Digitizer
  Select the digitizer you wish to control.

Probe Hardware
  If the selected digitizer is marked in the Configuration screen to require checking on selection (normally because the digitizer hardware is incomplete or under test) you will be prompted to use this function. Can be used at any time to check the digitizer hardware.

FPGA
  Select the Digitizer module to be accessed. If the digitizer is marked as not to be checked then all possible modules (total of 9) will appear in the menu. However if a check is required and/or following a hardware probe only those modules which have responded will be in the menu. 

Read PROM
  You can read the identification PROM in all modules (except for the core and segment main boards) which will return information such as the module serial number and mod state.
