Power input — If using an Extron external 12 VDC power supply to power the HUB4,
connect it to the first two pins (labeled In) of this 4-pole, 3.5 mm direct insertion captive
screw port (see Connecting the External Power Supply
If desired, connect another Extron wall mounted device (for example, an
MLC 104 IP Plus AAP mounted with the HUB4) to the third and fourth pins (labeled
Out). Both devices can then be powered from the single connected power supply
(power loop out).
If the HUB4 is powered from the computer via the USB connection, this port is not
used.
NOTE: Ensure that your system power requirements do not exceed the capacity
of the Extron 12 VDC power supply. The current is limited to 100 mA per port
when the devices are powered via the USB port; 500 mA per port when they are
powered via the power supply.
Captive screw USB In port — Connect a USB A to unterminated USB B or USB
mini-B cable from the computer to this 5-pole 3.5 mm captive screw port (see
Connecting to the Captive Screw USB Port
Mini-B USB In port — Connect a USB A to USB mini-B cable from the computer to
this USB mini-B port.
NOTE: Only one host can be connected to the USB In ports at a time. If two hosts
are connected, the HUB4 defaults to the host attached to the USB mini-B port.
