I think it allocated COM3 as the BIOS reserves COM1 and COM2 in “hardware” so it allocates the next available port but some machines allocate a high number like COM15 or higher.
#CASIO FX 880P BATTERY SERIAL#
I installed drivers in Windows 7 32-bit and device manager now sees both a Communications Port (COM1) and a USB Serial Port (COM3).

There should not be a question mark next to the serial port or USB ports listed there.
#CASIO FX 880P BATTERY UPDATE#
Windows should add a driver, mine tried to download one via Windows Update but failed so I downloaded FTDI drivers from here:Ĭheck Device Manager to see if the COM ports show up and are configured. When prompted, choose to connect it to the Windows guest (not the Apple host in my case). VMware and/or Windows Serial Port Configuration If you are on a Mac read the next section on configuring that using VMware. If you have a Windows PC you should be able to plug in the USB/Serial Adapter and the drivers should load automatically. I tested this running Windows 7 using VMware Fusion on a Mac but it also applies to any Windows PC running Windows 7 or newer. Ideally your Windows PC or Mac has a physical serial port but these days, that is very unlikely unless your machine is very old. If you are still interested in using the audio interface to save and load, stay tuned for a future blog post on that one. This calculator is designed to connect to the FA-6 cassette interface and that provides audio, serial and parallel ports to save and load programmable content to and from the calculator. This is the adapter I bought to connect the somewhat proprietary Casio connector RS-232/serial port:Īt the time of writing, these are listed for 65-70 Euro. However, most of us don’t have electrical expertise so that’s why I recommend… Option 3 Casio Serial / USB Adapter The connector of your calculator should have 30 holes, and you can adopt this for them using only the four noted above that need to be connected to the calculator like this: Write the colours of the cables connected to pins 2, 10, 11 and 19. Open the printer connector and search for the numeration of the pins, from 1 to 36. This should have 25 pins on the PC side and 36 pins on the printer side. Take a cable like that connecting your printer to the parallel port of your PC. Or another method…using the parallel cable and LPT on your computer: You can find the specs online to build your own serial cable like this guy did: Option 1 Cassette Interfaceīuy the FA-6 cassette interface that has a serial interface built in or use the cassette interface to capture the data as audio, not recommended.
#CASIO FX 880P BATTERY SOFTWARE#
These calculators are compatible with the Casio FA-6 Cassette Interface however given the rarity of that hardware, and the difficulty in using magnetic tape to record and playback the software on these, I though I’d explore various ways of transferring data to and from these calculators.
