USB DRD Settings

The USB-C® dual-role-data (DRD) port on the chartplotter can function as either a USB host or a USB client (device), depending on the needs of the connected device. If your device has this port, it is labeled USB DRD.

Select Settings menu > Communications > USB DRD Setup.


The USB port automatically changes between host and client (device) mode. This is the default setting and should be appropriate for most connections.


This chartplotter manages a connected client device, such as a card reader or an external touch screen.


This chartplotter is managed by a connected host device. For example, the chartplotter can provide touch output to a host, such as a computer.
