Manual abstract: user guide ELECTRO-VOICE UCC 1
Detailed instructions for use are in the User's Guide.
[. . . ] The minimum distance between parts carrying mains voltage and any accessible metal piece (metal enclosure), respectively between the mains poles has to be 3 m m and needs to be minded at all times. The minimum distance between parts carrying mains voltage and any switches or breakers that are not connected to the mains (secondary parts) has to be 6 m m and needs to be minded at all times. Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible when using original parts. Altering the circuitry without prior consent or advice is not legitimate. [. . . ] CAN ISOLATED / GROUNDED switch Setting this switch to ISOLATED galvanically isolates the CAN-port of the UCC1 from the rest of the circuitry, effectively eliminating ground-loop interference noise. Setting the switch to GROUNDED galvanically connects the CAN-bus to the USB-port ground and thus to the PC.

4. CAN BUS IN / OUT connectors These two sockets are for connecting EV-appliances that are furnished with serial CAN-bus. Both connectors are connected in parallel for convenient carrying through CAN-bus data. MONITOR connector The MONITOR connector provides audio signal output for the monitor bus of EV P-Series Remote Amps. The monitor bus allows listening to the audio signal of any amplifier within the system, without the need for additional wiring.
3. 1 Unpacking
The UCC1 package includes the following parts: 1 UCC1 USB-CAN CONVERTER 1 Front panel 19", 1HU 2 CAN-TERM 120 Ù CAN-bus terminator-plug 4 Rubber feet 1 USB cable 1 Owner's manual Upon receiving your UCC1, please inspect the contents of the package for loss or damage. If any of the here listed parts are missing or damaged, please immediately contact your distributor or a TELEX / EVI Audio service center.
3. 2 Rack-Mounting
The compact UCC1 adapter is mainly aimed for connection to a laptop or notebook computer. However, the supplied 19" front panel allows trouble-free integration in a rack shelf system. In doing so, make sure not to damage, bend or stress the STATUS indicator and the ISOLATED / GROUNDED switch. Reinsert and tighten the two center screws of the UCC1 19" panel (5). Reinsert and tighten the four corner screws of the UCC1 enclosure (6). Now you are able to install the UCC1 in a rack shelf system securing it with the four rack-screws on the sides.
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. Insert the IRIS CD in your CD-drive and select the corresponding drive in the installation dialog. For correct installation follow the instructions on your computer screen. 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. 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. [. . . ] Data Transfer Rate 1000 kbit/s for 40 m 500 kbit/s for 100 m
0 . . . 300 Ù
100 kbit/s for 500 m 62, 5 kbit/s for 1000 m
To reduce the load for the interface driver and therefore also reducing the voltage drop between the two cable ends, using higher impedance termination than the specified 120 Ù is recommended for networks with increased cable length and many nodes on the CAN-bus.
The following table is for estimating the necessary cable diameter in relation to the length and the amount of participants on the bus:
Number of Units on the CAN-bus Bus Length 100 m 250 m 500 m
0, 25 mm respectively AWG24 0, 34 mm respectively AWG22 0, 34 mm respectively AWG22 0, 34 mm respectively AWG22 0, 5 mm respectively AWG20 0, 5 mm respectively AWG20 1, 0 mm2 respectively AWG17
0, 75 mm2 respectively AWG18 0, 75 mm2 respectively AWG18
Additionally, the length of any stub lines for participants that are not directly connected to the CANbus needs to be kept in mind. For data transfer rates of up to 125 kbit/s the length of a single stub cable should not exceed 2 m. The entire length of all stub lines should not exceed 30 m.
General note: Using commercial quality RJ-45 patch cables with a characteristic impedance of 100 Ù (AWG 24 / AWG 26) for rack cabling is generally possible for short distances of up to 10 m. [. . . ]
