JVC NZ800/900 series control issues

It has recently come to our attention that control systems have failed to communicate to the new line of JVC projectors - the reason for this is that they have enabled network password with a SHA256 encryption, as such most control drivers have not been updated to support this so we are needing to do this ourselves to get this to work.

On your JVC unit under the network settings please enable the Network Password option and fill in a password of your choosing, for this example we will use "Password123" 

Please then go to this conversion site - https://www.convertthisfile.com/conversions/hash-generator / https://tools.keycdn.com/sha256-online-generator once open put the password you have set on the JVC into the text field along with JVCKWPJ making the password now "1234567890JVCKWPJ" and hit "Generate"

With the list of passwords that populate copy the SHA256 password and enter this into the network key of your control system driver to gain connection 

To confirm connection works use a TCP client such as Hercules or packetsender to send the PJREQ command. NOTE only 1 connection is allowed at a time so please disable the driver in your control system or set to incorrect IP address before testing

Port 20554 
send PJREQ_(sha256 key) for example PJREQ_cc3054cf7c701a32a883bf45a7b19cbf7f62db778208b3c058e0c6dde886996f

If the response comes back as PJACK then this is now correct and the control system should be working.
