Revision 1.4 7707CVDT-1
1. OVERVIEW
The 7707CVDT series modules are VistaLINK
®
enabled, Composite Analog Video fiber transmitters for
broadcast quality video and serial data signals. The -A4 versions are also Analog Audio transmitters.
These modules accept an NTSC or PAL analog video input with up to four analog audio inputs (on the -A4
versions), perform analog to digital conversion and transmit them over a single fiber optic cable. All
7707CVDT series modules provide bi-directional transport of RS232/RS422 data on the fiber when
connected to a companion 7707CVDR module. The companion 7707CVDR series Composite Video fiber
receivers demultiplex the signals and convert them back to NTSC or PAL analog video, serial data and up
to four analog audio signals (on the –A4 versions).
The 7707CVDT and 7707CVDT-A4 occupy one card slot and can be housed in either a 1RU frame, which
will hold up to three modules, or a 3 RU frame, which will hold up to 15 modules.
Two optical interface configurations allow the user to choose the optimal function / price / performance
ratio to suit a particular application. The standard configuration transmits and receives over a single fiber.
The dual fiber (-F2) configuration is compatible with CWDM and DWDM systems and is designed to
transmit and receive over separate fibers. The optical output of the 7707CVDT is available in 1310nm,
1550nm, or any one of up to sixteen CWDM wavelengths or a multitude of DWDM wavelengths. All
versions accept 1270 nm to 1610 nm optical input signals on multi-mode or single-mode fiber (Please see
specifications, section 3, for complete information).

2.4.4. Handling and Connecting Fibers
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical
end face of a connector before making a connection.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that the user maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will
decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come with
cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the
frame that does not have a suitable I/O module. For further information about care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design section of this manual binder.

Two large LEDs on the front of the board indicate the general health of the module.
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid video and audio input signal, if a laser fault exists, or if a local input power fault
exists (i.e.: a blown fuse). The LOCAL FAULT indication can also be reported to the
frame through the FRAME STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid video or
audio input signal is present, and the laser and board power are good.
There are four small LEDs on the back side of the board that indicate the presence of serial data activity.
On the –A4 versions these LEDS also indicate the presence of audio signals above the detection level
(see section 5.4.1 for information about configuring the audio detection).
AUDIO 1 PRESENT: This Green LED indicates the presence of a valid signal on the Audio 1 input.
AUDIO 2 PRESENT: This Green LED indicates the presence of a valid signal on the Audio 2 input.
AUDIO 3 / SERIAL TX: This Green LED indicates the presence of a valid signal on the Audio 3 input or
serial TX data activity (see LEDS Menu section 5.7).
AUDIO 4 / SERIAL RX: This Green LED indicates the presence of a valid signal on the Audio 4 input or
serial RX data activity (see LEDS Menu section 5.7).
4.2. DOT-MATRIX DISPLAY
Additional signal and status monitoring and control over the card’s parameters is provided via the 4-digit
alphanumeric display located on the card edge. The card edge toggle switch is used to select whether the
user is displaying status from the card (monitoring mode) or setting control parameters for the card
(control mode). To select one of the display modes, press the pushbutton one or more times to exit the
current display mode and return to the mode select menu item (the display will show MON or SET). Press
the toggle switch to select monitor mode (MON) or control mode (SET). Once the desired mode is selected,
press the pushbutton to enter that mode. For information about setting up the module in control mode see
section 5.
When the user is in monitor mode, the toggle switch determines what data is being displayed on the
alphanumeric display. Each time the toggle switch is pressed up/down, the display advances to the
next/previous display. A message indicating what display mode is active is shown for one second. After
one second without the toggle switch being pressed, the selected display data is shown. The card edge
pushbutton is used to return to the mode select menu item. The following display messages indicate what
is being displayed. The details of the each of the displays are described in the sections 4.2.1 to 4.2.4.

5. CARD EDGE MENU SYSTEM
5.1. NAVIGATING THE MENU SYSTEM
When the user is in control mode, the toggle switch and pushbutton are used to navigate through a menu
system to set various parameters for the module. To enter the menu system, press the pushbutton one or
more times to exit the current display mode and return to the mode select menu item. The display will
show MON or SET. Press the toggle switch to select control mode (SET) and then press the pushbutton to
enter the control mode main setup menu. The user can use the toggle switch to move up and down the
list of available sub menus. Once the desired submenu name is displayed, press the pushbutton to select
the next menu level.
Once the user is in the sub menu, there will be a list of parameters to adjust. To adjust any parameter,
use the toggle switch to move up or down to the desired parameter and press the pushbutton. Using the
toggle switch, adjust the parameter to its desired value. If the parameter is a numerical value, the number
will increase the toggle switch is lifted and it will decrease the toggle switch pushed down. If the parameter
contains a list of choices, the user can cycle through the list by pressing the toggle switch in either
direction.
When the desired value is reached, depress the pushbutton. This will update the parameter to the
selected value and return to the mode select menu item (the display shows SET). To change another
parameter, press the pushbutton to enter the main menu system again and continue selecting and
adjusting other parameters.

5.3. SETTING THE VIDEO CONTROLS
5.3.1. Setting the Cable Equalization
EQ1
0
0 to 300
The EQ1 control is used to set the amount of cable equalization being
applied at the video input. It can be adjusted to compensate for various
input cable lengths to achieve a flat frequency curve. The display shows a
range of approximate cable length values expressed in meters for Belden
1694 cable or equivalent. When set to 0 the cable equalization is turned off.
5.4. SETTING THE AUDIO CONTROLS (-A4 VERSIONS ONLY)
5.4.1. Configuring Audio Presence Detection
The ADET sub menu contains 3 menu items (for each audio channel) relating to the Audio detection. The
menu items for each channel are identical so for the sake of simplicity, only the menu items for A1 channel
are shown.
DET1
OFF
ON The DET controls enable audio presence detection on each of the channels.
The LVL and DUR controls are used to detect when the audio is considered to be missing. The LVL
control sets the audio level under which the audio is considered to be missing. The audio must be under
the LVL level for the duration set by the DUR control before the audio is considered missing. When audio
is missing, the audio must be over the LVL level for 1 sec. before the audio will be considered present.
LVL1
–67 to 0
-40 The LVL control sets the audio level under which audio is considered to be
missing. This value is expressed in dBu.
DUR1
1 to 20
10 The DUR control sets the amount of time (in seconds) the audio is below
the level set by the LVL control before the audio is reported missing.
5.4.1.1. Procedure to Calibrate Audio Presence Detection
1. Supply the 7707CVDT module that is being calibrated with your plant's noisiest audio feed without any
audio program material present. This will be a baseline noise level to calibrate the audio-missing
detector.
2. Set the DUR control to 0.5 sec so that the user can see the results of adjusting the LVL parameter
without getting confused with the detection time.
3. Adjust the audio LVL control upward from its minimum value until the corresponding AUDIO PRESENT
LED on the card edge goes Off. This will be the noise floor level. Raise the LVL a few dB to make the
detector insensitive to this noise level.
4. Set the DUR control to a time appropriate to the application. This should be set to a value longer than
the worst case acceptable quiet period.
