Rear I/O and remote button
« on: 2009-11-15, 19:40:43 »
Hello Mike, I think is really possibile to use the rear I/O port to 'short' a remote button. Maybe with the same OPTO coupler for PC CW Keying? The idea is to 'remote push' the TUNE button on my MFJ automatic tuner.
To be checked, not sure, but I think when I push TUNE, the button is grounded.

Hi

If you do not need the CW-keyer you can use the I/O:s for what ever you want. Set CW-keyer enable to 0.
The the I/O is transfered between the boxes.  see http://www.remotrig.com/bilder/generic-CW-cable-I5b.pdf

pin 1 is transfered to pin 3 and pin 2 to pin 6, there are FVD301.s on the outputs witch kan sink 200mA

Thanks! Connected to the rear panel 'radio interface' connector (stereo jack 3.5") on my MFJ-993B automatic tuner  ;)
