Detailed Setup Instructions
Set Up the Hardware
1
Daisy chain the graphics cards together using a standard CAT5 patch cable plugged
into the external RJ45 connector.
•
You can connect to any of the two RJ45 connectors located on the graphics card
bracket.
•
Each connector automatically configures itself as an input or output after all the
connections are made and one system is configured as a synchronization server (see
“Set Up the Server” on page 15
). A flashing green LED indicates an input and a
flashing yellow LED indicates an output.
If there is no server assigned and connected, then both LEDs are a steady green.
WARNING!
The voltage and signal on the frame lock ports are different from Ethernet
signals.
Do not connect a Frame lock port to an Ethernet card or network hub.
Doing so
can cause damage to the hardware.
2
Designate one of the cards to be the server device. The remaining cards are client
devices.
The server determines the trigger pulse for the client devices. The trigger pulse is
derived from the V-sync of the server video.
