Cronologic Reveals PCIe Expansion Box with Front Access
Most PCs only includes a few PCIe slots. The brand new Ndigo Cage from cronologic GmbH & Co. KG allows to improve this quantity by up to seven boards within an external chassis. That is specifically useful in data acquisition applications that aggregate many stations or use a variety of boards to accumulate many types of data. The enclosure was particularly designed to home up to eight of cronologic’s Ndigo5G-10 digitizers for a complete of 32 channels working at up to 5 Gsps each, nonetheless it is equally perfect for other applications that require even more PCIe boards in one PC than usual. Powerful computing users for instance could squeeze a lot more than 14000 dual precision GPU shaders models in one PC.
The communication between sponsor and extension is implemented using PCIe-over-cable for a price of 16 lanes PCIe2 for a complete of 80Gbps in each direction. That is eight times the overall performance of a thunderbolt connection.
The usage of PCI express as a protocol gets the convenient consequence that the extension is managed entirely by the BIOS with no need of a software driver. An operating-system can’t distinguish a table housed in the expansion box from a table connected to the PC mainboard.
However the unique feature of the Ndigo Crate is that the table connections are available from leading side of the package. “In DAQ applications you have to be capable to start to see the position LEDs all the time.” says cronologic’s CEO Kolja Sulimma. He adds: “Within an experimental set up the Ndigo Crate enables the operator to quickly change cable connections with no need to crouch behind tables”. The Ndigo Cage is currently available with eight PCIe2 x4 slots. In Q3/2012 another edition of the cage will follow that facilitates PCIe3 x8 slots and in addition offers two legacy PCI slot machines. This enables the crate to do something as a PCIe to PCI adapter. Specifically it enables an individual to produce systems that make use of cronologics HPTDC8-PCI period to digital converters synchronized to a Ndigo PCIe digitizer.
