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.
ActionID
Erase LX-ELC Flash83
Erase System Flash87
Erase NV RAM88
Erase User Flash89
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:
MeaningMessage
Erase EtherTracks Flash (ID 83)*EET
Erase System Flash (ID 87)*ESF
Erase Non-volatile RAM (ID 88)*ENV
Erase User Flash (ID 89)*EUF
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.
