3.5 Command Formats
Level III commands on the CLD-V2800 are expressed as “Command Mnemonics”, so
they are easy to remember. “Command Mnemonics” are also used for Level III control
of the CLD-V2600, CLD-V2400, LD-V8000, LD-V4400, the LD-V2200, & LD-V4200
(a discontinued models), the LC-V330 Autochanger, as well as for the LD-V4100 (PAL
player), CLD-V2300 (NTSC/PAL) and the LD-V4300D (NTSC/PAL player). Some
commands are preceded by an “argument” expressed as an integer. These may
indicate a specific “address” location on the disc or set function parameters.
Command Mnemonic
— Each Level III command is expressed as two ASCII
alphabetic characters, representing the command mnemonic. There is no
distinction between uppercase letters and lowercase letters. Example: PL (Play);
Pl (Play); pl (Play).
Argument
—An argument is expressed in ASCII digits and it is placed before the
command. When a command requiring an argument has no argument, an error
(E06) is returned. An argument consists of either an address or an integer:
1)
An Address
— The address can be a frame, time, or chapter number (LDs) or time,
block, track or index number (CDs) depending how the address flag is set. When an
address larger than the maximum allowable value is input, correct evaluation cannot
be made. Addresses may be expressed as numbers indicated below:
