Controls And Connections - Electro-Voice UCC 1 Owner's Manual

2. Controls and Connections

1. USB connector
This connector is for the connection to the USB-port on your PC. The interface complies with the
USB 1.1 specifications and offers data transfer as well as operation voltage supply for the UCC1.
2. STATUS indicator
The STATUS LED indicates the actual operational state of the UCC1. The indicator lights when
the UCC1 has been connected to the PC, the dedicated driver software has been installed, and the
PC has recognized the unit. The LED blinks during data accesses.
3. 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.
5. 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.
