Which cables?

[Benson-2]

I don't have a K3 yet but am trying to get some accessories together beforehand. My computer has a (male) serial port. Do I need to get a cable like this one:

"This is fully shielded, straight-through Serial cable. It has molded DB9 male to female connectors."

For the sound card connection - two shielded cables with 1/8" plugs on each end?

Benson, K4GST

Benson,

 

Be sure the male plug (the one attaching to the K3) has fastening bolts and not threaded studs.

And it's a straight-through instead of a null-modem, right?

Sounds good. Yes, you want straight-through.

Yep. I use stereo cables in both directions. A mono plug in a stereo
socket would short the "ring" to ground", which may or may not do harm.

No. You can build a better one using ordinary CAT5 and two DB9
connectors. Because CAT5 is twisted pair, it provides much better
noise and RF immunity than cables that are not twisted pairs.
Twisting is FAR more important in noise/RF rejection than cable
shielding.
