2 Installation
Download PRONET software by visiting www.proel.com
2.1 Requirements
Before installing your copy of PRONET, you must verify that your computer meets some minimum
requirements to work. These requirements are:
- Intel Pentium IV (1.8 GHz or higher)
- 1 GB RAM memory
- Screen resolution 1024 X 768 (minimum)
- 25 MB Free Hard disk space
- USB port (2.0 recommended, also 1.1 supported)
- Windows™ O.S - XP (service pack2) / VISTA / 7 / 8
If your computer meets or exceeds these requirements, the software will be installed and operate without
any problem.
Before starting the installation, be sure to not connect any device to the PC until the end of the installation
process. It is also recommended to close all applications currently in use.
Follow the instructions to install the right drivers at the end of the installation process as explained in the
section “Drivers”.
Note that you must be logged on as an administrator to perform the PRONET software installation steps and
to install the required drivers. Please, verify yours authorizations before to proceed with the installation!
2.2 Software installation
Run the installation program double-clicking on it. This will create a program folder called PRONET (or the
name you have chosen). This folder can be accessed via the Start menu under Programs. The folder contains
shortcut to the program, shortcut to the manual and uninstall.
Note: If you have a software firewall running on your PC, the first time you open PRONET application, or the
first time you goes online and scan the PRONET Network (see “Connecting devices to a network” and
Working online/offline”), probably you will receive a System/Firewall warning regarding an application
called “vscpd.exe”. It is not a virus or a malware, but just a small background application that manages the
PRONET network communication through the USB port. Allow this program to access the network and, if
you can, set the option "Remember my answer and don't ask me again.
2.3 Drivers
The first time you connect a PROEL USB to CAN converter (USB2CAN) or the first time you connect a
PC240/PC260 processor via the USB connection, a “USB2CAN” driver will be requested. Here below we
describe the procedure for installing this driver.
2.3.1 Drivers installation for Windows 7 / 8 (32/64 bit)
You can find the driver files in the default PRONET installation folder:
C:\Program Files\Proel\PRONET\Driver\x86-32bit or C:\Program Files\Proel\PRONET\Driver\x86-64bit
If you have changed the installation folder, you need to specify the new directory path, e.g.
<your installation path>\ PRONET\Driver\x86-32bitor<your installation path>\ PRONET\Driver\x86-64bit
Here below you can find a visual step-by-step guide to install the USB2CAN driver.

Step 1: Connect the USB2CAN converter or the PC240/260 USB connector to the USB port of your PC:
Windows O.S. will detect the new hardware connected and will ask for the drivers.
First of all Windows 7 / 8 will try to download the driver from Window Update repository, skip this
download and proceed with the manual installation of drivers.
Step 2: Open the Control Panel from Start menu and then click to open Device Manager. If you are
prompted for an administrator password or confirmation, type the password or provide confirmation.
Open the list of hardware categories, find the “other devices”/USB2CAN driver that you want to
install/update, and then right-click the name.
Click “Update Driver”, and then follow the instructions. If you are prompted for an administrator password
or confirmation, type the password or provide confirmation.
Step 3: Select the path of the folder driver in the PRONET installation folder.
C:\Program Files\Proel\PRONET\Driver\x86-32bit or C:\Program Files\Proel\PRONET\Driver\x86-64bit
Ignore the Windows warning about the driver publisher.
Step 4: Windows will tell you if the drivers are successfully installed in Windows Device Manager Panel.

3 Working with PRONET
In this section of the manual you will find a brief description of PRONET application, its main windows,
resources and tools to start working. For a detailed description of each feature see the following chapters.
3.1 Application windows
Let’s take a little tour of the PRONET graphic interface to learn how to use it and how to use the graphic
tools.
Fig.12 Description of PRONET graphic windows.
3.2 Device Tree window
Device tree window display a tree list of devices actually connected to PRONET. Every device is listed as a
leaf of the root and is labeled with its main info:
- device's ID, a unique identifier number for each device (see “Connecting devices to a network” or
“Working online/offline”);
- device type and model;
- device name;
If PRONET works online the root of tree is labeled “NETWORK”: in this case the device tree shows every
recognized device connected in the network and its connection status. If the device is correctly connected it
has a green background label, if it is disconnected it has a red background label and a graphic check sign on
its icon.
Fig.13 Connected device.
11
Fig.14 Disconnected device
If PRONET works offline, the root of tree is labeled “VIRTUAL” and the device tree window shows virtual
devices you have added to your virtual network. Virtual devices have gray-background labels.
Fig.15 Virtual devices added working offline.
The device tree also shows the presence of “Group Controllers” (see “Groups and links”). They can be added
either online or offline.
When changing PRONET status from Offline to Online the device tree list is cleared and recompiled,
searching every connected device. When changing PRONET status from Online to Offline the device tree list
is cleared. Group controllers, on the contrary, aren’t automatically removed from the tree; they have to be
removed from the menu option.
Fig.16 Example of devices, controllers and group folders for a virtual network.
Fig.17 Example of devices, controllers and group folders for a network of devices.
12
Devices in the tree list are sorted by their ID or grouped in folders if they are assigned to any group.
A Right-Click of mouse in a device leaf of the tree list opens a contextual menu with some actions available
for the selected device: you can open and close the control panel, or, if you are working offline, you can add
or remove a virtual node.
Fig.18 Contextual menu for virtual devices (working
offline).
Fig.19 Contextual menu for devices (working online).
3.3 Desktop window and control panels
The Desktop window contains the control panel of devices managed by PRONET. Just double-click on the
tree list device label (for a virtual device or a connected device) to open the control panel or use the menu
option
Menu→Device→Open Control Panel.
The control panels are compact windows that display main features, configurations and status (protections,

