[Elecraft] Can I split or share my ACC port?

[Matthew Zilmer]

RS232 is an end-to-end interface, not a multipdrop.  That's just the Physical Layer, but more than one device driving will cause contention.

Subject: [Elecraft] Can I split or share my ACC port?

I spend a lot of my time connecting and disconnecting accessories from the back of my K3 and I find this tedious.

In my shack I have a, Expert 1K linear amp and a Microkeyer II which both like to use the ACC Port on the K3 I use a Remote-rig unit to control the
K3 when I am away and this too needs the ACC.

Instead of connecting one of these items at a time, is it OK to use a VGA cable splitter and have both or three connected simultaneously?
Is this port a strictly one-at-a-time guy?

In addition to the issue with the ACC port, the accessories above (+ add to this a Signalink USB) I find that I am regularly having to change the plugs
into  my:   Line-in , line-out, Paddle, Key, PTT and Speakers sockets and
RS232 port.

Which of these 'ports' can be shared or split and which will will only safely take one I/O?

I am tempted to build an external 'Patch Box' to give me handier and easier access to the K3 back-panel .

Has anyone built one of these or is it even necessary if the ports can be split and permanently shared?

I believe that Y cables are available for the RS232 on the K3.
Into how many RS232's can these be split?
 2...3....4?
I have an Expert-1K, a CAT, and a Steppir controller and a Remote-rig - all of which would like a place on the nipple!

Thanks  and GB
