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 normally-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 connected to the NC terminal and the NO terminal is not connected; when the relay is ener- gized 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 certain diagnostic fea- tures and setup. Connect to an available COM port on your PC and com- municate using a terminal control program such as Windows Hyperterminal.
Use a normal serial data cable with a DB-9 male plug to connect to the RAVE 522aa. 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 522aa is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD dis- play.
POWER Indicator- This blue indicator illuminates when the RAVE 522aa is plugged into a properly functioning AC source. There is no power switch on the RAVE 522aa. This helps to prevent accidental sys- tem shutdowns.
DIAGNOSTIC Indicator- This red indicator illuminates during the power-on self test, then should extinguish. If it remains illuminated, this indicates that the self-test has detected an unexpected event, such as corrupted firmware or a memory boot failure. If the DIAGNOS- TIC LED remains illuminated, try resetting the RAVE 522aa by cycling power off and on once. Should the indication persist, contact QSC’s Technical Services for guidance. During operation, any system fault will fully illuminate the indicator. During a “flash” update, the indicator will blink on and off; this is normal. Any error detected will be dis- played on the LCD. For purpose of unit identification, the LED can be remotely turned on using QSControl.net software.
