How to use the diagnostic disk
- Use a computer with a floppy drive to copy the diagnostic disk files to a blank formatted floppy disk (High-Density, 1.44MB).
- It may be preferred to format the disk using the console (Setup -> Disk -> Format Disk).
- Turn off the console, and then insert the disk.
- Turn on the console and wait for the disk to load.
- Select the desired diagnostic test and press [Enter].
- Wait for the test to load.
- Turn off the console after each test has completed.
Do not press S7 while in the Diagnostic test file selection menu. This will overwrite your console software so that the console will boot to the selected item every time the console is turned on.
Tests
Test Summary | Details |
DMX - Sends a DMX signal to all 512 addresses with each port | |
DRAM - Test DRAM Warning: This erases the SRAM (show memory) |
Details: The test is divided into parts, tests and passes. The parts are: zeros: write 0's to all locations ones: write 1's to all locations bit n each step in a checkerboard test The tests consist of all the parts run with byte, short, word or quad word accesses. Each pass consists of all the tests run once. The test runs forever. The error display has three columns: errors: total number of errors addr mask: indicates which address lines the errors occurred on data mask: indicates which data lines the errors occurred on If only 1 or 2 bits are set in the address mask, more than likely the problem is an address line problem. The same holds true for the data mask. |
SRAM - Test DRAM Warning: This erases the SRAM (show memory) |
The test is identical to the DRAM tests. |
Flash - Tests Flash (Do not power off console or remove disk until testing is complete) |
This tests the flash EEPROM. This is not a very exhaustive test because of the limited write capability of EPROMs. It is non-destructive. |
Face - This tests the face panel functions, RFU, and Remote inputs | If you are running an Insight or Impuls, the display will be funky until you press [PARK]. The display has several sections.

Diagnostic Test "Help" Notes
The "HELPFILE" is what stores the notes that are displayed at the bottom of the Diagnostic Disk menu when each item is selected.
These must be written in the same order that the files appear on the disk.
Each file gets 5 lines. The top line must be the file name written identical to the actual file name. The following 4 lines can say whatever.
