[Elecraft] Pigknob

[Nick Garner]

Hi Brian,
I replied to your email a couple hours later, on Feb 1st at 15:02 PST.
 Perhaps it got filtered, there were quite a few emails in that thread and
the subject had [OT] in it.

Here are the relevant excerpts.
------
Original:
I'm trying to think of whether there would be any interaction with a K3
attached to LPBRIDGE.  The LPBRIDGE creates up to 5 virtual serial ports
and it essentially runs K3 the via the one real RS232 port.  It polls as
typically at 200 ms.  The virtual ports are use by a logging program, the
SKIMMER decoder/or ROCKY panadapter, and separate digital mode program(s).
 All must be run at the 38.4 baud rate.

I suppose, one would connect this device in the RS232 line.  Would there be
a problem with this?
------
Reply:
The question about where to put the knob; I imagine it could either go into
another serial port that LP Bridge manages or in-line.  If LP Bridge is
sending data that fast, there would be contention if the knob is interacted
with while LP Bridge was talking through the knob.
------

To add to that reply from back then, if the knob were connected in-line
with the computer and K3, as data comes into the knob from the computer, it
is immediately sent out the other port, byte for byte, unaltered.  The same
occurs in the other direction, from radio to computer.  If a button is
pushed on the knob, the entire text of that macro is immediately sent out
to the radio.  If LP Bridge can use another physical port, then you could
connect the Knob's rig port to a physical port on the computer and let LP
Bridge manage the communication from knob to radio.

Please let me know if you have any further questions.

73,
Nick
