Controls

The control area of the MPX-Config screen allows you to configure the multiplexer. It is devided in

two parts: a small part on the left contains the Host Port settings, the Manual NMEA Sentence

Input, the overflow indicators and the Read

Configuration button. These items are available at all

time. The largest part on the right contains all settings that

control the operation of the multiplexer. These settings are

logically grouped on tabbed pages. When started for the

very first time, the NMEA Inputs/Outputs tab is shown. On

exit, MPX-Config stores the currently active tab and shows

this on the next startup.

Host Settings

Before being able to configure the multiplexer, select the

communication port to which the multiplexer is connected

in the Host Settings. These settings control the

communication settings of your computer or tablet, which

are called the Host. Nothing is changed in the multiplexer

here. Because there are several ways to connect a host to

the multiplexer, you will find a number of possible ‘ports’ in

the Port selector, ranging from available COM ports on your

computer to TCP and UDP.

Depending on the kind of selected port, the Host Settings

section changes its appearance. When you select a COM

port, the section shows a Speed selector to select the

communication speed of the COM port. When TCP or UDP is

selected, the section shows an entry field for an IP address.

In case of a virtual COM port (a COM port created by the USB driver of the MiniPlex), the COM port

is marked with ‘(vcp)’ and the Speed setting is irrelevant.

If you connect to the multiplexer using TCP, enter the IP

address of the multiplexer in the Host field as shown. The

IP address of the MiniPlex-2Wi is 10.0.0.1.

Once you have set the desired settings, click on the

Connect button to start the connection to the multiplexer.

When a virtual COM port has been selected, the Speed setting will change to Automatic and will

be disabled. MPX-Config will now retrieve the current settings from the multiplexer and enable the

tabbed configuration pages.

If a ‘Multiplexer does not respond’ – message appears, you may have selected the wrong COM

port. In case of a wrong IP address, an ‘Unable to connect’ –message appears.

If you exit MPX-Config, the port settings will be saved and reloaded on the next start-up of MPX-

Config.

When you select a different port while being connected, MPX-Config disconnects from the

multiplexer and you have to click on Connect again.

Manual NMEA input

MPX-Config allows manual entry of NMEA sentences for testing, configuration etc.

Type the desired NMEA sentence in the edit box and click on the Send button or press the enter

key. MPX-Config will keep a history of entered sentences/commands.

Preceding the NMEA sentence with a ‘$’ is optional, MPX-Config will add it if it is omitted. The input

is case sensitive, so whatever you type will be sent to the multiplexer literally. Since all NMEA

commands are uppercase, you have to enter them as uppercase.

Any sentence starting with ‘$PSMD’ will be recognized by the multiplexer as a configuration

command and will be processed as such. Any other sentence will be sent to the NMEA outputs.

Input Overflow

The overflow indicators show which input suffers from a queue overflow. See the section ‘Data

Throughput’ for ways to prevent overflow situations with different instruments.
