Relay Out

Two sets of relay contacts are provided, RELAY OUT 1 and RELAY OUT 2. Contacts are floating and rated for 30VDC, 1A. There is one common terminal, one normally-closed contact terminal and one nor- mally-open contact terminal. These are labeled as C, NC and NO on the rear panel. When the relay is not energized, the C terminal is con- nected to the NC terminal and the NO terminal is not connected; when the relay is energized the C to NC connection is opened and the C to NO connection is closed.

RS-232

The RS-232 is a utility serial port for accessing diagnostic and setup features. Connect to an available COM port on your PC and communi- cate using a terminal control program such as Windows Hypertermi- nal.

Use a normal serial data cable with a DB-9 male plug to connect to the RAVE 520uz. To connect the cable, orient the connector properly, then push into the receptacle until it is firmly seated; tighten the retaining screws “finger tight”. Communications should be 9600 baud, no parity, 8 data bits, 1 stop bit, and flow control Xon/Xoff.

LED Indicators

When the RAVE 520uz is plugged into a properly functioning AC out- let, it will power up and briefly display a welcome screen on the LCD display.

POWER Indicator- This blue indicator illuminates when the RAVE 520uz is plugged into a properly functioning AC source. There is no power switch on the RAVE 520uz. This helps to prevent accidental system shutdowns.

DIAGNOSTIC Indicator- This red diagnostic LED reports several possible operational conditions. During boot-up, it is used to continu- ally blink a “dot-dash” pattern if the power-on memory self-test fails. During normal operation, if any non-recoverable system fault occurs, the diagnostic indicator will remain on, requiring a power restart. If this condition persists, contact QSC’s Technical Services for assis- tance.

The diagnostic LED is also used to indicate an update is in progress during a remote firmware update cycle. First, the LED will blink slowly, indicating the memory erase cycle, then it will blink rapidly, indicating the memory write cycle. NOTE! During a firmware update, it is critical the unit remain powered on for the entire process in order to complete successfully.

The diagnostic LED may also be controlled by using the QSControl.net software. This feature is particularly helpful for identifying a particu- lar unit.
