Asynchronous Trigger Mode of the JAI M10 BX
Question
What is the difference between H-reset and H-Non-Reset of triggering
asynchronously the JAI M10 BX?Answer
The JAI M10 BX features two external asynchronous trigger modes: Edge
Pre-Select and Pulse Width Control. Both modes may be used in either
H-Reset or H-Non-Reset mode, which are slightly different:1. H-Reset
Mode:In H-Reset Mode the internal HD is being reset with the falling edge of
the trigger pulse; after that, exposure starts without further delay. 2.
H-Non-Reset:Exposure does not start immediately, but is latched to the HD
pulse following the falling edge of the trigger pulse. Therefore the exposure
start may have a delay of up to one HD (64µs) relative to the trigger pulse.
Additionally, in Pulse Width Control mode the actual exposure time may vary by
up to 1 HD, which, however, is hardly noticed if the exposure time is
significantly longer than 1 HD.The JAI M10 BX up to Rev. D only supports HReset,
wherease Rev. F features both modes.
