+# FG-4GT-2SX_V2.0
+
+Following is documentation for unmanaged switch marked as `FG-4GT-2SX_V2.0`.
+
+Original software is running UART on 9600 baud rate.
+
+The signal quality of UART is bad. Therefore, electrical isolation is needed for the TTL wires in some cases. A simple way to isolate them is to pinch them by fingers.
