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 for the main DSP before the LX-300 will work again. You will need a network connection to an LX-ELC module on the system or a serial connection to an LX-COS module on the system.
1.Start with the LX-300 powered off.
2.On the rear of the LX-300 locate the LX-DSP module. It is in slot 0, in approximately the middle of the rear panel. Make note of the Frame ID, so that it can be returned it to the original setting after this procedure. Valid ID settings for normal operation of the LX-DSP module are in the range of 01 to 32.
3.Set the LX-DSP module ID switch to one of the following codes depending on the action desired.
ID 
Action
83 
Erase LX-ELC Flash
87
Erase System Flash
88
Erase NV RAM
89
Erase User Flash
4.Power the LX-300 on. You will see the Frame Status window on the front of the LX-300 display one of the fol- lowing messages:
Message | Meaning |
*EET | Erase EtherTracks Flash (ID 83) |
*ESF | Erase System Flash (ID 87) |
*ENV | Erase Non-volatile RAM (ID 88) |
*EUF | Erase User Flash (ID 89) |
5.After the Erase has completed, the status display will show "REBO" (for reboot). Power off the LX-300.
6.Set the Frame ID back to the original setting (01 to 32).
7.Power the LX-300 on.
If you have erased the System Flash, the system status display will show /EP\ indicating that the LX-300 is running from the minimum operating system in the EPROM. You must reload the main DSP firmware to use the LX-300: see Upgrading a System from EPROM Mode (p. 13) for instructions on performing this operation.
If you have erased the LX-ELC Flash, the system status display a series of messages listing the missing ELC flash files. You must upload the missing files as well as sending a mixer configuration with the IP Address Send checked in order to load an IP address into the module. The default IP address is set to 192.168.0.(100+Frame ID), so Frame ID 01 would have a default IP address of 192.168.0.101.
