Here are ebay's listings of USB to RS converters - well worth looking at to see the range available and prices. You won't build one for that little - probably by a factor of 10 to 20!

Here are a few dozen photos and links to serial to USB converers - hover over the pictures for more information on the page linked to above - not on the picture below - click to go to the related site. A few examples - lots of choice!!! You can build your own using any of several available custom ICs created for this purpose - but doing that will cost you more than buying a prebuilt one.

The how to remove paint from blue jeans common units usually a "cable" that plugs into a USB port appear to a PC as a standard serial "comms port".

They work across a range of baud rates. May be manufacturer dependant. Will be settable in software. A4: Some manufacturers peripherals do strange things and may not work for all converters.

Some converters do not support the break signal. You will need to know if your equipment is grossly non standard. If it is, some converters may work with it. Classic serial ports are ordinarily byte-oriented, ie, one character at a time with quite low latency. USB is inherently packet-oriented, with comparably high-latency. In other words, USB is great for moving a lot of data at once, but it's actually slower at moving tiny amounts of data.

If you try to move a lot of data in tiny pieces with USB, you lose - badly. For just typing on a terminal program talking to a modem or an embedded device, or even uploading files, etc, this is really not a problem, because single doses clnvert the latency are small in human terms, and the USB can easily move blocks of data fast enough keep up with any serial baud rate.

But other protocols which depend on constant back-and-forth of short messages or single characters between ro computer and a serial peripheral can slow to a crawl or even mis-operate when used with usv usb-serial converter.

If a computer does something like send a single character, and wait for the peripheral to respond before sending then next, then the usv rate is determined by the latency for two entire usb packets - one to send a single character, and one to receive one it may even be worse - the receive might at the lowest level involve poling.

In today's world where USB-serial converters are as or more common than real serial ports, go important to design protocols so that isb can send out a lot of data, before needing to wait for a reply. With legacy whatever you like by ti on youtube, you may get lucky and find it works fine, it may work but slowly, or it may not work reliably at all.

And even within a given protocol, peripheral, computer, and operating system driver, the design of the client software matters. I once encountered a piece of management software for concert embedded device which had been written and tested by a contractor using a real serial port. It turned out to use some variation of. NET serial calls that turned out to be "watch the results crawl in" slow on a laptop with a usb-serial converter.

My own previous simple win32 management how to convert serial to usb for that device ran without apparently delay on the same laptop with the same converter. Perhaps I wrote better code, but given that the converter cnvert my ordinary test environment, if there had been a similar problem with my code, I would have been lucky enough to find it while there was how to convert serial to usb time to fix the problem.

Moral of the rant in todays world, anything hardware or even client software designed to use a hlw port should be tested for usability with usb-serial converters early enough in its development that the design can be changed to fix any issues discovered. Amazon page with examples of USB to serial cables. Depending on the speed of the chip, most standard baud rates should be usable, they are on the cable I have here somewhere.

For option 1, what number is barry bonds create a Serial to USB converter, I'd try the Arduniothere are some examples around the webbut I'd only do that if I ran out of ideas for other tl. I found Three famous chips in a site in India an at a very reasonable price.

Yes. Classic serial ports are ordinarily byte-oriented, ie, one character at a time with quite low latency. USB is inherently packet-oriented, with comparably high-latency. In other words, USB is great for moving a lot of data at once, but it's actually slower at moving tiny amounts of data. i need to convert from serial port to USB port? as i had a program that read the COM port rather than USB port.. may i know how to differentiate the different USB port(is there name for it, eg for COM port is COM1,COMwhat about USB port??) Comment. Premium Content You need a . The bridge receives the serial byte into a parallel buffer (at USB speed), and then stuffs the received parallel byte into the parallel side of UART for transmitting it at UART's speed. Before communicating over UART, the USB side must configure the UART for proper baud rate, stop signal length, and use of flow control, as in case of usual UART.

You want to plug a printer into the USB port of your PC, but all you have are older serial cable printers. Instead of using your company's resources, which are probably limited, you decide to buy USB-to-Serial adapters.
