The SDK document outlines the API specification for the WR-RCU-100 rotator controller, including the interfacing syntax and programming examples.

This makes it possible for a third-party software developer to gain complete control over the WR-RCU-100 rotator. The WR-RCU-100 API SDK provides the user with the ability to manually or automatically position the rotator in a specified direction, with an accuracy of ±0.5 degree in each of the vertical and horizontal axes.

The API SDK is implemented as 32-bit dynamic library WRRCU100API.dll. It provides object-oriented interface to control the WR-RCU-100 device.

The API is accessible in object-oriented languages, such as C++, C# and Object Pascal (Delphi) but also in non object-oriented languages, such as C.

The API can be used by any 32-bit application under Microsoft Windows 98, Me, 2000, XP, Vista and 7, and by 32-bit applications under 64-bit Microsoft Windows XP, Vista and 7.

The WRRCU100API.dll file is available as standard part of the WiNRADiO WR-RCU-100 rotator controller installer which is supplied with the rotator. The installer can be also downloaded from here.
