Texas Instruments TUSB3410

Hello,

Have a look at the TUSB3410 from Texas Instruments.
www.ti.com

They also have a evaluation board with all the docu and code available.

Greetings Mark,

They also send samples.

go and see : www.ftdichip.com

they have a chip named FT8U232AM that is a chip that makes a bridge between USB and RS232.... thus you can use this chip and see it as the COM5 on your PC and send it in USB mode.. It will be then translate into RS232..

Go and see the site for more explanation !

Re: USB to SERIAL

If you need for digital camera I sugest you to by PCI USB board for PC it is cheap (obout 100EUR), and you got very high speed !

hello, i think best solution is to purchase a rs232 to usb converter that you can buy in any computer store.

Re: USB to SERIAL

I agree. Downloading picture files from a digital camera via RS-232 is very slow. In practice more or less unuseable.

Note: A PCI USB board is EUR10, not EUR100. At least where I live...

Hi,

take care because some rs232<>usb converter don't work with modem.
I have try a converter with Prolofic chip who does't work with flux control signal of my modem.

Hi,
What is the speed that can be achieved on this.

 

[totue]

hi,

i don't have made speed test on Prolific chip but a KLSI chip can work at 230kb and a FTDI chip at 230kb.

Re: USB to SERIAL

Hi all;
got one question on this USB to RS232 thing:
when I'm using a VCP driver, how can my software know that the USB device is disconnected?

Re: USB to SERIAL

The TUSB3410 cannot be used because it is a bridge from USB host to RS232.. and it cannot act as a host by itself. That is,

USB host(computer)-->TUSB--->Your device is OK

but not,

RS232 (computer) ----> TUSB--->USB device.

an usb host is necessary at any one side of tusb.
