'[PIC]Re: Allowable ICD length'

FWIW, this is what Microchip has to say about the ICD cable length.  I
thought I would just pass this along to the rest of the list.

"Regarding the cable length, I'm assuming that you're talking about the
little RJ45 cable that looks like a phone cable.  Is that correct?  If so,
this is a serial interface to the ICD header and shouldn't be extended
much beyond the cable length provided (8-9 inches).  This is unshielded,
six wire conductor and longer lengths could generate noise damaging to the
protocol.  This is the only cable length that we've tested."

Regards,
Ed

To lengthen the cable, I would be very tempted to use the twisted pair Cat 5
cable that is used for computer network connections. This would hopefully get
you around many of the noise problems.

I have built my own ICD and use the below mentioned cable with a length of 4
meters with no problems
