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. 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 di

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 ful

C. System Firmware Startup • 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. This is a two-digit number corresponding to the Frame ID value set on the LX-DSP module. • Show the appropriate Expansion LEDs, indicating the expansion slots which have modules installed in them. When the boot process has made it

EtherTracks Startup 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. 43)) and "REBO", and flash the Watchdog LED red and green. Subsystem failure usually indicates a failure in the LX-DSP or LX-LNK modules. Some subsystems can fail without causing a system failure. If th

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. Because these files are stored in the module, they are referred to as “firmware”. The version number for the firmware files and CueStation must match. If you upgrade to a new version of CueStation, you must also upgrade all firmware files. Firmw

Firmware Update Procedures 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. If part of the erase procedure had already been started, the flash memory could be corrupted or incomplete and the LX-300 will not start up properly. To remedy this situation you must force an erase of the problem firmware file using the LX-DSP modul

Firmware Update Procedures 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. There are five firmware files in each release: lx300_vx_x_x_xx.csf (where "x_x_x_xx" is the version number) The lx300___.csf file has two firmware files for the LX-DSP module. et_boot_v_x_x_x

Firmware Update Procedures 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. Important If there is an LX-EXP module in the system with an ID set higher than 32, it will not accept firmware while in EPROM mode. Change the ID to a number less than 32 before beginning the firmware upload. For newer computers w

Firmware Update Procedures 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. Make sure that you comply with the instruction in the alert box that opens and then click OK. 6. A file requester window will open. Navigate to the location with the CS4 firmware files. Note Files can be sent in any order as long as

Special DSP ID Codes 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. Both situations are rare, and erasing flash memory is not required in normal operation. Try the Erase Flash commands first as they will allow you to erase and then replace flash files without requiring a serial co

Special DSP ID Codes 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. In CueStation 4 you will have to use VirtualLX in order to connect to a LX-300 with an erased ELC module. If you erase the System Flash, you must upload replacement firmware

Removal and Installation of Modules 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. Take appropriate precautions when handling expansion modules. Module Removal 1. Power off the LX-300. 2. Label all cables attached to
