Earth Ground Connection

Grounding and wire routing help limit the effects of noise due to
electromagnetic interference (EMI). In order to reduce the environmental
background noise, we have added earth ground cooper on the Hub side
panel. User can run the ground connection from the Hub ground screw to the
grounding surface.

Power Adapter Connection

Plug the DC plug into the DC jack and plug the AC adaptor into an electrical
outlet. Please choice +12VDC Jack adapter or +12VDC 6-pin Mini-Din
adapters to the 6-pin Mini-Din power adapter. Pay attention that Do NOT use
both power adapters at the same time.

Note:

+12V DC Jack power adapter provides 2A tot al 24W and +12V 6-pin Mini-Din
power adapter provides 4A total 48W. Please confirm the total power current
of all serial device power consumption and select the suitable one.
