It is essential that you have a copy of the users manual as this contains the complete operating i

15、nstructions. The HUI was designed to work with digital audio workstations (DAWs). It allows the human user to have the correct touch and feel of a true audio mixer, instead of trying to use a mouse and keyboard to control the software. To service the HUI, technicians should be familiar with op-amp b

16、ased and discrete analog circuitry, digital troubleshooting, and the operation / application of mixing consoles and MIDI systems.

Self-Demo Procedure This de

28、monstration will make sure the HUI lights up correctly and works properly. If successful, it shows that most of the HUI hardware is working lovely. 1. Turn on the HUI by pressing the POWER rocker switch located on the rear panel. 2. While the display reads “Welcome to the HUI”, simultaneosly press t

29、he CTRL and ALT buttons (located in the lower left area of the front panel). The self-demo will begin and continues as long as the HUI is powered up. 3. To leave the self-demo, turn off the POWER switch. System-Test Procedure This is a more involved test procedure which requires a few pieces of extr

30、a equipment. The tests usually output a pass or fail message to the VFD, however several tests require the human user to visually verify the functional operation of the LEDs, meters, VPots, switches, etc. These routines do not test any of the audio portions of the HUI. Equipment Requirements for som

31、e tests: - MIDI cable - Footswitch (normally open momentary switch) on a cable with a 1/4“ Jack - TRS shorting plug (The TIP, RING, and SLEEVE are shorted together) - DB9 shorting connectors for the SERIAL and EXPANSION ports The RS232 and EXPANSION ports tests require connectors with pins 2 and 3 s

32、horted. The RS422 test requires a connector with pins 3 and 7 shorted and also pins 8 and 2 shorted. - Baud Rate test cable Follow the test procedure on the next few pages. 1 2 3 4 5 6 7 8 9 1 2 3 4 5 1N916 9-PIN D-SUB FEMALE 5-PIN DIN NORMALLY OPEN BAUD RATE TEST CABLE FOOTSWITCH CABLE HUI HOME 20

33、The system-test procedure Before powering on the unit to be tested, install the TRS shorting plug into its FOOTSWITCH IN 1 jack (on the rear panel) and the footswitch cable into FOOTSWITCH IN 2. To enter the test routines the user must switch on the power, wait for a character display on the VFD, an

34、d then press the footswitch. The VFD will display that the fixture is in self test mode, in about 3 seconds, by showing a menu of test categories to choose from. After entering the test mode, the VFD will display two rows of selections for tests. These are the top level menu selections. One row will

35、 be flashing indicating that these selections are instantly available by pushing the corresponding switch in the DSP section in the upper right top area on the HUI. There are 4 VPots in the DSP section, each has a SELECT switch above it. These switches correspond to the columns which are displayed i

36、n the VFD and will be called the selection switches in this procedure. There is one additional switch to the right of these (the INSERT/PARAM switch) which will toggle the flashing row in the menu and is also used as an exit switch. Pressing the selection switch for the test in the flashing row will

37、 select that test. As an ex- ample, if you wanted to test the meters you would select LEDs on the flashing menu by pressing the switch that is directly below the column that LEDs is in, then you would select Meters, which appears in the second menu after making the first selection, in a similar mann

38、er. If the test you want is not in the flashing row you can toggle to the row you want by pressing the INSERT/PARAM switch on the right of the 4 SELECT switches. If you wish to exit before running the test press the exit switch (the INSERT/PARAM switch). Once you are within a test, an exit is usuall

39、y done by pressing the footswitch. On the following pages is a list of all tests that should be done. They are arranged according to their appearance in the top level menu. Under each numbered title are the names of the individual tests to be done. They can be done in any order as long as the test p

40、erson makes sure to do all of them. Some tests are redundant with others in this procedure, when this is the case it will be indicated so it will not be necessary to duplicate tests. Power on the unit after you have installed the test cables and are ready to test. 1.0 System ROM RAM EEPROM 1.1 ROM:

41、Select System on the flashing menu and ROM in the second menu. The Brain board in the HUI verifies the ROM is working. 1.1.1 Verify the VFD displays D6E7 in its lower right corner when the test is done. This test exits on its own. 1.2 SRAM: Select System on the flashing menu and SRAM in the second m

42、enu. The Brain board in the HUI verifies the RAM is working properly. 1.2.1 Verify there are no error messages in the VFD returned from the self test. Press the footswitch to exit. HUI HOME 21 1.3 EEPROM: Select System on the flashing menu and EEPROM in the second menu. The Brain board in the HUI ve

43、rifies the EEPROM is working properly. 1.3.1 Verify there are no error messages in the VFD returned from the self test. This test exits on its own. 2.0 LEDS Switch LEDS Meters 2.1 Switch LEDs and Color Verification: This test flashes all LEDs to show the user any possible unlighted LEDs. Select LEDs

44、 on the flashing menu and SW LEDs in the second menu. The AUTO button in each of the 8 channels has a tri-colored LED. Make sure the appropriate color flashes during its color set (it will not flash during yellow mode). 2.1.1 Check each and every LED carefully to see that there are no blemishes on t

45、he buttons or in the windows for the LEDs. Make sure that each LED is properly aligned under its button window. Also verify that all LEDs are of even brightness with each other. 2.1.2 Press the footswitch and the test flashes all the red LEDs while leaving all the rest of the LEDs on. If a different

46、 color than red is flashing then the unit needs repair. 2.1.3 Press the footswitch and the test flashes all the green LEDs while leaving all the rest of the LEDs on. If a different color than green (except Play) is flashing then the unit needs repair. 2.1.4 Press the footswitch and the test flashes all the yellow LEDs while leaving all the rest of the LEDs on. If a different color than yellow is flashing then the unit needs repair. Press the footswitch to exit this test. 2.2 Meters: This test sequentially illuminates all 12 segments of all meters in a d
