MAX485 USB DRIVER DOWNLOAD

Because of the distance between source of data and recipient of data, wireless data transfer is unsuitable for my application. The only mod I did was to install a ground wire running from the USB connector shield to the ground of the target circuitry. Sometimes you have to now when to give up. The RS line is typically terminated with ohms resistance on both ends of the line on short lines you might be able to live with termination on one end or even no termination sometimes. I found it is more rewarding to start with projects which have up to one unknown part, since that is something one can learn. How FTRL achieve that or does it have some pin for that purpose only? How would the wiring look like?

I suggest again to start with a simplex system, i. Use facts from multiple tutorials, to boost the confidence you have in the system. Actually, that is not the schematic of my sintech converter.

RS to PC using MAX issues

The circuit board was glued to the bottom on the case, so I could not easily look what is under it I expect that there is not anything interesting there worth to risk breaking mx485 device. MAX itself is short-circuit current limited and are protected against excessive power dissipation.

I selected this specifically because of the cheap price it is considerably cheaper than anything else I have seen for the same purpose.

Arduino Stack Exchange works best with JavaScript enabled. Faced with this undefined input, a ma485 might output the wrong logic state or worse yet, it might oscillate. The device promises to support bps baud rate and automatically detect the serial data rate signal.

Is it even feasible to get this working with the MAX and a usbrs converter? Sign up or log in Sign up using Google. According the data it should work on it. It has almost the same circuitry. Passive fail-safe biasing is accomplished through resistor networks of pull-up, termination, and pull-down resistors whose voltage divider action provide a differential dc bus voltage, VAB, when no driver is actively driving the bus.

I decided to download the driver directly from manufacturer. Thanks for the post. But I also feel that you feel a little uncomfortable with the project as it is. I am also attaching my code, which works fine when I use it through USB.

Note that Arduino is having write buffers, so it will be a little tricky to know exactly when to switch back udb listening after writing. OK, so I wrote the short sketch, and tested it.

Could this be my problem? August 26, at 9: Communication never allowed an internal delaycos missing bits or skip bits position.

How FTRL achieve that or does it have some pin for that purpose only? On the Arduino side, you can use the Serial1 or equal to write data out mad485 the MAX, which drives the wires. Of course it is not an RS, but comes at no further thinking.
