Lynx Genie 2000 Acquisition Window Adjust
Lynx DSA User's Manual - 9240227J 55
If acquisition has been deferred as result of the “Changer is Ready” condition not
having been met, then Genie’s acquisition status will be reported as “Wait” instead of
“Busy”.
Selection for Ready and Advance must be made according to the hardware
requirements to which the Lynx’s sample changer is being interfaced to.
Advance
Used by the Internal Chgr sample changer selection. Controls the DC quiescent state
of the rear panel’s CHGR ADV sample changer advance output signal as well as the
polarity of the advance pulse transition. An advance pulse will be produced when a
Changer Advance command is received through Genie’s manual or batch control.
Pulse width is always 150 milliseconds. Positive selects a TTL-low quiescent state
and produces a TTL-low-to-high pulse. Negative selects a TTL-high quiescent state
and produces a TTL-high-to-low pulse.
Selection for Ready and Advance must be made according to the hardware
requirements to which the Lynx’s sample changer is being interfaced to.
