LX-300 Start Up Routine Overview 7 A. Power-On Self Test 8 B. Hardware Initialization 8 C. System Firmware Startup 9 EtherTracks Startup 10 The LX-300 contains a digital signal processor and built-in software. When you power-on ("boot") an LX-300, this software is automatically loaded.
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.
• Display "INIT" briefly on the Frame Status. • Display all front panel lights for one second. • Display "E1V6" on the Frame Status. The two digits correspond to the EPROM software version number. • Show the Frame ID in the Frame ID display.
4. Await EPROM upload. Refer to the "Matrix3 Repair Procedures" section for more information. Subsystem Initialization Failure Subsystem initialization failure will usually result in a general system failure. The system will display an error message (see LX-300 Error Codes (p.
Firmware Updates Before You Begin 11 Firmware Update Procedures 12 Special DSP ID Codes 16 The LX-DSP, LX-ELC, LX-VRA, and LX-EXP modules load operating system files into RAM during power-on. These files are stored in flash memory on each of the modules.
loading the file again. If you use the Erase Flash command for the EtherTracks module and then switch off the LX- 300 (or power fails), You will have to use VirtualLX and a serial connection to an LX-COS module to recover.
After you click OK , a blank configuration will be sent to the hardware. This is to prevent audio processing while firmware is uploaded. Another dialog box will appear, allowing you to locate the firmware file(s). All modules should be using the same firmware version as CueStation.
This assumes that the firmware in the LX-DSP and LX-ELC has been completely erased. You must have an LX- COS Communication / Synchronization module in your system since the EPROM in the LX-DSP module is only able to connect to a serial port.
4. In the drop-down menu, select Use TCP Connection . An alert box will open with a "System Reset Warning". This is a normal caution. Click Yes . 5. In CueStation 4 open the Mixer Configuration window. Select Configuration > Upload Firmware .
Special DSP ID Codes The ID switch on an LX-DSP module may be used to force the LX-300 to erase flash memory areas in the DSP, EXP, and ELC modules. You may need to do this if flash memory has become corrupted, or if there is a problem after uploading system flash.
Erasing Flash Memory Caution If you erase the LX-ELC flash, you must upload replacement firmware files to the LX-ELC module before it will work again. You will need an LX-COS module for serial connection or a network connection to an LX-ELC module on another LX-300 in the system that has not been erased.

Matrix3 Repair Procedures Overview 19 Replacement of Power Fuse 19 Removal and Installation of Modules 20 Physical repair of the Matrix3 system is limited to replacement of expansion modules. Overview Skills Required • Removal of LX-300 from audio system.
Removal and Installation of Modules All modules must be installed to a valid slot position. Incorrect assignment of modules to slots may result in hardware failure or poor performance, although the modules themselves will not be damaged. Caution Circuit card assemblies contain Electrostatic Discharge Sensitive (ESDS) components.
8. Power on the LX-300, and observe the System LED and Frame Status displays. A detailed description of the boot process is provided in the LX-300 Start Up Routine (p. 7). 9. Within four seconds of power-on, the System LED must display and remain solid green (except after the first all-indicators-on test, when it will momentarily flicker red).

LX-300 Maintenance Overview 23 Recommended Schedule 23 Inspection and Maintenance Procedure 23 Operational Testing 24 Dust, heat, humidity and power surges are the most significant dangers to the system and its components. For best performance, the Matrix3 should be operated in a cool, low-dust, low-humidity environment.
Important Tighten the left-hand captive machine screws on double-width modules first, to prevent warping the panel. The chassis will be secured to its rack using four captive machine screws, located at either edge of the front panel. There may be optional mounting points at the rear of the LX-300.
Hardware Specifications LX-300 Specifications 25 Power Requirements 26 Component Specifications 27 This chapter presents detailed electrical, mechanical and physical specifications for the Matrix3 and its modules. LX-300 Specifications This illustration shows a typical Matrix3 back panel.
Operating Environment 0 ° to 40 ° Celcius (32 ° to 100 ° Fahrenheit). 5% to 95% humidity, non-condensing. Low dust levels. Warning The internal temperature, as reported in the System Status window, is typically 10º C hotter than the operating en- vironment.
