Working with Hi Baud Rates Via 422/485

[Kobi_K]

Hi all ,

I'm working with CVI 9.1 and i have 2 PCI Cards :

Advantech PCI Serial port - RS232

FastCom Async PCI-335 - RS422 / 485

I know there is basic serial com lib which contains RS232 Funcs , i also know that those funcs work well with 422 / 485,,,

My problem or Question is that i need to use 6M baud rate which reflects 50MH There is no option to chose this Baud rate at the rs232 func , if i'll enter it manually will it work ?

Or maybe there is an 422 / 485 lib ?

Thank You

You will need to set the FastCom board clock generator to a non-standard frequency. The manual for the card explains how to do this by using Windows API IOCTL function calls. There are also example programs on the CD supplied with the card.
