Disable Expose_OK Input Signal
Disable_Expose_OK is a system integrator driven signal to the detector. Disable_Expose_OK
allows the integrator to control when Expose_OK is issued from the detector. When
Disabel_Expose_OK is enabled, Expose_OK cannot be ON. This signal can be used to ensure
dark frames are captured before an exposure or to block X-ray in a fault state.
The detector's Disable_Expose_OK input is present on pins 6 and 7 of the male 9-pin D-sub,
shown in
Table 17 on page 28
and
Figure 7, on page
28. The detector input circuit is shown in
Figure
10.
Connect the positive signal to pin 6 and the negative to pin 7. Applied voltage should be between
5 V to 15 V, corresponding to approx. 6 to 25 mA input current. If no voltage is present or if the
input is left unconnected, Expose_OK is enabled.
