Installing the SunData s/w in your PC

In this section you will be told about the SunData s/w, and what you need to do to get it running on your PC. You will then use it to establish that your PC can communicate with the SunScan probe.

The SunData s/w Diskette

What the s/w does

The s/w is provided as three groups of programs in separate directories on the diskette. If you find a README file in the root directory of the diskette, please read it. It may contain late release information not included in this manual.

SunData PC s/w (in the \PC directory)

You must install this in a PC for transferring data files from the Workabout to the PC. You can also install it in a (portable) PC to enable the PC to act as a data collection terminal instead of the Workabout.

SunData Psion s/w (in the \PSION directory)

This is a backup copy of the s/w that is pre-installed in the Workabout. You will not use this except in the unlikely event of program loss from the Workabout.

Psion communications s/w (in the \COMMS directory)

These are DOS programs provided by Psion which enable you to transfer files between the PC and Workabout. Full documentation is provided on disk and in the appendices. They will not be further described in this section.

These programs are essential if you need to restore s/w lost from the Workabout, (unless you have purchased the optional PsiWin Windows s/w), and of course they give you alternative methods of transferring data files from the Workabout to your PC, if you don't want to use SunData's own data file transfer method.

Installing the s/w

Your PC requirements

Your PC needs: DOS 3.3 or higher; a 3.5 inch 1.44 MB diskette drive, and an available serial port with 9 pin D-connector

You may need to refer to your PC manual to carry out the following tasks: copy a diskette, create subdirectories, copy files, and run programs from the DOS prompt.

You should make a copy of the SunData s/w diskette immediately for routine use. Store the original diskette securely, and set the write-protect slider on the diskettes.

Copy all the diskette files to your hard disk drive (HDD). You are recommended to use the same diskette directory names and to put them all in a parent directory, for example: \SUNSCAN. At the same time, you should create another directory for storing SunScan data files, e.g. \SUNSCAN\SSDATA. You may choose alternative names for any of these directories if you wish.

♦Insert the SunData diskette in your PC's diskette drive.

♦Create the required directories on your PC's HDD.

♦Copy the files from the diskette to the HDD.

♦Remove the SunData diskette from the disk drive.

No problems should be experienced if you wish to de-install the SunData programs later. Simply delete all the directories and files that you copied on to your hard disk.
