I think you are correct. Below is my e-mail from 11/21/2009. I was
under the impression that the documentation had been changed to
correct the inconsistency back then but apparently not.<br>

<br>
The connection diagram on page 5 of the Pennywhistle Assembly and
Operating Instructions document shows the 3-pin header numbers with
1 labeled as Bias Control and 2 labeled as ground. <br>
This appears to be at odds with the schematic which shows 1 ground
and 2 Bias Control.
<br>
<br>
Since tests with my ohm meter agree with the schematic, it appears
that the connection diagram is incorrect.
<br>
<br>
The last thing I have to do is wire up the control cable to this
header and the DB25 - want to make sure I have it correct.

<div>I did a search of e-mail that I have - not exhaustive by any
means - but has anyone noticed that the Bias Control and Ground
Pin numbers are reversed in the below diagram? (please see
PennyWhistle connection diagram in the pdf on the web-site)</div>
