    A way to delay UART frame for approx. 200-300us.

    yes, here you are right on all counts. Next time just refrain from something writing and let to answer other members which are less tired than you or so. :laugh: I would be much obliged. Cheers

    You must not assume anything. If I were you I wouldn't jump to conclusions. :thumbsdown:

    it's not clear what did you mean by clock. Is there a specialized IC?

    A way to delay UART frame for approx. 200-300us.

    Klaus, could you just out of curiosity draw a sketch, how it would look like: the clock + MC14517, input, output and so forth.

    A way to delay UART frame for approx. 200-300us.

    Let's start with 9600 and it would be nice if it would be still working at 19200. BR

    A way to delay UART frame for approx. 200-300us.

    Hello everyone, I'm figuring out a way to delay UART frame for approx. 200-300us. Are there ways to do that? Could anyone suggest something on this matter? BR

    MAX485 modifications. Need help to find out what does it mean.

    it appears to be T = tape. The package standard. The tape winds around a reel. Further, to positioner at soldering automat. It has nothing to do with electronic features of IC. :bang: It uses when you need to solder thousand chips/components a day, for example. :-) Thanks to all!

    MAX485 modifications. Need help to find out what does it mean.

    Hello everyone, I've noticed that MAX485CSA appeared on the market with additional characters situated just after CSA. Like MAX485CSA+, MAX485CSA+T CSA -it's clear from MAX485 manual. That means SO8, 0..+70; https://datasheets.maximintegrated.com/en/ds/MAX1487-MAX491.pdf I've tried to find...

    UART-->RS485 (transmission is finished and it may respond)

    The master really doesn't know any protocols, except mentioned above the most common ASC protocol. That's fully in line what I have in practice, on the bench. May I ask, you figured that out based on #16? I gave some additional info there. BR

    UART-->RS485 (transmission is finished and it may respond)

    Acynchronous Serial Communication is called (in the same WIKI) as a most common protocol in use. Lets see here: https://en.wikipedia.org/wiki/RS-485 BR

    UART-->RS485 (transmission is finished and it may respond)

    OK, then it's usual acynchronous serial protocol. Default: 9600 baud rate, 8 data bits, even parity, 1 start, 1 stop bit.

    UART-->RS485 (transmission is finished and it may respond)

    As I wrote above, the Master is set to so-called 'transparent' protocol. The Slave doesn't know any known industrial protocols like Modbus, etc. The slave just executes commands which are programmed in its firmware. RS485 half-duplex Master's hardware is unknown, the Slave uses MAX485. Still...

    UART-->RS485 (transmission is finished and it may respond)

    Re: UART-->RS485 (transmission is finished and it may respond) Bingo! You are right. I think I have to purchase an oscilloscope (it is final straw).:-) This is a new install. Consider that as an experiment within a project. Well, Half-Duplex variant. the green one is received...

    UART-->RS485 (transmission is finished and it may respond)

    I'm afraid, you are wrong. Many industrial devices communicate with each other and they are even not aware, that there are protocols at all, especially industrial. Firmware --> UART-->RS485. Well, the Master is set to so-called 'transparent' protocol. Have you ever heard about this protocol...

    UART-->RS485 (transmission is finished and it may respond)

    Re: UART-->RS485 (transmission is finished and it may respond) Hello everyone, Roughly, it may say that getting of distorted, unreadable Chars, as a variant of course, is a result of some kind of cutting, either it is start bit or stop bit, while transmission phase. Worse yet, it may be...
