DAC-AVA-DMUX+

SD/HD video DAC. Optional 2xSDI out, internal audio handling, and
frame synchronizer functionality.

DAC-AVA-DMUX-R+

SD/HD video DAC with high sensitivity 9/125µm single mode optical
input. Optional 2xSDI out, internal audio handling, and frame
synchronizer functionality.

1 Product overview

The Flashlink DAC-AVA-DMUX is an HD-SDI/SD-SDI video DAC with built-in frame
synchronizer, optional SDI outputs and optional audio and data outputs.

At the heart of the DAC-AVA-DMUX is an HD/SD frame synchronizer with an adjustable
delay relative to the sync signal. The module accepts black & burst or a tri-level signal from
the frame. The DAC-AVA-DMUX also has a de-glitcher to give error-free synchronous
switching.

A set of configurable analog video outputs and two optional SDI digital outputs are
provided.

The audio embedded in the HD-SDI or SD-SDI stream is de-embedded and can be delayed
relative to video. Each audio channel can be swapped in an audio matrix before they are re­embedded in the SD-SDI data output stream. It is also possible to turn embedding
completely off and leave the SDI stream unaltered.

A selection of user parameters of the card can be controlled by switches on the board.
Complete control of all parameters is available by use of the Flashlink RS422 Control
Protocol Version 4, which is supported by the Multicon system controller.

1.1 Hardware products

Two hardware versions of the DAC-AVA-DMUX exist:

1.2 Software options

The base products DAC-AVA-DMUX / DAC-AVA-DMUX-R do not have the frame­synchronized SDI outputs enabled, or the AES and analog audio outputs enabled. Nor do
they have the ability to receive SD-SDI or HD-SDI input signals. This means that at least
one these two input capabilities must be ordered as a factory option or purchased as a
software key upgrade at a later time in order to have a useful product.

The following table summarizes the ordering options available (for prices, please contact

Table 1: Available options

At the bottom of the information page (the ‘front page’) of the module in Multicon GYDA a

line will show which features are enabled:

This example shows a module with all optional features present.

1.2.1 How to apply a software key that enables new options

1) In Multicon Gyda, navigate to the DAC-AVA-DMUX module in question by first
pressing the frame symbol and then pressing the icon for the DAC-AVA-DMUX. In
the example picture below, two such modules are present in the same frame, and
the one in slot 1 has been selected.

Figure 2: A frame with two DAC-AVA-DMUX modules

2) Check which features are already enabled in the module. At the bottom of the

information page that is now shown will be a line that says “Purchased features”,

which lists the enabled input formats, whether the SDI outputs are enabled, and
finally whether the AES/analog audio outputs are enabled or not. In the examples
shown here, all optional features are already enabled and no further upgrades are
available.

Figure 3: How to see purchased features, new Multicon Gyda

Older versions of Multicon Gyda cannot display the line “Purchased features”
properly, the words “SD:”, “HD:”, “SDI:” and “Audio:” will be missing.

Figure 4: How to see purchased features, older Multicon Gyda

If for instance “HD:” should say “No”, this feature can be purchased as a software
key upgrade.

3) If the customer decides to buy a feature upgrade, Nevion will need both the serial

number of the module to be upgraded and a list of the new features the customer
wishes to purchase for it.
The serial number can be found on the very bottom of the configuration page for the
module (To navigate between the information page and the configuration page,
press the “i” symbol and the wrench symbol, respectively).
Each new input format or feature has its own order number in the price list.

Figure 5: Where to find the serial number

4) The customer will receive a software key from Nevion. The key will be in the form of

the string “optn 0” plus six groups of up to 10 digits. Like this, but with different
numbers:

optn 0 1234567890 1234567890 1234567890 1234567890 1234567890
1234567890

This software key is linked to the serial number of the module and must be sent to
the module via the debug terminal in Multicon Gyda.
To access the debug terminal, hover the mouse over the cog wheels and select
“Debug terminal” from the drop-down menu. See figure Figure 6 below.

Figure 6: How to get to the Debug terminal in the current Multicon version

In previous versions of Multicon, the user must first select “Config” in the top menu,
and then press “Debug terminal”, see Figure 7 and Figure 8 below.

Figure 7: Step one to access the Debug terminal in the previous Multicon version

Figure 8: Step two to access the Debug terminal in the previous Multicon version

5) Now comes the only tricky part of the procedure: To address a particular module

through the debug terminal, one has to take the frame number and slot number and
make a unique two-digit address from them. To do this, multiply the frame number
from the Multicon GUI with 10, then add the slot number from the Multicon GUI, and
finally subtract 1.
Another way of saying this is that the left digit of the address is the frame number,
and the right digit is the slot number minus one, i.e. slots counted from 0 to 9,
instead of 1 to 10 as they are displayed in the Multicon user interface.
The two modules in our example were both in frame 0, but in slots 1 and 5
respectively. This gives us the addresses “00” (0*10 + 1 - 1) and “04” (0*10 + 5 - 1).

Before trying to send the software key it could be wise to check that the addressing

is indeed correct. That can be done by sending a single question mark (“?”) to the

module. In the Flashlink protocol this is known as the “hello” command, and is
basically a who-are-you command. The module should identify itself with the module
type, version information, and serial number. In the example below the hello
command has been sent to the module in frame 0/slot 5 (that is, address “04”), and
the module has replied. Then the software key “optn 0 123456 123 …” has been
copy-pasted into the command field and is ready to be sent to the module. The
command will be sent when the “Ok” button is pressed. The module will then reply
with “ok”, and restart with the new features enabled. It will take a few seconds
before Multicon Gyda rediscovers the module after the restart.

6) Remember to check that the module now has the new features enabled. Please

refer to step 2).
