5.2.1 System Active LED
A solid LED indicates that the system has power, and a blinking LED indicates data is being
received.
5.2.2 Function Active LED
The Function Active LED indicates that data is being processed by the DDPC. If the light is off
then the data is not being processed and is leaving the same as it enters. For example if the
AES Decryption mode is turned on and the Function Active LED is on, the ASI stream is being
decrypted. If the Function Active LED is off then the ASI stream is not being decrypted.
5.2.3 DVB ASI IN (Asynchronous Serial Interface)
The DVB MPEG transport stream in high-speed serial format is input on this port via a BNC-F
connector. The DVB ASI transport stream must conform to the ETSI Spec TR101891 V1.1.1
(2001 – 2002). Then the data is fed into the FPGA.
5.2.4 DVB ASI OUT (Asynchronous Serial Interface)
The DVB MPEG transport stream in high-speed serial format is output on this port via a BNC-F
connector. The DVB ASI transport stream conforms to ETSI Spec TR101891 V1.1.1 (2001 –
2002).
5.2.5 TWO RS-232 PORTS
The DDPC has two RS-232 serial ports connected to a JST SM10B-SRSS-TB 10 pin right angle
connector. The control (CNTL) port is used to directly control the DDPC. You will be able to
interact with the software GUI and down load firmware updates. The MCU shares this port
with the USB. The data (DATA) port is used to extract User Data. Table 1 shows the Two RS-
232 Connections.

5.2.6 USB
The USB-1 is used to directly control the DDPC through a USB-B connector. It will be able to
interact with the software GUI and down load firmware updates. The USB will need to be
installed into a computer. The MCU shares this port with the RS-232 control (CNTL) port. Table
2 shows the USB Connections.
