B.1
RDB Unit Network Connections
RDB units operate on a standard network, made of standard network cables and a network hub.
RDB units are connected through a Main RDB Network Switch, that links all the RDB units
together with the second network card of the Front Desk PC.
Qubica supplies RDB Network Switches with 16 ports, this poses a physical connection limit to
30 lanes: 15 RDB units plus the Front Desk connection. Qubica also supplies the network cables
needed for the installation, each cable’s length is dimensioned according to the distance between
each RDB unit and the Network Switch.
The connection between the Main RDB Network Switch and the Front Desk operates on a
standard network cable, that must not exceed 300 feet – 100 m. Qubica supplies a 300 feet-long
Cat.5 Network cable for the installation.
B.1.1
RDB Network in centers with more than 30 lanes
If the bowling center has more than 30 lanes, or if the lanes are divided in two or more groups,
additional RDB switches that act as slaves are needed.
The lanes’ groups must be equally balanced in homogeneous groups. Qubica supplies the
additional switches and the network cables.
Example : a bowling center with 34 lanes is split into two sub-centers, one with 18 lanes
and the other with 16 lanes. Qubica supplies the Main RDB Switch, the two additional
slave switches, one kit of cables for a 18 lanes center, one kit for a 16 lanes center and
three Cat.5 300 feet – 90m cable coils, one for each switch (1 main, 2 slave).
The Slave switches must be connected to the Main RDB Switch in UPLINK mode. UPLINK
mode is automatically set in switches supplied by Qubica, other switches may need a manual
setting.
When multiple switches are involved it is mandatory not to connect any RDB directly to the
Main RDB Switch, between each RDB and the Front Desk PC there must always be the same
number of switches, and these switches must never exceed the number of two.
The network kits are supplied with some extra spare RJ45 connectors and caps, to be used to
repair damaged cables. Installers should have a spare set of RJ45 connectors, the specific tools
needed for the job and a network tester.
Qubica suggests the installation of a cables’ conduct along the whole length of the curtain wall,
to accommodate the network and the audio-video cables.
B.2
Console Connections
The connection between the RDB on the curtain wall of the center and the lane consoles on the
front side is made with standard network cables, supplied by Qubica.
NOTE: The signals running through the console cables are not standard network signals, DO
NOT CONNECT the console cables to standard network equipment.
Each console has its own cable coming out from the RDB unit. It is suggested to lay a conduct
for cables under the cappings. This conduct will also accommodate the L-COM cabling towards
the T-Vision, and the Q-Foul units.
