CBS Installation
The following sections describe the preparation, cabling, and
installation of the CBS and its related components.
CBS Ethernet Cable Connections
The RealPrice CBS uses a star topology and has an integrated Ethernet
switch that can connect to three other CBSs. RealPrice supports up to
three (3) levels below the primary CBS. This topology results in the 85
CBS maximum mentioned in the “General Layout Instructions”
section. The following illustration shows an example 85 CBS
configuration, its Ethernet cable connections, and the maximum
number of CBSs on each level.
