Crystal Vision Introduction

1 Introduction

The VDA210R is a dual analogue video distribution amplifier with two inputs. In dual

channel mode it supports up to five main outputs per channel. In single channel mode, it

supports up to ten main outputs.

It has adjustable gain, equalisation and clamp and gives sophisticated error reporting,

including dark and white clip video. Input termination is link selectable.

The VDA210R may be used with the RM01 single slot rear connector, the RM02

quadruple slot rear connector and the RM15 and RM18 double slot rear connectors.

The rear module used determines the number of loop-though and main outputs. Passive

loop-through is independent of the amplifier; the module may be removed without losing

the looped-through source.

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 Dark, Clip, Input Sync Error

line standard (525/625), PSU status and controls for cable equalisation, gain and output

clamping.

General-Purpose Interface lines are also provided to indicate dark, clip and input

presence.

The main features are as follows:

•Dual 1 in 5-out or single 1 in 10-out video distribution amplifier

•Continuously variable equalisation for up to 300 metres of coaxial cable.

•GPI dark, clip and input presence indication for each channel

•Inputs may be terminated in 75Ωor left unterminated (HiZ) – on-board jumper

•Optimise error correction and clamp for channel two signal type – ideal for split

Luma/Chroma operation

•Bulb or LED GPI drive capability

•Card edge, active/remote panel and Statesman control options

Note: This manual covers the dual channel VDA210R. The single channel VDA110R and the

VDA110M/210M without remote control are also available.

Crystal Vision Installing Statesman

22/09/05 5VDA210R User Manual V3.21

2 Installing Statesman

The Crystal Vision Statesman PC control software is designed to control a range of

Crystal Vision modules via serial control from a PC. Statesman provides a user friendly

means of configuring and operating the VDA210R with the benefit of see-at-a-glance

status monitoring. Most functions can be accessed from Statesman menus.

The main Statesman application communicates with each module in a frame through an

active or Statesman enabled control panel. A passive panel cannot be used for Statesman

control.

Minimum pre-requisites:

•A PC running either Windows 2000 or Windows XP is recommended

•A parallel port dongle for Statesman PCs with attached Crystal Vision frames

•An RS422 serial connection from the host PC to the Control/422 RJ45 or

Remote/RMT 2 connector on Crystal Vision frames

•An active or Statesman enabled 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

password. It will also need to know which computer port is being used to connect to a

Crystal Vision frame(s).

Note: For further details of Statesman configuration please refer to the Statesman manual.

3 Statesman operation

Once Statesman is configured it should automatically detect any statesman compatible

modules in the connected frame or frames and display them in the left hand explorer-style

window of the main application.

Open any frame by clicking on the ‘+’ sign or by double clicking on a frame. Installed

modules should be shown with module icons. Frame and module icons can be named as

desired by right clicking or using the edit menu and choosing rename.

To aid user recognition of module and frame status quickly, the following colour and size

coding is used:

•A module is shown present by full colour and absent by greyed colour

•A module is shown open by large icon size and closed by small icon

•A module is the source of an active alarm if red and not alarmed if green

Double-clicking on a module will enable the display of the main application menus.

Statesman main application window

The two large control panes shown in the upper and lower halves of the window may

display different menus for the same card, or controls for different cards. Click on the

horizontal button-bar between the two panes to close the lower plane or drag the button to

vary the size of the panes.

3.1 Video status and settings

The VDA 210 Control tab provides access to the following

•Variable gain for each channel

•Variable equalisation for each channel

•Input status/error status/standard for each channel

•Source select

•Second channel type select

VDA210R Control tab

Gain

Video gain may be varied in gain in 0.025dB steps from 70% (–3.0dB) to 140% (+3.0dB)

using the slider provided. Press the CAL button to restore unity gain.

Equalisation

Cable loss compensation may be varied in 1.2m (4 feet) steps from zero to 300m (0 to 984

feet).

Press the CAL button to restore the default of zero equalisation.

Status indicators

Ind Colour Meaning when lit

Inp Presence Green Composite / Y + sync / Green + sync input signal present.

Sync Error Yellow Input sync size <90% or >110% of expected value.

Luma Over Yellow Output Luma levels >110% of peak white

Luma Dark Yellow Output Luma level <15% of peak white for time delay set by

rotary Delay control

Input standard select

Although the input standard is detected automatically, it may help to match the on-board

video content error detection with the precise input video standard. Use the Input standard

check boxes to select the standard that matches the actual input present.

Std Default Alternatives

625 PAL-B, -G, -H or -I. PAL-N or PAL-N (Argentina).

525 NTSC-M PAL-M or NTSC-M (Japan).

Source select

The VDA210R can be operated in two modes:

•2 x 5 – dual channel mode; seconds channel uses Input 2 as source

•1 x 10 – single channel mode; second channel uses Input 1 as source

To change mode check either Input 1 or Input 2 as the source for Channel 2.

Note: The second channel input will not appear at the output when Channel 2 uses Input 1 and

Input 2 status indicators will be greyed out.

Second channel type select

The Channel 2 CBRUV check box is provided to allow the on-board error detection and

output clamp to be matched with the input 2 video format.

If the CBRUV box is left unchecked a composite video, Y + sync or G + sync input is

assumed. In this case, input error status reporting is activated and the output clamp uses

the sync pulses on input 2 to DC-restore output 2.

If the CBRUV box is checked, a chroma input is assumed. In this case channel 2 error

detection is disabled and the output clamp uses the sync pulses on input 1 to DC-restore

output 2.

Note: The second channel input type box is not greyed out even when Input 2 is not used to

contribute to any outputs.

3.2 Setting alarm/clamp options and recalling

factory defaults

The Misc tab provides access to the following:

•Alarm on black on/off/delay

•Clamp – fast, slow, off

•Set defaults – Cal All

VDA210R Misc tab

Alarm on black

Use the rotary control to adjust the delay time after which dark (<15% Luma) picture

content sets an alarm. The delay is adjustable in 1 second steps from 1 second to 10

minutes. Check the Off box to disable the dark alarm and the corresponding GPI output.

Output clamp

Check an appropriate clamp option.

Fast provides a recovery time of approximately 6 lines. Slow provides a recovery time of

approximately 60 lines. Off selects an AC-coupled output.

Cal all

Click on Cal All to clear all user adjustments and set the VDA210R to factory defaults.

Note: For further details of Statesman configuration and operation please refer to the Statesman

manual.
