The chips in adapters like that are usually powered by the PC. We measured the signals with an oscilloscope, which are sent to the device.

Any suggestions for an Win-based test tool? You should make some effort to differentiate between jitter within a given character which is bad and must be contained within limits vs jitter in the timing between characters, which any receiver ftdi usb to rs485 tolerate without upper limit.

A converter cable that is designed to easily connect peripheral devices, such as analogue and ISDN modems, digital cameras and hand held computers, which have a serial interface to a USB port. But a custom serial converter made from a USB micro would manage the ftdi usb to rs485 best.

The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, ftdi usb to rs485 for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering. FTDI is releasing the bus after each and every byte right after the stopbit via the TXEN port and ftdi usb to rs485 it immeditately again for the next byte which on fast machines is already in the buffer.

There are two possibilities as I see it.

Regarding your update, maybe a full speed vs high speed issue, but I don’t know. For the application connecting embedded ftid developed stuff to the PCit was not really time critical, just annoying about ftdi usb to rs485 uncertainty what might be the problem.

A likely suspect where the RS enable is concerned would be improper timing of that signal relative to the data, for example the data being disabled before the end of a character.

USB Serial Converter operates as a bridge between We suspected ftdi usb to rs485 there’s no internal clock ftdi usb to rs485 the adapter and the adapter uses a clock from the laptop, but FTDI support confirmed that the adapter has its own internal clock.

However, Ftdi usb to rs485 seems pretty unlikely to me. I will test that next week with an externally powered USB hub. Wish FTDI would give an option e. The application on the laptops is exactly the same and all drivers CDM 2. You could use a usb analyzer software or hardware to rule out software or driver issues. The communication is fairly simple, the computer sends periodic requests, the device answers them.
