2. Installation
The 7707AR series modules come with a companion rear plate that has AES audio connections and an
SC/PC (shown), ST/PC or FC/PC optical connector. The 7707AR-8 and 7707AR-16 versions provide AES
connections via multi-pin removable terminal blocks. The 7707AR-8U version provides AES connections
via BNCs. The 7707AR-8U-DB version provides unbalanced AES connections via a DB-25 connector,
which is backwards compatible with the 7705AR-8
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 7707AR version:
Figure 2-1: 7707AR Rear Panels

7700 MultiFrame Manual
7707AR Multi-Channel AES Fiber Receiver
7707AR-4 Revision 1.2
2.1. OPTICAL CONNECTIONS
FIBER INPUT: There is one SC/PC (shown), ST/PC or FC/PC female connector with the optical input
to the 7707AR. This wide band optical input accepts optical wavelengths of 1270nm
to 1610nm, accommodating standard, CWDM or DWDM transmission schemes. This
input is compatible with multimode fiber when connected directly to a companion
7707AT card.

Do not hook up the 7707AT DWDM cards and 7707AR cards directly with a short
fiber optic cable. The 7707AT DWDM card produces +7dBm of power which will
damage the receiver if connected directly.
2.2. AES CONNECTIONS
AES OUTPUTS: The 7707AR-8U version provides BNC output connections compatible with
unbalanced AES audio. The 7707AR-8U-DB version has DB-25 connections for
unbalanced audio that are backwards compatible with 7705AR-8 as shown in Figure
2-2. The 7707AR-8 and 7707AR-16 versions provide terminal block output
connections compatible with either balanced or unbalanced AES. Balanced AES
audio signals should be connected from the positive (+) and negative (-) output
terminals. Unbalanced AES audio signals should be connected from the positive (+)
output terminal, while the negative (-) output terminal remains disconnected. Output
impedance, amplitude, and rise/fall times are selectable to accommodate balanced or
unbalanced interfaces. Refer to section 4.2.3 for information on selecting balanced or
unbalanced output configurations.
 For 7707AR-8U-DB versions the outputs should be set to the unbalanced
configuration.

2.3. 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 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 chapter in the front of the binder.

4.1. STATUS INDICATOR LEDS
LOCAL FAULT: This red LED indicates poor module health. Two conditions could cause this fault
indication to be active: A link with a companion 7707AT has not been achieved, or if
a card power fault exists (i.e. a blown fuse). The LOCAL FAULT indication can also
be reported to the frame by setting the FRAME STATUS jumper.
MODULE OK: This green LED indicates good module health. It will be on while a link is maintained
with a companion 7707AT, and the card power is good.
CH:01 to CH:xx Each of these green LED’s indicate the signal presence of the respective AES
output channel. Signal presence indication considers X and Y preambles in
processed AES.
4.2. CARD-EDGE DISPLAY AND CONTROLS
Additional signal and status monitoring is provided via the 4-digit dot-matrix display located at the card-
edge. The card-edge pushbutton and toggle-switch are used to navigate through the display menu. Figure

5. JUMPER CONTROLS
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.

5.3. 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. 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.
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.
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
®
