Wall Sizes vs devices table

Here follows a table which specifies the number of Split16s needed to obtain a particular wall size. Note that some wall sizes may have different possible configurations; in the table you will find only the configurations which employ the minimum number of splitters. Magnifications are specified by width x height of the wall in displays.

Common set ups

• 6x4, 2 devices

  1/1	2/1	3/1	1/2	2/2	3/2
  5/1	6/1	7/1	5/2	6/2	7/2
  9/1	10/1	11/1	9/2	10/2	11/2
  13/1	14/1	15/1	13/2	14/2	15/2

6x4 walls are one of the most common wall configurations; this format has a widescreen format and allows with only two devices to have two video sources on the same wall, giving impressive results.

• 8x4, 2 devices

  1/1	2/1	3/1	4/1	1/2	2/2	3/2	4/2
  5/1	6/1	7/1	8/1	5/2	6/2	7/2	8/2
  9/1	10/1	11/1	12/1	9/2	10/2	11/2	12/2
  13/1	14/1	15/1	16/1	13/2	14/2	15/2	13/2

like 6x4, the 8x4 walls are one of the most common wall configurations; this format has a widescreen format and allows with only two devices to have two video sources on the same wall, giving impressive results.

• 5x5, 3 devices

  1/1	2/1	3/1	4/1	1/2
  5/1	6/1	7/1	8/1	5/2
  9/1	10/1	11/1	12/1	9/2
  13/1	14/1	15/1	16/1	13/2
  1/3	2/3	3/3	4/3	5/3

  5x5 walls are made with 3 devices; this is one of the most disadvantaged formats since most of the outputs get unused; it's suggested to use 6x4 or 6x6 walls, which are made up respectivly of 2 and 3 splitters and have almost the same number of displays.

• 6x6, 3 devices

  1/1	2/1	3/1	4/1	1/2	2/2
  5/1	6/1	7/1	8/1	5/2	6/2
  9/1	10/1	11/1	12/1	9/2	10/2
  13/1	14/1	15/1	16/1	13/2	14/2
  1/3	2/3	3/3	4/3	5/3	6/3
  9/3	10/3	11/3	12/3	13/3	14/3

  6x6 walls need 3 devices; some different configurations can be made to satisfy the customer's need: the first shown allows to have up to three sources, with the ability to work with a single big image or a 4x4 image and a frame of 2x2 videos. This is one of the most commond and easy 6x6 configuration.

  1/1	2/1	3/1	1/2	2/2	3/2
  5/1	6/1	7/1	5/2	6/2	7/2
  9/1	10/1	11/1	9/2	10/2	11/2
  13/1	14/1	15/1	13/2	14/2	15/2
  1/3	2/3	3/3	5/3	6/3	7/3
  9/3	10/3	11/3	13/3	14/3	15/3

  The second configuration suggested allows to have the maximum resolution in the 6x6 magnification (using 'number of columns' of 3 in the control software). This configuration also allows the user to display multiple video sources on the same wall by selecting different inputs for the three devices. Note that it's possible to switch between the inputs of each device remotely using the control software.

1/3	2/3	3/3	5/3	6/3	7/3
1/1	2/1	3/1	1/2	2/2	3/2
5/1	6/1	7/1	5/2	6/2	7/2
9/1	10/1	11/1	9/2	10/2	11/2
13/1	14/1	15/1	13/2	14/2	15/2
9/3	10/3	11/3	13/3	14/3	15/3

A third configuration can be used to form a frame of monitors on the top and the bottom of the wall, which allows singles or color wash to be added to two 3x3 walls with different video sources or a widescreen 6x3 single image video.

• 7x7 / 8x8, 4 devices

  1/1	2/1	3/1	4/1	1/2	2/2	4/2	3/2
  5/1	6/1	7/1	8/1	5/2	6/2	8/2	7/2
  9/1	10/1	11/1	12/1	9/2	10/2	12/2	11/2
  13/1	14/1	15/1	16/1	13/2	14/2	13/2	15/2
  1/3	2/3	3/3	4/3	1/4	2/4	3/4	4/4
  5/3	6/3	7/3	8/3	5/4	6/4	7/4	8/4
  9/3	10/3	11/3	12/3	9/4	10/4	11/4	12/4
  13/3	14/3	15/3	16/3	13/4	14/4	15/4	16/4

  7x7 and 8x8 walls can be made with 4 devices; the common configuration is the one show here which, in the case of the 7x7 have to be reduced by taking away the last row and the last column.

High resolution formats

Split16 has the capability of working in high resolution mode for 2x2,3x3 and 4x4 magnifications. this mode allows the device to process the image with double the horizontal magnification, which produces images with smaller pixels and very high detail, needed for example with high bandwidth sources like scan converters and broadcast quality videos.

To obtain high resolution modes you have to keep in mind that while 2x2 needs only one device, 3x3 and 4x4 need two devices, which produce in turn the first two rows and the second two (the third row in the case of 3x3). You can find in the user hardware manual the correct dip switch setting.

Driving multiple walls with one splitter

Split16 was designed with current drive Digital to Analog Converters (DACs), which allow the outputs to be connected to 2 x 75 ohm terminated displays maintaining the video output level at the standard 1 Vpp level.

A third display can be connected with a small loss of signal amplitude to drive up to three walls to just one splitter!

To connect multiple displays to the same output a y cable adaptor is needed (order code SP16VCY); this adaptor is simply a 1 input / 3 output cable splitter which connects in parallel the 3 displays.

Circular videowalls with the Roll function

With a single Split16 It is possible to drive a 9x3 / 9x4 circular videowall, made with tower displays available from many manifacturers (Avialec,Hantarex-Sambers, Sèleco, Selti). This kind of installation can be reduced to 8x4 / 8x4 to allow an access to the center of the circular wall (with 9 displays the circle si completely colsed, and the center inaccessible).

The Roll function of the Split16 was especially designed for this kind of configurations, allowing the image to slide from right to the left, thus rotating across the circle and showing the complete image in all of the viewing directions.

No external controller is needed to use this function, since it can be switched on by using the functions dip switch.

!!! Note that the roll function won't work on high resolution formats !!!
