Installing VisionSwitch With The iH4 Card
The Datapath VisionSwitch is connected to the iH4 cards via inter- card ribbon cables, enabling the
iH4 video overlays to select 1 of 16 possible video sources. The VisionSwitch supports up to four
iH4 cards.
Install and configure all iH4 cards in the system, carefully following the iH4 installation instructions.
Ensure that your multi- screen system is working correctly before installing the Vision Switch.
Install the VisionSwitch carefully following the installation instructions provided.
Once the VisionSwitch is installed it can be connected to the iH4 cards.
You will need to determine the ordering of the iH4 cards to enable the correct connection. The
example below displays four iH4 cards configured as a 4 x 4 monitor video wall. The ordering in
this example is the iH4 (1), the Master iH4 card always drives the first four screens, in this case the
top four. The second iH4 drives the next four, and so on. Count the screens starting from the top
left of the video wall and then across from left to right:
Once the order of the iH4 cards has be determined, connect the ribbon cables as follows:
1st iH4 (Master) (J3) To VisionSwitch (Output 1-4) (J6)
2nd iH4 (Slave) (J3) To VisionSwitch (Output 5-8) (J7)
3rd iH4 (Slave) (J3) To VisionSwitch (Output 9-12) (J8)
4th iH4 (Slave) (J3) To VisionSwitch (Output 13-16) (J9)
The diagram below is for illustration purposes only and the particular sequence of the iH4 cards in
your machine will not necessarily be the same.
