Rear view of MX-R amplifier.
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.
The trigger voltage should be between +5 and
+12 volts DC for proper operation. The current
draw of the trigger input on the AyreLink port is
less than 5 mA.
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.
A positive-going pulse of greater than 250 mS is
treated as a level-sensitive trigger. Shorter pulses
are treated as a pulse-sensitive trigger. The
minimum detectable pulse length is 50 µS.
