Specifications of the Control
Input/Output Terminals
fig.21-02e
1. Control Input
Trigger Signal Format: On, Off (Open, Close), Pulse width:
20 msec or more
Contact capacity: DC 24 V, 0.1 A or more
Input: Photocoupler
Pins used for control input:
• Direct playback: 1–16, STOP, COM
• Program playback: START, STOP, INC, DEC,
EXCHANGE, COM
• Binary playback: 1–10, 11, START, STOP, COM
• Control-port recording : 1–10, 11, 13, 14, COM
* Time from make-contact onset until playback starts is
approximately 40 ms (typ.). However, please be aware that this
may vary slightly depending on card type.
* During binary playback, complete input specifying binary
signals within 50 ms.
* The two common (COM) connectors are connected internally,
so you can achieve operation by making the connection to
either one. In cases such as when you are connecting the
control connectors of a number of AR units with a single
make-contact point, connect one COM connector on each AR
unit to each other. However, do not intermix this unit with
other AR series devices. Doing so may result in unstable
operation.
2. Control Output
Signal system: No-voltage make-contact
Contact capacity: DC 30 V, 5 A
Connectors used with control output:
• Busy Out: BUSY OUT
• Control Out: CONT OUT, make-contact time: 1 second
3. Audio Output Ports (MONO OUT)
MONO OUT is an audio output (mono, unbalanced) ports.
Rated output level: +4 dBu
Output Impedance: 500 ohm
Recommended Load Impedance: 10 k-ohms or greater
* The control I/O connector cannot be used to switch the power
to the AR unit on or off.
* The output levels may change for stereo and mono audio
phrases.
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.
RS-232C Connector
Specifications
Transmission method: Start-Stop synchronous system
(Asynchronous)Duplex data transmission
Baud rate: 4800 /9600/19200/38400 bps
Parity: none
Data length: 8 bit
Stop bit length: 1 bit
Code set: ASCII
* The setting “38400” bps is for compatibility with legacy
models (AR-3000/2000). However, it is a value for the
communication speed that is not defined by the RS-232C
standards.
