InvoTek BlueHub User manual

BlueHub User Manual
Thank you for purchasing BlueHub! BlueHub is a Bluetooth hub which,
when paired with InvoTek’s MultiAccess Android app, enables the user
to control up to four personal electronic devices via one input device.
The Android input device runs the MultiAccess Android app. The app
provides an on-screen keyboard and cursor control and enables the
user to select which connected device they wish to control. When the
user makes a keyboard selection or cursor movement in MultiAccess,
the command is sent via Bluetooth to the selected device through
BlueHub. To the connected devices, BlueHub
looks like a normal Bluetooth keyboard and/or
mouse.

Input Switches
There are two switch jacks and buttons labeled SW1 and SW2.
BlueHub can use these switch inputs to perform scanning within the
MultiAccess app. MultiAccess provides sophisticated settings to
improve switch access for a user. BlueHub accepts any 3.5mm mono
switch output, such as a push-button switch or the output of a Sip-and-
Puff switch. The small buttons beside each switch jack are there for
convenience to test the functionality of switches during setup –
pressing a button is identical to activating its associated switch.

Charging Port
The Micro-B USB jack labeled “CHG” is used to charge the device.
When the provided USB cable is connected and powered, the device
will charge. On the front of BlueHub is a battery symbol with four LEDs
that display the current battery status. When the device is charging, a
battery LED corresponding to the charge level will
blink.
Unpair Button
This button is used to disconnect BlueHub from all
Bluetooth devices. This includes forgetting all the
devices which BlueHub attempts to reconnect to
on power up. To do so, hold down the Unpair
button for three seconds until a long beep is
heard.
On/Off Switch
The switch labeled “ON” is the on/off switch. To
turn the device on, slide the switch upward
towards the DIP switches. To turn the device off,
slide the switch downward towards the charging
jack. A green LED above the switch also indicates
when the device is turned on.

paired via Bluetooth to the MultiAccess app.
Battery Symbol

Pairing BlueHub to Devices 5
1) Turn on BlueHub.
2) On your phone/tablet/computer, navigate to the device’s
Bluetooth settings. Ensure your device’s Bluetooth is turned on.
3) In your device’s settings, scan for available Bluetooth devices.
Look for a device named “BlueHub”and select it.
If “BlueHub”fails to show up as an available device, turn
your device’s Bluetooth off then back on. Then re-scan
for available devices.
If that doesn’t work, turn BlueHub off then back on and
re-scan for available Bluetooth devices on your device.
4) If you are connecting to a device that will be controlled with
MultiAccess, the connecting process is complete. If you are
connecting to your input device running MultiAccess, finish the
connection process by opening MultiAccess. In the top right
corner, click the three dots for the menu. In the menu, click
“Connect to Hub”. At this point, the Connected LED on BlueHub
will turn green and within a few seconds any devices connected
to BlueHub will be listed in the device bar in MultiAccess (e.g,
Nexus 7 and ERIK-THINK in Figure 4).
Using BlueHub with MultiAccess 6
BlueHub works seamlessly with MultiAccess to enable you to control
multiple personal electronic devices using one input device. Start by
connecting the devices to be controlled by following the steps listed in
the Pairing BlueHub to Devices section. Then open MultiAccess on your
input device. The names of the devices you connected will be shown in
the device list. Figure 4 shows a screen shot of MultiAccess with two
connected devices: Nexus 7 and ERIK-THINK. Nexus 7 is selected as the
device to control, indicated by green highlighting. Any keyboard
selections will be sent to the Nexus 7. Figure 5 shows one of two cursor
control layouts in MultiAccess. The second layout is a trackpad area
that replaces the cursor movement arrows.
