PXH812 Operating Modes
The Dolphin PCI Express PXH812 card is a transparent PCI Express Gen3 cable adapter card. The card supports
both upstream host and downstream target operation. The operation is controlled by the TRANSP and TARGET
DIP switches that can be found close to the upper edge of the board. The main
configuration options are found in the table below. The shipping default is
Transparent Host mode. To enable Transparent Target mode, DIP switch TARGET
needs to be set. In Transparetn Target mode, the NTB-LED will be orange. For both
modes, OPT2 can also be set to tune the card for long cables –this is typically
required for 3-5m (10-16ft) copper cables.
