Figure 3.10 Motion controller input/output
The motion controllers receive commands, either from the hand controller or from the acquisition
PC. The hand controller is connected to the Linear controller's digital input port. Further inputs –
safety signals etc. – are connected to the Rotate controller's digital input port.
The communication from and to the acquisition PC takes place via one of the detector EDC
boards, which translates between the PC's IEEE 1394 FireWire interface and the motion
controller's CANbus interface.
The hardware of the two motion controllers is identical. The software for the two motion
controllers must also be identical. A DIP switch is used to set the controller's identity (Rotate or
Linear controller).

Electrical Inputs

In the motion controller I/O diagram (Figure 3.10), the following electrical inputs can be
identified:
•
CANbus (bi-directional) – for communication (control/status) with the EDC boards
•
HSSI interface (bi-directional) – for communication between the two controllers
