K3 / N1MM & PTT footswitch for ESM

[W4RM]

I need a little help getting my K3 with footswitch plug into the back of the
K3  "PTT IN" to key the Enter Send Mode (ESM) in N1MM.  I'm assuming there
is a way that I can pass the footswitch closure through the K3 radio and
using LP Bridge into N1MM to act as if I hit "Enter" on the keyboard.

 

So far I have not luck in making it work.

 

Configuration

 

K3 on com 3 connected to computer

LP Bridge passing K3 to Comm 6 in N1MM (radio interface working)

CW keying is winkeyer usb on Comm 4 (Working)

N1mm set for ESM and that is working

 

But I can't figure out the setting to have the PTT from the footswitch in
the back of the radio make it into N1MM to key ESM.

 

Any help would be great!

 

Thanks

Bill,

The transmit/receive information will be sent to N1MM in response to an
IF command issued by N1MM or in response to a TQ command (again issued
by N1MM).  The TX.RX state is not included in the AI meta command (see
the K3 prorammer's reference).

You may have to ask the N1MM forum for additional information.  I am not
sure what commands are used when N1MM polls the K3/

Effectively you would be asking the K3 to control N1MM Logger's TX/RX
status. I'm quite sure you can't do this - the control goes the other
way (from N1MM Logger to the rig).

The normal way to set this up is to connect the footswitch to the
computer via a serial or parallel port interface, configure N1MM Logger
to use that serial or parallel port for footswitch input, and then set
up some form of PTT control from the Logger to the radio. The simplest
way for N1MM Logger to control PTT on the K3 with your equipment would
be simply to connect a cable between the WKUSB's PTT output and the K3's
PTT IN. N1MM Logger uses the WKUSB's PTT output in all modes, without
requiring any configuration other than that required for CW keying.
