2.4.2 OBDII Parameters
3Hardware
3.1 Connecting Power
Option 1: Using the Cigarette Lighter Power
This option is ideal if your cigarette lighter power is only ON when your ignition key is turned. In some
vehicles, your cigarette lighter power is always ON. Leaving your DM-100 OBDII unit always powered on
will drain your vehicle’s battery quickly. If this is the case for your vehicle, we recommend option 2.
Plug the 2.1mm power plug to the DM-100 control box where indicated ‘POWER.’ Plug the cigarette lighter
adapter connector into your cigarette lighter power plug in your vehicle.
Option 2: Hardwire your power connection
WARNING! CONNECTING THE DM-100 IN REVERSE POLARITY WILL
DAMAGE THE UNIT! CHECK CONNECTIONS BEFORE POWERING ON.
DAMAGE TO THE DM-100 WILL VOID YOUR WARRANTY.
The DM-100 accepts 12-18V DC for power. Connect the negative wire (black) to your vehicle’s ground.
This is usually the negative terminal of your automobile’s battery. Connect the positive wire (red) to your
vehicle’s ignition power. This power is only supplied when your key is turned passed a specific position and
is off when your key is removed. Your power connection must be capable of supplying at least 1 amp of
current. A 5 Amp fuse is recommended for safety. Plug the 2.1mm power plug to the DM-100 main control
box where indicated ‘POWER.’

The unit is working properly when the OLED screen turns on within 10 seconds. If your gauge does not
turn on, check your power connections and gauge connections.
3.2 iMFD Daisy Chain
The iMFD architecture allows you to connect up to 16 Display Modules and 16 Sensors in a daisy chain
format. Please keep in mind that the DM-100 Touch has 4 SMs built-in. The 4 built-in SMs can be
programmed up to 26 different combinations. See section (3.3).
Basic Setup:
The most basic setup is to have one DM-100 and one Sensor Module connected in the iMFD chain. Make
sure that the sensor module has the termination jumper INSTALLED. Use the 1ft serial cable provided to
make the connection. Again please note that your DM-100 Touch Already has 4 built-in SMs.
Multiple Sensor Setup:
If you have more sensor modules, simply connect them in between the DM-100 and the Sensor Module.
Make sure that any subsequent sensor modules added to the iMFD daisy chain MUST have the termination
jumper REMOVED. Use the 1ft serial cable provided to make the connections.
If you have more Display Modules, such as the DM-100, DM-200, DM-6, DM-5 AFR, DM-5 EGT, and etc.
Simply connect them to the left of the DM-100/200 in the above diagram.

3.3 Programmable SM-OBDII
Your DM-100 Touch includes two products in one. It combines a DM-100 and 4
programmable SM-OBDII modules into one product.
3.3.1 Termination
There are 2 options, Terminated and NOT Terminated. When the SM-OBD is terminated, it resembles the
following diagram
When the SM-OBD is NOT Terminated it resembles the following diagram.

12
3.3.2 Data Polling
Data Polling means that the SM-OBD ‘gets’ an updated value from the vehicle’s ECU (Engine Control Unit).
You can choose to turn ON or OFF Data Polling for Sensors 1,2,3,4. The more sensors you have set to
ON, the slower the refresh rate will be. It is recommended that you turn on data polling only on
sensors you wish to monitor, for maximum performance. By default, your unit comes preset with sensor
1,2,3,4 data polling ON.
For example, if you have your SM-OBDII set to:
Sensor1 = RPM
Sensor2 = Throttle Position
Sensor3 = Vehicle Speed
Sensor4 = Timing
And
Sensor1 Data Polling = ON
Sensor2 Data Polling = ON
Sensor3 Data Polling = ON
Sensor4 Data Polling = ON
RPM, Throttle Position, Vehicle Speed and Timing will all be monitored. However, the refresh rate of each
sensor is divided into 4. If you only wish to monitor RPM and nothing else, by setting
Sensor1 Data Polling = ON
Sensor2 Data Polling = OFF
Sensor3 Data Polling = OFF
Sensor4 Data Polling = OFF
Will lead to higher performance for sensor 1.
3.3.3 Programming Sensors Modules
Each sensor module can be programmed into any of the available OBDII sensors. Lists of the sensors are
below and can be programmed in the following setup menu. Keep in mind that your vehicle may not
support all the sensors listed below.
1) ABS THROTTLE (Absolute Throttle Position)

For standard users:
Please visit our online custom gauge database located here
http://plxdevices.com/customgauges/
You will need to install the USB device drivers and the DM-100/200 Utility before you can upload your
custom gauge. The files are located here
http://plxdevices.com/product_info.php?id=MULTDM100TOUCH
For advanced users:
This option is not recommended unless you have experience with graphic design.
Steps to creating and uploading your own custom gauge:
1. Set the custom gauge to your desired sensor from the setup menu.
2. Determine the measurement range for 0th frame through the 99th frame
3. Design your gauge
4. Upload your design to the DM-100
The DM-100 gives you the capability of designing your own gauge from the PC and uploading it to the DM-
100. You can do this in Photoshop or any other image processing software you have. You will need 100
images or “frames” of (160 x 128 pixels) in JPG, BMP, TIFF or GIF format. Each
image corresponds to a specific measured value to your custom gauge parameter. For example, if your
custom gauge is set to WAT (water temperature from the SM-FluidTemp) with the units set to “Cel”
(Celsius). Toggle to the corresponding analog gauge to determine your minimum and maximum range.
Notice that on the bottom left of the above analog gauge reads 0 and the bottom right reads 16 (160 Deg
because of the x10). This tells you the minimum and maximum range of your custom gauge. Custom
gauges simply displays the corresponding “frame” or image which is associated to the measured value in
the analog gauge.
0th frame = 0 Deg C
1st frame = 1.6 Deg C
2nd frame = 3.2 Deg C
.
.
.
98th frame = 158.4 Deg C
99th frame = 160 Deg C
When you create your 100 images, make sure you create your 0th frame to depict a reading of 0 Deg C,
your 1st frame to depict a reading of 1.6 Deg C, your 2nd frame to depict a reading of 3.2 Deg C and so on
until your 99th frame depicts a reading of 160 Deg C.
When you name the files on your PC, it is suggested you name them in the according fashion.
