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.
