Manufacturing Testing of MPD218 using ADT1
15 October, 2014
This document is intended to describe the operation of the ADT1 Manufacturing Test
application for the Production Testing of MPD218.
Terms
MPD218: A US Pad Controller. Also known as AD18.
ADT1: A Manufacturing Test application that runs on Windows computers.
Hardware setup
Connect MPD218 US to Windows Computer running ADT1 Manufacturing Test
application.
Software setup
The Manufacturing Test of AD18 requires the following files
–ADT1.exe: executable file (v.0.7.3 or later)
–AD18.png: image file
–AD18.xml: test file
These files should be arranged so that the product specific files (AD18.png and AD18.xml)
are in a folder called “tests” that resides in the same folder as the ADT1 executable as
below.
Running the Manufacturing Test Application
Port selection
Different language versions of different Operating Systems have different ways of
identifying MIDI ports and audio hardware. For this reason, ADT1 allows the Tester to
select these ports when the program is first run. Once a subtest has been successfully
completed, it should no longer be necessary to select these ports even if a different unit is
being tested.
The ports that need to be selected depend on the sub-tests that are being performed for
that product. In addition to the main US -MIDI port, the Manufacturing test for MPD218
requires that a port be selected for the MIDI loopback test.

Device Test selection
When the program starts on an English language version of Windows XP, the Tester
should be presented with the following “Port/Test Chooser” window.
Select the correct port and test and click “OK”. This selection should only need to be done
once when the program is first run.
User Interface
The Main Test screen has a representation of the Device Under Test.

Subtest buttons
At the bottom of the screen are some buttons that correspond to “sub-tests”. These might
be tests of faders, LEDs, etc. The button will be
–grey if the subtest has not started
–yellow if the sub-test is in progress
–green if the test has subtest has completed successfully
–red if the subtest has failed.
Normally the order of the test will follow the order of the subtest buttons, but it is possible
to change the order of the tests by clicking on the buttons. This can be useful if a test is
accidentally failed.
When the the right-most subtest is completed, the Test Application will loop back to repeat
any tests that have not completed successfully.
The option to write a Serial Number into the Device Under Test will not be offered until
every subtest has been completed successfully (i.e. every subtest button is green).
Serial Number
When a test starts, the Serial Number of the MPD218 will be read and displayed in the
bottom left corner.
The Serial Number will also be read from the MPD218 and displayed after Serialisation
has completed.
Version Number
The version of the firmware will be displayed in the bottom right hand corner.
Indicators
Wherever possible the ADT1 Manufacturing Test app will prompt the Tester. This might be
to show which LEDs should be flashing, which buttons should be used to confirm the test
result or which fader, knob, etc. has been tested.

Tests
LED tests
There are two LED tests in the MPD218 Manufacturing Test.
–utton LEDs
–Pad LEDs

In each case, the ADT1 Manufacturing Test app will send a message to flash LEDs on the
MPD218. The User interface will indicate which LEDs are flashing and what colour they
should be. The Tester should indicate whether the test passed by pressing the UI controls
indicated by the “bubble” messages.
–Test Passed: press the control indicated by “PASS” bubble message.
–Test Failed: press the control indicated by “FAIL” bubble message.
The LED Test has two phases:
1. Animated test where the LEDs are lit one at a time. This is to check for shorts
between LEDs.
2. ALL_LEDS_ON test where all the LEDs are lit. This is to help check for faulty
LEDs.

Button Test
The ADT1 manufacturing Test application will indicate the buttons to be pressed. The
Tester should individually press and release the indicated buttons.
When the ADT1 manufacturing Test application detects that the button has been pressed it
will change the graphic symbol on the User Interface and, where possible, it will send a
message to light the LED that is associated with the button on the MPD218.
The buttons can be pressed in any order, but if ADT1 detects two button events at exactly
the same time it will assume that these buttons are shorted together and fail the test.

Pad test
The Tester should firmly press the indicated pad. The test requires that a maximum pad
pressure value is received by the ADT1 Manufacturing Test application.
When the ADT1 Manufacturing Test application detects light pressure it will change the
graphic symbol on the User interface and send a message to the MPD218 to light the
associated Pad LED.
When the ADT1 Manufacturing Test application detects maximum pad pressure, it will
change the graphic symbol to green and send a message to the MPD218 to switch off the
associated Pad LED.

Rotary Encoder test
The Tester needs to turn the encoder first clockwise and the anti-clockwise as indicated by
the ADT1 Manufacturing Test application.
When the ADT1 Manufacturing Test application detects clockwise rotation of the Rotary
Encoder, it will change the graphic symbol on the User interface.

Serialisation
When all the subtest have been successfully completed, the subtest buttons on the User
Interface will be removed and replaced with a text box. This text box should be used to
program the Serial Number into the MPD218.
The Tester can type the Serial Number, followed by Carriage Return, but it is preferred that
a US arcode Reader is used to scan the serial number barcode on the MPD218.
When the Serialisation has completed successfully, the display will update.
–The word “Programmed will appear next to the Serial Number box
–The new Serial Number will appear in the bottom left corner (this is important)
–A green tick will appear next to the Progress ar
–The top line will say “PASSED”

Test Complete - Next MPD218
When a test of a MPD218 is complete, either successful or unsuccessful, it should be
possible to just disconnect that MPD218 and connect the next one. It would not normally
be necessary to reselect the ports as long as the corresponding test on the previous
MPD218 were successful.
