3.2 Downloading Scanner Firmware
The scanner firmware is stored in Flash Memory on the SUC-Board.
Scanner firmware is available on:
http://www.contex.com/
Firmware is downloaded to the scanner through the IEEE 1394, USB, or SCSI interface,
please see readme.txt on the firmware disk for download instructions.
The download program:
CtxPrgm.exe
is started by double-clicking the self extracting firmware.exe file.
The download program reads the Download Control Switches, SW1 and SW2, on the SUC-
Board to check if the actual firmware and the SUC hardware are compatible.
The Download Control Switches are factory set, and the setting must not be changed.
If the scanner does not go into Boot Mode when the download program is started, the scanner
can be forced into Boot Mode by turning it OFF, setting SW7 on the SCSI ID-Switch to ON
(see page 61), and turn the scanner back ON. The scanner will now be in Boot Mode and new
firmware can be downloaded as described above. When the new firmware has been
successfully downloaded, turn the scanner OFF, set SW7 back to OFF, and turn the scanner
ON for normal operation.
3.2.1 Erase and Restore Parameter Blocks
The following two options may be found on the pull-down menu by right-clicking at the
CtxPrgm icon in the title bar of the CtxPrgm window:
• Erase Parameter Blocks
• Restore Parameter Blocks
‘Erase Parameter Blocks’ erases the Parameter Blocks (Stitching, Basic Calibration, Color
Calibration, etc.) in Flash Memory on the SUC-Board and save these in the file ‘backup.pmb’
located in the directory pointed to by the SET TEMP environment variable.
The file, backup.pmb, may be useful for diagnostic purposes.
‘Restore Parameter Blocks’ restores the Parameter Blocks from backup.pmb.
Note:
Always run Scanner Maintenance after Erase Parameter Blocks.
