Video
The C MX 5710 uses standard 75 Ohm BNC connectors for the analog video and
reference input connections as well as for the SDI output. We recommend the
use of high quality video cable for digital video connections to reduce the risk of
errors due to excessive cable attenuation. Max output cable lengths the module
will support are shown below.
SDTV = 250m Belden 8281 (270Mbits/s)
HDTV = 140m Belden 1694A (1.4Gbits/s)
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 7.
This module has a single width rear connection panel. Up to ten C MX 5710
modules can be accommodated in a single Series 5000 2RU rack frame.
Each Card Module is supplied with a rear connection panel and mounting
screws. Please follow the procedure below for the installation of the card module
into the Series 5000 Card Frame.
We recommend you power the rack down before installing any additional
modules into an existing card frame.
1. Select a free slot space in the card frame where the CardModule will be
located.
2. Remove the blank connection panels 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.
5. Insert and remove the CardModule a few times to ensure correct
alignment and then tighten the two screws to secure the rear connection
plate.
6. Power up the rack and check the module LED’s. Check the module is
automatically logged into the control system device tree. (It may take a
few seconds for the control system to “discover” the new module)
NOTE:The use of the optional control system is mandatory for the control and
setup of this module. If you do not have the control system, then please
contact your LYNX representative for details on how to upgrade your
installation with the LYNX control system.

Control System GUI
All LYNX CardModules support a computer interface which allows setting the
modules parameters using the simple APPolo control software GUI interface.
Access to all standard features and in some cases extended features is possible
using this interface.
NOTE:Any settings made using the control system overrides any local settings
made on the module. All settings are stored in internal flash ram and will
survive power cycles and long term storage.
Figure 7 shows the complete module GUI. The “Device Info” area across the top
contains information about the module including name and firmware revision. The
“Position” area displays the modules position and physical location. This is useful
if the device is installed as part of a larger installation.
NOTE:The Locate button (in the “Position” area) is a useful tool to quickly identify
a module in larger systems. Activating “Locate” will flash the module’s
alarm LED in yellow color (this does not affect the module’s operation in
anyway).This function will be stopped automatically (timeout).
The “Error Log” at the bottom of the screen displays an individual time stamped
message for any error or warning condition in the system. The same information
can always be found in the APPolo Control System’s textual logfiles.

Overview
The MAIN Tab (Figure 8) visualizes the module’s functionality. The audio and video
signals are presented flowing from left to right. Selections are made using onscreen
sliders, radio buttons, drop down selections and checkboxes. The screen can be
zoomed in/out using the mouse-wheel or the navigation tool in the top left corner of the
screen. When zooming closer, the contents of the individual boxes will become visible.
flexGUI path highlighting and signal patching
The flexGUI shows all current signal connections as lines (i.e. it does not show
any signal lines that are actually unused dead ends). Hovering the mouse pointer
over any such signal line will highlight the complete signal path that leads to this
point. This illustrates clearly where the particular signal is coming from. Similarly,
the downstream path is highlighted to show where this signal is going to.
To re-connect a signal (change the routing) you can think of a signal line as a
patch-cable that has to be connected to the desired source. Hovering the mouse-
pointer over a flexible signal will show a handle. Grab the handle (click-and-hold)
with the left mouse button and drag-and-drop it to the new desired source. More
details are shown below.
Figure 8: P VD 5840 MAIN Tab

C MX 5710 Reference Manual. Rev 1.0
Page 18 of 36
A/D Converter Control
The A/D converter control is divided into three tabs:
- Analog
Settings relevant for the analog video input (e.g. analog video input type
selection, Chroma, Pedestal, Hue, etc.).
- Digital
Settings for the digital video output (e.g. comb filter selection, luminance and
chrominance gain, etc.).
- Advanced
General advanced settings not specifically related to the analog input or
digital output (e.g. VBI blanking, Color Transmittion Improvement Control,
etc.).
Frame Synchronizer
The C MX 5710 provides a frame synchronizer functionality which will
synchronize the converted analog video input to an SDI output referenced to the
connected reference input.
If the module is used as a straight
forward A/D converter (i.e. the
synchronization isn’t required), the
frame synchronizer can be bypassed
(Figure 10: Frame Sync). Simply
drag & drop the signal path on the
output of the frame synchronizer
block to the straight through path.
When the frame sync is bypassed the
module is set to minimum delay
mode.
Figure 9: A/D Converter
Figure 10: Frame Sync

C MX 5710 Reference Manual. Rev 1.0
Page 19 of 36
Reference Source Selection
The reference of the C MX 5710 for the
frame sync functionality can either be
connected to the rear connection panel
or the reference input of the rack
frame.
To determine from where the module
receives the reference signal, simply
drag and drop the line either to the “Ref Board” or “Ref Rack” input node of the
flexGUI (Figure 11: Selecting Analog REF Source).
Video Processing
Each SDI output has its own Video Processor. The following description applies
to all of the SDI outputs equally (unless otherwise noted).
Aperture Correction
Horizontal aperture correction is provided for each output channel, which can be
used to sharpen or soften the video signal. (This is sometimes required for down
converted video signals as the filtering process rolls off the high frequency very
slightly). If adjusted in the positive direction this will increase sharpness, if
adjusted in the negative direction this will soften the image.
There is a check box to switch aperture correction ON and OFF. Setting the
Aperture Correction to “OFF” has the same effect as setting in the numerical
value to zero.

Clip CR/Cb Headroom
If activated all Luminance (Y) values below 64 and above 940, and all
Chrominance (Cr,CB) values below 64 and above 864 will be clipped.
Output if no input
This selection defines the behavior of the respective SDI output signal if no input
signal is present on the connected input channel. Choices are:
Off No image will be output.
Test Pattern The selected test pattern will be shown.
Test Pattern Pre-select
A wide range of patterns is provided which can be selected using the drop down
selection provided. The pre-selected pattern can explicitly be switched ON (see
below). This same pre-selected pattern will be used if the “Output if no Input”
mode is set to “Test Pattern” (see above). The following patterns are provided:
Full field Black
Full field White
Full field Yellow
Full field Cyan
Full field Green
Full field Magenta
Full field Red
Full field Blue
15% Grey (full field)
75% Color bars
75% Color bars over Red
Pathological PLL/EQ
Test Pattern Standard
The P VD 5840 can be used a standalone test. In this case, this setting can be
used to select the exact video format that shall be generated from the SDI output.
By default, the output standard will follow the last input standard. If this setting is
modified from its default, it will fall back to the default setting as soon as a regular
input standard is connected again.
Otherwise, the selection is limited to those video standards that use the exact
same framerate as the reference signal, or half or double that frame rate.
Test Pattern Enable
This checkbox simply switches on the pre-selected test Pattern. When activated,
the whole processing box will appear in yellow background color.
