4. Initial Operation
Follow these four steps when operating the UCC1 for the first time: Connect the UCC1 to the PC and install
the CAN drivers, install the IRIS-Net-software, connect the desired appliances to the CAN-bus, and set the
ISOLATED / GROUNDED switch accordingly.
4.1 PC Connection and CAN Driver Installation
Use the supplied USB cable for connecting the UCC1 to your PC’s or Notebook’s USB-socket. The
computer system normally recognizes the UCC1 at once and the operating system asks for the
corresponding driver software. This files are stored in the root directory of the IRIS-Net CD.
Insert the IRIS-Net CD in your CD-drive and select the corresponding drive in the installation dialog. The
operating system will find all necessary driver files there. For correct installation follow the instructions on
your computer screen. For further information please check the IRIS-Net Readme-File, also.
The UCC1 is ready for operation as soon as the STATUS LED lights.
4.2 Installing IRIS-Net
Next, you have to install the IRIS-Net – Intelligent Remote & Integrated Supervision – software package on
your PC or Notebook computer. Detailed explanation is provided in the accompanying IRIS-Net Readme-
File. Just follow the instructions in the installation dialog.
The STATUS LED blinks whenever the IRIS-Net program is started and accesses the UCC1, indicating that
USB-port data communication has been activated.
4.3 CAN-Bus Connection
The CAN-bus is a serial interface for transferring commands and data. Since the CAN-bus is based on
serial bus architecture, all participating appliances have to be connected in series, i.e. cables have to run
from each participant on the bus system to the next. Whether a connected appliance is an amplifier or the
UCC1 USB-CAN Converter is generally of no further importance, which allows the integration of the UCC1
– and therefore the PC – at any point on the CAN-bus. Including several UCC1s and PCs on a single CAN-
bus is possible as well.
Each participant on the bus system has two RJ-45 connectors for the Remote CAN-bus. These sockets are
connected in parallel to serve as input and output for carrying through the data information of the remote-
network. The CAN-port follows balanced design, which makes the use of Twisted-Pair cables absolutely
mandatory.
Both ends of the CAN-bus have to be terminated with 120 Ω. Two CAN-TERM 120 Ω termination plugs are
supplied with the UCC1. Connect one of these each to the RJ-45 connector that is not in use of the first and
the last appliance on CAN-bus.
The following diagrams are examples of the system cabling for different order of size configurations:
