The Drake DAD860 manual covers the setup and operation of the digital to analog decoder, detailing how it receives digital signals from ATSC broadcast stations or clear QAM CATV systems and decodes them to analog NTSC video and stereo audio. It also provides troubleshooting information, including programming the device using a controller module or a PC with Drake DAD860 Control Software, and outlines various installation options and potential applications for different environments.
Manual Overview
The Drake DAD860 manual provides detailed instructions on troubleshooting, diagnostics, and adjustments for the digital to analog decoder. For troubleshooting, the manual outlines a flow that begins with checking power supply connections, ensuring the RS232 interface is properly connected for programming, and verifying input signal levels are within the recommended range (-26 to +30 dBmV for 8VSB, -15 to +15 dBmV for 64 QAM, and -12 to +15 dBmV for 256QAM). Error codes and diagnostics can be accessed via the DAD860 Controller or a connected PC using the Drake DAD860 Control Software. Calibration involves adjusting audio output levels and selecting the appropriate aspect ratio for video output. Board-level guidance includes ensuring proper installation within the Drake RMM4 or RMM12 chassis for power supply and connectivity. The manual also details the configuration for different audio outputs, including mono, stereo, and SAP, requiring specific modulators like the VMM860AG or VMM860AS for distribution.
Quick Issues Covered
- Diagnose RS232 communication errors with DAD860 Control Software.
- Calibrate audio output levels via user adjustments.
- Troubleshoot power-up failures with RMM4 or PSM121 power supplies.
Overview
