+Remote Control
+#################
+
+Some Ephys Socket settings can be modified via the GUI's built-in HTTP server. Commands are sent as "config messages" to the Ephys Socket node.
+
+.. note::
+
+    Parameters cannot be modified while acquisition is running, nor can they be modified if the port is connected. To change any settings remotely, the port must be disconnected in the GUI
+
+The following commands are available:
+
+1. :code:`ES INFO` : returns a JSON string containing information about all available variables (i.e., scale, offset, port, and frequency)
+2. :code:`ES SCALE <data_scale>` : set the data scale
+3. :code:`ES OFFSET <data_offset>` : set the data offset
+4. :code:`ES PORT <port>` : set the port number
+5. :code:`ES FREQUENCY <sample_rate>` : set the sampling frequency
