Rev. 3.4.5
• All instruments having the CPU part number 55392 must use the 3.4 or 3.4.5 Application software. Software
revision 3.4 and revision 3.4.5 application software are compatible with the 51477 CPU that uses the original
release BIOS. Details of the new BIOS and 55392 CPU are discussed in bulletin HFA2i-017. If a previous
version of the application software is used with the 55392 CPU board, spurious characters will be seen in the
data input screen displays.
• The 3.4.5 application software has the same issues as the C3.1 revision other than those fixed as indicated
above.
• All instruments having the CPU part number 55392 must use the 3.4 or 3.4.5 DST software. DST software
revision 3.4 and revision 3.4.5 DST software are compatible with the 51477 CPU that uses the original release
BIOS. Details of the new BIOS and 55392 CPU are discussed in bulletin HFA2i-017. If a previous version
of the DST software is used with the 55392 CPU board, spurious characters will be seen in the data input
screen displays.
• The 3.4.5 DST software has the same issues as the C3.1 revision DST other than those fixed as indicated
above.
• For HFA2P version 3.4.6 SSE, the Threshold Parameters Setup menu has been greatly remodeled. The
menu no longer displays alerts when the setting of one parameter conflicts with that of another parameter.
Instead, priority is given to the strategy, second to blue-yellow. Any parameter in conflict with strategy will
be set to its correct value without warning. If only one value for a given parameter is valid for the selected
strategy, then this parameter shall be disabled and set to the valid value.
