KPC3 Setup
|
Last week I got my messaging question out of the way. Taking baby steps with this program. |

Bob,
That's a really big question - "how to hook up the KPC-3" you'll need to interface the KPC-3 with the computer via a serial cable into a traditional COM port, or... invest in a modern USB-to-Serial converter, which will then present a new COM port to the computer. You'll need to put the Kantronics into KISS mode. The way to do that is to connect to the Kantronics via hyperterminal (or a new program called PUTty) and place the Kantronics into KISS mode. The interface cable to the radio is very much radio-specific, but long story short you need to break-out the pin-out for the microphone and the speaker output and feed those back into the other port on the back of the Kantronics. finally, once you have the hardware setup, the APRS/32 software will need a new port set on KISS-Simply mode to talk to the KPC-3. (not the straight "KISS" mode.) That's a 30,000 foot overview. It will take much more steps to finalize. |

If the KPC3 is still hooked up from using UI-View, then nothing needs to change from a physical cabling perspective. The TNC would still connect to the radio the same way and also connect to the computer the same way. IMO the most straightforward way to use a Kantronics TNC with APRSIS32 is to change it to KISS mode and leave it that way. UI-View may have been putting the TNC in KISS mode and taking it out of KISS mode each time it started up and was shut down, which is different. I've been a bit dormant in APRS for a while now, so there are others on the list that will be better with the details on setting up an RF port using the "SimplyKISS" option, which is what you need to use. One fundamental thing when setting that up is APRSIS32 needs to know what com port you are using for the TNC. (The same com port that UI-View would have been configured to use) If setting the TNC in KISS mode more or less permanently is not an option, one alternative is to use an external script to put the TNC in KISS mode and also to take it out. I have posted scripts converted to .exe files for use in Windows that can be used for that purpose. Wow, they have been there for over 10 years now. It is also possible to configure APRSIS32 to take the TNC in and out of KISS mode, but I'll leave it to others to point you to the right wiki page for that - I think it is documented somewhere there. 73, Lee K5DAT On Sun, Oct 16, 2022 at 12:53 PM Bob Davet <davet354tfd@...> wrote:

All going through AGWpe as different ports (I assume). And connected to a radio with an optional internal TNC (EJ-41U or T3-135). I'd be interested in how you have the the TNCs connected? Any issues with PTT? Rob KB8RCO |

no sir have one radio one TNC kpcs 3 is set up as a Digi Standalone Digi and then audio comes from the speaker audio off the same radio on the digi to a sound card to a PC

It has RX and TX capability in "standard mode" to decode packets, determines whether to DIGI them, and acts on them accordingly? BUT ... it appears you are only using AGW as a decoder (radio speaker audio to sound card) with no computer audio to the radio mic. I think I got it now. Your APRSIS32 instance is receive only. APRSIS32 cannot send anything over RF. BTW, if you are using AGW with a sound card to decode audio tones into data and encodes data into audio tones, that "is" a TNC. And since each audio channel is "technically" a separate TNC, your stereo sound card with AGW could produce 2 TNCs, itself. Interesting configuration. Rob KB8RCO |
