!As of July 2004 the 7742DLY-HD has been discontinued, but the documentation is
included here for customers with existing units.
The 7740DLY-HD modules will delay all VBI and Ancillary data including embedded audio along with the
video. The delay can be set in frames, lines and samples or in seconds.
With the broadcast environment in mind, the modules feature bypass relay protection one output.
The 7740DLY-HD modules are housed in a 3RU frame that will hold up to 7-7740DLY-HD series modules
or a 1RU frame that will hold up to 3 modules.
Features:
•Full signal delay capability including VBI and ANC DATA for SMPTE 292M (1.5Gb/s) signals
•7743DLY-HD also supports full signal delay capability including VBI for SMPTE 259M (270Mb/s)
signals
•Delay programmable in video units (frames, lines, and samples) or as time units (seconds)
•Auto senses video standard
•Bypass relay for program path protection on power loss
•Card edge controls operate on screen menu system to program delay settings
•VistaLINK™ - enabled offering remote control and configuration capabilities via SNMP using
VistaLINK™ Pro or 9000NCP Network Control Panel. VistaLINK™ is available when modules are

7740DLY-HD series HD Video Delay
7740DLY-HD-4 Revision 1.3.1
2.2. GENLOCK REFERENCE
GENLOCK This BNC is used to connect a video or tri-level sync reference. The genlock signal may be
NTSC or PAL colour black, or tri-level sync and is autodetected by the module. The
genlock standard must be set using the DIP switches 1 to 3. (See section 5.1) Jumper J9
on the 7700CC submodule selects whether the reference input is terminated to 75 ohms or
high impedance (default). (See section 8.3). The output video can be timed with respect to
the genlock video using the Reference Phase menu items. (See section 7.2.1) When no
Genlock is provided, the output video is timed with respect to the input video. In order to
meet the jitter tolerance specifications outlined in section 3.2 a genlock reference must be
applied.
2.3. GENERAL PURPOSE INPUTS
A 25 pin D connector labeled GPI contains 8 GPI inputs. The connector pinout is shown in Table 1.

7. USING THE ON SCREEN MENU
An On screen menu (OSD) is used to configure many of the module’s parameters. The three position,
return to center, toggle switch and momentary pushbutton located on the front edge of the module are
used to navigate the OSD setup menus and configure the cards various controls.
To enter the OSD menu system, press and hold the pushbutton and then press the toggle switch up for 3
seconds. This will bring you to the main setup menu where you can use the toggle switch to move up and
down the list of available sub menus. An arrow (>) moves up and down the left hand side of the menu
items to indicate which item you are currently choosing. Once the arrow is on the desired item, press the
pushbutton to select the next menu.
On all menus, there is a selectable item Done. Selecting Done will take you to the previous menu (the one
that was used to get into the menu). If you are at the top level of the menu tree then selecting Done will
exit the OSD menu and return the module to the normal operating mode.
Once you are in a sub menu, there may be another menu level, or there may be a list of parameters to
adjust. If there is another set of menu choices, use the toggle switch to select the next choice with the
same procedure as in the main menu.
If there is a list of parameters to adjust, use the toggle switch to move up or down to the desired parameter
and press the pushbutton. The arrow will move to the right hand side (<) indicating that you can now
adjust the parameter. Using the toggle switch, adjust the parameter to its desired value. If the parameter
is a numerical value, the number will increase if you lift the toggle switch and decrease if you push down
on the toggle switch. If the parameter contains a list of choices, you can cycle through the list by pressing
the toggle switch in either direction.
When you have stopped at the desired value, depress the pushbutton. This will update the parameter with
the selected value and move the arrow back to the left side of the parameter list. Continue selecting and
adjusting other parameters or use the Done commands to return to the next higher menu level.

7.2. CONFIGURING THE VIDEO OUTPUT PHASE
The Reference Phase menus are used to the output video timing. The chart below shows the items
available in the Reference Phase menu. Sections 7.2.1.1to 7.2.1.2 give detailed information about each of
the menu items.
VSets the vertical phase of the output signal to the genlock reference input
HSets the horizontal phase of the output signal to the genlock reference input
7.2.1. Setting up the Video Output Timing
The output stage of the 7740DLY-HD contains a frame buffer and a line buffer so that the output video can
be timed with respect to the reference applied to the GENLOCK input BNC. In the absence of a genlock
signal the output video will be timed with respect to the incoming Video.
!
The V and H phase adjustments are REAL TIME ADJUSTMENTS and will affect the
output video timing immediately. These settings should not be adjusted when the
output video is in the broadcast chain.

7.2.1.1. Setting the Vertical Phase of the Output Video
Reference Phase
V
1 to Max Lines
1
With this control, you can set the vertical timing of the output video with
respect to the genlock reference input. There are separate settings of V
phase offset for each output video type. Setting this control to 1 keeps the
output video in time with the Genlock reference or incoming video if genlock
is missing.
Increasing the value will delay the output video in one-line increments of the
output video standard. In order to advance the vertical timing of the output
video with respect to the genlock video, set the control to the maximum total
number of lines of the output video minus the number of lines that you wish
to advance the output video. (E.g. for 1080i/59.94 output video the total
number of lines is 1125, so to advance the output video 5 lines set the value
to 1120.) When increasing the V Phase Offset value causes it to go beyond
the limit of the frame buffer, the V Phase Offset will wrap to the beginning of
the frame buffer, resulting in a change of one frame of throughput delay
between the video input and the video output.
7.2.1.2. Setting the Horizontal Phase of the Output Video
Reference Phase
H
0 to Max samples
0
With this control, you can set the horizontal timing of the output video with
respect to the genlock reference input. There are separate settings of V
phase offset for each output video type. Setting this control to 0 keeps the
output video in time with the Genlock reference.
Increasing the value will delay the output video in one-sample increments.
In order to advance the horizontal timing of the output video with respect to
the genlock video, set the control to the maximum number of samples per
line for the output video standard minus the number of samples that you
wish to advance the output video. (E.g. for 1080i/59.94 output video the
total number of samples per line is 2200, so to advance the output video 5
samples set the value to 2195.)

8.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
FRAME STATUS The FRAME STATUS jumper J22 located at the front of the main module
determines whether local faults (as shown by the Local Fault indicator) will be
connected to the 7700FR frame's global status bus.
To monitor faults on this module with the frame status indicators (on the PS 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.
8.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES
UPGRADE The UPGRADE jumper J16 located at the front of the main module 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 Jumper
J16 into the UPGRADE position. Install the Upgrade cable provided (located in the
vinyl pouch in the front of this manual) onto header J24 at the card edge. Re-install
the module into the frame. Run the upgrade as described in Upgrading Firmware
chapter. 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.

8.3. SELECTING WHETHER THE GENLOCK REFERENCE INPUT IS TERMINATED
TERM The TERM jumper J9 located at the rear of the APB3FMTCON submodule is used to
terminate the genlock loop input. Then it is in the 75R position a 75 ohm terminating
resistor will connect the input to ground. When it is in the HI-Z position the genlock loop
input will be high impedance.
9. VISTALINK™ REMOTE MONITORING/CONTROL
9.1. WHAT IS VISTALINK™?
VistaLINK™ is Evertz’s remote monitoring and control capability 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. For monitoring there needs
to be a detecting device that automatically reports all errors to a central alarm and error logging station.
We also need to be able to interrogate individual detector devices from the central station to determine the
status of individual channels. Finally, we need to be able to configure devices in the network from the
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 7707MB), 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.
