5.2 PCB6 µPH8-4 module
Testing a PCB6 (µPH8-4) Flash version module
It is possible to use a µPH8-4 module from a similar type of product for test
purpose, but the serial no. and other important adjusting settings will not match
the product correctly. Therefore it is important to replace the original µPH8-4
module after a test.
The software programable microcomputer version (flash of both APPLICATION and
EEPROM software) can be recognized by having no IC sockets on the PCB.
Another way to identify if a product has the flash version module, is to check if
the PC ServiceTool has APP software flash menus for the specific product.
Replacing the Main microcomputer PCB6 (µPH8-4) Flash version
When replacing the updated PCB6 µPH8-4, it is necessary to read out existing
settings and flash these back into a new PCB6 service module by means of the PC
ServiceTool (can be downloaded from the Retail System/BeoWise section).
This procedure is necessary because the µPH8-4 module contains valuable product
related data such as serial no., PIN-code, monitor settings, program settings etc..
If you have programmed a new service µPH8-4 module, the new PCB6 can only be
used for this specific product, and it must be returned to Bang & Olufsen to be
erased again.
Note
Always disable the PIN-code from the product before reading out data from
µPH8-4 module, or programming a new service µPH8-4 module.
This because the PIN-code system may activate during the flash process.
Not possible to read out product data (or software version) from the Main microcomputer PCB6 (µPH8-4)
Flash version
Check the 5V supply and the signal path for the µPH8-4 module.
In cases where the PCB6 acts ‘dead’, it is necessary to have a new PCB6 pre-
programmed from Bang & Olufsen with the correct serial no. for the specific
product, otherwise it will not work.
Please contact Bang & Olufsen.
The PC ServiceTool
Along with a Cable kit for ServiceTool (3375397), Product Interface Tool (P.I.T.)
(3375055) and eventually USB->RS232 converter (33755) it is possible to flash
update the Pioneer FEP software, and the Master Unit FEP software.
The original interface cable is connected to the Socket Unit, and is going to the
P.I.T. box. From the P.I.T. box a special service interface cable with grey plugs, goes
to the Master Unit. The PC with the ServiceTool software is connected to the P.I.T.
box. On the P.I.T. box, you are able to select which software you want to flash
update via a switch.
The PC ServiceTool software can be downloaded from the Retail System/BeoWise
section, and is updated several times a year. Always use the latest ServiceTool
version on you personal computer.
