## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims the benefit of priority to Australian Provisional Patent Application No. 2007905240, filed on Sep. 25, 2007, entitled “A GAMING NETWORK”, which is herein incorporated by reference in its entirety.
FIELD OF THE INVENTION
The present invention relates to a gaming network of the type including a plurality of gaming machines in networked communication with one or more gaming control and/or administration devices.
BACKGROUND OF THE INVENTION
It is known to provide a gaming network of the type wherein multiple gaming machines are connected together in a master/slave type arrangement. In one implementation, a bus is connected to a master/slave control device and each gaming machine is connected to the bus. Communications between the master/slave control device and the gaming machines are controlled by the master/slave control device and are based on conventional master/slave type protocols. This type of gaming network is generally implemented in accordance with RS485 standards.
More recently, it is becoming increasingly common to replace such RS485 master/slave type gaming networks with point to point Ethernet type gaming networks wherein multiple gaming machines are connected in a point to point type arrangement with a network switch and through the network switch to a gaming control device.
However, in order for a business to transition from a master/slave RS485 type network arrangement to a point to point Ethernet type network arrangement significant expense will be incurred including costs in replacing master/slave based gaming machines with point to point Ethernet based gaming machines.

FIG. 1 is a schematic diagram of a gaming network in accordance with an embodiment of the present invention; and
FIG. 2 is a schematic diagram of the gaming network shown in FIG. 1 with the gaming network incorporating a patch panel.



The foregoing summary, as well as the following detailed description of certain embodiments of the present invention, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the invention, certain embodiments are shown in the drawings. It should be understood, however, that the present invention is not limited to the arrangements and instrumentality shown in the attached drawings.
DESCRIPTION OF CERTAIN EMBODIMENTS
Referring to FIG. 1 of the drawings, there is shown a gaming network 10 which is capable of connecting to gaming machines 12, 14 of the type using a master/slave type protocol and to gaming machines using point to point type protocols through a common point to point cabling infrastructure 16.
The gaming network 10 is connectable to at least one first gaming machine 12 arranged to communicate using a master/slave type protocol, and to at least one second gaming machine 14 arranged to communicate using a point to point type protocol. In this example, each of the first and second gaming machines 12, 14 connects to the point to point cabling infrastructure 16 using first twisted pair cables 18 terminated with RJ45 type connectors. A suitable twisted pair cable is a CAT-5 cable commonly used in conventional Ethernet networks.
In this example, the point to point cabling infrastructure 16 includes a plurality of second twisted pair cables 19, each second twisted pair cable 19 being terminated at a RJ45 type socket.
The first gaming machines 12 are connected through respective second twisted pair cables 19 in the point to point cabling infrastructure 16 and through respective third twisted pair cables 24 to a master/slave interface device 20, and through the master/slave interface device 20 to a master/slave control device 22. As with the first cables 18, in this example the third twisted pair cables 24 are terminated with RJ45 type connectors.
The master/slave control device 22 is arranged to handle administration of the first gaming machines 12, to control the status and properties of the first gaming machines 12, and to monitor information associated with the first gaming machines 12 such as the bandwidth, and CPU and memory usage associated with the first gaming machines 12. The master/slave control device 22 may be referred to as a site operator terminal (SOT).
The second gaming machines 14 are connected through respective second twisted pair cables 19 in the point to point cabling infrastructure 16 and through respective third twisted pair cables 24 to a network switch 26, and through the network switch 26 to a LAN control device 28. The third twisted pair cables 24 are in this example terminated with RJ45 type connectors.
The LAN control device 28 is arranged to handle administration of the second gaming machines 14, to control the status and properties of the second gaming machines 14, and to monitor information associated with the second gaming machines 14 such as the bandwidth, and CPU and memory usage associated with the second gaming machines 14. The LAN control device 22 may also be referred to as a site operator terminal (SOT).
As shown more particularly in FIG. 2, a patch panel 30 may be incorporated into the gaming network 10 between the point to point cabling infrastructure 16 and the master/slave and LAN control devices 22, 28 so that by appropriate connection of RJ45 connectors 32 of patch cables 34 between the patch panel 30 and the master/slave and LAN control devices 22, 28, a gaming machine 12, 14 may be connected through the point to point cabling infrastructure 16 to either the master/slave interface device 20 or the network switch 26.
As shown more particularly in FIG. 2, the master/slave interface device 20 includes a communications bus 40 connected to a master socket 42, in this example of RJ45 type and a plurality of slave sockets 44, in this example of RJ45 type also connected to the communications bus 40.
It will be appreciated that by connecting the master/slave control device 22 to the master socket 42 through the point to point infrastructure 16 and connecting each first gaming machine 12 through the point to point infrastructure 16 to a slave socket 44, it is possible for the master/slave control device 22 to communicate with the first gaming machines 12 through the point to point infrastructure 16 using a suitable master/slave protocol.
It will also be appreciated that by connecting the LAN control device 28 to the network switch 26 through the point to point infrastructure 16 and connecting each second gaming machine 14 through the point to point infrastructure 16 to the network switch, it is possible for the LAN control device 28 to communicate with the second gaming machines 14 through the point to point infrastructure 16 using a suitable point to point protocol.
It will be understood, therefore, that with certain embodiments of the present invention it is possible to incorporate gaming machines of master/slave protocol type and point to point protocol type into the same gaming network and to use a single point to point cabling infrastructure to communicate with the gaming machines. As a consequence, it is possible for a gaming operator to install a point to point cabling infrastructure so as to implement a point to point Ethernet type gaming network whilst maintaining the ability to communicate with legacy gaming machines of master/slave protocol type.
It will also be understood that should any of the legacy master/slave protocol type gaming machines 12 be replaced with a point to point protocol type gaming machines 14, the respective connection to the master/slave interface device 20 need only be connected instead to the network switch 26. This is easily facilitated in the example shown in FIG. 2 by appropriate connection of the relevant patch cables 34.
