2. INSTALLATION
The 7707AT-A series modules come with a companion rear plate that has analog audio connections and
an SC/PC (shown), ST/PC or FC/PC optical connector. Each version provides analog audio connections
via multi-pin removable terminal blocks. For information on mounting the rear plate and inserting the
module into the frame see the 7700FR chapter section 3. The following diagram shows rear plate options
for each 7707AT-A version:
Figure 2-1: 7707AT-A Rear Panels
2.1. OPTICAL CONNECTIONS
FIBER OUTPUT: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical
output of the 7707AT-A. This optical output is available in 1310nm, 1550nm, and up
to sixteen CWDM wavelengths (ITU-T G.694.2 compliant) and is compatible with
multimode fiber when connected directly to a companion 7707AR-A card.

Page - 4 Revision 2.3
2.2. AUDIO CONNECTIONS
AUDIO INPUTS: The 7707AT-A series modules provide terminal block input connections compatible
with either balanced or unbalanced analog audio. Balanced audio signals should be
connected to the positive (+) and negative (-) input terminals. Unbalanced audio
signals should be connected to the positive (+) input terminal, while the negative (-)
input terminal is connected to ground. The audio cables can be secured into the
removable portion of the terminal strips using a small screwdriver. The removable
part of the terminal strip is then inserted into the rear panel.

The shield should be connected at one end of the cable, only to minimize cable
ground loops.
Shield ground loop currents may arise, if the source equipment “shield ground”
potential is significantly different from 7707AT-A local power ground and the
shield is grounded at both ends. The card can tolerate about 0.5A of any resulting
ground loop current. Exceeding this limit risks causing catastrophic failure of the
card.

2.3.4. 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 maintains 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 regarding care and handling of
fiber optic cable see section 3 of the Fiber Optics System Design section of this manual binder.

5. JUMPERS
Several jumpers, located at the front of the module are used to preset various operating modes. Figure
4-1 shows the locations of the jumpers.
5.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper 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
RUN/UPGRADE: The RUN/UPGRADE jumper 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 in the front of the binder for more information.
To upgrade the firmware in the module unit pull it out of the frame. Move the
RUN/UPGRADE jumper J16 into the UPGRADE position. Install the Upgrade cable
provided (located in the vinyl pouch in the front of the binder) onto SERIAL header
J27 at the card edge. Re-install the module into the frame. Run the upgrade as
described in Upgrading Firmware chapter in the front of the binder. Once the
upgrade is completed, remove the module from the frame, move J16 into the RUN
position, remove the upgrade cable and re-install the module. The module is now
ready for normal operation.

6. 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.
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 VL-Fiber demo 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 7707EO and 7707OE 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.
