<Text>The &lt;i&gt;&lt;b&gt;Acquisition Client&lt;/b&gt;&lt;/i&gt; box
receives data from the OpenViBE acquisition
server. You should have the OpenViBE
acquisition server started and acquiring to
let this scenario work correctly. In case
of connection errors, you should read a
message in the console.</Text>
