Reccomended KXV3 wiring

Phil Salas
You can buy SVGA Y-Adapter cables very inexpensively (SVGA is the DIN15HD
connector).  I found them at my local Fry's Electronics.  I see they are
also on eBay.

Be careful.  Most VGA cables are missing wire connections to various
pins.  For example pins 4 and 11 are almost always missing.  Pin 9
sometimes. I have one cable that has only 9 wires.  These are not
unimportant pins to many of us.  The fact that all pins are sometimes
present in the connector, doesn't mean the wires are there.

Check out any cable you get with an ohmmeter to make sure the lines you
want are present.

There are many ground return connections in the standard SVGA pinout, so
some of those "wires" may actually be shields. They might also be
connected together.

This is looking less and less like a good idea...

The SVGA Y-adapter I found at Fry's Electronics had all 15 pins wired straight across.  MAybe I was just lucky.

Hi

I don't think a 15 pin Y adapter is going to be useful in connecting a
transverter unless you are also connecting some other peripherals like a PA
or band decoder that require I/O pins in the 15 pin connector in addition to
the 4 pins required for the transverters.

If you are thinking of using the Y adapter to connect several transverters
then you will still need to make up 15 to 9 pin adapters with the proper
pins connected for the transverters. The simplest solution id to make up a 4
wire cable with one 15 pin connector for the K3 and one or more 9 pin
connectors for each transverter daisy chained.

The cable details are shown in the transverter manual for a K2. For the K3
the 9 pin connector is replaced with a 15 pin D type connector and is wired
as described in the K3 manual

In addition, each XVTR kit comes with it's own 9 pin connector/cable and wiring
instructions for single or daisy chained use.
