DAD860 SPECIFICATIONS

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 base-
band 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.
General Description 5
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
samemountingprocedure to the DAD860Controller.
Note that, while the sketches on this page show only
DAD860sinstalled, any combinationof DAD860s and
VMM600or VMM860 modulators could beinstalled. If
no controller is used, up to twelve DAD and/or VMM
modulescan 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
DAD860Controllerifused.
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.

8 DAD860 Setup and Programming
INTRODUCTION
The programming of each DAD860 in an RMM12
rack mounting frame is done with the DAD860
Controller, or by a PC running Drake ‘DAD860
Remote Control Software’. The following discussion
will describe the use of the DAD860 Controller. Use
of ‘DAD860 Remote Control Software’ will be
covered in documentation included with the soft-
ware.
The UNIT button on the DAD860 Controller is used
to select the unit to be programmed. The actual
programming is done via the UP, DOWN, LEFT,
RIGHT and ENTER buttons.
The chart below shows each of the menus that are
available for parameter value setup and/or viewing
for the DAD860 being programmed. Pressing the
LEFT or RIGHT arrow buttons will navigate through
these menus. You may do this without danger of
disturbing any of the current settings when not in
program mode.
As you navigate through the menus the parameter
name is listed on the top line of the display and the
current value is shown on the bottom line. For
setup purposes, it is best to progress clockwise
through the chart (use the right arrow button),
starting from the default UNIT # screen.
In the chart below shows the values that are avail-
able in each of these menus.
PROGRAMMING
To adjust and set a parameter value, enter the
program mode by pressing the center ENTER
button for approximately 3 seconds until the display
begins to flash. You are now in the program mode
and the UP and DOWN buttons will take you
through the various values for a given parameter.
Find the desired value for the selected parameter
and use the RIGHT arrow button to save that value
and progress to the next parameter, while remaining
in the program mode. (If the ENTER key is used,
the parameter value will be saved and program
mode exited.)
Proceed in this manner until all parameters have
been set to the desired value. Then press the
ENTER button to exit program mode and use the
UNIT key to proceed to the next DAD860 to be
programmed.
Pressing the LEFT arrow button while in program
mode will back up to the previous parameter without
saving the current parameter value to memory.
Once programming for a given DAD860 has been
completed, the information will be retained in the
units memory until it is reprogrammed, even when
power is removed.

ADDITIONAL MENU ITEMS
RF # - MPEG # - This menu screen allows selec-
tion of the desired channel and MPEG program
from the list saved in memory or by one of the
methods in the secondary menus described previ-
ously.
TV TYPE - Since the purpose of the DAD860 is
usuallyto provide 480i,4:3 aspect ratio video for
display as a 480i signal, choose the 4:3 setting.
MODE - Thisselection determines howthe video will
be displayed on the TV screen. One of the AFD
modes is recommended. “AFD/LTR” and “AFD/
CROP” use data that may be transmitted by the
broadcaster via the AFD (Active Format Description)
codes to automatically switch the DAD860’s output
between cropped or letterbox display to provide the
optimum viewing experience on a 4:3 TV. If no codes
are being transmitted, the aspect ratio will default to
“LTR BOX” or “CROPPED” respectively. If it is
desirableto ignore AFDcodes and forcea particular
mode, that may be done by selecting one of the

level of the left and right audio outputs. The selec-
tions are from 0 to 100. Adjust for maximum audio
levelwithout distortion. 85is the default value.

audio when multiple languages are available. The
choices are “1. ENG” (English), “2. SPA” (Spanish)
and “3. FRE” (French).
WEAK SIG - This is used to select the video output that

is either absent or too weak for successful decoding.
The choices are “NO MUTE”, and “MUTE”. If “NO
MUTE” is selected, pressing the RIGHT button will
take the user directly to the VERSION NUMBER

selected, much more pixelization can be seen at
around 15 dB SNR and the screen will go to blue
screen at around 12 dB SNR.
UNIT # - SN - This is the default screen when a
DAD860 is selected. It displays the unit number of
the selected DAD860 as well as the signal to noise
ratio (SN) of the signal being received. If no signal

