ASI/SDI via BNC serial cable, and/or LVDS/LVTTL via 50-pin connector, computer communications through two RS-232 ports, and can be programmed for custom applications. The DDPC is designed to fit one of the slots of the GMS Messenger Smart Receiver (MSR) or stand-alone. -
Page 6: System Overview
For example, if connected to a GPS the transmitter location could be known at any time. Without disrupting the video stream, the DDPC will extract the User Data and send it to a computer through a RS232 port. All connections to the DDPC are located on the back panel. -

Page 12: Hardware Overview
Hardware Overview The DDPC is designed to fit in one slot of the MSR or in an optional external 4”x3”x1” enclosure. All user interface connectors (RS-232, USB, ASI in/out and 50 pin LVDS/LVTTL) and two led indicators (System Active and Function Active) are located on the rear of the DDPC unit panel. -
Page 13: Ddpc Connection Diagram
The DDPC fits into any slot in the MSR except #1 if diversity tuners are loaded. The MSR’s “switched 12 VDC” must be turned on for the card slot that the DDPC is in. The MSR can talk to the DDPC through the 80-pin connector via I2C port on the connector. -
Page 14: System Active Led
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. -

Page 19: Function Aes Decryption
Decryption key must be reloaded every time it is powered off. This is for higher security. AES, Store the key in DDP mode: This mode does AES Decryption and the DDPC remembers the Decryption key so when the DDPC is powered on it will come up working. -
