ACO CDN-USB Intercom Cable Diagram: Identifying GND, RX, TX, and + for Programming Compatibility

Question

Hello. I have a question for dear colleagues who are experts in electronic subjects, namely if someone has a cable diagram as in the subject, or maybe someone has one and can throw some photos what it looks like inside? link to the manufacturer's website with a cable I suppose it is a...

C use a voltmeter to determine where GND and where the power is. Then, GND and two unknowns connected to the intercom. Turn on the intercom power supply. If the program does not work, swap the two unknown wires.

this cable is not only an electric signal dissipation but also a converter supporting ftdi, couplers, if you count it all - it's probably the amount of 60-80 PLN for the ready one is reasonable

Especially that FTDI on the universal is not easy to solder (e.g. FT230XS).

lehastar · Answer

If up to PLN 100 is not worth the trouble ..

If you have the appropriate PCB and equipment for free (e.g. in a drawer), time is worth it. Sometimes you can adapt something you have. I personally would make such a cable quickly. I have various FTDI projects (as long as such a converter is sitting there and a specific type is required). You just need to force the CPU to reset permanently, a few wires, and you're done. It's just that this is a temporary solution, if it were to be a permanent interface, the cost of the PCB makes such a job unprofitable.

The Lord is absolutely right. Joke - I once made an RS-232 converter into RS-485

IGS · Answer

beautiful spider - it is important that it worked however, I wrote back what I wrote back not accidentally, the author assumed that he is dealing with a simple converter ... most of us here are electronics and can do something, sometimes like, sometimes must - but in this case I preferred to make the author aware, it would be cheaper than wasting time to buy a ready-made product with plugs, housing ...

My not that good, but it worked too. Somewhere I saw a photo 68 or 84 PLCC soldered in place of the TQFP chip.

Hello.
The cable was bought from the manufacturer, it works as it should, so ok, but I took it apart anyway to see what's sitting there, hehe. so this is the FTDI 1549-C chip and the smaller 54TI JBR, the cable after connecting to the computer is identified as "ACO CDN" later, after installing the controls, it is as "USB SERIAL CONVERTER" software for managing the interphone exchange, after starting it detects the connected cable and you can work, I tried on a different usb rs converter but the program did not detect it, maybe there is something programmed in the FTDI chip so the program knows that the cable is the right one.
That's it for your message, thanks for your interest in the topic.

best regards.

Change the VID and PID in another cable (as possible) and it will probably work unless the software is referenced by D2XX libraries. Added after 1 [minutes]: Did you read the symbols wrong? There is no FTDI 1549-C. I read from the photo that it was FT232RL.

tanya03 · Answer

Hello.
Of course you are right, the offer to all this misread is actually FT232RL, sorry for the error.
In the second case, you are also right, the application communicates via FTD2XX.dll without it, the program does not start, on another adapter it does not work regardless of the replacement of the wires.

IGS · Answer

without a cable with a converter, the program works, but in the offline mode

tanya03 · Answer

Yes, you are right, I did not express myself precisely when I wrote that it does not work, I mean that it is impossible to make changes in the headquarters, i.e. that there is no communication between the management program and the headquarters, and not that the computer program itself does not work.

lehastar · Answer

A very beautiful sight. Sorry about the offtop. I want to entertain my friends: About the topic - I made a simple software protection key based on FT232RL. The program checks the MD5 programmed in the FT232RL EEPROM based on the serial number.

Anonymous · Answer

In fact, simple because the serial number can be generated any. What's more, using FT22x, FT201, FT200, FT232H you can simulate other FTDI systems. As for the serial number, I had a different task. Generate it from the microcontroller level. It even works.

Mikrob · Answer

Has anyone tried to use other USB converters that are on sale for programming, e.g. atmega?

vogelek1 · Answer

Question and how do the wires come out on the other side of the cable from this purchased ftdi usb module? can you send a photo of this other end?
