Re: Mark IV PRC - 100 Communication Issue

2016-02-03 by sioniee@...

Hi David,


To download the Virtual PRC Java app to your PC, you need to use your web browser on a PC connected to the same network as the piano.


To do this, you would need to know the IP address of your piano and place it in the web browser address bar as part of the address string as example below:


http://xxx.xxx.xxx.xxx/prc/prc100.jar


Where xxx.xxx.xxx.xxx is your piano IP address. Mine is 192.168.1.90 so the address to download the virtual PRC looks like the following:


http://192.168.1.90/prc/prc100.jar


If this has worked, you will be asked to save or run the file. Choose save and save the file in the C drive as c:\prc100.jar


Make sure you know the version of java you have installed on your PC as you will need it to create the shortcut in the next part.


On your Windows desktop, right click and choose new > shortcut. In the box, type the following command:


"C:\Program Files (x86)\Java\jre1.8.0_65\bin\javaw.exe" -cp c:\prc100.jar gui.prc100 -h=192.168.1.90 -p=3191 webremote -w=31910


This is where it gets a bit tricky. The part in quotes will vary depending on the actual file path to your javaw.exe file. The directory depends on the Java version installed.


c:\prc100.jar is the path for the location for the file you saved from your piano earlier.


-h=192.168.1.90 This must be changed for the correct IP address for your piano.


Save the new shortcut.


Get these variables right and you will have a working PRC 100 on your computer screen once you click on the new shortcut icon.

It should give you the same features as on your physical PRC100.

Good luck.

Sion

No, the virtual PRC is essentially a PRC simulator for your PC. When you load it, you will see an image of a PRC100 on your computer screen. The buttons and functions will work exactly the same as the real device.

I think the files are stored on the piano itself. You can download them to your PC over the network. It runs in Java which can be a problem if your PC has been upgraded to the latest version of Java because of the security issues.

There is a command line to run which will get round those issues however. I will take a look at the setup of mine and post some instructions tomorrow.

Thanks

Sion

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
