Wireless Sensor Network
Adding Communication Links to Devices
The next step is to add links between the base station and the other two
devices. This represents the radio communication link between the devices.
To create links, click the Link Tool icon on the toolbar. The mouse cursor
changes from a hand to a jagged line indicating the Link Tool is currently
active. Select CWB100 to indicate that it is the first device in the link. Next
drag the resulting line to the CWS655 to complete the link.
A dialog box will appear highlighting the link. Click the OK button to accept
the link.
The link is now represented on the Drawing Canvas by a line between the base
station and the CWS655.
