The action of the positive (rising) edge depends on the function: For
the
START-CONTINUE
function, the rising edge has no effect. For the
TRAY TEMP ON/OFF
function, the rising edge turns off sample
temperature control.
•
Inverted Edge : The inverted
edge mode works identically to
the normal edge mode except
that the positive and negative
edges are reversed in function.
•
Normal Pulse : In normal pulse
operation, the negative (falling)
edge of the TTL signal is the
active edge and the positive
(rising) edge is ignored.
A pulse width of 50 ms or more is guaranteed to be detected. A pulse
width of 4 ms or less is guaranteed to be ignored. The action for pulse
widths that are greater than 4 ms and less than 50 ms is undefined.
•
Inverted Pulse : The inverted
pulse mode operates identically
to the normal pulse mode
except that the positive and
negative edges are reversed in
function.
