4. In the GUI software, choose “New Project”.
5. In the window that pops up, name it, choose where it will save, and press “OK”.
6. Bring the images in by right-clicking “Image Resources” and choosing “Add New”.
9. To use an image as the background: a) Choose “Image” under the library window
and drag it onto the gray box. b) Give the image an appropriate name and use the
appropriate size settings to ll the entire screen. c) Select the image background in
“Source”.
10. To add the meters: a) Add in meter images in the same way as mentioned in step
9. b) To resize the images, grab the corners or sides and stretch them to the
necessary size. c) Once nished, click on the individual meters and name them for
easy access later.
7. Navigate to the location where the pictures are stored and select the picture to
bring in. The image will now appear under image resources in the project browser.
8. To use a color as the background: a) Click on the gray box in the middle of the
screen where the display preview will be. b) Choose the background color in the
“Properties Editor” menu that appears on the right.
11. To add the needles for each display: a) Add in needle images as mentioned in
step 9. b) Position the bottom of the needle to be in the center of the dial. c) Set
the transform origin to the bottom center of the picture in the “Properties Editor”
menu on the right. (This is the xed point that will be the “hinge” that the dial turns
on.) d) Under “Rotation”, change the angle to check how the image will rotate and
verify it is moving in the expected way. (Make a note of the angles where the needle
needs to start and stop.)
Page 3
12. To add the battery gauge: a) Add the gauge photo as mentioned in step 9. b) Drop
the image into position and name it.
13. To make the dials move: a) Choose “rotating needle” under the function setting of
the library and drag it to the gray area to the right. b) Click on rotatingNeedle and
name it appropriately. c) The analogueInput will default to channel one. d) The
visual element is the picture of the needle. e) The angle range is where the needle
needs to start and stop. (Noted in step 11.)
16. To test the app, click File>Preview or press F5 to bring up the simulation window.
Inputs can be simulated in this screen to verify that everything is working properly.
17. Once satised with the simulation, click File>Upload or press F6 with the meter still
plugged in to send the app to the display.
14. Click on analogueInput and assign the wanted channel to control the mph_needle.
Here, also set the voltage range and what value that voltage range translates to on
the display. Follow the same instructions to add any other needle channels.
15. To add bar graph ll graphics, drag in the “ll meter” function and another
analogueInput and follow the directions above.

MOUNTING
1. Punch out a rectangular hole in the panel of the enclosure 4.6˝ x 3.07˝ (117 x 78
mm).
2. For panels between 0.04˝ and 0.12˝ (1 and 3 mm) in thickness, use the integral
clips to attach the SPPM2 to the panel.
3. For panels between 0.01˝ and 0.15˝ (0.5 an 4 mm) in thickness, place the gasket
around the bezel of the display, slide the display through the front hole in the panel,
and attach the mounting clip from the rear, as shown in Figure 1.

To minimize offsets, it is best practice to connect the analog grounds directly to the
meter pins (PL11) or screw terminals (TBLK1). The SPPM2 uses a programmable gain
amplier (PGA) together with a 16-bit analog to digital converter (ADC) for its analog
voltage measurements. The PGA is automatically set when the analog range of a
channel is input into the design software.
The table below shows the maximum resolution of the SPPM2’s analog measurements
across a number of voltage ranges

MEASURING A 4-20 mA CURRENT
The 4-20 mA signal should be connected as for “Measuring an Analog Voltage”, but
a jumper link should be placed across pins PL8 for each analog channel being used.

Scaling: The sense resistors used are 110Ω. Therefore, in software scaling, 4 mA
equates to 0.44 V and 20 mA equates to 2.2 V. (Note: Transmitter terminals + or – must
be isolated from the power supply.).
