GENERAL DESCRIPTION
The R. L. Drake DAD860 is a high quality, low noise, frequency agile, digital to analog decoder designed for receiving digital signals from off-air or CATV channels. Output of the DAD860 is baseband NTSC video and stereo audio.
The output of the DAD860 can be connected to VMM600 or VMM860 series modulators to place the programming on a specific off-air or CATV channel, or to any other device requiring baseband audio and video input such as monitors, video recorders, etc.
Parameters for the DAD860 can be set up with the DAD860 Controller Module or by front panel RS232 connection to a PC running ‘DAD860 Remote Control Software’.
The one-unit wide module can be rack mounted using the 12 position RMM12 rack mount, and is powered by the Drake PSM121 Power Supply. Up to 10 units plus the DAD860 Controller Module, or 12 units without the Controller Module can be mounted in the 12 position rack mount. If no controller is required, the RMM4 chassis and power supply may be used for up to 4 DAD860s
INSTALLATION AND MOUNTING
Install the DAD860 decoders in the RMM12 rack mounting frame. Slide each module into the frame from the front so that the mounting rails on the top and bottom of the DAD860s engage the mounting tracks on the frame. Similarly, mount the PSM121 Power Supply, again making sure that its mounting rails line up with the tracks in the frame. Apply the same mounting procedure to the DAD860 Controller.
Note that, while the sketches on this page show only DAD860s installed, any combination of DAD860s and VMM600 or VMM860 modulators could be installed. If no controller is used, up to twelve DAD and/or VMM modules can be installed per RMM12.
Plug the supplied power cable into the receptacle on the rear of the PSM121 Power Supply, and attach a connector to the POWER receptacle on the rear of each of the DAD860s, VMM modulators, and the DAD860 Controller if used.
If the DAD860 Controller is used, plug the supplied cable into the COMM receptacle on its rear panel. You will note that the other end of this cable terminates in ten three conductor female connectors. Insert one of these connectors into the LINK receptacle on each of the DAD860s installed in the rack. While these connectors can be inserted in any order, it is suggested that cables be connected to the DAD860s in numerical order from either left to right or right to left - depending on which side of the rack the DAD Controller is mounted.
Connect an RF source (off-air or CATV) to the RF IN connector on each unit and connect the VIDEO OUT and AUDIO L and R connections to the appropriate inputs of each modulator or other desired device.
Then connect the power supply power connector to the appropriate power source using the supplied line cord.
