RCB module interface signal：

1)FPC_Main interface
FPC_Main is a 26PIN flat cable soft cable interface，It can be used as a connection path to transfer video stream/data between the RCB COFDM modulation module and the front-end video encoding module or data module1。FPC_Main interface signals include MCU serial port(For debugging/configuring modulation parameters)、SWD、SPI、FPGA JTAG、Ethernet(Video/digital signal transmission)、power supply、reset signal etc.。

2)FPC_CON interface
The FPC_CON interface is a 14PIN flat cable soft cable interface，Signals include 3.3V power output、IIC、SPI、UART、GPIO and other signals。The FPC_CON interface can be used to connect an external control panel。
