Available tests are:
MNB: Main board
1. Main board test
. Performs tests 3-8.
2. Final test
. This test is used in production.
3. EEPROM
test.
4. Quick Flash test
. Performs a quick test of the Flash circuits. The entire memory area
is not tested. To test the entire memory area, perform test number 14.
Flash data is not altered.
5. DSP
. Tests the four DSPs, including external memory and communication between
DSPs.
6. DAC
. Tests the two D/A converters. Outputs a clean sine wave on the four outputs.
Toggle between outputs with
[ Navigator Up ]
or
[ Navigator Down
]
.
7. ADC
. Tests the two A/D converters. Audio connected to IN1 should be heard on
OUT1, IN2 on OUT2 etc.
8. USB
. Shows the USB chip ID. This test can not detect if the USB communication with
a computer is functional. To test USB communication, simply connect the G2 to a
computer running the G2 editor. The editor should automatically find the G2.
9. MIDI
. Tests MIDI communication.
10. Keyboard
. Press one key at a time. Tests velocity response and counts the number
of keys pressed.
11. Pedal
. Tests the control and sustain pedal input jacks.
12. Engine LED test
. Not applicable on G2/G2X.
13. Engine reset test
. Not applicable on G2/G2X.
14. Flash test
. Tests the entire Flash memory area. The test takes approximately 18
minutes to complete. Flash data is not altered.
PNL: Panel board
1. Full
. Performs all of the tests below.
2. Buttons
. Press the buttons as indicated to verify their function.
3. LCDs
. Test the LCD panels.
4. LED´s
. Lights the LED´s in groups in order to verify their function visually.
5. Encoders
. Tests all of the encoders. Requires that each encoder is turned two turns.
6. Pitch stick calibration range
.
7. Pitch stick base value
.
8. Pitch stick
. Tests the pitch stick function.
9. ADC
. Tests the function of the A/D converter on the panel board.
SYS:
Contains system operations. Tests 5-8 are only for internal use.
1. Serial number
. Displays the serial number.
2. Checksum
. For internal use only.
3. FLASH status
. Displays the Flash memory status (erased/not erased/cleared)
4. PWM voltage
. This test can be used to debug the pitch stick calibration voltage.
5. OS killer
. This utility will write random errors into the OS section of the Flash
memory.
6. Erase FFS
. This tool is used to erase the Flash file system section.
7. Erase OS
. This tool is used to erase the OS section of the Flash memory.
8. Erase All
. This tool is used to erase the entire Flash memory.
