External Keying Auto-Detect problem

[n6wg]

I finally got my problems with N1MM Logger sorted out, only to find
that my keying adapter doesn't produce the expected results.

I have a pair of 1N4148 silicon diodes going from the Logger key line
to each of the dit and dah lines to the K2.  The cathode of each diode
goes to the common Logger keying line.  My paddles connect
directly to the dit and dah lines for paddle keying.  The K2 is set to
InP PdLn and works fine with the paddles.  If I put a closure on the
keying line from Logger, though, I get a continuous di-da-di-da-di-da-di.

If I set the K2 input to handkey, and connect the Logger key line directly,
it works just fine.

The K2 is suposed to detect simultaneous closures on the dit and dah lines,
and interpret that as a hand key input.  Not doing it so far.
When I turn on the K2, the firmware versions displayed are 2.03d and 1.07.

Anyone have any ideas on how to get this working?  Should I be using
Germanium diodes instead?

Bob:

Select ->  Menu, InP - then - PdLn,  Now tap DISPLAY.  You should briefly
see " AdEt " and either OFF or On.

Select On. Then exit the menu (tap any other key.

Well, the mystery is solved.
I had not realized there was an on/off menu choice for the
auto-detect function.  Two hams told me about it, and yes,
it did the trick.  Now in business, and I can get back to
trying to learn N1MM Logger.

Ken:

It is kind of tricky to get it right.  The actions you describe indicate
that you have the underline under the InP. The underline can not be under
the InP to get this extra feature.  

Follow these steps:

Tap Menu

Then Select (that is, rotate the VFO as needed) - InP  PdLn - (or it may
read PdLr or HAnd),

Depress (HOLD) MENU so that PdLn (or it may read PdLr or HAnd) is underlined
(or if you use reverse paddle that PdLr is underlined. Don't leave it in
Hand as this is pure Straight Key. If it reads HAnd rotate the VFO to PdLn
or PdLr.)  The underline can not be under the InP!!!!

Now tap DISPLAY.  You should briefly see " AdEt " and either OFF or On.

Tap DISPLAY again if you need to so that the last display you saw is AdEt
On. (It toggles each time you tap DISPLAY.)

Then exit the menu (tap Menu key).

I have found that sometimes I need to shut off "auto-detect" as I squeeze
the two paddles together at exactly the same time and thus get a long dah
rather than di dah di dah di dah.

Rich,
Mine says  Pdln  DISPLAY  
response  is  SEC
Port OFF

One problem I have noticed is no keying on insertion of the
Bencher paddle key line cable.   I have to play around with it
before I get any keying.  Is this related?
