What is the correct Java Runtime for a MW100 and how do I install it?

To do this, follow the below steps:

Step 2: Go to your preferred browser (Internet Explorer or Google Chrome) and enter the IP address of your unit into the address bar. Your browser should pull up a screen similar to that shown below:

Step 3: Navigate through and click System Setting --> System Information. Highlighted on the screen below is where the device should read Firmware version R3.10

Step 4: With your firmware verified, go to the link here and scroll down the page and click “Java 8 for MW, Update 31” (Note: This will require a sign-in to our Partner Portal)