bandwidth measured at the -3 dB points, or it can be Bw (Bandwidth) in octave fractions with steps of 1/20octave (at -3dB points).
For 1st-order All Pass filters the shape parameter sets the phase (degree) at the reference frequency. For
2nd-order All Pass filters and “Variable Q” LP and HP filters the shape parameter can set only Q (quality
factor) as in analog filters.
For shelf filters the reference frequency is referred to "Gain dB/2" point, in order to obtain a slope-variable
shelving filter from 6dB/oct to 12dB/oct with a "pivot" point at the reference frequency.

plot. This is a global setting. In each editing page you can change temporarily these parameters.
Global graph settings (available only in Advanced Mode): selects what you can plot in the Global Graph
page for the Editing panel of devices. Note that for loudspeaker devices in Global Graph page you can
visualize the amount of equalization from input to output of processing core. For processors devices (e.g.
PC240, PC260) in Global Graph page you can visualize only the output equalization curve, not the input
equalization.
Colors: sets the colors for graphic visualization of equalization curves.
Eq. drag options: sets which parameters can be dragged and edited with mouse in the graphic editing of
equalization curves.
3.9 Save/ Recall Desktop configurations
To easily manage your systems you can save and then recall some basic graphic settings of your desktop
configuration.
In
Menu→File→Save Desktop or Menu→File→Load Desktop you can save and recall your favorite color settings,
the desktop image setting and most of all, the position of opened control panels in the desktop.
Note that the position of each control panel on the desktop is associated to the ID of the controlled device,
so it becomes really useful when you recall a desktop setup for a system already configured.
If you change the ID assignment for a device in a configured system, then the stored ID and panel-position
information don’t match with the new ID. If you recall a desktop configuration the control panel can’t be
placed in the right position.

4 Connecting devices to a network
USB2CAN
converter
Pronet network connection
TERMINATE
USB connection
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.
Fig.27 Schematic diagram for a PRONET network .
19
To work properly in a PRONET network each connected device must have a unique Identifier Number called
ID: by default the PC master controller has ID=0 and there can be only one master controller in a network.
Any other device connected must have its own unique ID equal or greater than 1 and two devices with the
same ID cannot exist in a network.
To correctly assign a new available ID to all devices in a PRONET network follow these steps:
1. power-off all devices;
2. plug them correctly with networking cables;
3. "TERMINATE" last device in the network connection;
4. go to the first device in the network connection;
5. power-on the device while pushing the "Assign ID" button (see "Assign ID");
6. go to the next device in the network and repeat previous operation (from steps 5);
This operation ensures that every device has its own unique ID: if you need to add a new device to the
network you simply repeat the operation at the step 5.
Every device maintains its ID also when it is turned-off, because the identifier is stored in the internal
memory and it is cleared only by another "Assign ID" step, as explained below.
Note 1:if you add a new device as the last device in a PRONET network you have to re-assign correctly the
termination.
Note 2: In a PRONET network the IDs don't need to be sequential, they only must be unique. An example of
this is when you remove or power-off a device correctly assigned and already working into a network: in this
case there is a gap in the IDs sequence but this isn't a problem. Another example is when you add to an
existing PRONET network a new device with the ID already assigned but different from any other already
assigned in the network: again, this is not a problem.
You can also work without a PC master controller and connect a subsystem of active loudspeakers (satellites
or subwoofers): in this kind of network, when you change a preset in a device you also change the same
preset in each connected device of the same type (the same model). Furthermore, when you change the
polarity (phase option) in a subwoofer you also change the same parameter in all the connected subwoofers
(of the same type).
4.2 Assigning ID
The "Assign ID" procedure for a device makes the internal network controller to perform two operations:
1. reset the current ID;
2. search the first free ID in the network, starting from ID=1.
If no other devices are connected (and powered on, of course), the controller assume ID=1, that is the first
free ID, otherwise it searches the next one left free.
To activate the "Assign ID" procedure there is a combination of "Power-ON" and keep pressed a button:
Processor: power-on keeping pressed the "RTA" button;
Active loudspeaker: power-on keeping pressed the "Preset" button;

