The CT3 Vending Tester Pro from SEM is capable of testing all coin changers and bill acceptors on the North-American market. It supports many protocols, old or new, and is equipped with the SSPS Overload feature protecting the unit against shorted devices.

Furthermore, the CT3 offers 3 programmable selections enabling you to test your MDB equipment in real life situation and even more than one at a time.

*Note.  To test any validator that is not MDB, you will need to get the External Bill Validator Module, or EBVM (part number A01070), in order test your 110 volt and pulse bill validators.  The EBVM plugs directly into the CT3 tester.  The tester without the EBVM will test all coin changers.  No extra module is needed for coin changers.  The EVBM can be purchased here: https://www.ebay.com/itm/226429654033
