[Elecraft] Keypad - Button Box

[Richard Gillingham]

I have the 681 35 key serial keypad, but in addition to using it alone I also use my logger/rig control through the same port using VSPE software.  Works well.  With VSPE you can have as many hardware/software apps interfacing with the KX3 as you may need.  I suppose you can overload the VSPE, but I haven’t yet.  I also got the lead on this from Jean-Francois.  Many thanks to him for his advise..

While all the above statements may be true here is my experience... but with a KX3 mind you! 
  
I have the model 684 serial 24 key keypad. It is connected to my KX3 through a "Y" connection to the serial port on the KX3 (ACC1 if I recall correctly). After programming, it has no connection to the computer. I ran the programmer program and programmed the keypad on a WIN 7 OS computer and had no problems other than learning the macro commands and the KX3 variants. There are no data conflicts as the keypad only sends and the other serial device on ACC1 only listens.  
  
As an example, if I want to change from PSK31 on 14.070.000 USB at 1.0 watts (to drive my HR-50 at 25 wts) to SSB on 40 meters at 10 watts and set the filter to 2.5kHz I push one button. I have keys set up for various filter widths, band and mode changes, etc. Works for me. Programmer also comes with a drawing file that lets you design and print your own key cap legends. 
  
I first heard or saw this keypad a year or so ago when Jean-Francois Menard, VA2SS, posted his project. He used the 35 key version. He later published the project particulars in an article in QST I believe. He and several others were very helpful with macro issues and building the serial cable with the KX3 plug on one end. Turns out I was trying to use a damaged length of cable.
