WiFi Interface

Through its WiFi interface, the MiniPlex-2Wi can communicate with a wireless device such as an

iPad, iPhone, an Android based smartphone or tablet, a PC or a Mac. The multiplexer creates a

wireless Access Point 820.11b+g interface with the following parameters:

SSID (name): MiniPlex-2Wi:xx:xx

IP address: 10.0.0.1

Port: 10110

Protocol: TCP

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.

A wireless device that connects to the MiniPlex-2Wi will get an IP address from the built-in DHCP

server. It is not necessary to set a fixed IP address in your device.

Configure your navigation software to connect to IP address 10.0.0.1 and port 10110 using the TCP

protocol.

The MiniPlex-2Wi supports only one connection WiFi connection at a time. The WiFi interface and

the USB port operate simultaneously and with the same priority. This allows an on-board fixed

computer to be connected simultaneously with a wireless device.

The WiFi interface cannot be used to update the firmware of the MiniPlex-2Wi or to configure the

WiFi interface using $PSMDWI commands (see the Technical Reference, Proprietary NMEA

Commands). All this has to be done using the USB interface.

Power Supply

The multiplexer must be powered from an externally supplied DC voltage from 8 to 35V. The power

supply connection is protected against reversed polarity.

Indicators

The multiplexer has three LEDs. The green LED indicates the reception of valid NMEA data on the

listener ports or from the network. It only blinks on valid NMEA sentences that start with a ‘$’ or ‘!’

and end with a CR and LF character, thus indicating a proper connection and polarity of the

connected instrument. In case of a reverse polarity of a connected talker, the green LED will not

blink. The green LED also blinks every two seconds to indicate that power is present and it is

operational. This blink is slightly dimmer than a blink on data reception.

The red LED indicates a queue overflow, in case more data is received than can be transmitted.

See section ‘Data Throughput’ for options to resolve this situation.

During a firmware update, the red LED will be lit continuously when the update is in progress while

the green LED blinks on the reception of firmware data from the computer. This will give a visual

indication of the update process.

The yellow led indicates the status of the WiFi connection: and has three possible states:

Off: The MiniPlex is configured to connect to a WiFi Access Point but the connection failed.

On: The WiFi Access Point is active and ready for use.

Blinking: An application has connected using TCP.
