"
Do not hook up the 7707EO-HD cards that output more than -7dBm of power (see
7707EO-HD specifications for output power of various laser types) and 7707OE-HD-H
high sensitivity receiver cards directly with a short fiber optic cable. The 7707EO-HD
cards that produce more than -7dBm of power will damage the receiver if connected
directly.
SDI OUTPUT The 7707OE-HD provides three reclocked serial digital video outputs for signal
distribution. Output 3 (the bottom BNC) maintains the same polarity as the input and is DVB-
ASI compliant.
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.

4.1. STATUS INDICATOR LEDS
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid input signal or if a local 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 input
signal is present, and the board power is good.
SIGNAL VALID: This Green LED indicates the presence of a valid input signal on the optical input.
The optical input is considered valid when the module has attained lock to the
signal. If the reclocker is in non-reclock mode, then the input is considered valid
when the module detects the presence of a carrier.
CARRIER FAULT: This Yellow LED indicates a weak signal carrier on the optical input. The CARRIER
FAULT thresholds are calibrated to an optical power of -16dBm.
"NOTE: Newer cards are calibrated to –21dBm or -26dBm for the –H (high sensitivity)
version. This value is 2dBm greater than the maximum sensitivity of the cards.

4.2.3. Displaying the EDH Errors
For SD rates, EDH errors are displayed in a different manner than optical power and video standards.
When EDH error detection is enabled, the display of EDH errors will take precedence, and overwrite the
existing indication with the message EDH. The EDH error display shows if any EDH errors have occurred
during the previous 1-second interval. If the EDH errors are continuous, then the display will alternate
between the EDH display and the selected video standard or equalization displays, allowing both to be
monitored.
To enable the EDH error display, press and hold the pushbutton until the EDH DISABLE LED goes Off.
To disable the EDH error display, press and hold the pushbutton until the EDH DISABLED LED turns On.
The EDH error display can only be enabled when there is a SMPTE 259M or SMPTE 344M input signal.

5. JUMPERS AND LOCAL 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 THE RECLOCKING MODE
The RECLOCK jumper allows the user to set the reclocking mode.
RECLOCK To enable reclocking of the coaxial input signal, set the jumper to the AUTO or FORCE
positions.
Set the jumper to the AUTO position to select automatic rate selection and reclocking for
19.4,143/177/270/360/540Mb/s and 1.485Gb/s signals.
Set the jumper to the FORCED position, and the FORCE RATE jumper determines the
reclocking rate.
Set the jumper to the BYPASS position to disable reclocking of the coaxial input signal. The
timing and duty-cycle of the signal are not reconditioned in this mode.
5.2. SELECTING THE RECLOCKING RATE
The FORCED RATE jumper selects the range of reclock rates when the RECLOCK jumper is set to the
FORCE position.
FORCED RATE: Set the jumper to the SD position to select automatic reclocking of SMPTE 259M
(143-360 Mb/s), SMPTE 305M (SDTi) and SMPTE 344M (540 Mb/s) rates
Set the jumper to the HD position to select reclocking of SMPTE 292M (1.485 Gb/s) signals.
Set the jumper to the 310M position to select reclocking of SMPTE 310M (19.4 Mb/s) signals.
To perform the 310M operation the RECLOCK jumper must be set to FORCE, and the FORCED RATE
jumper must be set to 310M.
5.3. 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.

7707OE-HD SD/HD Re-Clocking Fiber to Electrical Converter
Revision 1.2.2 7707OE-HD-9
5.4. SELECTING WHETHER MODULE WILL BE CONTROLLED FROM THE
LOCAL CONTROLS OR THROUGH THE VISTALINK®INTERFACE
The MASTER jumper selects whether the module will be controlled from the local user controls or through
the VistaLINK®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 VistaLINK®interface. The adjacent yellow LED will be On when VistaLINK®control in
enabled. This LED is intended to alert the user that local controls are not currently active.
5.5. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE: The 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 NOTE 1 below). See the
Upgrading Firmware section 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 UPGRADE position (see NOTE 1). 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.
NOTE 1: The Rev (A) boards have incorrect labeling for the RUN / UPGRADE modes. The jumper
labels shown in Figure 4-1 are correct. On Rev (A) boards, for normal RUN operation set the
jumper to the UPGRADE position (as shown on the board label - away from the front of the
module). For UPGRADE operation the jumper must be set to the RUN position (as shown on
the board label - closest to the front of the board).

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-HD 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.
