HARDWARE INSTALLATION (CONNECTION) OF THE DOCKING STATION TO THE MAC
- Turn ON the Mac.
- Connect the power adapter to the docking station and connect it to the AC 110V / 230V grid.
- Connect the Thunderbolt™ cable to the Thunderbolt™ port on the back panel of the docking station.
- Connect the Thunderbolt™ cable to a free Thunderbolt™ port of your Mac.
- The installation of the docking station and the ports will start automatically.
- When the installation is completed we recommend turning the Mac OFF and ON.
Installation of the drivers in Mac OS X is automatic.
USING THE DOCKING STATION IN MAC OS X
A: After connecting the monitor / monitors (with the Thunderbolt™ or HDMI or Display Port input) the screen on your Mac will glimmer, which is a standard condition, and after stabilization it is possible to perform standard setting of the monitor here: System Preferences-Displays.

Click on Arrangement and in the default mode (Expanded desktop) click on the new monitor and drag it as necessary vis-à-vis the Mac monitor. If you select Mirror displays the mode will change to Mirror (the resolution of the monitors will be automatically adjusted according to their parameters and the highest possible resolution will be set on both monitors). By cancelling the Mirror displays option you will return to the Expanded desktop mode.
Expanded desktop mode: The arrow indicates the possible position of the connected monitor vis-à-vis the Mac monitor.

In the Expanded desktop mode you can choose the Main monitor by dragging the Menu Bar.

Mirror mode: This mode can only be used if supported by the Mac.

Click on Gather Windows: using this option you can choose the settings of the corresponding monitor - Scaled (offers available resolutions), Rotation (Standard, 90^ , 180^ and 270^ ) and Refresh rate (if offered).



Notes for using the docking station with monitors:
- Working on the connected monitor when the Mac monitor is closed is possible with the power supply from the grid (there are some limitations when using a HDMI monitor on older versions of Mac). When the power supply is from the battery, the use of a HDMI monitor is limited by the Mac (in some situations in case of problems with displaying it is possible to use the method described in the following paragraph).
- Most problems with renewing the screen on the connected monitor after hibernation of the Mac, after usingscreensaver, after restarting the Mac, after turning the Mac OFF / ON can be solved by disconnecting the Thunderbolt™ cable of the docking station from the Thunderbolt™ port on the Mac and reconnecting it after approximately 10s. Please wait for completion of connection of all peripherals.
B: After connecting other devices to the docking station (e.g., Ethernet cable to the GLAN port, Thunderbolt™ external HDD, USB external HDD, USB keyboard, USB mouse) these devices are used in a standard way.
Most problems with the docking station and the connected peripherals can be solved by disconnecting the Thunderbolt™ cable of the docking station from the Thunderbolt™ port on the Mac and reconnecting it after approximately 10s.
CHARGING
The docking station supports charging of the connected USB mobile devices such as smart phones, e-book readers, multimedia players, navigation devices, and tablets. Simply connect the device that you want to charge using the original cable to the USB port of the docking station.