instead of a signal to noise ratio.
CH PLAN - This menu allows the selection of the
type of channel plan that will be received. The
choices are “OFF AIR”, “CATV STD”, “CATV HRC”
and “CATV IRC”. Tables showing channel number
vs frequency of CATV STD and OFF AIR (broadcast
TV) channel plans are shown on pages 11 and 12
respectively.
PROGRAMMING WITH A PC
In addition to being programmed with the ‘DAD860
Controller’, the DAD860 can be programmed with a
PC running ‘DAD860 Remote Control Software’.
Connection to the PC is accomplished using a
standard RS232 serial cable connected from a
serial port on the PC to the RS232 serial port in the
front panel of the DAD860.
Details of the programming procedure are included
in the documentation supplied with the software.
Once programming is complete, the RS232 cable
may be removed from the DAD860. It is not neces-
sary to leave the PC connected after programming
is complete.
MEMORY RETENTION
Regardless of whether a DAD860 is programmed
using the ‘DAD860 Controller’ or a PC running
‘DAD860 Remote Control Software’, a DAD860 will
retain the programming even if power is removed
for prolonged periods.
POWER SUPPLY
The DAD860 requires multiple power supply volt-
ages that are all obtained from the Drake model
PSM121 power supply module. The PSM121
mounts in the RMM12 rack tray along with one to
twelve DAD860 decoders (or other similar Drake
models such as VMM600 series modulators). The
PSM121 provides +5V, +12V and GND connections
to each unit.
The PSM121 operates over a wide range of AC
input voltages from 90 VAC to 240 VAC, 50/60 Hz,
and has an 3 wire line cord receptacle. Power
consumption from the AC line will be around 60 W
withtwelveDAD860 decoders installed.Inmany
cases, the power will be below this level.
VERSION NUMBER - Thefirmwareversionnumberof
the selected DAD860 is displayed on this screen.

SERVICE INFORMATION
You may contact the R.L. DRAKE Service Department for
additional information or assistance by calling
[phone], Monday through Friday, between
8:00 A.M. and 4:00 P.M. Eastern Time, except on holidays.
You may also contact the R.L. DRAKE Service Department by
E-mail at the following address:
[email protected]
or by Telefax:
[phone].
Should you want to return your unit for service, package
the unit carefully using the original carton or other suitable
container.
Write your return address clearly on the shipping carton
and on an enclosed cover letter describing the service
required, symptoms or problems. Also include your
daytime telephone number and a copy of your proof of
purchase.
The unit will be serviced under the terms of the
R.L. DRAKE LLC Limited Warranty and returned
to you.
Red is an overnight service. Send the unit in a way that it
can be traced if we can’t verify receipt of shipment. We
suggest UPS or insured postal shipment.
If the unit is still under the original owner’s warranty,
R.L. DRAKE will pay the cost of the return shipment to
you. Our return shipping policy is that we will return it UPS
Brown if received Brown or by US Mail, it will be returned
Blue if received Blue or Red—or it will be returned
however you prefer if you furnish the return cost for the
method you select.
If the unit is out of warranty, use one of the following
methods for return shipment:
1) You designate billing to American ExPress, VISA,
MasterCard or Discover card;
2) You prepay the service charges with a personal check,
or
3) You specify some other method of return and payment.
When calling, the technician can estimate the repair
charges for you over the phone. This is another good
reason to call before sending a unit in for repair.
Typically, equipment is repaired in five to ten working days
after it arrives at R.L. DRAKE if we have all the facts. If we
must call you, it may take longer. R.L. DRAKE is not
responsible for damage caused by lightning, nonprofes-
sional alterations, “acts of God”, shipping damage, poor
storage/handling, etc. R.L. DRAKE will make note of any
shipping damage upon receipt.
You will need to send proof of purchase to receive
warranty service.Typically, a copy of the invoice from an
R.L. DRAKE dealer will suffice.The warranty is for the
original owner only and is not transferable.
IFYOU NEED TO CALL FOR HELP
Call our Customer Service/Technical Support line at
[phone] between 8:00 A.M. and 4:00 P.M.
Eastern Time, weekdays. Please have the unit’s serial
number available. We will also need to know the specifics
of any other equipment connected to the unit.
When calling, please have the unit up and running, near
the phone if possible. Our technician(s) will likely ask
certain questions to aid in diagnosis of the problem. Also,
have a voltmeter handy, if possible.

e-mail: [e-mail]
or by Telefax: [phone].
Many of the products that are sent to us for repair are in
perfect working order when we receive them. For these
units, there is a standard checkout fee that you will be
charged. Please perform whatever steps are applicable
from the installation sections of the Owner's Manual
before calling or writing—this could save unnecessary
phone charges. Please do not return the unit without
contacting R.L. DRAKE first: it is preferred to help
troubleshoot the problem over the phone (or by mail) first,
saving you both time and money.

dress, daytime phone number, and a description of the
unit’s problem.
