AYRE VX-5 - Manual (Page 13)

The unused AyreLink port on the amplifier is then
used as a trigger input.
Rear view of VX-5 amplifier. An adapter cable must be fabricated to connect the
trigger output of the control component to the
AyreLink port of the VX-5 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 source 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 VX-5 automatically senses
which type of trigger signal is being sent and
responds accordingly.
