Installing the Additional XtremeVision-Pro+ Cards
As the number of required screens increase, the likelihood of reaching a system limitation or encountering a problem increases.
The system limitations are the amount of address space available and the capacity of the power supply.
Please consult EMS support if you have any problems installing multiple cards.
Power
The amount of current a power supply can deliver on each voltage rail is limited. Often there is also a limit on the total power.
Each XtremeVision-Pro+ card requires 0.25A at +3.3V and 1.2A at +12V.
You can calculate the amount of current and the amount of power required for the XtremeVision-Pro+ cards. For example, the
requirements for a 16-
SCREEN
system of XtremeVision-Pro+ cards are calculated as follows:
Current
+3.3V 4 x 0.25A = 1.
O
A
+12V 4 x 1.2A = 4.8A
Power
( 3.3V x 1.0A ) + ( 12V x 4.8A ) = 60.9W
These are just the requirements for the XtremeVision-Pro+ cards; you must take into account the requirements of all the other
devices in the system.
