ActiveCNX
ActiveX controls are special “applications”, similar to Java applets, which can be
plugged into Web pages or other PC-based programs to extend functionality. They are
designed to be small, precompiled, modular and reusable. Microsoft, as well as
hundreds of third-party developers, create and market ActiveX controls. Many
software development tools support ActiveX controls, including Visual Basic, Visual
C++, PowerBuilder, Java, and Delphi, so that most programmers can create ActiveX
controls if their application warrants it.
Crestron developed its own ActiveX control, called
ActiveCNX
, to enable any
software program that supports ActiveX technology to be used as an interface to e-
Control. Crestron also incorporates ActiveCNX in its e-Control Power Applications,
such as e-Outlook and e-PowerPoint. The control, together with its routines and
documentation, are contained in the Crestron SDK.
Like Crestron’s Java components, an ActiveCNX control has the capability to connect
to the e-Control gateway; send and receive digital, analog, and serial signals, using the
same “join number” scheme as a touchpanel.
Each ActiveCNX control in a PC application must have a corresponding
ActiveCNX
Interface
symbol defined in the SIMPL Windows program. The ActiveCNX Interface
symbol is found in the Ethernet Modules folder of the Device Library. It must be
assigned an IP ID and IP address; both the IP ID and IP address must be entered into
the IP Table of the control system.
The Ethernet Modules folder also includes interface symbols for Crestron’s
e-Control Power Applications; for example, there’s an e-PowerPoint Interface and an
e-Outlook Interface. All of these symbols are based on the ActiveCNX Interface
symbol.
The ActiveCNX Interface symbol detail is defined in the same way as a touchpanel.
That is, join numbers defined in the ActiveCNX control are mapped to signals on the
symbol. The signals on the output side trigger actions or other logic in the program,
while the signals on the input side can be sent as feedback to the ActiveCNX control.
