A clientadapter is plugged into the upstream port of a backplane (Gen2 or Gen3) and via the host adapter it is connected to a free PCIe slot in the host system.
The clientadapter X8 supports 8 PCIe Gen3 lines which are connected via 4 Mini Displayport cables (2 lanes each) to the host adapter.
A jumper can be used to select whether the cabling is inside (e.g. Case #2) or outside (Case #3, Case #4) of a case.
With DigitalDevices cables, the optimal setting in the host and client adapters is done automaticaly.
Cable length from 0,5 – 7 m is possible.
There is a Low Provile and a Full Provile slot bracket available.
| Achievable data rates | Cable 1 | Cable 2 | Cable 3+4 |
| PCIe Generation1 | 5 Gbit/s | 10 Gbit/s | 20 Gbit/s |
| PCIe Generation2 | 10 Gbit/s | 20 Gbit/s | 40 Gbit/s |
| PCIe Generation3 | 16 Gbit/s | 32 Gbit/s | 64 Gbit/s |
Note: the PCIe specification only provides for PCIe x1 as a mandatory fallback option.
