          Q04. In Serial Mode, does SOMO-14D need to be communicated Serially through the Com port?

          Ans. No, there is no UART type Rx/Tx or Serial Com port on the SOMO-14D Module. Serial mode here means, the data and clock are latched serially in to the Data and Clock pins of the module. You can use Digital IOs of your controller to generate the DATA and Clock signals to control the SOMO-14D in Serial mode.
