Coprocessor Update Presentation
To update the coprocessor, you have to use OS Loader.
The CPU OS version needs to be at V 2.31 or later before the Ethernet port update.
Coprocessor Default IP Address
If the Ethernet port of the coprocessor is not configured in the Unity Pro application, it takes the IP address built from its MAC address:085.016.xxx.yyy where xxx and yyy are the last two values of the Ethernet port MAC address.
For example, if the MAC address is: 00.80.F4.01.12.20 in hexadecimal, the corresponding default IP address is: 085.016.018.032 in decimal.
Change the IP address of your PC to get it into the same subnetwork as the CPU.
The first three groups of digits have to be the same. For example, the CPU address is 85.16.133.13 and the PC address needs to be 85.16.133.xx.
Connect your PC to the CPU Ethernet coprocessor for the update.
