K3(s) SteppIR control
Locked
 
|
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 PA0C -- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. https://www.avast.com/antivirus ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

"The Y cable is connected to the SDA 100 Data IN, radio port, points 2 (RXD) and 5 (ground)"
You also need to link 7 and 9 on the SDA 100 connector. Pin assignments on the SDA 100 connector are not typical RS-232. "PINOUT of 9 pin SUBD DATA IN CONNECTOR 1. Data out RXD 2. RXD to RS232 Radio TXD 3. TXD to Radio RXD 4. TTL Kenwood and active high for Radio CTS 5. Signal Ground 6. 7. TTL version of pin 2 8. NC 9. TTL RXD for Steppir."

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.

Henk:
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 <http://elecraft.365791.n2.nabble.com/file/t394485/K3s_Configuration-B.jpg> 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. 73, Rob - AE7AP -- Sent from: http://elecraft.365791.n2.nabble.com/ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

The "official" SteppIR cable schematic also shows that Pin 3 (TXD out on the
K3S's RD232 DE9) is also to be connected. https://groups.io/g/steppir/files/Controller%20Cable%20Schematics/S-26_21-6026-01%20Cable,%209%20pin%20FM%20to%20Male%202%203%205.pdf Is that connection needed? If it is connected, might it obviate the need for a separate CAT program? 73, Lou, W0FK ANDY DURBIN wrote > "The Y cable is connected to the SDA 100 Data IN, radio port, points 2 > (RXD) and 5 (ground)" > > You also need to link 7 and 9 on the SDA 100 connector.

> 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: <https://groups.io/g/steppir/files/Controller%20Cable%20Schematics/Y_cable.pdf> > 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). 73, ...

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. 73 Henk PA0C -----Oorspronkelijk bericht----- Van: [hidden email] <[hidden email]> Namens Lou W0FK Verzonden: dinsdag 19 mei 2020 15:21 Aan: [hidden email] Onderwerp: Re: [Elecraft] K3(s) SteppIR control The "official" SteppIR cable schematic also shows that Pin 3 (TXD out on the K3S's RD232 DE9) is also to be connected. https://groups.io/g/steppir/files/Controller%20Cable%20Schematics/S-26_21-60 26-01%20Cable,%209%20pin%20FM%20to%20Male%202%203%205.pdf Is that connection needed?

"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. 73, Andy, k3wyc ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |
