Calibration source SW

• To do
• Use existing code for CDF HCAL calibration system
  (Borland C)
• Develop wrapper sockets/DIM (Delphi) for the
  beam-test in 2002
• After test with SCADA replace Borland socket
  component with DIM server
• Adaptation of the DIM server code to Borland C
• Conversion of Delphi DIM server to standard
  Borland Visual Component (VC) to use in Borland
  C Builder instead of Socket VC

Moving table (II)

• To do
• Replace existing remote keypad in the counting
  room with the keypad simulator (at the connector
  level) or modify the circuitry in the table
  control system.
• Develop a board controlled by the parallel port
  of the old PC (486, FSU,Win98). This PC works
  only for the table!!!
• Develop table control software with the socket
  connection or shared disk file (the simplest
  one).
• Develop socket DIM server (similar to the
  radioactive source, 90 of code to be reused).
• Develop PVSS panels.
