4. Rear view of MX R amplifier AyreLink Ground Trigger Input An adapter cable must be fabricated to connect the trigger output of the control component to the AyreLink port of the MX R amplifier The easiest way to do this is to remove the modular RJ 11 connector from one end of a two line telephone line cord This is the type of cord that connects the telephone set to the wall A two line cord will have four gold contacts on each connector Then attach the connector appropriate for the component with the trigger output Please refer to the owner s manual of that component for details 12 volts DC for proper operation The current draw of the trigger input on the AyreLink port is less than 5 mA f The trigger voltage should be between 5 and There are two signaling methods that may be used level and pulse The MX R automatically senses which type of trigger signal is being sent and responds accordingly level sensitive trigger Shorter pulses are treated as a pulse sensitive trigger The minimum detectable pulse length is 50 usec 9 A positive going pulse of greater than 250 msec is treated as a During level sensitive operation applying a voltage to the trigger input will set the amplifier to the Operate mode When the applied voltage drops to zero the unit reverts to Standby In the pulse sensitive mode a positive going pulse will toggle the amplifier between the Standby and Operate states du
