Hi,

I'm currently in the initial stages of putting forward a proposal to our science department to move to Linux (using LTSP to use lower spec client machines). However the only stumbling block I have is with the data logging software they use, Insight v3.

Are there any decent datalogging packages out there (there's bound to be) that anybody is using. I think the equipment they are using is from Phillip Harris and plugs in through a standard serial port.

Why not just use any existing older machines with Windows 95 for the data-logging locally and provide the rest via network thin client? If you get machines from for example free computers for education or use older machines in school, many will have Windows 95 so there is no additional cost. If they have and are familiar with insight they can then carry on using it but for WP, Drawing diagrams, Internet access etc use the thin clients. This gives you compatibility with legacy Windows and a development platform for the future that will be sustainable and inexpensive.

Also when we're using LTSP will the local machine COM ports still be accessible even though the software is running elsewhere? (Forgive my ignorance if this is a stupid question!)

Won't matter if you do as above. You can also provide a disc restore system from the server if anyone happens to mess up Windows 95 (well any more than it started of with ;-) ) Regards, -- IanL

If that's the one in Gateshead, I used to do Judo there back in the 70s. Coming up to Edmund Campion on Monday to discuss Linux thin clients for their EAZ.

By the way these units (Philip Harris DL128plus at least) output their data as plain text (this one can do so in several selectable formats) You can very easily communicate with them using a terminal app if your not keen on paying for the (windows) software at £150 (I believe)! Check the manual for default/changing the serial port settings - Xon/Xoff 9600,N,8,1 is a good starting point. If your not too keen on copy/pasting/editing data for frequent use, then it's also quite easy to capture the data into your own app, manipulate it and save it as a text file that can be imported directly into a spreadsheet for graphing purposes without further editing, making it child/teacher friendly. (the header, which you don't want to display, describes the following data layout, units etc.) The unit appears to scale it's data and so even very lengthy logging of all four channels will fit into a 32K buffer - I've not had any reports of overflow.
