Signal Description
Injecting
Output signal to Imaging System that shorts pins 1 and 2 together when
the system is injecting. When not injecting, pins 1 and 2 are open.
Extended_Arm
Output signal to Imaging System that shorts pins 3 and 4 together when
the system is armed. When not armed, pins 3 to 4 are open.
Handswitch Disable
Input signal from Imaging System; when pins 5 and 6 are shorted, the
injector hand switch and/or foot switch is disabled from directly initiating
an injection. When open, the injector hand switch and/or foot switch
functions normally.
Remote Start
Input signal from Imaging System; when pins 7 and 9 are shorted, the
injector is commanded to start the injection.
Remote Disarm
Input signal from Imaging System; when pins 8 and 6 are shorted, the
injector is commanded to disarm.
X-Ray Trigger
Output signal to Imaging System that shorts pins 10 and 11 together when
active.
Gate Out
Output signal to Imaging System that shorts pins 12 and 13 together
based on an ECG R-wave signal. This signal will not be used in the
Mark 7
Arterion design and is only presented for informational purposes.
Handswitch closed
Output signal to Imaging System that shorts pins 14 and 15 together as an
indication that the
Mark 7 Arterion hand switch or foot switch is pressed.
