When you power-on ("boot") an LX-300, this software is automatically loaded. During the boot, it performs a number of diagnostic tests, initializes the hardware, and loads the latest control software. If the boot software encounters any non-recoverable (fatal) errors, it will attempt to display the error. The following boot sequence description should assist you in identifying at which point the error occurred and what caused it.

Performs a Power-On Self Test. B. Performs hardware initialization. C. Reads the Frame ID switch setting on the LX-DSP, LX-EXP, and LX-VRA modules, and then for DSP IDs 01 through 32: • Loads and executes the system firmware program. • OR, if there is no system firmware, waits for system firmware to be uploaded. A. Power-On Self Test For all other Frame IDs, the DSP performs special functions as described in Special DSP ID Codes (p. 16). These steps are described in detail in the sections that follow. A. Power-On Self Test During the first stage of power-on boot, the LX-DSP processor module waits for the LX-300 power and bus signal conditions to stabilize. It then tests its main SDRAM memory circuits and loads the next stage of boot software. 1. Power is turned on. 2. Wait for the LX-300 circuits to fully power-on and stabilize. • Wait 1/2 second. The Watchdog LED is red. • Start a watchdog timer that will turn the LED red if the system stalls. • If the Watchdog LED does not turn green, the LX-300 is completely non-functional and must be returned to Meyer Sound for repairs. 3. Test the SDRAM memory. • Green Watchdog LED: success. • Red Watchdog LED: failure. 4. Initialize Hardware. Proceed to B. Hardware Initialization (p. 8), below. POST Failure In the event of a POST error, rebooting the LX-300 may resolve the issue. Repeated failure indicates the LX-DSP processor module is non-functional. Replace the LX-DSP with a known-good module. Return the non-working module to Meyer Sound for repairs. Multiple LX-DSP failures indicate a problem with the LX-300 itself. Replace the LX-300 with a known-good LX-300. You may re-use the modules from the non-working LX-300, but they should be treated as suspect until proved good (they may have been damaged by the non-working LX-300.) Return the non-working LX-300 to Meyer Sound for repairs. Multiple LX-300 failures indicate a problem with the facility power system. This is a situation beyond the scope of this manual. Facility power problems may result in non-warrantable damage to your LX-300s. B. Hardware Initialization 1. Prepare boot monitoring: set Watchdog LED to green. When possible, the LX-300 will display an error code when the boot process fails. It does this by blinking the Watchdog LED and by using the Frame Status display. Most errors will ...
