FRONT PANEL INDICATORS & CONNECTIONS
F1 - LOCK LED - This green LED lights continu-
ously when the DAD860 is locked to the selected
incoming signal. If the lock is lost, such as when no
signal or a noisy signal is present, this LED will flash
on and off continuously
F2 - LINK LED - This amber LED flashes on and off
when the particular DAD860 is selected for pro-
gramming by the DAD860 CONTROLLER or
‘DAD860 REMOTE CONTROL SOFTWARE’.
F3 - RS232 PROGRAM - This RS232 connector is
intended to attach to a PC running ‘DAD860 RE-
MOTE CONTROL SOFTWARE’ for programming
the DAD860 as an alternative to using the DAD860
CONTROLLER module.
F4 - ASI OUTPUT, BNC CONNECTOR - not shown.
This BNC connector is only provided on the DAD860A
model and is located just above the LOCK LED.
REAR PANEL CONNECTIONS
R1 - VIDEO OUT - This “F” type connector supplies
the NTSC baseband video output to a modulator or
other suitable device.
R2 - LINK - This receptacle connects to one of the
ten serial cables from the DAD860 CONTROLLER
module for programming the desired parameters
into the DAD860.
R3 - POWER - This receptacle connects to one of
the twelve power cables from the PSM121 power
supply. The cable provides +5V, +12V and GND to
each device to which it is connected.
R4 - RF IN - This “F” type connector attaches to a
CATV (QAM) or off-air (8-VSB) digital TV signal
source.
R5 & R6 - AUDIO L & R - These two RCA Phono
connectors provide left and right stereo audio output
to a modulator or other suitable device.
RMM12 INSTALLATION OF DAD860 AND DAD860A
The DAD860A draws additional current from the power
supply compared to the DAD860 model. Thus when
the DAD860A is paired with VMM series agile modu-
lators, one less DAD860A/VMM pair can be used
compared to use with the VMM600 or VMM860 fixed
modulators. Example useable combinations are:
10 DAD860A + 1 PSM121 + 2 open spaces
6 DAD860A + 6 VMM600 + 1 PSM121
5 DAD860A + 5 VMM860AG/AS + 1 PSM121
12 DAD860 + 1 PSM121
6 DAD860 + 6 VMM (fixed or agile) + 1 PSM121
Other combinations are possible. The user must refer
to the specification for each model and make sure
that total load will not exceed the PSM121 rating.
DAD860 CONTROL MODULE
The DAD860 Control Module may be used to control
either the DAD860 or DAD860A. Models may be
mixed and use a single controller.
The DAD860 Control Module is 2 units wide and thus,
if used, one pair of DAD/VMM must be replaced by
the controller. For example: one could control 10
DAD860 units but only 8 DAD860A units in one
RMM12.
RMM4 INSTALLATION OF DAD860 AND DAD860A
Any combination of DAD860, DAD860A, and VMM
series - either fixed or agile - can be mounted ‘on their
side’ in the RMM4 rack.
