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-Aon 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. (See page 4-43) It is used for player maintenance and management. 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. If you consider player processing as a series of events within the Active States listed below, it is easier to understand the effects of various commands. The player’s five main Active States are:

• Door Open • Park • Spin Up • Random Access • Spin Down
