CSS Common Custom Solution Postponed FDI load Johnny

CSS Common Custom Solution Postponed FDI load. Johnny Hansen, GTO December 2005

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)

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 Canta 4 product cannot be converted (upgraded) to a Canta 7 product. – A Canta 7 product can be converted to a Canta 4.

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 formfactor and model from order. (CIC - CIC-B – ITC-D - ITE etc. ) Complete final assembly of instrument according to order form. Determine appropriate AUDIOmaster Test Program (add options etc. ) (. TPI) Determine Gain/Output requirements. (High Power or Normal power) Select CCS faceplate assembly in appropriate Form Factor and Power settings from stock. Determine test mode and select options. Run the selected test program as normally. [ Final / Repair / Fp ] (TC / VC / PB etc. ) upload the correct FDI into the instrument) (TPI will automatically 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 6 different situations are shown in next slides Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSLDUT >= MSLTPI ? Y Continue test and FDI load N All AUDIOmaster TPI’s has a MSL: Current MSL levels are: Re. Sound Metrix = 12 Re. Sound Pixel = 8 Re. Sound Plus 5 = 5 CCS Generic faceplate assemblies all loaded with MSL = 25 Abort test and FDI load

MSL procedure – exmp. 1 CCS (generic) faceplate under test 25 TPI reads MSL of the Device Under Test (DUT) Result: YES Bigger or equal to • • 5 ? (MSL = 25) Select AUDIOmaster TPI and start test. (normal new production) TPI compares MSL of DUT with own MSLDUT >= MSLTPI ? Continue test and FDI load Load Plus 5 image into instrument CCS instrument is now a Plus 5 New MSL in device = 5 Y Continue test and FDI load N Example: Plus 5 ITC-D selected (MSL = 5) MSLDUT = 25 MSLTPI = 5 Abort test and FDI load

MSL procedure – exmp. 2 Plus 5 RP 70 -D BTE after repair. 5 Bigger or equal to 12 ? (MSL = 5) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) (attempt on upgrading) MSLDUT TPI compares MSL of DUT with own MSL >= MSLTPI ? Y Continue test and FDI load N Example: Metrix MX 70 selected (MSL = 12) MSLDUT = 5 Abort test and FDI load MSLTPI = 12 Result: NO • • Abort test and FDI load “Upgrading” not allowed Give warning to operator MSL in device still 5

MSL procedure – exmp. 3 (mistake on TPI select) Result: YES Plus 5 ITC RP 30 after repair Bigger or equal to and instrument hardware. 5 ? (MSL = 5) Select AUDIOmaster TPI and start test. • Continue test and FDI load • Loads a Plus 5 RP 50 -D image in RP 30 • Test fails – mismatch between specs 5 TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL • New MSL in device still 5 • Can be corrected with new test with correct TPI MSLDUT >= MSLTPI ? Y Continue test and FDI load N Plus 5 RP 50 -DP selected (by mistake) (MSL = 5) MSLDUT = 5 MSLTPI = 5 Abort test and FDI load

MSL procedure – exmp. 4 (critical mistake on TPI select) Result: YES Metrix ITC MX 50 -DP after repair Bigger or equal to TPI reads MSL of the Device Under Test (DUT) Model and algorithm packages. 5 ? (MSL = 12) Select AUDIOmaster TPI and start test. • Continue test and FDI load • Loads RP 50 -DP image in MX 50 -DP • NB! Test PASS but mismatch between 12 TPI compares MSL of DUT with own MSL • New MSL in device is now 5 • Cannot be corrected with new test MSLDUT >= MSLTPI ? Y Continue test and FDI load N Plus 5 RP 50 -DP selected (by mistake) (MSL = 5) MSLDUT = 12 MSLTPI = 5 Abort test and FDI load

MSL procedure – exmp. 5 (Brand switch - future use) Result: YES Metrix ITC HP faceplate (re-plated) 12 Bigger or equal to 10 ? (MSL = 12) Select AUDIOmaster TPI and start test. TPI reads MSL of the Device Under Test (DUT) • • TPI compares MSL of DUT with own MSLDUT >= MSLTPI ? Continue test and FDI load Loads Beltone One image in Metrix Re. Sound Metrix is now Beltone One New MSL in device is now 10 Y Continue test and FDI load N BELTONE One ITC HP (MSL = 10) MSLDUT = 12 MSLTPI = 10 Abort test and FDI load

MSL procedure – exmp. 6 (Brand switch - future use) Result: YES Beltone One ITC-D HP 10 Bigger or equal to Beltone One 8 ? (MSL = 10) Select AUDIOmaster TPI and start test. • Continue test and FDI load • Loads Re. Sound Pixel image into TPI reads MSL of the Device Under Test (DUT) TPI compares MSL of DUT with own MSL • Beltone One is now Re. Sound Pixel • New MSL in device is now 8 MSLDUT >= MSLTPI ? Y Continue test and FDI load N MSLDUT = 10 Pixel PL 30 -DP (MSL = 8) MSLTPI = 9 Abort test and FDI load
