R3220 CPU
Executes the main and boot SW of the unit.
Boot software
Loads the main software into the RAM and starts it.
Handles the initial unit software loading and boot mode
updates.
Main software
Controls and coordinates unit movements, exposure,
image acquisition and transfer.
The image data acquired during image capture are stored
in the internal memory of the unit. After image acquisition
the image data are transferred to the workstation using the
external 1000 Base - T Ethernet UDP/IP Ethernet.
It also handles multi connect and up to five clients (drivers,
S2Terminals or replicate PC touch screen displays) can be
connected to the unit via the external Ethernet.
It also offers firmware upgrade services for itself and
software upgrade for touch screen display. It also offers
core (FW) update service for R3300 IO1, R3400 IO2 and
R3210 Ceph as there is no direct connection from the
S2Terminal to these three boards.
R3300 IO1 software
Controls non-critical movements
R3400 IO2 software
Controls non-critical movements, IO, lights etc.
Communicates with CPU over a 100Base-T interface.
Touch screen display software
Holds the unit calibration data that is transfered to the
R3220 CPU during start up.
