Getting Started
Packaging
The shipping carton and packaging materials
provide protection for the module during transit.
Please retain the shipping cartons in case
subsequent shipping of the product becomes
necessary.
Product Description
The D VA 5120 L is a high quality analog video
distribution amplifier designed primarily for
broadcast and professional applications.
Flexible configurations allow the module to be used
in dual 1 to 4 applications or single channel 1 to 8
applications. Independent gain and equalization
adjustments are provided for each channel. The
module is microprocessor controlled and all settings
are stored in internal flash ram. Presence detection
is provided via status LED’s and a front side alarm
LED is also provided. Optional remote control /
status reporting and SNMP error reporting is
supported when using the LYNX central control
system. The LYNX control system is set up to do this
most of the time
The D VA 5120 L is part of the 5000 series of
CardModules, which offer high quality, modularity
and flexibility in a small form factor ideal for
applications where space is at a premium.
CardModules are installed in the series 5000 card
frame that can accommodate up to 10
CardModules. All modules are hot swappable and
Options include full redundant power and a range
of controller options.

Functional Diagram
Figure 1 below is the basic functional diagram for
the D VA 5120 L CardModule.
Figure 1- D VA 5120 L Functional Diagram
Module Layout
Figure 2 shows the physical layout of the D VA 5120
L CardModule. Video I/O is made on the supplied
connection plate through standard BNC video
connectors. Module configuration is set via a small
dip-switch and a up-down push button located on
the front of the PCB. When used in single mode
(1x1:6) IN 1 is used as the input signal.

Caution
Use static precautions when handling the
PCB. Static discharge could result in serious
damage to the module.

Connections
Video Connections
The D VA 5120 L MiniModule is configured with
standard 75 Ohm BNC connectors. Connection is
self-explanatory. We recommend the use of high
quality video cables to reduce the risk of
interference or errors due to excessive cable
attenuation.
Note. Due to the compact design of the rear
connection plate it will be necessary to use a
connection tool to secure the BNC video
connectors to the module.

Installation
Caution
The CardModule is shipped in a
protective anti-static bag. Please take
suitable precautions to avoid static
discharge onto any part of the PCB or
components when handling module or
serious damage could result.
Each Card Module is supplied with a rear
connection panel and two mounting screws.
Please follow the following procedure for
installation of the card module into the Series 5000
Card Frame.
a) Select a slot in the card frame where the
CardModule will be located
b) Remove the blank connection panel from the
rear of the rack (if fitted)
c) Install the rear connection panel using the
screws supplied. Do not tighten the screws fully
d) Slide the card module into the card frame and
carefully check the CardModule easily
connects to the rear connection plate. The
card should fit easily and should not require
excessive force to insert, if you feel high
resistance, there could be something wrong
with the rear connection panel location. Do not
try and force the connection. Remove the rear
connection panel and check alignment with
the CardModule.
e) Insert and remove the CardModule a few times
to ensure correct alignment and then tighten
the two screws to secure the rear connection
plate

Switch Function Detail
The switches are used as part of an adjustment
procedure and setting is not an implicit process.
Please refer to the alignment procedure section for
details on how to use the switches to set up the
module. The information below simply describes
function.
Dip Switch 1
This switch sets the configuration of the module. ON
sets single 1:3 mode. OFF sets dual 1:6 mode.
Dip Switch 2
This switch selects the parameter for adjustment
using the module push buttons. ON selects gain,
OFF selects equalization.
Dip Switch 3
This switch sets unity gain / equalization for the
module. ON selects unity, OFF allows for
adjustment.
Dip Switch 4
This switch selects the channel for adjustment. ON
selects channel 1, OFF selects channel 2.
Factory Preset Condition
The D VA 5120 L is delivered preset for the following
mode of operation:
Mode 2 x 1:3
Setting Unity Gain, Unity Equalization
Input coupling DC
Input clamp ON
If this is the mode of operation required, then no
adjustments are necessary.

Link Settings
Input coupling
It is possible to select AC or DC input coupling for
each input channel. This is done using physical links
on the card, and the card will need to be removed
from the card frame for changes to be made*.
Figure 3 shows the locations and settings
Input Clamp
The input clamping can be turned on or off for
each input channel. This is done using physical links
on the card and the card will need to be removed
from the card frame for changes to be made*.
Figure 3 shows the locations and settings.
Note.When set to single 1 > 6 mode of operation
only channel 1 is used.
*Note. It is not necessary to power down the frame
to remove the card. All Series 5000 Card Modules
can be hot plugged / unplugged.

Adjustment Procedures
The modules configuration and gain/EQ settings
are set using combinations of the Dip Switch and
the up-down push button located on the module
edge.
Setting functionality and calibration is interactive
and not an implicit switch setting process. The
adjustments are made through imbedded micro-
controller and settings stored on internal flash ram.
To simplify the configuration and setting of the
module a series of procedures has been defined to
make setting the module easier. These are:
•Set Dual 1:3 or 1:6 Mode
•Set Video Gain
•Set Equalization
•Set Unity Gain
•Set Unity Equalization
These procedures capture most things you would
need to change or set on the module.

Set Dual 1:3 or 1:6 mode
The D VA 5120 L module can be set to one of two
preset modes of operation.
Dual 1:3 Mode. This is a simple 2 x 1 to 3 video
amplifier. Independent left and right channels
passed through the amplifier providing four outputs
for each input channel.
Single 1:6 Mode. This is a simple 1 x 1 to 6 Video
amplifier. The signal on the IN 1 input channel is
passed through the amplifier providing eight
outputs.
Use this procedure to select 2 x 1 to 3 or 1 x 1 to 6
modes of operation.
1. Set Switch 1 to OFF for 1:6 mode* or ON for dual
1:3 mode
2. If 10 seconds pass with no further adjustment
both channel status LEDS will flash yellow four
times. This confirms setting has been written into
flash ram and stored.
* When in 1: 6 mode the IN 2 channel indicator will go out.
