NOTICE REGARDING SILKSCREEN LABELING ISSUE
------------------------------------------

Certain versions of the TF-eSATA-FE-ZP test fixture have a mistake in
their silkscreen labeling: the "HT" and "HR" signal pairs' labeling is
swapped.  Note that the labeling problem does not affect the products'
functionality.

The correct signal identifications, regardless of what the silkscreen
labeling indicates, may be determined as follows.

When looking into the front end of the eSATA connector, first determine
whether the horizontal "bar" in the opening is closer to the bottom
side of the connector (that portion which makes contact with the printed
circuit board (PCB)), or whether it is closer to the top side of the
connector.

For test fixtures having eSATA connectors whose bar is closer to the
bottom side of the connector, the actual signal identifications from
left to right (while looking into the front end of the eSATA connector)
are: HR+, HR-, HT-, HT+.

For test fixtures having eSATA connectors whose bar is closer to the
top side of the connector, the actual signal identifications from left
to right (while looking into the front end of the eSATA connector) are:
HT+, HT-, HR-, HR+.
