*12W of power is dedicated to the USB-A and USB Type-C hub ports when a USB charger is connected to the USB-C charging port. The USB-A dedicated charging port supports 5V 1.5A (7.5W). When maxing out one port’s power, the other ports’ power is reduced. All ports will not be able to provide full power simultaneously, meaning external power may be required for some connected peripherals.

Installation

Notes:

Supports the connection of three monitors at the same time through DisplayPort MST Mode.*
To ensure proper function of the five USB (4 USB-A and 1 USB-C) hub ports, make sure to plug in the included external power supply or the host device’s PD charging power supply to the unit.
When the included 72W power adapter is connected to the DC port, it supplies power to charge the host PC first (up to 60W) with the rest of the power being supplied to the dock.
When the PD charging power adapter is connected, 15W of total power will be reserved first to guarantee the functioning of the product. The rest of the power will be used to charge the host PC (the power that the host PC can get depends on the result of PD protocol negotiation).
When the DC port is connected prior to the Type-C PD Charging port, the docking and host PC are powered from the DC port, with the Type-C port as an alternative power source.
When the Type-C PD Charging port is connected (with a PD power adapter) prior to the DC port, the docking and host PC are powered from the Type-C port with the DC port as an alternative power source.
If the active power source (power source that is supplying power) is unplugged, the alternative power port will be switched on automatically to be the active power source. In this case, the connected devices will get disconnected for a few seconds and then reconnect automatically.
See Optional Accessories section for suggested cables.
When the unit is connected to the USB-C port on your computer and to a network via Cat5e/6 cabling, a network connection will be automatically established. If no connection is made, you can manually establish one by going to your computer’s network settings page. For example, on a Mac, you would navigate to the Network section found in System Preferences, click the “Assist Me” button to get to the Network Setup Assistant, then follow the prompts to establish a connection.

See Multi-Monitor Requirements section for details.
1. Connect the included power supply between the unit and a power source and/or the included USB Type-C cable between the unit and a PD charging adapter (not included).
  Note: The USB hub ports may go into overcurrent protection if high- powered USB peripherals are attached without the external power adapter being connected. The USB Type-C PD Charging port can also be used for data transfer.
2. Connect a USB Type-C enabled laptop or computer to the unit’s USB Type-C host port using a USB Type-C cable.
3. Connect a 3.5 mm Mini Stereo cable to the back of the unit to connect a speaker.
4. Connect up to four USB devices to the dock’s USB-A hub ports.
5. Connect the adapter’s RJ45 port to a network using a UTP cable.
6. Connect the dock’s VGA port to the VGA port on a monitor using a VGA cable.
  OR
7. Connect the dock’s HDMI port to the HDMI port on a monitor using a HDMI cable.
  OR
8. Connect the dock’s DisplayPort port to the DisplayPort port on a monitor using a DisplayPort cable.
9. Connect a 3.5 mm Mini Stereo cable to the front of the unit to connect a microphone or headphones.

Multi Monitor Requirements

The U442-DOCK4-S and U442-DOCK4-INT support the connection of three monitors at the same time through DisplayPort Multi-Stream Transport (MST) mode. Below are limitations that must be taken into account when connecting multiple monitors at the same time.
Note: If a triple monitor installation is desired, it is important to connect all three display outputs before connecting the power supply and powering the unit. If only two of the three connected displays are illuminating, the power must be cycled by removing power from the unit with the three displays still connected and re-connecting the power.

Does the Source Computer Support DisplayPort MST Mode?
When connecting to a USB-C source that supports DisplayPort MST mode, the EDID information of the two or three connected monitors
will be read by the computer and appear as separate displays that can be shown in mirror mode or extended mode. When connected in MST mode, the computer graphics card will have a total bandwidth of 10.8 Gbps for all video ports.
When connecting to a USB-C source that does not support DisplayPort MST mode, Single-Stream Transport (SST) mode is used instead. In SST mode, only the EDID of the first connected monitor is read by the computer, forcing the connected monitors to display in mirror mode. The default resolution of the first monitor will then be sent to the second monitor and/or third monitor, with all monitors displaying the same resolution. If the second monitor is not capable of supporting the same resolution as the first, no video will display on that monitor. Before connecting the second monitor, the first monitor’s resolution must be changed to the second monitor’s resolution in order for video to be displayed.
Note: The following table depicts the maximum resolution achieved on each video port, based on the connected monitors. Mac does not support DisplayPort MST; therefore, multiple monitor setups are not guaranteed.

Multi Monitor Requirements

*| 1920 x 1080 @ 60 Hz| 1920 x 1080 @ 60 Hz

Windows Source (Triple display)
VGA| HDMI| DisplayPort

Supports 3 displays to work simultaneously under MST mode, 3 videos share max 10.8 Gbps bandwidth (e.g., dual 1080p/60 Hz,

or 1 x 1080p @ 60 Hz + dual 720p @ 60 Hz).

2) Some host PCs only support output of 3 video streams/monitors.

To ensure the output of the 3 displays, turn off the screen of the host PC.
