8-2. Frequently asked questions
Yes, if you use the Windows version of the MultiPresenter application.
Note that sound is only played when the image is displayed in full screen.
Access to the Internet is possible when the MultiPresenter Stick is con-
nected to an existing network that is connected to the Internet.
When connecting the MultiPresenter Stick to an existing network by
wireless LAN, use the Infrastructure mode.
The MultiPresenter Stick supports IEEE 802.11b/g/n 2.4GHz and WPA/
WPA2-PSK. Connection is possible if the wireless LAN network allows
connection with these standards.
Note that 5GHz, WPA/WPA2-EAP (environment requiring authentication)
and wireless LAN environments requiring an authentication procedure
using a web browser are not supported.
The MultiPresenter Stick uses the protocols and port numbers shown be-
low.

The transmitted data is encrypted in AES. For wireless communications,
security is ensured by WPA/WPA2-PSK.
The communication traffic volume when using the MultiPresenter Stick
is not fixed. It changes constantly according to the image resolution and
changes in the image.
Below are some approximate values with good signal conditions.
Network transmission quantity: [Min. 50kbps* 1 × no. transmitting devices
connected] to [Max. approx. 40Mbps* 2 ]
*1 With no changes on the screen of the transmitting device
*2 With Full HD resolution and the screen changing constantly (However, the approxi-
mate maximum value will be lower than this depending on the quality and frame
rate settings on the transmitting side as well as the device's performance and reso-
lution.)
There are no limits by design, but the number of devices to which images
can be transferred simultaneously depends on your usage environment.
NEC recommends using a maximum of 4 MultiPresenter Sticks. The num-
ber of MultiPresenter Sticks that can be used may be lower than this
when sending videos.
The MultiPresenter application only communicates with external servers
to check for the latest version. Otherwise data is never sent externally.
As long as the environmental temperature is within the specified operat-
ing temperature range (0 to 40°C/32 to 104°F), there is no problem oper-
ating the MultiPresenter Stick for 24 hours continuously.
To use it for longer, please turn the power off then restart the MultiPres-
enter Stick as necessary.
