S7 200 Cn Programming Cable

[Vernon]

Outof curiosity I wanted to test if my Baofeng UV-5R programming cable was compatible with my new KG-935G. I am very happy to report that indeed it is compatible with the KG-935G. I have confirmed that it communicates flawlessly with the KG935 and the horrid Wouxun software. I am not sure if this has already been discussed here, but I wanted to help others save some $$ on buying an expensive programming cable from BTWR. $50 is a bit steep for a simple USB cable! An $11 cable works as good as a $50 cable. Sorry, not sorry, BTWR.

I simply plugged it into a USB port. Set the COM Port to COM1. Ran the Wouxun programming software (Yuck!). Connected the radio to cable. And, viola! No special sorcery or VooDoo magic to get this thing to work. If anyone has any issues getting their radio to connect to their PC let me know. I'll be happy to help you out.

My experience is that this cable is MUCH better than the typical Baofeng one, and I use it for all my radios that require that type of cable now. No driver games, and I have one radio that would transmit when you plugged in a cheap cable; no such issues with the Wouxun one.

RT Systems software requires that you use the corresponding RT Systems cable. The item on the BTWR site is a bundle with both cable and software. But the cable can be used with multiple different radios that use the Kenwood interface, so you buy the cable once and then just buy the software if you want to program other radios that use the same cable.

Their software packages are great. Often easier to use than the manufacturer's software (if there IS any) and Just Works. When you get right down to it, analog radio programming software looks like a spreadsheet with another page where you can set options on the radio. So there is nothing fancy about their software; it just works and isn't full of bugs.

FWIW, i have also had about 5 of those $11 amazon cables and they either didnt work at all, or stopped working after a few months... The extra $5 for a cable that is virtually guaranteed to work from BTWR is well worth it.. No voodoo or anything required on Windows or Mac.. just plug it in and it works.. Unlike your $11 junk cables.

My junk cable was plug and play and no trouble to use at all. I've been using my one and only programming cable for over over a year without any trouble. I'll keep my junk cable, which works perfectly fine for it's intended purpose, and my extra cash in my wallet for future GMRS radio and equipment purchases.

Roger that. I'm a complete novice when it comes to GMRS. Being not aware that the software and cable bundle can be used for other radios was my misunderstanding. But, still trying to help others save cash if all they have are 1 or 2 radios.

Yah, that is a 3rd-party cable and software package - the 3rd party charges more, thats why BTWR charges more for this option. Most people buy the $15 cable from BTWR, use the free software that comes with the radio, and call it a day..

Roger that! Note taken and your advice is appreciated. Time will tell how long this cable will hold up. I will order the $15 cable tomorrow and keep it in my "Go Kit" as a fail safe backup. I have lots to learn

Chiming in on the cables. I purchased the RT Systems cables when I purchased their software. I am able to use their cables with the Wouxun software and the RT Systems software. I have cables with the Kenwood-compatible connector for the HTs, and one with the RJ45 for use with the KG-1000G. So now the Wouxun cable stay in storage and I am only using the RT Systems cables.

*This same cable works find with my subsequent additions of the Pofung P15UV (a Radioddity GM-30 clone) and the ham radio version, the TYT-UV88 (both using Windows software the UV88 can also work in CHIRP)

The point about these cables that hasn't been made clear is: there are a lot of different cables for different radios with different programming or mic/speaker sockets. The most common is the two-pin "Kenwood K-1" style used by most Baofeng (not all) and many other brands. Yes, a good FTDI K-1 cable is about $15.

The price you are quoting is for the proprietary (but outstanding) software produced by RT Systems, AND their software, in a bundle. Their cables supposedly had some sort of special wiring or chip inside that was required to use with their software (a form of piracy protection). However, once you buy a bundle, you can use that same cable with another compatible radio and just buy their software for less money. They are a small, USA-based company that writes and supports their software, unlike the terrible software that comes with CCRs.

Since most rigs have a separate Tx and Rx pin I simply jumper these together for my Anytone cable. Anytone have probably discovered how to set Tx to high-impedance when receiving. However they do it, that cable works fine both receiving data from the rig and changing and updating it.

I bought a Quansheng UV-K5(8), and I am impressed by the audio quality, there appears to be a better ratio of signal to noise out of the speaker on listening, and it's a nice little radio, though with some quirks.

I also bought a Baofeng programming cable that is promised will work with the Quansheng UV-K5, which is in every sense the same as my Quansheng UV-K5(8). This is a Kenwood style programming cable, not to be confused with the USB-C cable which only charges the radio.

On both systems, plugging in the cable finds the USB-to-Serial chip and creates the serial port, but there is no possibility of connecting to the Quansheng, I tried for hours on both systems, trying Chirp, generic drivers, hideous Quansheng USB drivers that only work if you set your Windows display language to Simplified Chinese, Quansheng provided firmware flash tool (Just to try to get something to connect) but it is impossible to connect the Quansheng radio on either system.

The serial port settings (Buad, parity, stop bit, etc) are different for the Baofeng that works and the Quansheng that doesn't, but nobody on the internet seems to have documented this, so it's unlikely.

I wish I had stumbled upon this thread sooner. I spent almost 2 days struggling with my radio and cable, but I finally figured that the cable was not inserted properly. I gripped the cable as hard as I could against the side of the case, it took several tries, the best I could do was 76%. Then it finally worked! I completely believed I had bricked the radio for 2 days and I was elated when it finally worked. I ordered 2 new cables and once they are verified I will gladly toss the bad cable. 73 to all.

My first post here and until a couple of days ago I had no idea anything called unitronics existed but we ( the company) bought a used machine with one of those things in them and I have to modify the program so I need to connect to the unit. Is it possible to make cable up? Anyone knows the pint out from last say an RJ45 to the D9 in the unit? Is it just staring wiring thing and if yes why the commercially sold cable has a dongle?

I don't think I downloaded visiologic as I have no idea what it is. I have only one unitronics unit that I wanted to modify and from the reading I did I downloaded the software I needed which was U90 ladder ad download manager which caused havoc on my PC and deleted EVERY windows restore points I had before installing the software. I uninstalled them and will put them on an old computer that I can risk getting destroyed by their software.

1). The diagrams you need are in the U90 help files, open help and do a search for "Direct Communication". The 7th listing down is Direct Communications- PC to PLC and open that and you're there. It has everything you need.

3). I do not know your computer, but I have never had any programs from Unitronics delete restore points. What Windows version are you using? W10 has the most annoying habit of changing all the user preferences back to what Msoft want during certain updating. In amongst this it also turns off System Restore, thus deleting all points. Perhaps this has happened to you and you have only just found out that Sys Restore is off because you haven't looked at it for a while, thinking it was running ok when in fact it wasn't.

The software pretty much destroyed my laptop with win7 ultimate with tons of automation software on it. One error message started right after installing unitronics and I went to restore to previous point and realized all my resotre points which I created personally have been deleted and found only two unitronics restore points.
