4.1 Overview
The EKI-1511L is designed to network-enable any RS-232 serial device, an 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-1511L features many powerful functions, such as high speed
data transfer, access-control, auto-detection of all EKI-1511L 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-1511L device server. COM port redirector, USDG TCP server mode, TCP
client 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
servers.
4.2 COM Port Redirector (Virtual COM Port)
Advantech EKI Device Configuration Utility is a serial COM port redirector that
creates 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 connected on the PC.
The Advantech redirector can create up to 255 virtual COM ports. Application to the
host can open a 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
connection to Advantech serial device servers.
Figure 4.1 Virtual COM Mode
The EKI-1511L 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 must use the same serial setting. If one serial setting within
this configuration is configured differently, the data communication will not function
correctly.
