+# Arduino VISCA Controller
+
+This is a project for using an Arduino to send VISCA commands.  This is specifically tailored for interfacing with the
+Cisco TelePresence Precision series of conference cameras (specifically testing with the TTC8-02 12x zoom w/ SDI output).
+
+The TelePresence cameras have a slight quirk to controlling it over VISCA.  To get manual control over the pan/tilt/zoom
+rates the camera needs to be sent the IR disable command, otherwise all movements behave with a speed ramp as if you 
+were controlling it with an IR remote.
+
+The Arduino Shield board present in the EAGLE directory is intended to make connecting to a TelePresence camera and
+wiring I/O easier.  The shield has headers to allow for powering the Arduino off its internal voltage regulator or via
+VIN (includes header points to make swapping easy).  There is also a header to provide 12v power over the RJ45
+connection to remotely power the camera (untested).  The shield incudes an RS232 transciever so it is ready to plug into
+the camera's control port with a standard ethernet cable.
