CPX Series Interface firmware file V4.08
Updates to the digital bus interface firmware may be made available from time to time. This firmware resides in flash memory and can be updated via the USB interface. The interface firmware version is displayed briefly when the power supply is switched on. This is the second number that is displayed and is in the form "IF X.XX" (EG, "IF 1.01"). This file is a hex file to be used with the Firmware Flash Utility (see link below).
Version 4.0x adds LXI v1.4 (core 2011) support to the LAN interface.
Version 4.07 and 4.08 fix a number of LAN related issues discovered since the release of 4.0x, mainly related to mDNS.
This firmware is common to CPX200DP, CPX400SP and CPX400DP.
Note that updating from versions prior to 4.0x will cause all the LAN settings to return to the defaults.
