6 Introduction
See the OpenLDV 4.0 ReadMe document for updates to the OpenLDV driver
documentation.
To develop an OpenLDV application or xDriver extension, install the OpenLDV
SDK (OpenLDV400-SDK.exe) in addition to the OpenLDV driver. The
OpenLDV SDK contains documentation, source files, and several examples,
which you can use when developing your own OpenLDV application or xDriver
extension.
See the OpenLDV SDK 4.0 ReadMe document for updates to the OpenLDV SDK
documentation.
Installing the OpenLDV Driver
To install and use the OpenLDV driver, perform the following steps:
1. Download the OpenLDV Driver OpenLDV400.exe file from Echelon’s
Web site at www.echelon.com/downloads
.
2. Double-click the OpenLDV400.exe file to begin the OpenLDV driver
installation. The OpenLDV driver installer window opens.
3. Follow the installation dialogs to install the OpenLDV driver onto your
computer.
If you are using a SmartServer or i.LON network interface:
1. Use the L
ONWORKS Interfaces application in the Windows Control Panel
to specify the IP network addresses of the SmartServer or i.LON network
interface. See the online help for the L
ONWORKS Interfaces application
for information about how to use it.
2. If you are using a SmartServer or i.LON network interface and you are
developing a custom xDriver profile, use the xDriver Profile Editor in the
OpenLDV program folder to configure an xDriver profile for use with
your OpenLDV application. For more information on the xDriver Profile
Editor, see Chapter 5, Using the xDriver Default Profile, on page 93.
3. See the installation instructions for your network interface for any
additional instructions for configuring the network interface.
Installing the OpenLDV SDK
To install and use the OpenLDV SDK, perform the following steps:
1. Download and install the OpenLDV driver, as described in Installing the
OpenLDV Driver.
2. Download the OpenLDV SDK OpenLDV400-SDK.exe file from
Echelon’s Web site at www.echelon.com/downloads
.
3. Double-click the OpenLDV400-SDK.exe file to begin the OpenLDV SDK
installation. The OpenLDV SDK installer window opens.
4. Follow the installation dialogs to install the OpenLDV SDK onto your
computer.
5. You can now use the OpenLDV SDK to write applications that use the
OpenLDV API or create xDriver extensions. For information about the
OpenLDV API, see Chapter 2, Using the OpenLDV API, on page 9. For
