LBC Hold Button
LBC Hold Button
In the parlance of the PDP days, clicking on Hold (and then of course
on the appropriate Start button) is the equivalent of
"99ing" the bench. The light goes to that bench and stays there,
signalling the Host computer as quickly as every
one second, that it is ready for another picture. Since most cameras take
over a second to recover from taking one picture before it can take
another, this is equivalent to taking pictures as fast as possible. There
are actually three different ways to hold the light on a given bench:
- Use the hold button as described above - as long as there is a Host computer, it will take pictures as rapidly as it
can.
- Turn all other benches off and make a one bench cycle - the interval
between pictures will now be determined by the Cycle Time set
for that bench.
- Turn every bench off to the left of the desired bench and Stop the cycle - the "resting" position of the light
after the cycle has been stopped is the left-most selected bench on the
GUI. So, if all benches are selected, it would be the the 26E1 and the 10E
on the 26" and 10" telescopes respectively. Since the cycle has been
stopped, there will be no communication to the host computer and no
pictures will be taken.
Remember, before the light can go to a Host-controlled
bench, the host must signal it is ready to receive the light. If this is
not the case, you can always work around this by setting the Host to None before selecting Hold.
Once the Hold has started, you can restore the old settings by clicking
again on Hold, or by pressing the Resume button,
which temporarily replaces the Restore button during a Hold. You can also
just start turning desired benches on and off using the Bench Select buttons or go directly to Holding
on another bench by clicking on its Hold button.
