Constructing a Channel in Channel Designer
Similar to the Link Designer operations in JNEye’s Control Module, a channel consists of one or more
channel components between the input port (Port 1) and the output port (Port 2). After the channel
components are placed into the workspace, click Connect to connect the components. In Connect mode,
one or two connectors are shown on each component. Connect the channel components by dragging the
line from one connector to another. Two types of connections are provided in Channel Designer: Right
Angled Line and Straight Line.
The following rules of channel construction apply to the Channel Designer:
• The Input port (Port 1) has one output port or connector
• The Output port (Port 2) has one input port or connector
• A channel component has one input and one output port
• A connection between two components can be established from an output port to an input port
• An input port cannot be connected directly to an output port
A channel establishment checking algorithm runs constantly in the background, checking whether a
channel is established for channel generation. When a channel is established between an input port and
an output port, the link lines become bold. The User Interface figure above shows an established channel
link.
