The C6691/IRD is a high-performance integrated receiver decoder (IRD) designed for professional broadcast and satellite communication systems. Its primary function is to receive encrypted or clear digital satellite signals (DVB-S/S2) and convert them to various available formats, such as ASI, IP, or analog/digital video output.
The device is equipped with multiple descrambling functions and typically supports a universal interface (CI) slot for CAM cards to handle encrypted pay channels. In addition to basic decoding capabilities, it provides comprehensive transport stream (TS) processing, including PID filtering, reuse, and signal quality monitoring.
The C6691/IRD ENTEK Power Supply and Relay Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

In terms of operation, the C6691/IRD first uses its tuner to lock onto a specific satellite frequency and down-converts the RF signal to a digital bitstream. Then, an internal demodulator extracts the MPEG transport stream, which, if scrambled, is decrypted by the decryption engine. Finally, the processor decodes compressed data (such as H.264 or MPEG-2) into baseband video, or repackages TS packets for IP streaming transmission, while outputting telemetry data on signal-to-noise ratio and bit error rate for system health monitoring.
- The C6691/IRD card serves as the central power supply and output interface for the 6600 series rack:
- Power Distribution: Provides direct output voltage to the 6600 V2 series protection and monitoring units installed within the system rack.
- Signal Output: Routes relay outputs to the rack backplane, enabling data transmission to alarms or other external control systems for plant-wide alarms.
- Vibration Monitoring: This system is typically used in gas turbines and other high-speed rotating machinery, monitoring vibration through connected sensors such as accelerometers.
