ULTRAMIX SELF TEST PROCEDURE
Setup: Connect the MIDI OUT jack of the DUT to the MIDI IN jack of the DUT. Use Control Interface Port test adapter to connect the TX to the RX signal at the CIP1.
Action: Apply power to DUT. 2
RAM Test: (Tests SRAM and EEPROM) Response: PASS: The three LEDs on the front panel will light up sequentially (MIDI first, then Bypass, then Local). All LEDs will then go off and the Bypass LED will come back on, indicating that the DUT is in its default power-on mode and is ready for normal operation. FAIL: The bottom two LEDs (Bypass and Local Mode) will flash quickly and the DUT will hold in this failure mode.
IO Port Test: (Tests MIDI IO and Control Interface Port IO) Action: Response: Simultaneously apply power to DUT and PASS: All three front panel LEDs should flash at about 4 Hz.4 depress Local Mode switch.3 FAIL: One (or more) of the LEDs remain unlit. Bottom (Local Mode) LED = CIP failure Middle (Bypass) LED = MIDI port failure
Switch Test: ( Tests the front panel switches ) Action: Response: This is a continuation of the IO Port Test. When a switch is depressed, its companion LED will go off as long Depress each switch, one switch at a time. as the switch is engaged. Release the switch and the LED should resume flashing.

C ontrol I ntreface P ort If DUT is already powered up, remove power then reapply power. See Note 2 The LEDs will not be flashing in sync, but that�s ok.
