Port)
Advantech EKI Device Configuration Utility is a serial COM port redirector that cre-
ates virtual COM ports and provides access to serial device connected to Advantech
serial device server. You can configure the serial device server and enable the Virtual
COM port using one integrated utility. Advantech EKI Device Configuration Utility-
allows you to configure Microsoft applications to communicate with network enabled
serial device servers as easily as if they were physically installed in or directly con-
nected on the PC.
The Advantech redirector can create up to 255 virtual COM ports. Application on the
host can open virtual COM port to access the serial device servers at the same time.
The redirector will handle each active virtual COM port as a separate TCP connec-
tion to Advantech serial device servers.
Figure 4.1 Virtual COM Mode
The EKI-1528 Series provides Multi-access function through an Ethernet connection
path, allowing a maximum of five connections to open one serial port simultaneously.
In this mode, all connections use the same serial setting. If one serial setting within
