PsiWin 2.3.3 for EPOC

If you want to connect your Psion to your PC then you will need the appropriate software plus an RS232 serial cable.

Windows VistaWindows Vista and PsiWin 2.3.3

Reports on the Psion Place forum and Psion Digest are that PsiWin 2.3.3 works fine with Windows Vista, one user reported that it may require some tweaking to get it to work properly.

(See Psion Place forum for more details -- also search the forum for PsiWin and Vista for the latest information).

About PsiWin 2.3.3

There are now a number of different applications which will allow you to do this, the most popular of which is EPOC Connect, which is badged by Psion as PsiWin; the latest version is PsiWin 2.3.3.

This page covers PsiWin 2.3.3, although a number of alternative applications are also commented on at the bottom of the page.

You can use PsiWin to connect the following PDAs

  • SIBO (Siena, Series 3, 3a, 3c, 3mx and WorkAbout) and
  • EPOC (Series 5, 5mx, 7, Revo, NetPad and Netbook)

to a PC running

  • Windows 95, 98, 98se, Me, 2000, NT4, XP or Vista.

Note: If you want to connect a Psion SIBO PDA to Windows 3.1x then you will need to use PsiWin 1.1.


Download PsiWin 2.3.3
from this site

You can now download PsiWin 2.3.3 from this website in various languages (English, German, Spanish, French, Italian, Dutch).

PsiWin is designed to run under Windows NT, 98, 2000 and XP.


Using PsiWin 2.3.3

PsiWin & Windows XP or Vista

PsiWin 2.3.3 will run under Windows XP and Vista (I recommend that you use PsiWin 2.3.3 with XP or Vista, as I know of people who have had problems even with PsiWin 2.3.2). Note that PsiWin is not network aware and offers no options for node installations. If you install it under the Administrator account then only the Administrator will be able to use PsiWin; if you install under a User Account then the user will be able to use PsiWin AND so will the Administrator. So think about how you will use PsiWin before you install it.


Check out the cables page for options on how to connect your Psion to your PC or laptop via serial cable, USB or InfraRed.

Connection problems?

If you are having real problems connecting to either PsiWin 1.1 or PsiWin 2.x you can test to see whether your Psion and Windows are even communicating at the most basic level by opening up the COMMS application on your Psion and HyperTerminal on your PC. More details can be found at Mike McConnell's excellent website under General Info, then click on Comms-Hyper.


EPOC R5 / Symbian OS v.5 files can be converted to PC format and vice versa.

Convertion is done via a drag-and-drop method, or via the Psion | Convert option in PsiWin. A dialog box will pop-up offering you various convertion formats and options.

Please note that converstion to and from Microsoft Access is limited as the built-in Data application is not a relational database. In my experience it is best to convert to a Comma Separated Values (.CSV) file.

Synchronisation & problems

Convertion to and from PIM applications, such as Microsoft Outlook and Lotus Organiser are best done via Synchronisation. Personally I do not know of any other way to do this.

If you are experiencing problems synchronising between your Psion and Microsoft Outlook it may be that your .pst file has errors in it -- this sometimes happens. Outlook installs with a tool to repair problems with your .pst file, called the Inbox Repair Tool (SCANPST.EXE) and is located in:

Outlook 2003:
C:\Program Files\Common Files\System\MSMAPI\1033

Older versions may have:
C:\Program Files\Common Files\System\MAPI\1033

Simply run the program, locate your .pst file and press the "Start" button.

Your .pst file is located (in Windows XP) in

C:\Documents and Settings\USERNAME\Local Settings\Application Data\Microsoft\Outlook

where "USERNAME" is your login name.

Installing Files

PsiWin 2.3.3 is excellent for installing Psion applications. Once PsiWin is installed simply double-click on a .SIS file on your PC and the PsiWin 'Install New Program' application will run, connecting to your Psion and installing the new application on your PDA.

