ANALOG VIDEO OUTPUTS
1 to 8: On the 7707CVR-8 series card module, there are eight composite analog video outputs. Each
output can have cable pre-emphasis applied independently.
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 on the care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design chapter in the front of the binder.

VistaLINK®is Evertz’s remote monitoring and configuration platform which operates 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.
VistaLINK®provides centralized alarm management, which monitors, reports, and logs all incoming alarm
events and dispatches alerts to all the VLPro Clients connected to the server. Card configuration through
VistaLINK®PRO can be performed on an individual or multi-card basis using simple copy and paste
routines, which reduces the time to configure each module separately. Finally, VistaLINK®enables the
user to configure devices in the network from a central station and receive feedback that the configuration
has been carried out.
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 7707CVT-8 and 7707CVR-8 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.

6.3. VISTALINK® CONTROLLED PARAMETERS
When the MASTER jumper is set to the REMOTE position, the following parameters can be remotely
controlled through the VistaLINK®interface. When the MASTER jumper is set to the LOCAL position the
local jumper settings will override the settings configured through the VistaLINK®interface.
Parameter Description
Video 1 to 8 DC Offset A range of values describing DC Offset at the Video output (1 to 8)
Video 1 to 8 Gain A range of values describing Gain of Video 1 to 8 output as a
percentage (100 % = unity gain)
Video 1 to 8 EQ A range of values describing the pre-emphasis being applied to the
Video 1 to 8 output
Video 1 to 8 Blocking Allows user to block channels 1 to 8
New Password Allows user to change current password
Optical Power Alarm
Threshold Controls the power alarm threshold. VLPro Control Parameter Only.
