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
