7 MUTE port: The MUTE connector makes it possible to connect a power freecontact to totally silence the CA40 if an external device works on it (example: aemergencies and centralised evacuation warning system). RS-232 port: the serial communication port RS-232 allows remote management ofthe CA40 from a computer or external control system supporting this protocol. Seethe CA-NET protocol manual for detailed information on the connection and syntaxof the commands supported. The connection has the following specifications:o Baud rate: 9600 (fixed, without auto negotiation)o Data bits: 8o Parity: Noneo Stop bits: 1o Flow control: None Receiver IR: the built-in IR receiver gives general volume control of the CA40 andits MUTE ON / OFF function from the REVO-IR remote control included with theunit.4. OPERATION AND USAGE4.1. Start up and default modeStart up the CA40 by connecting the equipment to an external power source to whichthe DC 24V connector of the CA40 has already been connected. The LED indicator ON/STBYimmediately lights up on the front panel. We recommend you turn on all the devices in thefollowing order: sound sources, mixer, equalisers, active filters and processors and, finally poweramplifiers. Powering off should be done by following the exact reverse sequence. Following thisorder, the introduced noise due to turning on or switching off the devices will not affect thosefurther on in the chain and will be inaudible.The system defaults to volume adjustment mode. In this mode, the VOL/MUTE knob onthe front panel acts on the general output volume of the CA40. This controller has a maximum of64 steps between the unit's minimum and maximum volume. When turned, it will adjust thevolume while the LED LEVEL light is flashing. When the controller is turned to the left or to theright, this flashes while the output volume increases or decreases. The light stops flashing when itreaches either end of the scale and it is no longer possible to increase or decrease the volume ofthe unit.Quickly press the VOL/MUTE controller to activate/deactivate the mute function of theunit (MUTE ON/OFF). The MUTE LED lits when the mute function is activated.If you adjust the volume using the infrared remote control, the LED LEVEL y MUTEvisual indicators are exactly the same as those seen when adjusting these with the knobs on thefront panel.WIRING RS-232 – DB9RS-232 CA40 DB9Tx Pin 2 (RxD)Rx Pin 3 (TxD)Gnd Pin 5 (Signal Gnd)
