[Elecraft] K3(s) SteppIR control

2020-05-19 Thread Andy Durbin 
"The information sent by the K3(s) is needed, hence the need to connect 
(somewhere) to TXD info from the K3(s). "

I suspect that signal name "TXD" may be being misused in this discussion.  
Having been caught by this I prefer to use the terms "data out" and "data in".

On a TS-590S COM port pin 2 is designated "RXD" and is the data output. COM 
port pin 3 is designated TXD" and is the data input.  I would expect K3 pin 
designations to be the same.

As has been pointed out - two RS-232 transmitters should not be connected 
together.  Multiple RS-232 receivers can usually be wired to one RS-232 
transmitter.  This is the scheme typically used in a "Y" cable.

Hi Lou,

The information sent by the K3(s) is needed, hence the need to connect
(somewhere) to TXD info from the K3(s). (could be at the P3 as well)
A separate CAT/logger program is not needed to invoke K3(s) info to be send

Using the K3(s) Auto Info setting in the Config menu assures that the K3(s)
sends frequency info each time the VFO is changed.
The SDA 100 follows this without a glitch.

Btw : I made a small .exe that invokes the K3(s) to send FA, FB and IF words
on a regular basis.
This could replace any (expensive or memory eating) logging program in case
you want to be absolutely sure all K3 frequency info is being send/decoded.
I use it for tracking purposes of my home made remote controlled PA, which
cannot afford to miss K3 info.
However it could be used with a K3/SDA100 combo as well.

The "official" SteppIR cable schematic also shows that Pin 3 (TXD out on the
K3S's RD232 DE9) is also to be connected.

Is that connection needed? If it is connected, might it obviate the
need for a separate CAT program?

If the SteppIR controller is connected in parallel with a computer
the TxD line *must not be* connected as it will load the TxD output
of the computer and *neither* device will be able to poll the
transceiver.

The appropriate schematic would be for the SteppIR "Y" cable:


Is that connection needed? If it is connected, might it obviate the 
need for a separate CAT program?

There are some (diode matrix or logic based) devices that will allow
two "controllers" to share a single RS-232 controlled device but they
are not easy to find/build.  An easier device (if your logger can
set DTR high when running) might be a simple relay to switch the TxD
line between computer and SteppIR depending on whether the logger is
running (and polling the transceiver).

I also have a K3s, P3, and Steppir SDA-100.  It took me some time to get it
working well, but it works quite well now.  See the inserted sketch 
  
I do have to have a CAT program operating in order for the SDA-100 to
autotrack, but it works well most (all?) that I have tried.  I mostly use
DXLab & N1MM.

Hi Andy,

You are right, that is the missing link.

I already took the SDA100 apart and found out the RS232 receiver MAX202 TTL
output was not going anywhere
Indeed it goes to an internal (open jumper), which also connects to pin 7
and 9.

Thanks for helping me out

[Elecraft] K3(s) SteppIR control

2020-05-16 Thread hdv 
Hi,

 

I want to control my SteppIR (SDA 100 controller) with my K3s.

I have a P3 as well, so can use the RS232 connection at the P3.

 

An RS-232 "sniffer" (or Y cable) has been made and works OK.

FA, FB and IF words coming from the K3s can been seen when I start Wintest
or my home-made FA/FB-generator.exe.

I can also decode those (frequency) words correctly with an Arduino (which
is used to slave an FT847 to the K3).

 

So the Y cable works OK and frequency information is present.

 

The Y cable is connected to the SDA 100 Data IN, radio port, points 2 (RXD)
and 5 (ground)

SDA 100 setting is : 

Mode :  Kenwood (in accordance with SteppIR instructions)

Din 19200

Dout 19200

 

Baud rate both P3 and Wintest = 19200

 

No Autotracking of the SteppIR occurs, changing baud rates makes no
difference.

 

The RS232 convertor inside the SDA100 works OK.

The MAX202 converts the data at RS232 level correctly to 0- 5V levels. 

 

I am a bit out of options. 

Anyone who can point me in the right direction?

 

73 Henk
