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.

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.

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.
