Hi, I need to get the count of mechanical counter like used in spending machine. And when requested in main computer get the count using a phone line.
Can someone give a suggestion, any device that could help me?
Thank you. W.S.
How simple does it have to be?
How cheap does it have to be?
Easy if you can set up a PC at the remote end.
What matters more..the manpower to design and build it or the final cost of the parts?
There are lots of data loggers with modem capability..
Google can find them easily. Examples...
It's very simple, I only to store 3 different counts and send it when requested.
Very cheap.
I can have a PC and develop the software to make a resquest and get the data in one but in the other side must be a little device.
I want a electronic card that can store the counts and make the interface I don't want to build this card.
The data logger I have found have a high price.
Should be able to find a development board for a single chip micro with an onboard modem.
