[WT-support] Trigger Icom IC-7000 DVK from WinTest

The hardware from the parallel port is actually easy but as you say parallel ports are becoming a thing of the past.


If there are any software engineers out there that fancy tweaking the drivers here, then the solution would be easy.




A custom DLL with specific calls could be made (emulate Kenwood or Yaesu) and in DXX mode you can toggle up to 8 x I/O ports on say the FT232 USB bridge device.


I have never known it to be able to bit bash and do VCP mode. If that was possible it would appear just as another interface in the radio configuration.


Yip, they are intended to be USB<>Serial bridges but can also be put into I/O only mode and used for bit bashing as just IO or I2C or JTAG or….


4 or 5 Optos grounding or shorting the series resistors in the Icom network wired to the mic jack as an external keypad would allow control. 


It would also be isolated and USB so portable even onto laptops

To the best of my knowledge, the Icom Digital Voice Recorder, which can also be used as a Voice Keyer, cannot be controlled by any software at this time, not even Icom's.  If anyone discovers otherwise, please let us know.


The published Icom software command set does not list any voice keyer playback or recording commands.  I am 99% certain that this applies to all Icom radios, not just the IC-7000.


In contrast, the following radios fully support voice keyer playback from software:

1.	Elecraft K3 (with KDVR3 option)
2.	Kenwood TS-590s, TS-990s, TS-2000
3.	Yaesu FT-2000, FT-5000

See http://bit.ly/wtscripts for the Win-Test scripts I've written to control the voice keyers of the radios listed above.


I am hopeful that Icom will eventually offer a firmware enhancement that will allow their voice keyer hardware to be controlled by PC software.  Until that time, there is nothing else you can do other than build your hardware interface that accept's Win-Test's legacy  <http://docs.win-test.com/wiki/Interfaces#Digital_Voice_Keyer> "External Voice Keyer" control on the LPT port pins (if you have a computer with an LPT port), and translates these LPT signals into one of the four resistance values (1.5, 3, 5.2, and 9.9 K ohms) that are required by Icom.  See the Icom External Keypad circuit in the Icom manual.


Maybe there's a hardware engineer reading this list who can build a prototype and share the design.  Too bad it's so difficult to buy computers with LPT ports these days (USB-to-LPT adapters probably will not work).

Does an IC7000 have a DVK?  I don't think it does.
