Input / Output Cards 
12-Channel Video Input Card (ES3311-2) 
The ES3311-2 Input Card allows external analog video sources to be digitized and used by the 
VN-QUANTUM Processor. 
Each card has 12 source inputs which can be used with either composite video or s-video sources. 
Full auto-detection is provided on each input, allowing a wide range of standard source types to be 
connected without the need for any further configuration. 
The maximum number of ES3311-2 cards that can be installed is limited only by the number of 
available card slots (see table on page 57). With the minimum of one Output Card fitted: 
  The ES3301-2 Card Frame can accommodate up to 14 Input Cards, 
allowing a maximum of 168* video source inputs. 
  The ES3302 & 3304 Card Frame can accommodate up to 7 Input Cards, 
allowing a maximum of 84* video source inputs. 
*The maximum number of video sources that can be displayed simultaneously is determined by 
the rectangulation limit of the Output Cards (for further details see page 74). 
For full technical details on the ES3311-2 card, see page 99. 
2-Channel RGB Input Card (ES3312) 
The ES3312 Input Card allows external analog RGB graphics sources or HD Video sources (in RGB 
or component YPrPb format) to be digitized and used by the VN-QUANTUM Processor. 
Each ES3312 card has 2 source inputs which can be used with either analog RGB or component 
YPrPb sources. Full auto-detection is provided on each input, allowing a wide range of standard 
source types to be connected without the need for any further configuration. 
The maximum number of ES3312 cards that can be installed is limited only by the number of available 
card slots (see table on page 57). With the minimum of one Output Card fitted: 
  The ES3301-2 Card Frame can accommodate up to 14 Input Cards, 
allowing a maximum of 28 RGB/HD source inputs. 
  The ES3302 & 3304 Card Frame can accommodate up to 7 Input Cards, 
allowing a maximum of 14 video source inputs. 
For full technical details on the ES3312 card, see page 101.
