I received my new V5 a couple of days ago.
I can’t update. I followed the instructions, but when I get to the part where I have to plug the serial connector to the Mac and run the JAVA command line, I get an error message saying something like: “Error opening port com3...”
After a while the calculator displays “TIMEOUT” or sometimes “HR or HS ERROR”, can’t remember which one.

I am doing XEQ CMOPEN before I hit ENTER on the terminal.

What am I doing wrong?

Neve,

There is no port "com3" on a Mac. What you need to do is to find the port where the serial cable is connected. Typically, you would have to search the /dev directory on OS X with the command "/dev/tty.usbserial*" (assuming you are connecting the serial cable via a USB port). You then replace com3 with the address of the serial port. For example, on my Mac, the command to start the JAVA program is:

java -jar clupdate-1.0.0.jar --update rom_files_171106.zip /dev/tty.usbserial-DO002NJS 4800

As you can see, "com3" is replaced by the location of the USB port where the serial cable is plugged in (via a serial to USB adapter), in this case, "/dev/tty.usbserial-DO002NJS". Hope this helps.
