Monitor Chain

The MONITOR CHAIN connector is a 5-pin terminal block connector. Input and output con- nections are balanced. The center pin is the shield connection for both the input and output of the monitor chain. Connection is shown at right. The left-most + and - terminals are for monitor chain input signals, while the right-most terminals are for monitor chain output sig- nals. When powered down, a relay connects the input to the output, thus bypassing the BASIS 722az in the monitor chain.

RS-232

The RS-232 is a utility serial port for accessing certain diagnostic and setup features. Con- nect to an available COM port on your PC and communicate using a terminal control pro- gram such as Windows Hyperterminal.

Use a normal serial data cable with a DB-9 male plug to connect to the BASIS 722az. To con- nect 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.

Ports

PORT A through PORT D are QSC DataPorts. When using the BASIS 722az with QSC DataPort-equipped amplifiers or QSC DSP products (DSP-3, DSP-4) connect to the BASIS 722az using QSC DataPort cables. The 722az supports up to eight channels of DataPort audio and amplifier status monitoring. This can be four 2-channel amplifiers or one 8-chan- nel amplifier or other suitable combinations.

If connecting a multi-DataPort amplifier, ensure all the DataPorts of the amplifier are con- nected and that they are all connected to the same BASIS.

To connect the cable, orient the connector properly, then push into the receptacle until it is firmly seated; tighten the retaining screws “finger tight”.

LED Indicators

When the BASIS 722az is plugged into a properly functioning AC outlet, it will power up and briefly display a welcome screen on the LCD display.

POWER Indicator- This blue indicator illuminates when the BASIS 722az is plugged into a properly functioning AC source. There is no power switch on the BASIS 722az. This helps to prevent accidental system 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 DIAGNOSTIC LED remains illuminated, try resetting the BASIS 722az by cycling power off and on once.

Should the indication persist, contact QSC’s Technical Services for guidance. During opera- tion, any system fault will fully illuminate the indicator. During a “flash” update, the indica- tor will blink on and off; this is normal. Any error detected will be displayed on the LCD. For purpose of unit identification, the LED can be remotely turned on using QSControl.net soft- ware.
