Switch off supply before opening any of the covers.
4.6 Updating software
The 973 SmartRadar LT is a multiple microprocessor gauge. If a new software version is installed, or an
option board is added, it may be necessary to replace one or more of the program memories (EPROM) on
the processor boards of the 973 SmartRadar LT.
The actual version of the installed software can be checked with item
SV
. In case of a software update,
check whether the contents of item
SV
correspond with the documentation accompanying the new software.
Because of the strict relationship between the various processor boards, it may become necessary to
replace the memory of more than one processor board. Such a change may require an initialization of the
NOVRAM, followed by re-programming the user parameters.
The table below gives the software versions for the different processor boards which can operate together.
Processor ICU board ICU board RFB-2 / DAB Optional board
(XPU-2 part) (APU part) board
Software XPU K1.0 APU B1.0 DAB B1.0 HPI A1.0
version HPO A1.0
Note:
Because software updates of different processor boards may be required in the future, this table may not
be up to date. For further information, contact Enraf or the local representative.
If a new DAB / APU software version from a different row in the table above is placed in the SmartRadar LT,
the Antenna parameters must also be updated. This can be done with a separate script file named:
“873AUD03.ESF” of the Ensite service tool.
Proceed as follows:
1) Start up Ensite and make a log file of the gauge from which the software is going to be replaced.
2) Run the script file 873AUD03.ESF. This file is (should be) placed in the ESF sub-directory of the
Ensite program and then it can be selected by the name: “873 AU download”. This file stores data of
the Antenna and RFB-2 calibration SEEPROM in a file called: “<
TI
>.AUD”, located in the Tank
subdirectory under: [drive]:\ENSITE\DAT\<
sitename >.SIT\. (
TI
is the 6 character tank identifier name,
<
sitename > represents the given site name when the scanned site data was stored and [drive] is the
C- or D- drive from which the Ensite service tool is running).
3) Request to following data with the service tool Ensite:
• Transmission address (item
TA
)
• Tank identifier (item
TI
)
• Transmission speed (item
TS
)
• Gauge type (item
GT
)
Note these values for later use.
4) Switch off mains supply and open cover of electronic compartment.
