Manufacturing Testing of MPD232 using ADT1 v0.7.5
3 March, 2015
This document is intended to describe the operation of the ADT1 Manufacturing Test
application for the Production Testing of MPD232.
Terms
MPD232: A US Pad Controller. Also known as AD33.
ADT1: A Manufacturing Test application that runs on Windows computers.
Hardware setup
ADT1 expects the following connections to be made:
1. US connection to Windows Computer running ADT1 Manufacturing Test
application.
2. MIDI IN connected to MIDI OUT for MIDI Loopback Test

oftware setup
The Manufacturing Test of AD33 requires the following files
–ADT1.exe: executable file
–AD33.png: image file
–AD33.xml: test file
These files should be arranged so that the product specific files (AD33.png and AD33.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 MPD232
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.

Midi Loopback port selection
The next Chooser window will allow the Tester to select the port used for the MIDI
loopback test.
Select the correct port 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.

ubtest 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).
erial Number
When a test starts, the Serial Number of the MPD232 will be read and displayed in the
bottom left corner.
The Serial Number will also be read from the MPD232 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
Midi Loopback Test
This test requires a MIDI cable to be connected between the MIDI IN and MIDI OUT
connectors on the rear panel.
Test messages are sent to the MPD232 for transmission from the MIDI OUT connector on
the rear panel. The ADT1 Manufacturing Test app looks for these messages to be received
back on the MIDI IN connector.
This MIDI Loopback test will run automatically with no involvement of the Tester and report
its result.

LED tests
There are a number of LED tests in the MPD232 Manufacturing Test.
–Red Pad LEDs
–Green Pad LEDs
–lue Pad LEDs
–Red Seq LEDS
–Green Seq LEDs
–utton LEDs
–Softkey LEDs
In each case, the ADT1 Manufacturing Test app will send a message to flash LEDs on the
MPD232. 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_LED _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 MPD232.
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.

Fader Test
This test requires that the Test operate the indicated Faders to their minimum and then
maximum limits.
When the Minimum has been reached, the graphic symbol on the User Interface will
change.

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 MPD232 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 MPD232 to switch off the
associated Pad LED.
