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. |

QUOTE(kahm @ Apr 25 2005, 04:30 PM) I think that's for the mysterious "JTAG" support, which is an industrial diagnostics standard. I hoped it would be a kind of serial port (I thought that JTAG had 7 signals + GND, hasn't it ?) QUOTE I suspect that it isn't much use to home hobbyists. 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. Thomas |

Hi everyone,
the contact pads are no secret i/o stuff, it's called a checkpad and we know it since the SL-5000. 
checkpad.bmp ( 25.84K )
Number of downloads: 250The JTAG interface is included via the SHARP I/O port:
jtag.bmp ( 19.79K )
Number of downloads: 202The 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). ///TRIsoft Marc Stephan |

Hi Mr. Stephan
QUOTE(TRIsoft @ Apr 25 2005, 07:52 PM) 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 ! |

QUOTE(Hrw @ May 5 2005, 09:33 PM) 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 English homepage 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. ///TRIsoft Marc Stephan |
