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 > Communications > USB DRD Setup.

Auto

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

Host

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

Device

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