This is because there are too many other variables that may influence the processing environment, including differences in motherboard design and the particular combination of other devices involved.

TEST MODE
*Tools required q A personal computer having environment in which SMPU64 can operate (for further information, refer to the Specification) q USB cable q A pair of tweezers (for grounding) q MIDI cable 1. Entering test mode 1.1 Using tweezers, connect the pin 5 of IC1 to ground path (hold the tweezers in this way until test 5). 1.2 Connect S-MPU64 to the PC via USB. 1.3 The unit is now in the test mode and turns on all 9 LEDs for a moment. 2. Identifying version The LEDs MID IN (red) and MIDI OUT (green) light for 1-2 seconds to identify the version as described in the Version Indication table shown below. 3. Testing ICs 3.1 When all ICs are operating correctly All LEDs are lit. 3.2 Indicating failure IC(s) A blinking LED indicates that the device shown in the table below is defective and that the test mode is interrupted. The LED remains blinking until power is turned off. Turn off power, replace the IC. Re-enter the test mode by repeating step 1. Blinking LED USB (red) MIDI IN3 (red) MIDI IN4 (red) Defective device CPU (IC2) SRAM (IC3): erase, write, read Program transfer from flash memory (IC4) to SRAM (IC3)

VERSION TABLE
MIDI IN and MIDI OUT LEDs (lighting) express the version in a binary number. : on, : off

/ Ver. 1.00

/ Ver. 1.10

/ Ver. 1.20

/ Ver. 1.30

/ Ver. 1.40 : : : : / Ver. 1.80

4. Testing LEDs 4.1 All LEDs turn on and off, from USB to MIDI IN1, one by one at a time. 4.2 All LEDs light. 5. Testing MIDI ports 5.1 Remove the tweezers to disconnect pin 5 of IC1 from ground reference. 5.2 Connect MIDI INs 1-4 to MIDI OUTs 1-4 in this order, one connection at a time, through a MIDI cable. Corresponding MIDI IN LED should light.
