In addition to the basic operations on the main unit and using the remote control, the player is also equipped with an RS-232C-compatible serial control interface allowing connection to a computer. This manual explains procedures and cautions related to controlling the player using this interface. For instructions on using the buttons on the remote control and front panel, refer to the operating instructions included with the player. 2 Serial control 2.1 Interface Specifications 2.1.1 Signal level RS-232C level 2.1.2 Data format Data length : 8 bits Stop bit : 1 bit Parity : None 2.1.3 Signal transfer rate (baud rate) The baud rate is fixed to 115200 (bps). 2.2 Connection to a Computer The computer and player are connected with three wires, as shown on the diagram below. TxD Computer RxD GND RxD TxD GND Player The player accepts commands whenever the power is turned on. Thus, when using with a standard RS-232C port on the computer, there is no need to connect any Confidential Pioneer control wires other than TxD and RxD. With some computers, however, hardware processing of the CTS input is required for operation. In this case a DTR output can be used. As long as signal transfer is possible, a positive potential is output for DTR. Connect the DTR output to the computer's CTS input. 2.3 Commands and Status Processing differs for the remote control button commands and other commands. When the player receives a remote control button command, it sends the "Completed" message (R) and conducts the same operation as the remote control button. As the basic protocol for commands other than "remote control button" commands, the computer issues the command to the player and the player returns the status. Examples: Computer Player (1) "Stop playback" > (2) Playback stops. 99RJ < (3) "Completed" R (4) "Open disc tray" > (5) Disc tray opens. OP < (6) "Completed" R Once execution of the command is fully completed, the player sends the "Completed" message (R). If an error occurs, the player sends the error code, for example "04. The function for returning the status automatically with respect to execution of commands is called "Auto status". The auto status function notifies the computer of the timing for issuing the next command. If the computer does not use this function, the next command must be issued after fully considering the command processing time. There is also the "Request status" function for checking the player's status, making it possible to learn player information and such disc information as the operating mode, time, etc. The main request status functions are as shown below. Confidential Pioneer . ?P – To know the player's operating mode. . ?A, ?R, ?C, ?T, ?I – To know the current time, chapter, title/track number, etc. . ?L, ?E, ?Z – To know the player's information. The status function is as follows: Status report +- Auto status | +- Completed message | L- Error message L- Request status 3 Commands 3.1 Power on Processing When the remote control button "Power" command is sent by RS-232C command while the power is of...
