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

I read a little about spec of "ccTalk", and this is other protocol,
no?

I need "to talk" with a vending machine. The standard of vending
machine is the MDB (i think).

Are you understand me?

Thanks you.

Here is a USB to MDB bridge :

htm
(sorry for the spanning)

Here is the protocol :
http://www.vending.org/technical/MDB_3.0.pdf

www.vending.org is where you need to go for any info about MDC/ICP

Thanks you!!

I know this all, but the "USB to MDB" is not a good solution for me,
should be others solutions...

I am interesting in ccTal PhilW but i dont understand how apply this
to the vending machine.

Thanks you.

If the vending machine does not speak CCTalk then there is no way to 
apply it at all, in this case.  MDB/ICP is the way you will have to go.
CCTalk was designed more along the lines of gaming systems and MDB was 
designed for vending machines and the like.  Not that you couldn't use 
CCTalk in a vending machine, but MDB was standardized for use in them 
(vending machines) long ago.

Oh James Beck, i think that you have reason.

My problem is how comunicate the pc embedded with vending machine with
the protocol MDB... If the unique solution the "MDB --> USB adapter"?
If you sum the price that a pcembedded+adapter ... for one for machine
is very expensive no? it must of having another solution, no?

Thanks you!

Well, if you doing a one off machine, there will never be any economy of=20
scale.  If I were doing a single machine/test station, I wouldn't balk=20
at paying the price for the adapter.  If I were doing thousands of them=20
I would look at doing something more task specific and cheaper.  You can=20
implement the protocol yourself with some kind of adapter for the PC and=20
a communications library, but that would be what the specification is=20
for.
