Does anyone have any experiencing in transmitting DEX Audit data from vending machines using M2M?

    Hi Ash,

     

    We have had successful application work with DEX using our INDTU (RS-485/RS-232) for serial connection to cellularvending.jpg

     

    .  Please see below and contact us with any questions that you may have.

     

    Here is the product link:

      My proposal as below. Please note that I was the project leader to equipt the vending machines of Coca Cola in Germany estimated 15 years ago. The Europian vending machines are mainly not using DEX. Anyhow, the operating is close the same. BTW, the battery and charger we maybe can save. The I/Os maybe as well. You can get a downgraded customised solution.
      Regarding antennas I can help as well. To not waste to much money for. My experience I will share with you.
