About the Centralised Monitoring System

The Centralised Monitoring System (CMS) commenced operation for assessment purposes on 1 December 2001. Maxgaming NSW Pty Ltd, a Tattersall's Company, currently holds the licence to operate the CMS.

Data Monitoring Services (DMS), a division of Maxgaming NSW Pty Ltd, operates the CMS and uses it to monitor and report the performance of all gaming machines in New South Wales. DMS uses this information to assess the gaming machine tax due for each of the states' more than 3,000 gaming venues. DMS also provides the NSW Office of Liquor, Gaming and Racing with gaming machine integrity information.

Our office provides the CMS with daily updates on changes to premises contact details (licensees, business owners etc) and gaming machine entitlements.

Our office's CMS Business Unit:

The Office of State Revenue (OSR) collects all gaming machine tax payable.


How does the CMS work?

All gaming machines, including Linked Progressive Jackpot Controllers, are required to be electronically connected to the CMS. To enable this to occur each gaming machine has a Gaming Machine Interface Card (GMIC) installed, which in turn, is connected to a Local Area Network (LAN) that is connected to a CMS site controller. This is a computer that is located in the cabinet or the CMS rack in each venue.

The GMIC records and stores meter readings as the gaming machine emits them. The reading may also include unusual events as they occur. These are known as integrity events and include such events as a RAM reset. At 15 minute intervals, these readings and events are forwarded to the CMS site controller.

Each day at 10am the GMIC also takes a freeze meter reading. This reading forms the basis for compiling reports and calculating metered profit of each gaming machine. Each day the meter readings and integrity events are forwarded from each CMS site controller to the CMS central computer. The transfer of data occurs automatically.

The CMS identifies machines by their unique GMID (Gaming Machine Identification) number, not the serial number displayed on the compliance plate. It is therefore extremely important that the correct GMID is entered into each gaming machine.
