[Elecraft] AUX I/O connector

[Thomas Norff]

Hi Knut, 

in the current owners manual there is a short information about
CONFIG:DIGOUT... which is not visible on my K3...
maybe in the next MCU revision

----
DIGOUT 1

DIGOUT1 is a general-purpose open-drain output
controlled by the CONFIG:DIGOUT1 menu entry.
It can be controlled from a computer; refer to the
K3 Programmer's Reference. A 220-ohm series
resistor is included to protect the output driver.
----
Transverter Control

Also, with KIO3 = TRNS or HF-TRNS, the
DIGOUT0 line (AUX I/O, pin 6) will output 0 V
when low power mode is selected for the current
transverter band (CONFIG:XVn PWR). At all
other times, DIGOUT0 will be floating (Hi-Z).
---
Config-Menu

DIGOUT{n}
Directly controls two general-purpose digital output lines on the AUX I/O
connector. {n} = 0 or 1. Tap 1 to alternate between the two. These are
TTL-level
signals with a nominal output voltage of 0 V (LO) or 5 V (HI). Recommended
max. load is 15 mA (enough to power one LED, for example).

Hi all,

Is there a current or planned use for the signals DIGOUT0 and DIGOUT1 on the
AUX connector? I did a search of the archives for DIGOUT and found nothing.
I have a need for a pulse to trigger an auto tuner when using the TUNE
button and one of these would seem a good candidate.
