[Elecraft] KRC2 Question

[Jack Brindle]

Let me try to explain. The KRC2 must be configured for BCD input by  
setting the W1-3 jumpers properly. The BCD data is fed into the BCD I/O  
pins from the computer or rig. The KRC2's MCU periodically checks this  
input, and when it sees something change, it outputs the proper relay  
information to the output drivers. It's really that simple.

While its in this mode, though, it pays no attention to the serial port  
or the auxbus. It is just "locked in" on the BCD input. Also, in any  
other band input mode, those pins are set for output, so you really do  
have to set the configuration jumpers.

And lastly, there is a bug in the V1.0 code that prevents this form  
operating properly. V1.1 should be out within a couple of weeks, so if  
you have been trying to use this mode and it doesn't work right, help  
is very near!

If you have any other questions, just ask.
