This board is sold to experienced vending/ bill changer techs in quantities of 10.   This will allow work with your local customers and update their machines.  If the host machine has an issue in the future, you will need to continue working with your customer.  In most cases, the host board enable line is not active, or a different model of Mars validator was installed after the first validator and the installer did not set the dip switches properly.  In the event, the low-level interface of the validator is not working, then the validator will need to be repaired.

This board can be sold individually if Capital Vending repairs your validators as this way, we are certain the low-level interface of the validators is working and dip switch settings are noted.  Please contact us if Capital repairs your validators and you need to buy this board in small quantities.
