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-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 CD.
Insert the IRIS 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 Readme-File,
also.
The UCC1 is ready for operation as soon as the STATUS LED lights.
4.2 Installing IRIS
Next, you have to install the IRIS – Intelligent Remote & Integrated Supervision – software package
on your PC or Notebook computer. Detailed explanation is provided in the accompanying IRIS
Readme-File. Just follow the instructions in the installation dialog.
The STATUS LED blinks whenever the IRIS 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:
