Controlling the AR-3000R from an
External Device (Control Input Terminals)
You can control the unit from an external device by using the
input terminals, among the screw-on control terminals on the
unit’s rear panel.
This chapter describes how to connect external equipment
and make the settings on the AR-3000R.
To confirm phrases when selecting a phrase, you can use the
PLAY and STOP buttons to play and stop phrases, and the
PAUSE button to pause phrases. Note that you cannot
change settings during phrase playback.
What Is No-voltage/Make-
contact?
This is a contact that makes starting possible simply by
connecting two lines to the control input terminals and
shorting their ends. This is a general-use method that lets
you create start systems easily using only a switch and
without any need for a power source, enabling easy use for a
variety of applications.
You can control recording and playback on the AR-3000R by
on and off signals input from an external device through the
no-voltage/make-contact or open collector circuit.
The range of situations where you can use the unit can be
expanded by connecting infrared sensors, external-start
connectors such as switches, relays, and timers, and the like
to the unit.
The AR-3000R can help simplify installation operations by
making the starting-side contact hot and sharing the ground
as the common (COM) port.
Also refer to “Examples of Usage and Connection for the AR-
3000R” (p. 19) for more examples of usage of the control
input and output terminals.
For information about the specifications of the control input
and output terminals, refer to “Specifications of the Control
Input/Output Terminals” (p. 137).
Important Notes on Using the Control Input
and Output Terminals
* The control input and output terminals cannot be used to
switch the power to the AR unit on or off.
* The two common (COM) ports are connected internally, so
you can achieve operation by making the connection to either
one. At times such as when connecting more than one AR
control port to a single make contact, interconnect one COM
port from each AR. However, do not intermix this unit with
other AR series devices. Doing so may result in unstable
operation.
When making connections to the ports, be careful not to lose
the removed screws. Place the screws out of the reach of
small children. If a screw is accidentally swallowed,
immediately consult a physician.
Types of Control Input Playback
The varieties of control input playback are direct playback (p.
86), program playback (p. 89), and binary playback (p. 92).
The three playback methods yield the following nine types of
operational specifications according to their settings. Choose
the one that matches your usage conditions.
• Direct Playback (NORMAL)
• Direct Playback (FIRST-IN)
• Direct Playback (LAST-IN)
• Direct Playback (SEQUENCE)
• Program Playback
• Binary Playback (Level: OFF; Edge: OFF)
• Binary Playback (Level: ON; Edge: OFF)
• Binary Playback (Level: OFF; Edge: ON)
• Binary Playback (Level: ON; Edge: ON)
* Different types of playback cannot be carried out at the same
time.
