2. INSTALLATION
The 7707CVR comes with a companion rear plate that has two BNC connectors, one twelve pin terminal
header with removable terminal block and one SC/PC, SC/PC with cover flap, ST/PC or FC/PC optical
connector. For information on mounting the rear plate and inserting the module into the frame see the
7700FR chapter section 3.
Figure 4: 7707CVR Rear Panels
OPTICAL INPUT SC/PC, SC/PC with cover flap, ST/PC or FC/PC female connector. This wide range
input accepts optical wavelengths of 1310nm accommodating standard or 1270nm to 1610nm
CWDM transmission schemes.
"
Do not hook up the 7707CVT series DWDM cards and any 7707CVR series cards
directly with a short fiber optic cable. The 7707CVT series DWDM card
produces +7dBm of power which will damage the receiver if connected directly.
7707CVR-4 Revision 1.7

7700 MultiFrame Manual
7707CVR Composite Video and Analog Audio Fiber Receiver
"
Do not hook up the 7707CVT series cards that output more than -7dBm of power
(see 7707CVT series specifications for output power of various laser types) and
7707CVR series high sensitivity (-H versions) receiver cards directly with a
short fiber optic cable. The 7707CVT series cards that produce more than -
7dBm of power will damage the receiver if connected directly.
ANALOG VIDEO OUTPUTS On the 7707CVR there are two composite analog video outputs. On the
7707CVR-2 there is one output for each video channel. Each output can have cable pre-
emphasis applied independently. (See section 5.3.3 for information on setting the desired pre-
emphasis)
WAUDIO Complex audio output
ANALOG AUDIO OUT Balanced analog audio outputs for 4 channels. Each output (+, -, GND) is
on three of twelve pins on the twelve pin terminal header.
2.1. CARE AND HANDLING OF OPTICAL FIBER
"
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 you 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 chapter in the front of the binder.

7700 MultiFrame Manual
7707CVR Composite Video and Analog Audio Fiber Receiver
5.4.3. 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 (1 to 4) 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 controls (1 to 4) set the audio level under which audio is
considered to be missing. This value is expressed in dBu
DUR1
1 to 20
10
The DUR controls (1 to 4) set the amount of time (in seconds) the audio is
below the level set by the LVL control before the audio is considered
missing.
5.4.3.1. Procedure to Calibrate Audio Presence Detection
1. Supply the 7707CVT module that is connected to the 7707CVR module 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 you 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

6. CARD EDGE CONTROLS
The 7707CVT is equipped with a three position, return to center toggle switch is used to select the various
card-edge displays and menu items and is also used in conjunction with a momentary pushbutton to select
some sub-items of the menu system. See sections 4.2 and 5 for information about the card edge displays
and menu system.
6.1. MONITORING THE AUDIO
A stereo headphone jack located at the front of the module is used to monitor the individual audio channel
pairs. The AJCK menu item is used to select the audio channels currently being monitored. (See section
4.2.1) The monitoring volume level can be adjusted but turning the level potentiometer located beside the
headphone jack.
7. JUMPERS
Several jumpers, located at the front of the module are used to preset various operating modes. Figure 5
shows the location of the card edge controls, status indicators and jumpers.

7.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J4 determines whether local faults (as shown by the Local Fault indicator)
will be connected to the 7700FR frame's global status bus.
FRAME STATUS To monitor faults on this module with the frame status indicators (on the Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this jumper in the
On position. (Default)
When this jumper is installed in the Off position local faults on this module will not be
monitored.
7.2. SELECTING WHETHER MODULE WILL BE CONTROLLED FROM THE
LOCAL CONTROLS OR THROUGH THE VISTALINKTM INTERFACE
The MASTER jumper J6 selects whether the module will be controlled from the local user controls or
through the VistaLINKTM interface.
MASTER When this jumper is installed in the LOCAL position, the card functions are controlled through
the local jumpers.
When this jumper is installed in the REMOTE position, the card functions are controlled through
the VistaLINKTM interface.
7.3. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE The UPGRADE jumper J5 is used when firmware upgrades are being done to the module.
For normal operation it should be installed in the RUN position. See the Upgrading Firmware
chapter of this manual for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the UPGRADE
jumper into the UPGD position. Install the Upgrade cable provided (located in the vinyl pouch
in the front of this manual) onto the SERIAL header at the card edge. Re-install the module
into the frame. Run the upgrade as described in the Upgrading Firmware section of this
manual. Once the upgrade is completed, remove the module from the frame, move the
UPGRADE jumper into the RUN position, remove the upgrade cable and re-install the module.
The module is now ready for normal operation.
8. VISTALINK™ REMOTE MONITORING/CONTROL
8.1. WHAT IS VISTALINK™?
VistaLINK™ is Evertz’s remote monitoring and control capability over an Ethernet network using Simple
Network Management Protocol (SNMP). SNMP is a standard computer network protocol that enables
different devices sharing the same network to communicate with each other. For monitoring there needs
to be a detecting device that automatically reports all errors to a central alarm and error logging station.
We also need to be able to interrogate individual detector devices from the central station to determine the
status of individual channels. Finally, we need to be able to configure devices in the network from the
central station and receive feedback that the configuration has been carried out.

7700 MultiFrame Manual
7707CVR Composite Video and Analog Audio Fiber Receiver
There are 3 components of SNMP:
1. An SNMP manager also known as a Network Management System (NMS) is a computer running
special software that communicates with the devices in the network. Evertz VistaLINK™ Pro Manager
graphical user interface (GUI), third party or custom manager software may be used to monitor and
control Evertz VistaLINK™ enabled fiber optic products.
2. Managed devices (such as 7707VAT and 7707CVR cards), each with a unique address (OID),
communicate with the NMS through an SNMP Agent. Evertz VistaLINK™ enabled 7700 series
modules reside in the 3RU 7700FR-C MultiFrame and communicate with the manager via the 7700FC
VistaLINK™ frame controller module, which serves as the Agent.
3. A virtual database known as the Management Information Base (MIB) lists all the variables being
monitored and which both the Manager and Agent understand. Please contact Evertz for further
information about obtaining a copy of the MIB for interfacing to a third party Manager/NMS.
For more information on connecting and configuring the VistaLINK™ network, see the 7700FC Frame
Controller chapter.