To work with a PRONET network you need a USB2CAN converter. To install the correct software driver for the
USB2CAN converter see "Installation" and "Drivers" paragraphs.
When you plug in the converter to a USB port of the PC, the LED on box lights in RED, meaning that the
converter is powered but not working yet.
The first time you go "online", the PRONET software application starts checking the network through the
USB2CAN controller, sending and receiving data from connected devices. If everything is OK, the LED on the
top of the converter lights in GREEN indicating the activities on the network.
If there is a problem with the software driver, with network bus or in the converter, the LED flashes in RED
and/or GREEN.
Fig.28 Led color codes for the USB2CAN converter.
4.4 USB connection
For controlling PC240/PC260 devices a direct USB connection is also available. This connection is always
available and enabled for PC240 processor, which doesn't have a network connection. For PC260, which has
both USB and a PRONET network connections, the USB connection is active by default and the network
connection can be enabled in the ‘SETUP’ menu.
Before connecting a processors with USB cable, please refer to "Installation" and "Drivers" paragraphs
because PRONET uses the same software driver both for the USB2CAN converter and the USB connection.
4.5 Working online/offline
PRONET application works in two different modes: online and offline. When online PRONET searches any
connected device, reads all the internal data and continuously checks its status. When offline PRONET works
with “virtual” devices in a “virtual network”.
You can switch from online to offline mode or vice versa in any moment just selecting the option in
Menu→Connection→Online/Offline, or by the toolbar buttons.
Fig.29 Online / Offline toolbar buttons.
4.5.1 Going online
When changing PRONET status from “offline” to “online”, the device tree list is cleared and every virtual
device, if present, is removed from the virtual network. First of all PRONET scans the network searching every
connected device and lists a new device tree. Then it loads the internal data (current status and current
setup of the DSP) of each recognized device.
When online PRONET application constantly checks the status of connected devices: if one of them loses the
21
connection (someone unplugs or breaks the network cables, the device is turned-off, there is an hardware
problem...), its label in the device tree window highlights with a red background, its Edit panel, if open, is
forced to close and its control panel, if open, is disabled and left in its last condition (nevertheless the device
keeps to be checked).
PRONET application detects if a disconnected device is re-activated (i.e. turning it on, or repairing its broken
networking connection): in this case PRONET start a new dump of the device’s data, the label in the device
tree view changes to a green background and the control panel, if open, is re-enabled.
PRONET can also detect if a new device has been connected. If the new device’s ID is a valid one, then
PRONET starts a dump of current data and a new label appear in the device tree. If the ID is not valid,
because there is another device with the same ID in the network, then an “ID conflict” or "Wrong Type"
message will could be displayed in the device tree window or no new devices appear in the tree list.
Fig.30 Wrong type detection. Fig.31 ID conflict detection.
Fig. 32 Example of a Control Panel disabled after the disconnection.
To force a new scan of the network PRONET has a “rescan” function, available in Menu→Connection→Rescan
or by the toolbar button (both available only working online).
Rescan function clears the tree list and re-scan the network searching connected devices.
Fig.33 Rescan toolbar button.
Note 1: rescan function and online function don’t remove the Group Controllers available in the tree list.

4.5.2 Going offline and using virtual devices
When the PRONET status is changed from Online to Offline, the device tree list of connected devices is
cleared. You can work offline adding to a “virtual” network some “virtual” devices. They aren’t real devices
connected in a real network and, for this reason, some functions are not available and there isn’t any data
message transferred by the USB2CAN converter to the devices. The offline mode is useful to configure some
presets for a device and to store them in the hard disk also without the device connected (see “Working with
advanced functions” and "Working with files”).
To add a virtual device there is a menu function
available only working offline).

5 Working with devices
This chapter describes how PRONET application controls connected or virtual devices and how you can
interact with them. A description of the main parameters of the CORE DSP is also included.
For a detailed description of other functionalities see:
“Working with advanced functions” to learn how to use advanced functionalities and obtain the maximum
result from your system.
5.1 Control panels
Control panels are compact windows available for connected devices or virtual devices, which can be opened
in the PRONET desktop windows by double-clicking on a device tree label or by the menu option
Menu→Device→Open Control Panel.
Control panels can display the status of devices (signal/clipping, internal protections, preset currently active,
etc...) and they are also used to access to the setup interface or to access to the DSP parameters of the
controlled device.
5.1.1 Processor panel
PC260 and PC240 have a similar control panel interface, which differs only for the number of outputs
displayed (4 in the PC24, 6 in the PC260). Below there is a brief description of the functions available.
