Postponed FDI load.

What is postponement ?

Postponing the branding and naming of the instrument after final assembly.

Loading model specific software as late in the manufacturing process as possible.

Using same hardware for many product families.

Why postponement ?

Saving manufacturing costs

Lowering inventory SKU’s

Ease inventory handling

Benefit from CCS (Common Custom Solutions)

Postponed FDI load to during final test

Model Series Level (MSL) - bullet points

Branding hardware (Hybrids)

All AUDIOmaster TPI’s checks MSL

Always go to same or a lower MSL level

Never go to a higher MSL level.

Generic faceplates starts on the highest MSL level (25).

MSL – how it works

Model series level is a way to ensure that instruments are not upgraded in software levels.

AUDIOmaster Test Programs will allow for instruments to go to a lower Model Series Level.

Same functionality is known in earlier product families:– A Canta4 product cannot be converted (upgraded) to a

Canta7 product.– A Canta7 product can be converted to a Canta4.

Model Series Level check

Every test program have a MSL

Test program read MSL from device

Compare with MSL in test program

If test program MSL is equal or lower than device MSL then proceed otherwise halt.

Postponed FDI load - flow chart

Read order form

Determine form- factor and model from order.(CIC - CIC-B – ITC -

ITC-D - ITE etc. )

Determine Gain/Output requirements.

(High Power or Normal power)

Select CCS faceplate assembly in appropriate Form Factor and Power settings from stock.

Complete final assembly of instrument according to order form.

(add options etc.)

Determine appropriate AUDIOmaster Test Program

(.TPI)

Run the selected test program as normally.

(TPI will automatically upload the correct FDI into the instrument)

Determine test mode and select options.

[ Final / Repair / Fp ](TC / VC / PB etc.)

AUDIOmaster will perform necessary HI-calibrations according to selection of test mode and instruments model. (Input-, Output-, IAD calibration)

AUDIOmaster will test instrument and generate a test report with the correct FDI loaded.

AUDIOmaster will set the appropriate MSL (Model Series Level) according to selected TPI

MSL procedure

Select AUDIOmaster TPI and start test.

TPI reads MSL of the Device Under Test (DUT)

TPI compares MSL of DUT with own MSL

All AUDIOmaster TPI’s has a MSL:

Current MSL levels are:ReSound Metrix = 12ReSound Pixel = 8ReSound Plus5 = 5

CCS Generic faceplate assemblies all loaded with MSL = 25

Result: YES • Continue test and FDI load• Load Plus5 image into instrument• CCS instrument is now a Plus5• New MSL in device = 5

Result: NO • Abort test and FDI load• “Upgrading” not allowed• Give warning to operator• MSL in device still 5

Result: YES • Continue test and FDI load• Loads a Plus5 RP50-D image in RP30• Test fails – mismatch between specs

and instrument hardware.• New MSL in device still 5• Can be corrected with new test with

correct TPI

MSL procedure – exmp. 4 (critical mistake on TPI select)

Result: YES • Continue test and FDI load• Loads RP50-DP image in MX50-DP

• NB! Test PASS but mismatch between Model and algorithm packages.

• New MSL in device is now 5

• Cannot be corrected with new test

MSL procedure – exmp. 5 (Brand switch - future use)
