Cerbo GX Manual

• The VE.Direct ports are isolated
• The VE.Can ports are not isolated.
• The USB ports are not isolated. Connecting a Wi-Fi Dongle or GPS Dongle will not create a problem as it is not connected to
another power supply. Even though there will be ground loop when you mount a separately-powered USB hub, during exten-
sive testing we have not found that it caused any issues.
• The Ethernet port is isolated, except for the shield: use unshielded UTP cables for the Ethernet network
Extending USB ports by use of a self-powered USB hub
Although the number of USB ports can be extended by using a hub, there is a limit to the amount of power that the onboard USB
port can provide. When extending the number of USB ports, we recommend you always use powered USB hubs. And to minimize
the chance of issues, be sure to use good-quality USB hubs. As Victron also offers a VE.Direct to USB adapter, you can use this
arrangement to increase the number of VE.Direct devices you can connect to your system, please see this document for the limit
of how many devices can be attached to various different GX devices.

No configuration is required. When the screen is connected, the device will automatically display the GX overview and menu con-
trols.

enable adaptive brightness.
The screen is controlled by a finger tip. You can swipe to scroll up and down through the menus, and tap to make selections.
