KAT500 advice needed

[H A Layer]

Hooray--just received noticed of the KAT500-K ready to ship. (Order
dated May 18). This will be my first experience with an ATU, so I would
appreciate advice.

My rig consists of the FLEX-3000 transceiver and a KPA500 linear.  I
only operate SSB or AM. The T/R is a simple rotary 2P3T switch connected
to both PTT lines
that allows three operating modes: Pos 1: Receive Only, Pos 2: Transmit
with Flex only, Pos 3: Transmit with Flex and KPA500. Since the switch
is rotary,
when I return to receive, it turns off the KPA500 before switching the
FLEX to receive.  I know this T/R is primitive, but I am paranoid about
blowing up
the FLEX with any RF "residue" from the linear.  The delay is probably a
solid half-second or more, so I sleep better at night!

I hope I can maintain this simple T/R setup with the addition of the
KAT500.

Also, Elecraft asked me, "...Please note that we have released the
Optional KAT500 to KPA500 Cable, E850463, for $24.95. Let me know if you
would
like this added to your order. Your Kat500 will come with a KXUSB cable
standard. If you would rather have the KXSER cable please let me know."

Are they offering two optional cables: E850463 and KXSER? I assume since
I will not be using the K3, that the standard KXUSB cable is
all I need --but I am not sure.  Help!

You'll just take the RCA keying cable that's currently plugged into
your KPA500 and move it to the "guzinta" on the KAT500, and run
another cable from the "guzouta" to the KPA500.

That's correct... or, if you have an existing RS232 port on your
computer, and prefer to use that instead of USB, you can request a
KXSER instead of the KXUSB.
