GENERAL DESCRIPTION

The R. L. Drake DAD860 and DAD860A are high

quality, low noise, frequency agile, digital to analog

decoders designed for receiving digital signals from

off-air or CATV channels. Output of the DAD860 is

baseband NTSC video and stereo audio. The

DAD860A, only, has these NTSC outputs plus an

additional ASI output containing the entire demodu-

lated transport stream for the tuned RF channel (all

programs included).

The NTSC output of a DAD860 or DAD860A can be

connected to VMM series modulators to place the

programming on an off-air or CATV channel, or to any

other device requiring baseband audio and video input.

INSTALLATION AND MOUNTING

Install the 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 DAD 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 drawings on this page show only

DAD860s installed, various combinations of

DAD860(A)s and VMM600 or VMM860 modulators

could be installed in the same RMM12 or RMM4.

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.

PROGRAM

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. DAD860As require more current

from the power supply and thus require the above

capacity to be reduced by two.

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 termi-

nates in ten three conductor female connectors.

Insert one of these connectors into the LINK recep-

tacle 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 appro-

priate 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.
