Introduction Test Modes
1-4 E2969-91020
Known Endpoint Test Mode
In the Known Endpoint test mode, the PTC behaves like a known
endpoint device.
This mode is used for system testing. No other card can be plugged into
the PTC in this mode. The software runs various KEP tests to test the
systems behavior on certain error conditions.
The KEP mode will be supported by one of the next software releases.
Topology Mode
The Topology mode is used to test BIOS settings.
Controlled by software running on an external host connected through
USB, the PTC pretends to behave like a variety of PCI Express devices. No
other card can be plugged into the PTC in this mode.
All configuration accesses are handled via the software connected
through the USB link. No other accesses or transactions are supported in
this mode.
In this mode it is necessary to power the PTC through the external power
connector. Any standard ATX Power Supply can be used for this purpose.
