Funny N,

I know that PHONE wire used to be made from a special flexible wire that
was
wound in a way as to make it easy to bend, but still not fracture from
all that bending.
It was called "LITZ" wire.  It was sort of similar to flat wound guitar
strings.

Anyway, you might try "COONER WIRE" in California.   They have some very
flexible wire
that we use often.  They even have "LITZ" wire.  However, I don't know
for sure if they 
have any "CAT-3" or "PHONE" type cable.  But it wouldn't hurt to call
and ask.  
Or check out their website.. www.coonerwire.com.


	
Regards,

	
Jim

Subject: [PIC]Re: wanted ICD2 cable

Greeting Martin,
I checked with my engineer again for the RJ12 cables (used for ICD2 and
PICKit2), and found the cable we are currently using actually is CAT-3
communication cable, it differs a bit than the straight phone cable
since there are 3 sets of twisted pairs in the CAT-3 cable.  My
Microchip ICD2 cable has 6 straight wires. Not sure what kind of affect
the twisted pair will have for ICSP. It does appear working well though.


And according to Microchip, it would be better  for the cable length
less than 6  inches. (I actually tested a few 12-inches-long RJ12 cables
made from CAT-3 cables  and they appear working fine too.)

We are still looking for some good supplier for "stranded wire" cable
which are more flexible for use and manufacturing, but didn't find one
locally yet.

Greetings, Martin, It is good to hear that you got the package and
everything works. 
I personal don't think there is a particular reason to use solid wire
rather than stranded wire. They should both work with respect RJ12
connectors. 
The solid one does appear to be stiff comparing with the stranded wire. 
One more point is the conductor core size, the 24 AWG wire we are using
provides better conduct performance than 26 AWG wire, but again it
appears to be stiff when it is as short as about 6 inches.

I can confirm that the straight cable does indeed work for the ICD2. 
Funny, any reason why you used solid rather than stranded wire?
