4 Connecting devices to a network
The main purpose of PRONET is to setup and to monitor a system of many active loudspeakers, to configure
easily a single loudspeaker processor or manage a complex system with more processors and loudspeakers.
In order to do that, our engineers have developed a networking system based on a robust, reliable and fast
communication protocol to interconnect every device with simple RJ45 cat.5 (or higher) Ethernet cables.
With a simple operation you can configure the devices to work in a PRONET network, and just only a Proel’s
USB2CAN converter is required.
To configure a single processor (i.e. a PC260 with both USB and PRONET network connections or a PC240
who doesn’t have a PRONET networking connection), there is the possibility to use a direct connection from
the PC to the device by the USB ports.
4.1 Configuring devices for the network
PRONET network is an interconnection of devices, the network can be connected and controlled with a PC,
called "master controller", who can fully control every connected device called "slave device".
PRONET network can also be connected without a PC but only with a sub-system of active loudspeakers.
Devices in the PRONET network are connected with a "bus-topology" by cat.5 (or cat.6) Ethernet cables. The
first device (the PC master controller with its USB2CAN converter) is connected to the network input
connector of the second device, the second device network output is connected to the network input
connector of the third device, and so on. IMPORTANT: the last device connected at the network bus must
be "TERMINATED" by pressing the "TERMINATE" switch near the network connectors in the rear panel of the
device.
