QL Series II Interface firmware V2.06
V2.0x adds LXI v1.4 (core 2011) support to the LAN interface. Note that updating from versions prior to 2.0x will cause all LAN settings to return to defaults. Version 2.04 included LXI/LAN code updates to fix mDNS network dropouts. Version 2.05 fixes an issue with single channel units turning off the output when entering remote mode. Version 2.06 fixes bugs with the OPALL command and network configuration settings.
