To use them I have to get a laptop that has XP or Win7 and some way to connect a parallel port connection for the modified one.
We have a similar problem at work connecting from laptops to old computer equipment on the trains and the serial port makes all the difference.
Dell laptops had a serial port fitted longer than most laptop manufacturers: -
www.valucomputers.co.uk/acatalog/serial-port-laptops.htmlI have compiled a guide to using older hardware/software: -
Using older hardware – not a 100% guide.
• Avoid Windows Vista like the plague – compatibility/memory issues.
• Try Windows 7 or 8 before considering Windows XP
• USB to Serial adaptors can be fiddly to set up, go for one with a driver disc or check on the internet for suitable drivers BEFORE you purchase the adaptor.
• If Windows XP is your only option then consider a laptop/Desktop PC with a serial port as this is likely to work better than a USB to serial adaptor. Again check for drivers.
• In a permanent Obsy setup a desktop may be a better option as serial port(s) can be added easily using an expansion card – check if it needs drivers or they are included before purchase.
• Some makes of laptop had serial ports on later models than other makes.
• Only install the minimum amount of software that you need to do the job, USB to serial adaptors & serial ports may clash with other software.
• Check for software in ‘Startup’ that may grab a USB port, stopping it from working with other applications.
• If hardware is very old the Baud rate (information transfer rate) may have to be reduced in the serial port settings, though this is rarely needed in practice.
• I.P. Addresses are important with some File Transfer Programs, (FTP) information should be in the setup instructions, again this is rarely needed.
• Write down any changes to settings you make or save screen grabs with ‘Print Screen’ key on your keyboard, paste the picture into Word & save it that way. Then you can put the settings back if they don’t work.
I had a problem with the Mallincam software & the screen grabber software not working together, cured by using 2 PC's.
