OVERVIEW
C-ARM CONTROL
This section describes how the following circuit boards and components control
the C-Arm.
• Technique Processor PCB
• Analog Interface PCB
• Control Panel Processor PCB
• Control Panel Processor I/O PCB
The Technique Processor PCB is the controlling circuit board and the Analog
Interface PCB is the slave. The Control Panel Processor PCB serves as an input
/ display liaison for the two control panels and vacuum fluorescent displays
(VFD) used by the operator of the system.
When a switch closure is made at either of the two control panels, it is encoded
by the Control Panel Processor which sends this information to the Technique
Processor via a serial link. The Technique Processor responds to this, sending
the data back to the Control Panel Processor to update the VFD and/or turn on
the associated LED. The Technique Processor also communicates over a digital
bus to the Analog Interface PCB. The Tecnnique Processor PCB also
communicates with the Workstation via RS232 serial communications.
The information given in this section is most easily understood while refering to
the following schematics. Use the correct interconnect diagrams and circuit
board schematics for your system as indicated by the S/N.
