2 Operational Basics
This chapter provides an overview of the player’s internal operations — Operating
Modes and the player’s Active States; diagrams of the player’s Front and Rear
Panels; a description of the player’s Front Panel Indicators, Player Interfaces,
and Function Switches. Before developing or presenting programs on the
CLD-V2600 or CLD-V2400 the user should read this chapter and become familiar
with the introductory concepts, illustrations and operational basics. (See
Appendix H,
CLD-V2600 & CLD-V2400 Internal Player Controls, for more details.)
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-V2600 and the CLD-V2400 have 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. (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. Turn ON (1) bit 7 of Register C via computer control
to make the CLD-V2600 or the CLD-V2400 enter this mode. Turn OFF (0) bit
7 of Register C to change the operating mode from Test Mode to Normal
Control Mode.
2.1.2 Active States
CLD-V2600 & CLD-V2400 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:
