[Elecraft] K3 Cabling Questions

[Dick Dievendorff]

The K3 Owner's manual describes the accessory connector pinout.  See page
18.

I found a picture of the connector, with a picture of the pin layout, on
Wikipedia.  I confess that I often am confused by pin layout pictures,
because it matters whether you're looking into the connector or looking from
behind where the wires are fastened. It's easy to get backwards.

When my TTD Band Decoder arrives, I plan to run multiple cables into the K3
accessory connector, and introduce a molex connector into the band decoder
cable to make it easy to disconnect.  If I ever change the band decoder
cable length, there may eventually be two molex connectors in that path.

The DE-15 accessory connector and the 9-pin RS-232 connector on the back of
the K3 are both female.

The RJ-45 connector on the bottom of the K3 is used to connect an In Circuit
Debugger (ICD) used by Elecraft for microcontroller development and
diagnostic purposes.

Subject: [Elecraft] K3 Cabling Questions

While I await delivery of my K3 I want to make some cables for FSK 
keying and my Top Ten Band Decoder.  Does anyone have a schematic for 
these cables?  Since multiple functions are handled by the ACC 
connector, would it be advisable to use a junction box, or just run 
multiple cables into the ACC connector?

Are the RS-232 and ACC connectors on the back of the K3 both female?

One other question:  what is the RJ-45 connector on the bottom of the 
K3 used for?


Thanks,
John N3AM