For applications with no .SIS installation program you can use the drag-and-drop method to copy files to the appropriate folder on your Psion.


PsiWin 2.3.3 also makes backing-up files simple. I use both PsiWin 1.1 and PsiWin 2.3.3 to backup my 3mx, and PsiWin 2.3.3 to backup my 5mx.


Lotus Organizer 5.0 and 6.0
Plugin for PsiWin

PsiWin 2 plug-in for Lotus Organiser 5.0 and 6.0

There is a Lotus Organizer 5.0 and 6.0 Plug-in for PsiWin available for download (Zip, 1.34 MB) either on the Psion MyPsion website, or from this website.

The information about this plug-in on the Psion website suggests that it is compatible only with PsiWin 2.3.1, however, I have successfully synchronized my Psion 5mx Agenda and Contacts with Lotus Organiser 5.02 (SmartSuite 9.7) using PsiWin 2.3.3.

(You can find out which version of PsiWin you have installed by opening MyPsion from the Windows desktop and selecting Help | About PsiWin 2.3.)


Plug-in for Lotus Organiser 5.0 / 6.0 (Zip, 1.34 MB)

This is what the Psion website says about this plug-in:

"This is a plug-in synchronizer for PsiWin 2.3.1 which provides synchronization for Lotus Organizer 5.0/6.0 Calendar and Address Book. This plug-in is not supported for use with PsiWin 2.3.3. Lotus Organizer does not incorporate a native email application.

The plug-in enables: Revo, Series 3, 5, 5mx and Series 7 Agenda files (appointments, events, to-dos and anniversaries) to be synchronised with Lotus Organizer 5.0/6.0 Calendar.

Revo, Series 5mx and Series 7 Contacts file to be synchronised with a Lotus Organizer 5.0/6.0 Contacts list."


Upgrading from SIBO

The Upgrade command will check all the files on a Series 3 range Psion and copy and upgrade any files it can to your new Psion (Series 5 or later).

Before upgrading

  • Remove the password from protected files or Agenda memos on the Series 3 range Psion. Password-protected files or Agenda memos cannot be upgraded

  • Remove any Solid State Disks inserted in the Psion if you do not want the files on them to be upgraded. Files on SSDs are upgraded automatically

  • Switch off any automatic settings you have set in PsiWin. For example, if you’ve used PsiWin before this upgrade, and have chosen to automatically back up your Psion when you connect, you will need to turn this option off before running the upgrade program

  • Make sure that owner information is set on the Series 3 range Psion you are upgrading. PsiWin identifies individual Series 3 range Psions by the owner information in the System screen, so it is a good idea to ensure that each Psion you connect has different owner information

  • Set the link on each machine

  • To avoid problems with open files, close all files on both Psions

  • Connect the Series 3 range Psion you are upgrading, but keep your new Psion (Series 5 or later) to hand so that you can connect it at the correct stage during the upgrade

To start the upgrade

  1. Connect the Series 3 range Psion you want to upgrade to your PC and ensure that the link is turned on.

  2. Click the Start button on the Taskbar, point to Programs, point to PsiWin and then click on Upgrade from Series 3 or Siena. (If this is not available you will find the application in \Program Files\Psion\PsiWin\PSIUPGD.exe).

  3. If this is the first time you’ve connected the Series 3 range Psion to PsiWin 2.3.3 the New Psion dialog is displayed where you should enter a new machine name. If you’ve changed its owner details since you last connected, select the existing machine.

  4. When you are ready, click Yes to start the upgrade. The files are copied to the PC and upgraded to the correct file formats for a Series 5 or later model.

  5. Disconnect the Series 3 range Psion and remember to switch off the link to save battery power (Psion+L).

  6. Connect your new Psion (Series 5 or later), ensure the link is switched on (Ctrl+L) and then click OK to start copying the upgraded files

    All upgraded files are stored in a folder called 'S3 files' on the root (top level) of the Internal disk on the new Psion. From here, you can move the files to other folders as you require.
