Hello All,
I have an application that is currently using FTDI USB to serial converter for communication between PC and Controller @ a baudrate of 250kbps with a TTL level output.
We are finding that while we need to transmit between 10-15 bytes of data, the USB frame size is much larger (4kb?) and consequently we are encountering a delay - a lag in processing. (we assume this is the reason for the delayed communication - any experience here would be enlightening)
We are looking for an alternative means of interfacing with the PC through a PCI to Serial communication card. Considering the existing built components, such a card must operate at the 250kb baud at TTL voltage levels.
Do let me know if there is a suggestion on what card can be used for this application.
