KDSP2 problem

[Mike Geddes]

Installed the KDSP2 module in my K2 this morning.  During initial checkout,
the LED light does not come on upon power up, or at any other time. The
other steps on the initial checkout (p.18) seem to be working as specified.
What does it mean when the LED does not come on?  Is there any particular
thing I should be checking or looking for?  Is it possible that the module
is defective?  I double checked the connections to make sure the KDSP2 board
was inserted into the control board jumpers correctly, and that the DSPx
module was inserted in the KDSP2 board correctly.

Any suggestions are appreciated.

Tnx and 73,

Mike

Mike,

If the KDSP2 seems to be working properly, I must ask about the
possibility of the LED being reversed.

Shine a light on the top of the KDSP2 and look carefully at the LED -
near the base you will find some reflective metal through the colored
lens - there is a narrow wedge in that metal.  If the wedge points
toward the connector, the LED is mounted correctly, but if it points
toward the edge of the board, it is mounted backwards.
