Hi!

I'm sorry but I am not English and I speack English very bad.

My question is: How connect a PC Embedded to Vending Machine? I know
that exist a protocol MDB that is used by vending machine, but this
conector is different to pc conector (RS232, USB, i2c, etc). Can I
connect a PC Embedded by MDB? How?

Anybody understand me?

Thanks you!

We understand you.

Read the spec to understand what is required to connect.

However, even once you have done the hardware to be able to connect to a
PC's RS232 port you will, more than likely run into the problem of the 9bit
char format not being supported on a std PC serial port.

You can fudge it using the mark/space parity control but it is not very
nice.

Why don't you use ccTalk instead?www.cctalk.org
