Crestron Active CNX Software

See the Visual Basic examples in the Crestron e-control™ SDK for examples using

this control with the CNMSX control system and a CEN-IO device.

Properties

To get and set the components properties right click the ActiveCNX icon and select

Properties. The “Property Pages” dialog appears. It permits the programmer to set

initial values

NOTE: These property values can always be set programmatically as well.

Property Pages Dialog Box

GatewayIPAddress - This property is the IP address of the PC that is running the

CNX Gateway software. If the configuration is a local server then this property is

need not be set, since it defaults to the local host (127.0.0.1). For distributed

applications there maybe one server and many PC clients (ActiveCNX controls)

connecting to the CNX Gateway from different places on the network (or Internet).

In this case, the CNX Gateway IP address needs to be set by typing the new value in

the property sheet or dynamically by setting the GatewayIPAddress Property.

Dynamic - This property is only used with CEN devices, therefore this property is

ignored if used with the CNMSX control system. If this value is set to TRUE, a

dynamic entry is added into the device's IP ID table. Otherwise, to get feedback to

the application, a static entry must be manually added to the IP table in the CEN

device (refer to the latest revision of the specific CEN documentation). The default

value of this property is FALSE.

There is only one connection per ActiveCNX Control so if connect is called the

second time Disconnect() is automatically called and Connect() is issued again with

the new properties. For multiple connections per application, simply drop multiple

ActiveCNX controls on the form.

Methods

The general procedure for using the components methods are to first call Connect()

to start the control session and when complete call Disconnect(). Between Connect()

and Disconnect() any combination of the sending and receiving the three data types

can be used. At anytime during development if the programmer needs to see
