1Introduction
ENDAC is a 12-bit broadcast encoder with four outputs that can be configured to give a
variety of component and composite signals.
ENDAC will fully integrate with any other interface or keying product from the Crystal
Vision range. Further flexibility is afforded by the large choice of control options. Control
options include board edge control, local or remote active control panel and the Statesman
PC Control System.
•12-bit digital encoder
•Flexible control, including PC software.
•Three link configurable outputs, 1 fixed composite output
•Compact design for high packing density
ENDAC 12-bit Encoder
ENDAC is a 100mm x 266mm module that fits in Crystal Vision four standard frame
sizes. 24 modules fit in 4U, 12 modules fit in 2U, six in 1U or two in a desktop box. There
are a range of rear connector modules available for the ENDAC which allow the system
builder great flexibility in frame configuration.

1.1 Operating modes
Analogue video formats
There are four analogue video outputs of which one is a fixed composite output. The other
three video outputs can be configured using on-board links to produce a selection of
further composite outputs, YC, GBR or YUV component (Y’P’b P’r or Y’C’b C’r). 625
and 525-line output standard can be set. Data in the VBI (vertical blanking interval) is
passed to the analogue composite output. The addition of a 7.5% IRE setup is also
selectable when outputting an NTSC format signal. Betacam signal levels can also be
selected for component YUV outputs.
Status and control
Status and control is available using the board edge menu selection switches and LEDs.
Control and status reporting is also available from either an active frame front or remote
active control panel. PC control is also available using Crystal Visions Statesman PC
controller package.
Note. When the ENDAC is set to remote control mode the position of the board edge
switches may not reflect the actual configuration of the card. Returning the card to local
control will reinsert the board edge configuration

2Hardware installation
The ENDAC single height module uses the RM01, which will fit into all Crystal Vision
rack frames. All modules can be plugged in and removed while the frame is powered
without damage.
The ENDAC can also be used with several other rear modules such as the RM02 and
RM18 but at reduced packing density.
2.1 Rear modules and signal I/O
The Indigo 4 4U frame will house up to 24 single height modules with up to three power
supplies. The FR2AV and Indigo 2 2U frames will house up to 12 single height modules
and dual power supplies. The FR1AV and Indigo 1 1U frames will house six single height
modules and a single power supply. The DTBAV and Indigo desk top boxes both have a
built-in power supply and will house up to two single height modules.
Note: For details of fitting rear connectors please refer to the appropriate frame manual
Rear module connections with RM01
The RM01being a single height module will allow maximum packing density with the
maximum number of outputs available.

5Statesman
The Crystal Vision Statesman PC control software is designed to control a range of
Crystal Vision modules via serial control from a PC.
The main Statesman application communicates with each module in a frame that is fitted
with an active front panel. This panel can be with or without a LCD display. Statesman
will not be able to detect modules used in a frame with only a passive front panel unless it
is part of an active/passive combination.
5.1 Installing Statesman
Minimum pre-requisites:
•A PC running Windows 98, NT4 with SP 5 or higher Windows 2000 or Windows XP
•A parallel port dongle supplied with the Statesman software package
•An RS422 serial connection from the host PC to the Indigo frame control input or to Remote 2
connector on an FR1AV or FR2AV Crystal Vision frame with at least one FTX202 module
and/or other Statesman compatible module
•An active control panel MUST be fitted to the frame with version 1.63 or above firmware – if it is
an Indigo frame the firmware must be V1.04 or above
•An optional RS422 to RS232 converter if the PC has no RS422 ports
Installing Statesman
•Refer to the readme and/or help file on the CD before proceeding
•To view all application windows, set graphics resolution to at least 1024 x 768
•Remove any previous version of the Statesman software using the Add/Remove Programs
application in the Windows Control Panel
•Ensure that the Statesman dongle is fitted to the parallel port of the host PC
•Insert the Statesman CD and the installation should start immediately – if it does not, run the
setup.exe file on the CD
•Obey any installation program prompts and restart the PC when prompted
Running Statesman for the first time
The Statesman PC Control System may be run from the Crystal Vision programs folder
via the Start menu or by double clicking on the Crystal Vision.exe file in the installed
program directory.
When the program runs it will require licence information and an administrator name and
