Hi,

We have a device which does not come with any ready output port for PC. It only come with a BCD data export to LCD display. What we trying to do now is adding aditional parallel cables from the device to the LCD, and make it another additional port to the PC.
While my client pc only have 2 available USB port and no RS 232 port. May I know how can I get the BCD data? Any converter, instrument available in the market?

Please advice.

Regards,
Ching-Yen Beh

Can WinWedge serial communications software communicate over a USB port instead of a RS232 serial port?

They have some low cost modules that allow you to easily interface USB to I/O.
If you're familiar with PICs, one of their modules has an integrated PIC, which would make it simple to read the bcd data and convert it to whatever you need to be sent to the PC via USB.
