2.2 X-ray interface box
The X-ray interface box monitors the statuses of the X-ray generator and detector to control the
X-ray exposure and imaging. It consists of the PCA-XIF board, AC adapter, X-ray interface
cable, grounding wire and covers. Even when a multiple number of detectors are in use, only
one detector per X-ray interface box can be specified from the image capture computer to take
images.

In the imaging sequence described below, the items printed in bold represent the control
operations performed by the X-ray interface box.
(1) The user presses the exposure switch.
(2) The
exposure enable request signal from the X-ray generator is monitored by the X-ray
interface box .
(3) The X-ray interface box makes an Enable judgment for the exposure enable request
signal , and sends the trigger signal to the detector.
(4) When the imaging preparations of the detector are completed, the imaging enable signal is
sent from the detector to the X-ray interface box.
(5) The X-ray interface box monitors the imaging enable signal from the detector.
(6) The X-ray interface box makes an Enable judgment for the imaging enable signal , and
sends the exposure enable signal to the X-ray generator.
(7) With the detector now in the imaging status, X-ray exposure is commenced.
(8) When the detector has finished imaging, the images are transferred to the image capture
computer.
(9) This completes the imaging sequence.
