DA-VA Rev. H
1 Product overview
The Flashlink DA-VA is an analog video distribution amplifier module with passive input
loop providing high performance media distribution for analog signals from DC to 200
MHz. The module also complies with the SMPTE 259 M specification for SDI signals.
The input signal is distributed to 6 equivalent outputs. The input is switch able to high
impedance for multi drop purposes. Outputs have 75 ohms impedance. A signal
detector will indicate if signal is present (LED and GPI).
The DA-VA is designed for all distribution purposes in studio, duplication and broadcast
applications.
The DA-VA is well suited for distribution of AES-3id signals (75 ohms unbalanced AES
over coaxial cables).
DA-VA comes with a passive input loop with the default -C2 backplane (Default since
November 2011).

3 Connections
The DA-VA has a dedicated connector module: DA-VA-C2. This module is mounted at
the rear of the sub-rack. The module is shown in figure 2. This backplane replaced the
DA-VA-C1 backplane with the feature upgrade of incorporating the passive loop on the
backplane. Figure 3 shows the discontinued DA-VA-C1 backplane.

The electrical input signal is connected to the IN BNC and the electrical outputs are
connected to the O1 to O6 BNC’s. Please note that all 6 outputs are non-inverted. On
the back side of this board, there is a DIP switch to set the termination. If switch 1 is on,
there is a 75 ohms termination. DIP switch 2 is not used.
3.1 Mounting the connector module
The details of how the connector module is mounted, is found in the user manual for
the sub-rack frame FR-2RU-10-2.

4 Operation
The status of the module can be monitored in three ways.
1. GYDA System Controller (optional)
2. GPI at the rear of the sub-rack
3. LED’s at the front of the sub-rack.
Of these three, the GPI and the LED’s are mounted on the module itself, whereas the
GYDA System Controller is a separate module giving detailed information on the card
status. The functions of the GPI and the LED are described in sections 5.1 and 5.2.
The GYDA controller is described in a separate user manual.
4.1 GPI ALARM – Module Status Outputs
Only available when using the standard –C1 backplane
These outputs can be used for wiring up alarms for third party control systems. The
GPI outputs are open collector output, sinking to ground when an alarm is triggered.
The GPI connector is shown in figure 4.
Electrical Maximums for GPI outputs
Max current: 100mA
Max voltage: 30V

4.2 Front Panel - Status Monitoring and Signal Detection
The status of the module can be monitored visually at the front of the front of the
module.
The DA-VA has one LED showing the status. The hardware revision 2 of the DA-VA
has also a built in detector for signal monitoring. When signal is present, LED is green,
otherwise it will be red. The LEDs are described in the following table:
