I am thinking that there ought to be a listing here of hardware that uses each of these. I note the following pages and comments
> **[Choosing Digirig Model – digirig](https://digirig.net/choosing-digirig-model/)**
“If you are not familiar with your radio’s serial capabilities or do not know which port standard your radio uses then first [find the compatible transceiver cables](https://digirig.net/digirig-transceiver-compatibility/) and look for the configuration notes in the listing.”
I am thinking of a list that is separated into categories, some of which might be:
- radios that use the RS-232 version. For example, I have been using the RS-232 version with a variety of HTs. I wondered about my Icom T8A. It seems that “TTL” and “RS-232” apply only to the serial port, and the cable set has no programming cable, which implies either digirig is OK, because the serial port won’t be used. I am compiling a text note for myself, because there is no clear clue otherwise.
- radios that use the TTL version.
Here is partly why. I searched for a cable set for the Kenwood TS-570SG. No joy. On any variants. Ditto 570. I finally found
> **[Kenwood DB9 Digirig Cable Set – digirig](https://digirig.net/product/kenwood-cables-digirig-mobile/)**
which lists…[Kenwood TS-570](https://digirig.net/product-tag/kenwood-ts-570/), [Kenwood TS-570d](https://digirig.net/product-tag/kenwood-ts-570d/), [Kenwood TS-570DG](https://digirig.net/product-tag/kenwood-ts-570dg/), [Kenwood TS-570S](https://digirig.net/product-tag/kenwood-ts-570s/), [Kenwood TS-570SG](https://digirig.net/product-tag/kenwood-ts-570sg/), [Kenwood TS-590S](https://digirig.net/product-tag/kenwood-ts-590s/), [Kenwood TS-590SG](https://digirig.net/product-tag/kenwood-ts-590sg/),
edit 20260302a: Corrections: 1) I have been using the TTL version with my HTs, not the RS-232 version, but see my further notes. 2) I was seeking a cable for the Kenwood TS-590SG, not a 570 variant, but the comment applies. Searching on [digirig.net](http://digirig.net) and finding information is not always easy.
I started making notes to myself re the digirig hardware I have and how to use it, because we need to be sure not to mix TTL and RS-232 serial ports. Note especially the comments for the ICOM IC-T8A and Yaesu FT-70D. I have not yet tested the Lite with all my radios. I also have not tried programming the 480 or 590 with digirig. My notes follow:
Radio connections for digi comms and programming
digirig - TTL or RS-232 versions, Digirig Lite, USB isolator
> **[Understanding Rig Control Options – digirig](https://digirig.net/understanding-rig-control-options/)**
Baofeng HT - programming requires Digirig Mobile TTL
Kenwood TH-D72A
Kenwood TH-F6A
ICOM IC-T8A - either - no programming cable for the serial port
Yaesu FT-70D - either - no programming cable for the serial port
Kenwood TM-V71A - programming requires Digirig Mobile RS-232
- mini-DIN-6 1200 baud (DATA:audio/PTT)
- mini-DIN-6 9600 baud (DATA:audio/PTT) (menu change)
- mini-DIN-8 (PC) (20260302 cable doesn’t work with MCP-2A or chirp)
Kenwood TS-480SAT - CAT, programming requires Digirig Mobile RS-232
- mini-DIN-6 audio/PTT
- DB9 RS-232 for CAT, programming?
Kenwood TS-590SG - CAT, programming requires Digirig Mobile RS-232
- DIN-13 audio/PTT
- DB9 RS-232 for CAT, programming?

I hope you have better luck then me. I have not been able to get ptt to work with the ts-570s using wsjtx or flrig. I have tried suggestions like using c-media-A, ptt, vox, serial port set to use rts for ptt. There are even examples of people saying they use the CAT com port with rts using the same comport for PTT. I have read that pin 9 of the serial port is used to key the rig but I shouldnt need to mode the cable I purchased from digirig to work with the ts-570s.
If you find a solution, please share it with me.
Thanks,
Charles

Charles,
The PTT configuration depends on [model of Digirig](https://digirig.net/choosing-digirig-model/) you are using. Please refer to the PTT configuration section of the setup tutorial for specific model for details including PTT configuration examples:
Digirig Mobile: [https://digirig.net/getting-started-with-digirig-mobile/](https://digirig.net/getting-started-with-digirig-mobile/)
Digirig Lite: [https://digirig.net/digirig-lite-setup-manual/](https://digirig.net/digirig-lite-setup-manual/)
Digirig DR-891: [https://digirig.net/digirig-dr-891-setup-manual/](https://digirig.net/digirig-dr-891-setup-manual/)
For additional PTT troubleshooting steps including a simple way to simulate the PTT to test the cable and radio, please check out this video:
