Troubleshooting
Problem Possible solutions
The DA305 does not
work with the USB-A
port on the PC
The DA305 is only compatible with the USB-C port on the
PC, i.e. Thunderbolt port or USB-C (DisplayPort Alt Mode)
port.
Multiple displays are not
working
The DA305 supports only single display out. You can only
connect one display to the HDMI port, DisplayPort, or
USB-C port at a time.
Unable to read and write
to an external SSD/HDD
and optical (CD/DVD/
Blu-ray) drive when
connected to the DA305
• Some external SSD/HDD/ODD devices require higher
power that what the DA305 can supply.
• When DA305 connects to 7.5W USB-C port of your PC
and without power delivery pass-through charging, it is
recommended that you connect external SSD/HDD/ODD
to the PC directly.
• When DA305 connects to 15W Thunderbolt or USB-C
port of your PC and without power delivery pass-
through charging, it is recommended that you connect
only 1 external
SSD/HDD/ODD drive to DA305. Additional devices can
be connected to the PC directly.
• When DA305 connects to your PC with power delivery
charging pass-through (USB-C power adapter or
USB-C monitor with power delivery capability), it is
recommended that you connect only one external
SSD/HDD/ODD to DA305. Additional devices can be
connected to the PC directly.
Power Surge message
pops up when connecting
a peripheral to the DA305
• The peripheral connected to the DA305 needs more power.
• Disconnect other peripherals connected to the DA305.
• For peripherals that require higher power, it is
recommended to connect the peripheral to the PC directly.
MAC address pass-
through, Wake-On-
LAN and PXE boot not
working on DA305
The DA305 does not support MAC address pass-through,
Wake-On-LAN and PXE boot.
Resolution on monitor
is lower than 4K 60Hz
when connected to the
HDMI, DP port of DA305
• Check and ensure the monitor is capable to support 4K
60Hz
• 4K resolution at 60 Hz is supported on PCs that
supports DisplayPort 1.3 or above (HBR3) with a monitor
that is capable of 4K resolution at 60 Hz. On PCs that
support below DisplayPort 1.3, the maximum resolution
supported is 4K at 30 Hz
PXE boot in UEFI/
Legacy mode is not
working
DA305 does not support PXE boot.

Troubleshooting
Problem Possible solutions
Video / Audio
performance issues
• Check and update PC BIOS, graphic driver and audio
driver for the latest version.
• Check and update PC Thunderbolt rmware and driver to
the latest version.
No video on the monitor

• Check the video cables and ensure they are connected
correctly.
• Disconnect the peripheral from the DA305, wait for 10
seconds, then connect the peripheral.
Video on the attached
monitor is distorted or
pixelated
• Check the video cables and ensure they are connected
correctly.
• Check and update the video resolution under Control Panel
> All Control Panel Items > Display > Screen Resolution.

The DA305 is not
charging your PC or
is charging your PC
slowly. You may also see
a yellow triangle with
an exclamation mark on
the battery status icon.
• The DA305 supports max 90W power delivery pass-
through.
• The DA305 reserves 15W, so your system gets 15W less
power from the power source. You may observe a slow
charging message/icon because of this.
• It is recommended to connect the power adapter to the
PC directly. Alternatively, you may choose to connect a
higher power rated USB-C power adapter to DA305.
