Computer Control Functions 
2.3.1  Serial Control (see Chapters 3, 4, 5 and 6) 
The player and computer are based upon the RS-232C protocol and are 
connected through the TxD, RxD, DTR and GND terminals. 
2.3.2  Extend Terminal Control (see Chapter 9) 
Control the player with the Extend Terminal Switches (SW#). 
Even if the Key Lock is set (active), the extend terminal control is 
available.

Control the player’s power with the Power Pin within the Interface 
Connector.

the Standby mode, the player powers ON.  If the player detects the same 
signal during the Power ON mode, the player powers OFF and switches 
to the Standby mode. 
The specifications for the Power pin are as follows:
