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 mai ...

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 versi ...

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 ...

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 ...

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 firmw ...

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 operati ...

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 Virtual ...
