The D VA 5718 and D VA 5724 uses standard 75 Ohm BNC connectors. We recommend
the use of high quality video cable to reduce the risk of errors due to excessive cable
attenuation.
Note. Due to the compact design of the connection plate it will be necessary to
use a connection tool to secure the BNC video connectors.
Installation
If this module was supplied as part of a system it is already installed in the rack
enclosure. If the module was supplied as a field upgrade please follow the installation
procedure below.
NOTE Observe static precautions when handling card. Please see ESD
warnings on Page 5.
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.
1. Select a slot in the card frame where the CardModule will be located.
2. Remove the blank connection panel from the rear of the rack (if fitted)
3. Install the rear connection panel using the screws supplied. Do not tighten the
screws fully
4. Slide the card module into the card frame and carefully check the CardModule
connects to the rear connection plate. The card should fit easily and should not
require excessive force to insert, if you feel any resistance, there could be
something wrong with the rear connection panel location. Do not try and force the
connection this may damage the connectors. Remove the rear connection panel
and check alignment with the CardModule.

Switch Settings
Below the switch settings for the 4-position dip-switch are defined.
Note: Dip-Switch # 4 only used for D VA 5724
Switch Function Detail
Dip Switch 1
This switch is used to enable or disable local adjustments. Set to ON enables the setting
of the other dip switches to configure the module. Set to OFF will prevent any switch
settings taking effect.
Note. The module has a microcontroller and flash ram. When this switch 1 is set to ON any
configuration settings made on the module with the dip switches will automatically be written into
flash ram and stored. (see Auto Store) The module will function normally with the switch left in the ON
position but it is recommended to set it to OFF to prevent accidental changes to the stored module
configuration if the switches are moved.
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 (D VA 5724 only)
This switch selects the channel for adjustment. ON selects channel 1, OFF selects
channel 2.

Adjustment Procedures
The modules gain/EQ settings are set using combinations of the Dip Switch and the up-
down push buttons located on the module edge (figure 3).
Setting functionality and calibration is interactive and not an implicit switch setting
process. The adjustments are made through embedded 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 Video Gain

Control System GUI
When using the module in a system with the optional LYNX control system all module
settings are available on an intuitive Windows GUI interface.
Any settings made using the control system will override any settings made locally. All
settings are stored automatically in the module flash RAM.
Screenshots below show the D VA 5724 module, the D VA 5718 looks similar, just
showing one channel.
The above screenshot shows the complete module GUI. The Device info area contains
information about the module including name and firmware revision. If used as part of a
larger system (using the LYNX central control system) the modules position and physical
location is displayed above the “locate” button.
Note. The Locate function is a tool used to quickly identify a module in larger
systems. Selecting “locate” will flash the module alarm LED yellow. (This does
not effect module operation)
The first screen displayed when the module is selected is the Main Tab this is a graphical
representation of the modules overall function and signal flow (left to right).
The area at the bottom of the screen is the error log. Any fault condition (or event) will be
time stamped and entered into the log.

D VA 5718_5724 Reference Manual. Rev 1.0
Page 16 of 16
There are a number of “Tabs” along the top of the screen which splits up the module
settings into a number of logical displays. The various GUI screens and primary functions
are described below.
Main Tab
This screen is the main interface and is presented first when the module is displayed in
the GUI.
Status: The input detection indicates if the analog video standard of a connected
signal is SDTV or HDTV. If no signal is detected the color of the input detection
will turn red.
Options:
The two top check boxes enable or disable the input clamping of the respective
input.
The two lower checkboxes enable DC coupling, if deactivated AC coupling is
active.
Gain/Equ:
The sliders provide adjustment for Gain and Cable Equalization for each channel.
The values can also be entered through the text fields below the sliders.
Clicking on the ZERO buttons (“0.000” for Gain or “0” for Equ) stets the sliders
back to Unity (zero)

D VA 5718_5724 Reference Manual. Rev 1.0
Page 17 of 16
Events Tab
The Events Tab is where the module alarming and error notifications are configured for
the module.
The GUI has an integrated error log, which is a simple text log file stored in the controller
PC. This will record an event and timestamp it. The log can be seen at the bottom of the
GUI screen and can be scrolled through using the scrolling bar.
Log in GUI Function
Events are selectable, you can chose if you want to record a particular event in the log
(or not) or configure it to only record one side of the event. (For example you might want
to log when a SDI input was removed but do not want to log when it came back). The
ON/OFF trigger can be configured for each of the available events shown in the list and is
setup using the checkboxes provided.
Event Enabled
By default all alarm conditions are activated (checked), by de-selecting a specific alarm
condition in this column you are telling the module to ignore this condition completely. It
will not color the Alarm LED, log and event in the GUI or send a SNMP trap. This is
useful if for example you never have anything connected to input 2 and want the card to
ignore this input condition completely you would simply de-select “SDI Input 2 No Input”
and it will be ignored.
SNMP Support
If the system is using a RCT 5031 Master Controller and the SNMP option is installed
then the “SNMP Trap” columns become available.
Here you can configure what events you would like to transmit a “SNMP trap” for over the
network. (This has no impact or influence over the internally error log maintained by the
LYNX control system)
(Internal LYNX error logging and external SNMP traps can be configured independently).
Note. The simulated event is part of the GUI simulator and allows us to force a
particular error condition for testing and demonstration purposes.
Note. “simulate event” is only present if simulation mode is activated. This is not
available for real modules
