ESCRIPTION
Characteristics:
• Manual interface
• Potter Bucky Potentiometres interface.
• Vertical Focus-Film distance interface (FFD/SID) with potentiometers related to
table and stand.
• Interface with 5 fixed lateral distances.
• Interface for general controls; e.g., open/close for shutters, tomography. See the
specifications regarding this point described in this chapter.
Description:
Board ASR003 is an extension of the radiological system. It provides interfacing with
the collimator which features board CAN DC STEP and analogic signals coming from
other system devices.
It operates via CAN BUS with a Ralco proprietary protocol.
The user end features 32 digital inputs, 8 analogic inputs and 10 relay outputs.
So as to adapt to different devices, digital inputs are fixed for optioinsulation so as to
allow connection also with devices that supply output control voltages (typical range
12-32 Vdc).
Since the input signal sometimes comes from a voltage-free contact, the board fea-
tures a number of pins to which an external supply may be connected. Alternatively
these pin may be connect to a voltage incoming from board ASR003 itself by simply
connecting pin M79 to pin M80 and pin M81 to pin M82.
The available voltage is not taken upstream of the voltage regulator but downstream of
the fuse and rectifiers bridge.
The type of software applied determines the function of each input.
