Grounding change for improved resistance toUSB
communication failures June 15, 2011
To improve theUSBA/D board’s
resistance to communication
losses it appears to be helpful to
ground themetal shell of theUSB
jack on the 302 and 333A/D
boards.
Solder a 1000ohm1/2watt resistor
directly to the shell of theUSB jack
on the 302 or 333A/D board.
Shrinkwrap over the resistor and
wire.
Connect thewirewith a ring termi-
nal to chassis ground stud.
