WiFi Interface
(MiniPlex-2Wi)
Through its WiFi interface, the MiniPlex-2Wi can communicate with wireless devices like an iPad, iPhone,
a PC or a Mac.
WiFi Access Point
The MiniPlex-2Wi provides a wireless access point through its 802.11b+g interface with the following
parameters:
SSID (name): MiniPlex-2Wi:xx:xx
IP address:
10.0.0.1
Port:
10110
Protocol:
TCP/IP
DHCP server enabled
No security or encryption
The xx:xx’s are the last two bytes of the MAC address of the multiplexer as printed on the serial number
sticker. This uniquely identifies a MiniPlex-2Wi from similar devices.
On an iPad for instance, the MiniPlex-2Wi will appear as shown in Figure 20.

Simply tap on the MiniPlex entry to connect to the MiniPlex. No further configuration is required.
The built-in DHCP server automatically assigns IP addresses to devices that connect wirelessly to the
MiniPlex-2Wi. It is not necessary to make any settings in the network configuration of your wireless
device. Up to 7 devices can be connected simultaneously.
The access point also provides routing, which means that all connected devices can also communicate
with each other using TCP or UDP.
The NMEA data from the multiplexer is available on the WiFi network as UDP Broadcast or TCP on port
10110. Every device on the network will receive this data and every device can also send data to the
network using UDP.
The MiniPlex-2Wi also supports TCP but this is limited to one connection only. As soon as one device
opens a TCP connection to the MiniPlex-2Wi, the UDP broadcasts will stop and no other device will receive
NMEA over UDP anymore until the TCP connection is closed again.
The specific advantages and disadvantages of TCP and UDP are explained in chapter “Protocols” on page
16.
