7780DLY-ASI ASI Delay
1. OVERVIEW
The 7780DLY-ASI is a full function ASI Delay module designed for applications such as: satellite uplink, redundant path matching, and matching delays in the compressed domain caused by multi-path compression and distribution.
The 7780DLY-ASI will delay any transport streams with any content (MPEG-2, H.264, VC-1, data, audio, etc…). It is completely agnostic of the content of the stream.
The 7780DLY-ASI offers up to 16 seconds of delay in 1 ms increments.
Model Video Standard Delay Range Bitrate
7780DLY-ASI DVB ASI
65 µs up to 16 seconds
From 100Kbits/s to 213Mbits/s
The 7780DLY-ASI ASI Delay modules will delay the complete ASI stream bit by bit maintaining any transport stream timing and ASI packet distribution. The delay can be set in seconds with 1 ms increments.
With the broadcast environment in mind, the modules feature bypass relay protection to one output. The 7780DLY-ASI ASI Delay modules are housed in a 3RU frame that will hold up to seven 7780DLY-ASI modules or a 1RU frame that will hold up to three modules.
Features:
• 1 ASI input 100kb/s to 213Mb/s and 2 ASI outputs
• Delay from few bytes to 16 seconds in 1ms increment
• Support 188 and 204 bytes packets (Auto-detect)
• ASI input test includes:
- Sync Byte error and Sync loss detection
- Total Bitrate
- Useful Bitrate
- Null packet Bitrate
- Continuity count error
- List of active PIDs
• Controlled by VistaLINK
• Fully integrated with the industry leading Evertz VistaLINK

4. STATUS LEDS
The 7780DLY-ASI has 2 LED Status indicators on the main circuit board and 1 indicator on the sub­module to show operational status of the card at a glance. Figure 7-1 and Figure 7-2 shows the location of the LEDs and card edge controls.
Two large LEDS on the front of the main 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 input signal 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 the board power
is good and the module detects a valid input.
SIGNAL PRESENT: This Green LED will be ON when there is a valid ASI signal present at the module
input.
One LED on the sub-module (7700CC) indicates the presence of the ASI TS input.

5. CARD EDGE CONTROLS - 7780DLY-ASI

The 7780DLY-ASI module is equipped with a 4 position DIP switch on the top edge of the card to allow the user to select various functions. All positions are assigned sequentially such that the DIP switch 1 is located farthest from the front of the card. Table 5-1 gives an overview of the DIP switch functions for the 7780DLY-ASI. Sections 5.1 and 5.2 describe the assigned DIP switch functions. The On (closed) position is down, or closest to the printed circuit board. The Off (open) position is up, or farthest from the printed circuit board. There is also a toggle switch and pushbutton which are used to navigate the on screen menu. (See section 6).

6. USING THE ON SCREEN MENU

An On Screen Display (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.
The OSD menu system is always present on the SDI output. 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 selecting. 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 to the main status display.
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 options, 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.

NOTE: THERE IS NO PICTURE DISPLAYED ON THE SDI OSD AS THE INPUT OF THE 7780DLY-ASI IS A COMPRESSED STREAM AND THE CARD DOES NOT HAVE AN MPEG-2 DECODER.

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 Power
Supplies 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.

7.2. CONFIGURING THE MODULE FOR FIRMWARE UPGRADES UPGRADE: The UPGRADE jumper J15 located near the front of the sub-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, pull it out of the frame. Move Jumper J15 to
the UPGRADE position. Install the Upgrade cable provided (located in the vinyl pouch in the front of this manual) onto header J14 at the card edge. Re-install the module into the frame. Perform the upgrade as described in the Upgrading Firmware chapter. Once the upgrade is complete, remove the module from the frame, move J15 to the RUN position, remove the upgrade cable and re-install the module. The module is now ready for normal operation.

8. VISTALINK® REMOTE MONITORING/CONTROL

8.1. WHAT IS VISTALINK®?

7700 MultiFrame Manual
7780DLY-ASI ASI Delay
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 routines, which reduces the time to configure each module separately. Finally, VistaLINK
PRO can be performed on an individual or multi-card basis using simple copy and paste
®
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 VistaLINK
®
-C Configuration Utility graphical user interface (GUI), third party or custom manager software may be used to monitor and control Evertz VistaLINK
enabled products.
®
2. Managed devices each with a unique address (OID), communicate with the NMS through an SNMP Agent. The 7780DLY-ASI communicates directly with the manager using its internal 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.
