2.1.4. 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
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 section of this manual binder.

4. STATUS INDICATORS AND DISPLAYS
The 7707CVT-4 series has 6 LED Status indicators and a 4 digit alphanumeric display on the front card edge
to show operational status of the card at a glance. The card edge pushbutton and toggle switch are used to
select various displays on the alphanumeric display. Figure 5-1 shows the location of the LEDs and card edge
controls.
4.1. STATUS INDICATOR LEDS
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 video signals:
VIDEO 1 PRESENT: This Green LED indicates the presence of a valid signal on the Video 1 input.
This Red LED indicates that Video 1 input is blocked.
VIDEO 2 PRESENT: This Green LED indicates the presence of a valid signal on the Video 2 input.
This Red LED indicates that Video 2 input is blocked.
VIDEO 3 PRESENT: This Green LED indicates the presence of a valid signal on the Video 3 input.
This Red LED indicates that Video 3 input is blocked.
VIDEO 4 PRESENT: This Green LED indicates the presence of a valid signal on the Video 4 input.
This Red LED indicates that Video 4 input is blocked.

BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper J6 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.
5.2. 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
complete, 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.

6. VISTALINK®REMOTE MONITORING/CONTROL
6.1. WHAT IS VISTALINK®?
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.
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-4 and 7707CVR-4 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, 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.
