<DIV><FONT face=Arial size=2>A four position rotary switch would take up
four button inputs (key presses) on your interface controller
(EPIC). A six position switch, six button inputs. Hairy code
would be required to detect one detent moves in either direction.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>OTOH... </FONT><FONT face=Arial size=2>A rotary
encoder would only send two different key presses to your interface controller,
no matter how many actual positions (detents) it has: one for a clockwise
turn of one detent and one for a similar counterclockwise turn.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Another way: A rotary switch only sends (makes) key
presses. It's dumb. A rotary encoder is smart - it knows which way
it's being turned, and sends the key press appropriate for the direction of
turn.</FONT></DIV>

Virtually any knob in your pit that you turn to make adjustments (as opposed
to a potentiometer that you would turn to adjust volume or brightness) such as
a radio tuner, HDG or OBS knobs, the Kohlsman knob on the altimeter, the
course, speed and altitude setting knobs on the autopilot, transponder code
selector, etc etc etc would all be rotary encoders.
<BR><BR> There are alternatives such as
Knitter switches, but as a general rule, anything you want to be able to 'dial
in' needs to use a rotary encoder.<BR><BR>Richard </SPAN></FONT><FONT
