CLD-V2800 Level III • Chapter Two 2 Operational Basics This chapter provides an overview of the player's internal operations - Operating Modes and the player's Active States; RS-232C Interface, and Function Switches. Before developing or presenting programs on the CLD-V2800 the user should read this chapter and become familiar with the operational basics. (See Appendix B, C, and D for details on CLD-V2800 Interface Cable Specifications, Internal Player Controls and Internal Player Registers. 2.1 Internal Operations The player's internal operating processes are classified into two groups: Operating Modes indicating player operation status, and Active States indicating player processing status. 2.1.1 Operating Modes The CLD-V2800 has the following two Operating Modes: Normal Control Mode and Test Mode. (See Figure 2-A on next page.) These modes are defined as follows: 1) Normal Control Mode When the player's power is turned on, the player enters Normal Control Mode. In this mode, the player can be controlled by pressing buttons on the front panel, by pressing buttons on the remote control unit, by sending commands via the Pioneer barcode reader, or by sending commands from a computer via the RS-232C connector. 2) Test Mode The Test Mode is set in Register C under computer control.

This mode is used primarily by Authorized Service Company (ASC) personnel to determine key part numbers of the player and to service the player. Generally, the player is not controlled in this mode. 2.1.2 Active States CLD-V2800 processing is performed within several distinct Active States. When a command is executed, the Active State changes inside the player.

Operational Basics
This chapter provides an overview of the player’s internal operations — Operating
Modes and the player’s Active States; RS-232C Interface, and Function Switches.
Before developing or presenting programs on the CLD-V2800 the user should read
this chapter and become familiar with the operational basics. (See
Appendix B, C,

Controls and Internal Player Registers.
2.1 Internal Operations
The player’s internal operating processes are classified into two groups:
Operating
Modes
indicating player operation status, and
Active States
indicating player
processing status.
2.1.1 Operating Modes

Operating Modes
:
Normal Control Mode
and
Test Mode.
(See
