C. Upgrading the SunScan system

From time to time, new issues of the software programs in the SunScan system may be released and offered to existing customers. Brief notes follow for what is involved in installing them.

The SunData PC s/w

New versions of the PC program file SunData.exe will be provided on a floppy disk. Rename the existing file on your PC's hard disk, then copy the new file across to the same directory as was previously used.

The Workabout SunData s/w

New versions of the SunData.app file (and any other files needed in the Psion), must be copied across to the Workabout and the application installed. To do this, you will need to use the SLINK or RCOM file transfer utilities, or the PsiWin program if you have it.

Once you have copied across the new program file, you will need to install the SunData application as described in the section More Psion and file handling notes.

Revision History

Full release versions of hardware, software and documentation are v1.05 or later (December 1996).

Pre-Release units were issued before this time. A free of charge upgrade has been offered to all pre-release customers. If you are unsure about the status of your equipment, please refer to the earlier Technical Support section of this manual for how to locate version and serial numbers, then contact your agent or Delta-T.
