Connecting a VSN900X-Optical Expansion Chassis

The Optical Solution

The Datapath optical solution allows expansion chassis to be located up to 100m away from the main  
controller.  The Optical solution can support up to PCIe Gen 3 x8  bandwidths between an HLink-Optical,  
located in the host machine and an SLink-Optical, located in the expansion chassis  Full bandwidth is 
achieved by using two ExCable-Optical cables between each HLink and SLink-Optical card .  

Alternatively, PCIe Gen3 x4 bandwidth can be achieved using only one ExCable-Optical between each 
HLink-Optical and SLink-Optical.  This will reduce the total amount of video signal that can be transferred 
between the chassis.  If x4 bandwidth is acceptable, one HLink-Optical can be connected to two  
SLink-Optical cards, providing that the HLink-Optical is located in a x8 slot.  

See 

Creating the link x4 and x8

 on page 15.

If your optical expansion chassis is supplied as part of a complete wall controller system the HLink-Optical 
card will be pre-installed in the host machine which contains the SBC. If the expansion chassis has been 
supplied separate to a host machine the HLink-Optical card provided needs to be installed in the host PC.

You are likely to need a flat blade and/or a cross head screwdriver for the installation of the HLink-Optical 

card; it would be useful to have these to hand before you begin. Power down the PC (including  

peripherals), switch off at the mains and disconnect all the cables connected to the computer and 

 

expansion chassis. Remove the PC cover. Locate a vacant PCIe slot (x8 on the motherboard and remove 
the backing plate (retain all screws) .

Remove the HLink-Optical card from its packaging and secure it firmly into the empty PCIe slot. Screw the 

bracket to the back panel of the PC and replace the cover.

Connect the HLink-Optical and SLink-Optical using the ExCable-Optical provided. If more than one  
expansion chassis is supplied, ensure the cards are paired correctly by connecting the cards labelled 
“Link1” together, the pair labelled “link2” are connected together and so on. In the event that this is not 
possible i.e. the expansion chassis are shipped separately and the cards are not labelled, connect the cards 
using the ExCables-Optical provided and re-install the Datapath Driver Install package to reset the  
pairings.

PCI Express Gen.3 technology supports one directional data transfer speeds of up to 8GB/s of raw data 

(6.4GB/s effective data rate) ensuring smooth, full frame rate video distribution over great distances. 

Connecting to a VSN970/VSN990 Wall Controller

If the VSN900X-Optical is being connected to a VSN970 or VSN990 and the full bandwidth (x8) is required 

then dual optical cables should be used and the “Daisy Chain” configuration adopted.  This is achieved by 
installing the HLink-Optical card on the first slot of the VSN970/VSN990 and the first slot of each 

 

subsequent VSN900X expansion chassis.  Only the first slot of the Express9-G3 backplane is able to 

 

support the full x8 Gen.3 connection.  Using other slots on the backplane or adopting a “Star”  

configuration i.e. a single HLink-Optical in a host system connected to 2 x SLink-Optical in separate 

 

expansion chassis will still work but at a  reduced bandwidth (x4).
