Mysterious Contacts Besides The Battery

[thseiler]

Hi

If I open the Battery compartiment of my SL-C760, I can see 6 contacs, just beside the battery.
Does anyone know what these contacts are used for and what they have for a pinout ?

Thanks
Thomas

I think that's for the mysterious "JTAG" support, which is an industrial diagnostics standard.

I suspect that it isn't much use to home hobbyists.

I hoped it would be a kind of serial port (I thought that JTAG had 7 signals + GND, hasn't it ?)

Sigh, yes it isn't. A Serial Port OTOH would be...
I have just found about a bluetooth module supporting H4 (3,3volt level), fitting in the space between the white battery cover and the SL-c760 and, best its available in single quantities. To bad..

Anyway thanks for clarifiying this.

Hi everyone,

the contact pads are no secret i/o stuff, it's called
a checkpad and we know it since the SL-5000.

The JTAG interface is included via the SHARP I/O port:

 [ Invalid Attachment ]

The JTAG cable should be available via SHARP parts
service. The part # is : OIU-PLGWB9727

Both pictures taken from SHARPs technical documentation.
It's available under the part# 00ZSL5500SM/E . This is
the service manual for the SL-5500 series. I don't know
how it's in the US, here in Europe all tech information is
available for everyone (OK, you have to pay for it).

Hi Mr. Stephan

the contact pads are no secret i/o stuff, it's called
a checkpad and we know it since the SL-5000.

Ok, so these are only checkpads for the voltage regulators. Thanks for the info.
Do you think one can draw a few (~60) milliamps of power from these contacts ?

Best Regards
Thomas


BTW: Thank you for the nice repair work on my C760. Its like new !

How much for it? Maybe that help with writing 2.6 kernel for collie...

Hrw,
i don't know what they will charge for.
It's available online for free for SHARP service
dealers via the intranet.
Enduser source for documentations here in Germany is:

Lange oHG
Schaltungsdienst
Zehrensdorfer Straße 11

D   - 12277 Berlin
[a href=\"http://www.schaltungsdienst.de/gb/index.html]English homepage[/url]

Normally it's between 10-20 EUR.

@Thomas: Sorry, haven't noticed your question.
I wouldn't use these contacts to power anything.
We also don't have documentation about the
SL-C760, but experience shows that SHARP will
not make big changes if something established.
So we could expect that the pads will work like
in the previous models.
