PCR-1000 ActiveX™ Control Interface PCR-1000 ActiveX™ Control Interface
Note: This is a prototype control intended for use by programmers who wish to integrate the PCR1000 receiver into another application. This is not a stand-alone receiver. Additional software is required to realize the full potential of this control. Thanks to GM4JJJ for the command strings.
Installation
Download and unzip the archive file Pcr1000AX.zip into a temporary directory. Run the setup program to install the ActiveX Control on your system. The control will register itself with the operating system during the installation. To remove the control, use the uninstall option located in the same folder with the control. This will clean up a number of registry entries and other support files.
Connect the PCR1000 receiver to one of the serial communications ports.
Open the development environment (Visual C++, Visual Basic, etc.). Using the development environment controls, add the Pcr1000x control to the development environment.
Alternatively, one can use the Microsoft ActiveX Control Test Container application to examine and modify the control properties.
Once registered, the Pcr1000x ActiveX control can be used like any other ActiveX control.
Digital Signature
This is an unsigned control. You shouldn't install controls from untrusted sources. Please read the disclaimer at the bottom of the previous page. The purpose of digital signing is to verify the authenticity of controls added to your system, especially the control's origin. A digital signature might be provided with future controls. In the interim, you may contact me directly if you require further authentication.

Control Interface
ActiveX Controls are software objects having three fundamental components. They are properties, events, and methods. Properties set the configuration of the control object. Events are caused by the control object doing something. Methods are specifically what the control object can do. Changing a property can also trigger an event or invoke a method.
Error Control
Attempts to set a control property out of range are ignored. Attempting to set a boolean to a value other than 0 or 1 generates an error. Attempts to write a read-only property generates an error. Sending a bogus command to the PCR-1000 (using the SendRaw() method) can cause an unpredictable result (i.e., the control does not check raw commands for validity).
Default Settings
The control initially configures the PCR1000 to 104.1 MHz., WFM, 230 kHz. in order to receive a local broadcast station. The default properties can be changed at design time to a different configuration.
Unsupported Functions
The following tables (1-3) list the properties, methods, and events associated with the Pcr1000x ActiveX Control. Tables 4-6 list the settings for certain property settings.
