Controlling the AR-200 from an External Device (Control Input Connectors)
Applications
AR-200 Settings
Selecting the Control Input Mode
Set the MODE switches on the AR-200’s bottom panel to
select “DIRECT PLAYBACK” from the control input modes
(PLAYBACK BY CARD DATA/DIRECT PLAYBACK/
BINARY PLAYBACK/INTERVAL PLAYBACK).
You cannot achieve control input playback merely by
connecting a device to the port. Be sure to set the control
input mode and match the method used for connecting to the
connectors.
Procedure for Setting the Control Input Mode
1. Turn off the power of the AR-200.
2. Set the MODE switches on the AR-200’s bottom panel as
shown below.
SW1: ON
SW2: OFF
3. Turn on the power of the AR-200.
* Use a pointed object to change the ON/OFF settings of the
MODE switches.
Assigning Phrases to the Terminals
Assign phrases 1 through 9 to Port Nos. 1 through 9.

Specifying Phrases in Binary
Notation (Binary Playback)
What Is Binary Playback?/Use
and Applications
By inputting binary (Base 2) signals to Port Nos. 1 through 8
to select a phrase and inputting a start message to the START
terminal, you can then play back the selected phrase. A
maximum of 250 phrases can be selected and played back
with this method.
This allows you to specify 250 phrases with control signals
(from a switch or other ON/OFF signal device), without
having to use computers or other complicated equipment.

* To conduct Binary Playback, you will need to obtain a control
device capable of generating binary signals.
* Input of binary specifications should be completed in no more
than 50 milliseconds.
Connecting External Devices
Connectors Used in Binary Playback
“1–8”: Phrases are specified in binary format using
combinations of 0 (Off) and 1 (On).
“9 (START) “: Start phrase playback.
“10 (STOP) “: Stop phrase playback.
In addition to the connectors just described, shorting the 11/
12 (GND) (Ground) connectors enables “On.”

"Important Notes on Making Connections and Switching
the Power On and Off" (p. 9)
Even without connecting to all eight connectors used for
making the binary specifications, you can still conduct
Binary Playback. The number of phrases that can be specified
is determined by the formula “two to the nth power minus
one” (with “n” being the number of connectors used).
Example:
Using three timers or other such devices capable of
outputting the necessary signals gives two to the third power
minus one (i.e., 8 - 1 = 7), meaning you can specify the seven
phrases 001 through 007.
However, start signals feature other special requirements.
