utility on each of the connected computer before you
can use the Auto Switch function.
The USB Autoswitch is a bus-powered device in that it does not
have to rely on power coming from other sources than it’s PC ports.
However, some application of the USB device (such as a USB hard
disk storage device that relies solely on power feed from USB port)
can demand large power feed from its USB port. In this case, user
will need to plug in the external power adapter for more sufficient
power output.
Auto switch utility configuration
Before you can use the Auto mode to manage the USB job requests
automatically, one needs to install and configure the Autoswitch utility for
optimization.
Follow the below steps to configure your Autoswtich utility …
Step 1. Double-click the AutoSwitch utility icon within the system
tray to bring up the Configuration box.
Step 2. Configure the Idle Time: the Idle time is the timeout (in
sec) that the Autoswitch will wait after a task is finished before
the switch becomes available again. After you have enter the
value, click Apply to make it validated.
Step 3. Select Printer: If you connect a Printer to the USB
device port for sharing, then you have to specify which printer
needs to be managed by the Autoswitch utility when a printing
request is directed to it.
Click Select to bring up the printer listing and then select the
printer you want. And then click OK.
Now the Autoswitch utility has been configured, and you can use
it on the computer to manage the USB job request automatically.
Step 4. Repeat Step 1 ~ 3 to configure the Autoswitch utlity on
each of the connected computers.
Select Auto Mode or Manual Mode?
Auto Mode
By default, the Autoswitch will be set in Automode, as indicated
by the lit AUTO LED (amber color) on the front panel. Automode
means users of each connected computers don’t have to worry
about whether the shared USB device is available while they are
sending out the job requests. They can just “Send-and-Forget” it
and the job will be automatically dispatched to the USB device—
All these tasks are managed and controlled by the Auto Switch
utility.
Thus, we suggest you to install the utility software on each of the
connected computers. And let the software utility take care of it
for you!!
Manual Mode
However, manual mode is still an option if you need to intervene
and designate a certain computer to take the USB device. If that
is the case, you can force the Auto Switch into Manual mode just
by pressing the Switch button on the front-panel.
Auto/Manual Mode Switch Button
The Switch button is located on the front-panel, and which allows
the switch to rotate between the following states:
Automode (default) ÆManual Mode (Port 1 ÆPort 2 ÆPort 3 Æ
Port 4) ÆAutomode
For instance, while you are in Auto Mode, and you press the
Switch button for once, it will enter Manual mode/Port 1 (that is,
port 1 has the access) and one further press will take the switch
to manual mode/port 2 (that is, port 2 has the access) and so on,
then right back to Auto Mode again.
While in manual mode, the active port LED (Green) will first lit
solid, which indicates that it is dedicated ONLY for the access of
that port, and it cannot be switch to other port manually. One has
to wait for the timeout (about 16 seconds) to expire before the
LED becomes flashing, which indicates that there’s no data
transmission (hence no job going on for that port) and it can be
switch to the next port.
Thus, users can force the Auto Switch to go manual mode in
favor of a certain connected computer just to get the more urgent
jobs done nice and quickly.
In most cases, Auto mode will suffice. And manual mode will
serve only in special cases when users need to allocate the USB
resources to a certain computer.
LED Status
AUTO LED (Amber)
ON – Automode
OFF – Manual Mode
PC Port LEDs – PC1, PC2, PC3, PC4 (Green)
ON – Not available for switching to next port (either data
transmission going on or still waiting for timeout)
Flashing – Available for switching to next port
Now you can use your USB Auto Switch to manage your
USB job request. Enjoy it.
