Disabling DHCP
By default the MFD/chartplotter will act as the DHCP server for devices connected to the Ethernet (RayNet) network. If required the DHCP server can be switched off.
Automatic is the default setting for DHCP this allows the MFD/chartplotter to act as the DHCP server, unless another DHCP server is detected.
The DHCP setting should only need to be changed if you are experiencing conflicts caused by another DHCP server on the network.

From the Network settings menu: .
If DHCP is set to On the MFD/chartplotter will always assign IP addresses to connected devices regardless of whether another DHCP server is in use.
