Datapath Vision800X - Manual (Page 4)

When connecting a Vision800X expansion chassis to a Vision800 machine the H-Link card in the Vision800
must be installed into the x8 slot. The S-Link card in the Vision800X should be installed in the PICMG1.3
SBC slot.
Connect the H-Link and S-Link cards using the Ex-Cable as shown in the illustrations on the previous page.
Gen-locking Cables on H-Link and S-Link Boards
Connectors J4 and J5 are used for Gen-locking multiple chassis together. This is useful when using multiple
chassis that each contains a number of Datapath Image4 graphics cards. The gen-locking chain is used
to tie the outputs of the graphics cards together so that they all render their outputs to the screen at the
same time. This makes fast moving images appear smoother on the video/data wall and eliminates ‘tear-
ing’ artefacts on the display.
To create a gen-locked chain using the H-Link and corresponding S-Link cards, firstly ensure that the sys-
tem is powered down. Then connect the gen-lock output of the closest Image4 graphics card to connector
J4 (GEN LOCK IN) on the H-Link board using the cable supplied with your H-Link board, as shown in the
illustration below. Note that this cable is longer than the cable supplied with each Image4 graphics card
in order to cover the extra distance between the Image4 and the H-Link board. This will send the gen-lock
clock over the Ex-Cable to the next downstream chassis.
