How the CMS works

All gaming machines, including linked progressive jackpot controllers, must be connected to the CMS.

Each gaming machine is installed with a gaming machine interface card (GMIC), which carries the machine's unique gaming machine identification (GMID).

The card is connected to a CMS site controller, which is a computer that is located onsite at the venue.

The GMIC records the gaming machine's activity and forwards the data to the CMS site controller every 15 minutes.

Each day, the CMS site controller forwards data collected from all the machines connected to it, to the CMS central computer.

The information collected from each machine is used to calculate the Gaming Machine Tax and to monitor any faults.
