Akai MPD232 Service Manual

LED tests
There are a number of LED tests in the MPD232 Manufacturing Test.
– Red Pad LEDs
– Green Pad LEDs
– Blue Pad LEDs
– Red Seq LEDS
– Green Seq LEDs
– Button 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_LEDS_ON test where all the LEDs are lit. This is to help check for faulty
LEDs.
