1Description and scope of delivery
Thank you for purchasing your MFD28/32 Gen2. With the CANchecked data display, you can display
live data from your vehicle while driving, log sensors and use many other functions that are
presented to you in this manual.
This guide explains how to operate and handle your Gen2 data display. In addition to the connection,
setup and navigation, this manual deals specifically with the individual setting and the connection
and operation of our "Display Setup Software" (DSS).
You received your data display in a vehicle-specific mount or in one of our universal mounts.
Depending on your order configuration, the contents of your original packaging may vary. Always
included are:
•the quickstartguide
•2 non reflective covers
•A SD card reader adapter
•CANchecked stickers
•One USB cable
•and either two Molex connectors (8 pin and 10 pin) and a choice of different pre-crimped
leads and two 1kohm resistors or a pre-terminated OBD cable
Your display itself has a capacitive touch screen, two Molex connectors on the back, a MicroUSB port
and a slot for a MicroSD card. The MicroSD card is always pre-assembled in your CANchecked data
display and described by us with data for your vehicle.
The sensors and page configurations are stored on the microSD card. For faster charging and display,
the display also has an internal flash memory. To remove the MicroSD card, after switching off the
display, the SD card must be pressed in slightly with a suitable object or fingernail to loosen the
latching nose. After pressing in, the MicroSD card springs out (please proceed carefully so that it
does not jump out uncontrollably).
Terms associated with the data display are shown in italics in this guide for better understanding.

2Connection of the plugs
To operate your MFD28/32 via the Can bus, only four wires are required:
•12 volts on-board voltage, ideally ignition plus -> Pin A5
•Ground -> Pin A1
•Can High (CanH) -> Pin B2
•Can Low (CanL) -> Pin B3
Alternatively, you can replace 12 volts on-board voltage and ground with a USB power supply. For
operation in the vehicle, we expressly recommend a connection via 12-volt ignition plus and
ground. The wires of CanH and CanL are always designed as twisted pairs to minimize interference
signals.
Figure 1: MFD28/32 Pinout
Of course, CanH and CanL are not necessarily necessary for operation. Via the four analog inputs
(AINs –analog inputs) you can also feed the 0-5 volt voltages of analog sensors into the display and
have them converted by the display and displayed on it.
By default, our AINs are preconfigured for different sensors:
•AIN1: Oil Temperature (OilT) -> Pin A8
•AIN2: Abgastemperatur (EGT) -> Pin A7
•AIN3: Oil pressure (OilP) -> Pin A4
•AIN4: Ladedruck (MAP) -> Pin A3
The power supply for operating the analog sensors can also be realized directly via the display. Pin A2
and pin B8 are 5V during operation, and the sensor ground can be obtained from SensorGround A6.
The maximum current of 0.5 amperes should not be exceeded.

Furthermore, the MFD28/32 Gen2 has a frequency input. With this you can separately feed wheel,
engine or turbocharger speed (5V square wave signal) or the ethanol content of your fuel into the
display. Pin B5 or B10 can be used for these applications. More information can be found 9.5.6 9.5.6.
Some settings can be implemented directly via the display. For detailed configuration or the creation
of your own pages, the use of DSS (Display Setup Software) is necessary. The download is free of
charge at https://www.canchecked.de/downloads-category/dss-display-setup-software/. The
display is connected via the supplied USB cable. We recommend leaving it connected to the display
and hiding the USB plug in an easily accessible place. In this way, easy access to your data display is
possible at any time without disassembly. The glove compartment, the side covers of the dashboard,
or the trim of the central consoles have established themselves here.
In the meantime, we have produced illustrated installation instructions for numerous vehicles. These
can be found on our website under www.canchecked.de/help/einbauanleitungen/. If you have a
CANchecked data display with a plug-and-play OBD data cable, it is recommended to connect it
briefly with the data display to the OBD socket before final installation behind the fairing in order to
check the correct connection and familiarize yourself with the user interface.

3Navigation on the display
You can operate your display like any standard smartphone with touch and swipe gestures.
Figure 2: Gestures to operate the data display
To switch sides, simply swipe left (one side forward) or right (one side back) across the display.
During the page change, you will be shown in yellow in a cutscene which page you are on. If you
switch to a blank page, the display in yellow font on a black background Page is empty! indicate.
Figure 3Appearance of a blank page
When delivered, most vehicles come with six pages pre-installed on your data display. In total, you
can set up up to ten pages on your display as you like or use our predefined pages with the help of
the DSS and get inspired, more about this in chapter 9.3.1

If you swipe down from top to bottom on your display (red arrow) you will be taken to the setup and
DTC (not available on all vehicles and protocols, more on this in chapter 6.2).
In the setup you can make all settings relevant for the operation of the display. The menu navigation
in the setup is described in chapter5
Figure 4: Setup and Quick Access Bar
If you swipe your finger from bottom to top (purple arrow) you open the quick access bar. These can
be accessed from any of the ten pages. Here you will find the button for logging, the slider for the
brightness of the display and a configurable custom button.

4Logging
To start and stop the log, press the button in the lower left corner after swiping up. Depending on
the active protocol (see chapter 6.26.2(without protocol) all sensors available in the TRI/TRX file are
logged. The logs are numerically incremented, and the button appears in green when the log is
active. If you press the green button again, the log will end. The display counts the logs up to 255
and then starts again at 0. This number is not customizable. On the SD card in the folder logs you will
find the log files after successful logging. Alternatively, you can use the Log Viewer in the DSS to
access your logs or delete them from the SD card. The logs are recorded every 62 ms (~16 Hz) and
should not exceed one hour due to the overview. You can read more about this in chapter 9.4
