Note: For unsolicited drivers that support Ethernet encapsulation, users will have to configure the port and the protocol
settings at the channel-level. This will allow the driver to bind to the specified port and process incoming requests from
multiple devices. An IP address is not entered at the channel since the channel will accept incoming requests from all
devices.
Ethernet Encapsulation can be used over wireless network connections such as 802.11b and CDPD packet networks,
and has been developed to support a wide range of serial devices. By using a terminal server device, users can place
RS-232 and RS-485 devices throughout the plant operations while still allowing a single localized PC to access the
remotely mounted devices. Furthermore, Ethernet Encapsulation mode allows an individual Network IP address to be
assigned to each device as needed. While using multiple terminal servers, users can access hundreds of serial devices
from a single PC.
Configuring Ethernet Encapsulation Mode
To configure Ethernet Encapsulation mode, open Channel Properties and then click on the Communications tab.
Next, click Use Ethernet Encapsulation. A driver that supports Ethernet Encapsulation will allow the Ethernet
Encapsulation mode to be selected from the Com port ID selection as shown in the image below.
Note: The server's multiple channel support allows users to have up to 16 channels on each driver protocol. This allows
users to have a channel defined to use the local PC serial port while another channel is defined to use Ethernet
Encapsulation mode.
Important: When Ethernet Encapsulation mode is selected, the serial port settings (such as baud rate, data bits and
parity) will become unavailable. This occurs because the settings will not be used in Ethernet Encapsulation mode. The
terminal server being used must, however, have its serial port configured to match the requirements of the serial
device that will be attached to the terminal server.
After the channel has been configured for Ethernet Encapsulation mode, users will need to configure the device for
