Crystal Vision Introduction
1 Introduction
The VDA110M HD is a 1-in, 11-out distribution amplifier with continuously variable
gain and equalisation for up to 300 metres of coaxial cable for use with both Standard and
High Definition composite signals.
The VDA110M HD may be used with the RM01 and RM09 single slot rear connector, the
RM02 and RM10 quadruple slot rear connector and the RM16 and RM18 double slot rear
connectors. A single slot rear connector provides five equalised outputs. Five or six extra
outputs and an input loop-through are available with alternative frame rear modules.
Input termination is link selectable and passive loop-through is independent of the
amplifier. The module may be removed without losing the looped-through source.
VDA110M HD is a very compact board, with 24 modules fitting in a 4U frame when a
single slot rear connector is used.
VDA110M HD analogue video DA
The VDA110M HD has LED and GPI indication of input presence/failure.
The main features are as follows:
•1 in 11 out video distribution amplifier (use RM18 for 11 outputs)
•Continuously variable equalisation for up to 300 metres of coaxial cable.
•GPI/LED input presence indication
•SD/HD composite capable
•Card edge control
The unit plugs into the front of the rack frame, and the universal connection system
allows a mixture of Crystal Vision modules in the frame. The hinged front panel of the
case reveals LED indication of input status and controls for cable equalisation and gain.

Crystal Vision Hardware installation
2 Hardware installation
The VDA110M HD single channel 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.
2.1 Universal rear connectors
When used with a single height rear connector, the 4U Indigo frame will house up to 24
modules and three power supplies, 2U Indigo frame will house up to 12 modules and two
power supplies, the 1U Indigo frame will house 6 modules and a single or dual power
supply. The 1U desktop box has a built-in power supply and will house up to 2 modules
with a single height rear connector.
The 4U, 2U and 1U frames have a hinged front panel, which gives access to the PSU and
all modules. The desktop 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.
There are six types of rear connector available that provide system flexibility by allowing
a mix between total I/O access and module packing density.
The VDA110M HD may be used with the RM01 and RM09 single slot rear connector for
up to 24 modules, the RM02 and RM10 quadruple slot rear connectors for up to 8
modules and the RM16 and RM18 double slot rear connectors for up to 12 modules in a
4U frame.
Note:
The 1U Indigo frame and desk top box will not accept either the quad height RM02 or
RM10.
The following table summarises the rear connectors available and their recommended use.

2.3 General purpose interface
Each frame slot has up to six connections ‘a’ to ‘f’ for GPI control and monitoring. These
connections are available at the rear of the frame on the 26-way D-type remote
connectors.
GPI Low (<1V) High (+5V)
1 ‘a’ Input status Input present Input absent
2-6 ‘b-f’ Not used
As supplied, each GPI output has a 220Ω resistor in series with its output. This allows for
an external LED to be driven, connected to a DC voltage of +5V.
GPI input connections have 10kΩpull-up resistors to the internal chassis +5V.
4U frame GPI connections
GPI lines ‘a’ to ‘f’ of each card connect to one of eight rear remote connectors as follows:
