MECHANICAL
Standard Crystal Vision module 266mm x 100mm
Weight: 180g
Power consumption: 9.5 Watts

INPUTS
Three SDI inputs (Foreground, Background and Key)
SDI 270Mbit to EBU 3267-E and SMPTE 259M
Cable equalisation >200m Belden 8281 or equivalent
Auto 625/525 line selection
Reference timing can be selected to come from Foreground, Background or Key input
Delay through board: 15 us approx.
Max input buffer length two lines (selectable)

OUTPUTS
Maximum of two main and two auxiliary SDI outputs (two main and one auxiliary output using the RM01 and RM42 frame rear modules and two main and two auxiliary outputs using the RM18)
Active loop-through output for Background with RM18
The RM42 provides relay bypass portection. An electromechanical relay switch needs power to hold the switch in one state and will revert to the other state (board bypass) on loss of power. It prevents signal loss by mechanically connecting the Background to main output 1 on complete frame power failure or board removal
SDI 270Mbit to EBU 3267-E and SMPTE 259M with EDH
Will drive >200m Belden 8281 or equivalent
Main and auxiliary outputs can be used to show Main Output, Preview Foreground, Background, Key, Processed Key or Matte Generator
Auxiliary outputs can show combined picture when main output has been faded to Background, or faded to black

KEYING MODES
Foreground and Background can be mixed, wiped or keyed
Wipes include: horizontal, vertical, horizontal blind, vertical blind, left corner, right corner, box and cross. Can be triggered manually or automatically
Key processing can be additive or multiplicative. Additive keying is only required with some caption generators where the Foreground is already processed
Separate Foreground Force and Background Force internal rectangular masks can be combined with external keys in multiplicative (standard) keying
Internal colour matte generator can be used as a fill for keying
Self-key is available from Foreground input
Adjustable key gain, offset and inversion
Key fade function, to fade Foreground in and out. Manual or automatic - auto key fade time can be set to take from 0 to 100 fields
Main outputs have fade to black, available in all modes. Manual or automatic - auto fade to black time can be set to take from 0 to 100 fields

ANCILLARY DATA/EMBEDDED AUDIO
Ancillary data and embedded audio is taken from Background input and inserted to main outputs

GPI INPUT LEVELS
Electrically: Will tolerate 0V to 30V, pulled up to +5V through 1 kohm

GPI INPUTS
Up to four momentary or two level control GPI inputs available (or first four can alternatively be link selected to be RS422 for use with the Safire Controller, for example)

First four are momentary control and will do the following:
GPI0: Fade key up or fade key down
GPI1: Mix from Foreground to Background or from Background to Foreground
GPI2: Wipe from Foreground to Background or from Background to Foreground
GPI3: Fade to black or fade from black

GPI4 and GPI5 are level control GPIs:
GPI4: When level is zero the key will fade down. When level is high the key will fade up
GPI5: When level is zero will fade to black. When level is high the normal programme will be output

REMOTE CONTROL
RS484 multi-drop 19200 baud, 8 bits, no parity
Safire Controller control panel operates up to seven LKEY211 modules
Statesman software allows control from any PC on a network
SNMP monitoring and control available as a frame option
Up to ten presets may be stored and recalled
