Crystal Vision Introduction
19/09/05 2DDA108A User Manual V4.10
1 Introduction
The DDA108A is a non-reclocking serial digital video and ASI distribution amplifier with
up to eight outputs. It has auto-equalisation for up to 250 metres of coaxial cable.
The universal connection system allows a mixture of Crystal Vision modules in the frame.
The modules plug in the front and the rear connectors plug in the rear. Depending on
frame design, a hinged or removable front panel reveals LED indication of input and PSU
status when opened.
DDA108A non reclocking ASI/SDI distribution amplifier
The DDA108A may be used with the RM01 single slot rear connector, the RM02
quadruple slot rear connector and the RM18 double slot rear connector. A single slot rear
connector provides five equalised outputs and three extra outputs are available with the
double and quadruple slot connectors.
It is very compact with 12 modules fitting in a 2U frame when a single slot rear connector
is used.
Further rear connector details may be found in the Installation chapter.
The main features are as follows:
•1 in 8 out DVB-ASI/SDI distribution amplifier
•Automatic equalisation for up to 250 metres of coaxial cable
•LED input presence indication
•Card edge control
Note: This manual covers the DDA108A. The DDA108 with 8 re-clocked SDI outputs is also
available.

3 Hardware installation
The DDA108A digital video distribution amplifier fits into all Crystal Vision rack frames.
All modules can be plugged in and removed while the frame is powered without damage.
3.1 Universal rear connectors
When used with a single height rear connector, the 2U Indigo or FR2AV frame will house
up to 12 modules and dual power supplies, the 1U Indigo or FR1AV frame will house 6
modules and a single power supply. The 1U Desk Top Box has a built-in power supply
and will house up to 2 modules with a single height rear connector.
The 2U and 1U frames have a hinged front panel which gives access to the PSU and all
modules. The Desk Top Box has a removable front. The universal frame wiring system
allows any of the interface range of modules to be fitted in any position with the use of
removable rear modules.
The DDA108A may be used with the RM01 single slot rear connector, the RM02
quadruple slot rear connector and the RM18 double slot rear connector.

3.2 General purpose interface
The external GPI control lines 'a' to 'f' at the frame remote connectors are provided to
allow remote control and/or remote status indication. Line 'a' is assigned as a GPI output
to provide remote indication of input presence.
The GPI output is fitted with 6k8Ω pull-up to +5V and 270Ωseries resistor so it can drive
an LED directly. If the series resistor is shorted out, it can drive a bulb at +45V 500mA
max.

4 Problem solving
Basic fault finding guide
The Power OK LEDs are not illuminated
Check that the frame PSU is functioning – refer to the appropriate frame manual for detailed
information
Check that the card is seated correctly in the frame
There is no video output
Check that a valid video input is present and that any cabling is intact
The video output is low quality
Check that the maximum length has not been exceeded
The card no longer responds to card edge control
Check that the card is seated correctly and that the +5V LED is lit
If necessary re-set the card
Re-setting the card
If required, the card may be reset by simply removing the rack power and re-applying power after a
few seconds or by removing the card from the rack and then re-inserting the card
It is safe to re-insert the card whilst the rack is powered
