1-2 TP 120 v. 1.0 • 10/95 CLD-V2800 Level III User’s Manual • The CLD-V2800 is well-suited to use in kiosks, due to its small footprint. Dimensions in inches: 12-5/8” (w) x 15-11/16” (d) x 5-1/16” (h) . • It has a 10 line x 20 character user display. (The same number of lines as the CLD-V2400). • The CLD-V2800 responds to a superset of RS-232C Level III commands available on the CLD-V2600 and CLD-V2400. It responds to all the same commands plus one additional command, the Picture Stop Command. This command enables or disables picture stops that are encoded on a disc. • The headphone jack with volume control and the front panel illuminated display help to make this player ideal for use in individual work stations or as part of multimedia “creation stations”. • Composite Video or RF Modulated V ideo outputs provide for connection to a video or TV monitor . • The CLD-V2800 player can be used for Level I or Level III control of LaserDiscs (LDs), compact audio discs (CDs) or compact video discs (CDVs). The three player control methods are: • Level I — Manual Contr ol using a remote contr ol unit (CU-V113 & RU-V103), using a Pioneer barcode reader , or using the player’s front panel buttons. (LD/CD) • Level II — Inter nal Pr ogram Control by loading Level II programs into a Level II compatible player’s memory. Usually the pr ograms are specially encoded onto a Level II videodisc. The CLD-V2800 player does not have built in Level II capability. The LD-V8000 is the only industrial level model with Level II capability. • Level III — Exter nal Computer Contr ol by sending commands from a computer to the player via the RS-232C serial interface. (LD/CD) NOTE: The use of the ter m CD in this manual refers primarily to CD audio discs and includes, by inference, CDVs. NOTE: For infor mation about Level I contr ol of the player using front panel buttons, remote control unit or LaserBarcode, please see the Operator’s Instructions that ship with the player .

2 Operational Basics This chapter provides an overview of the player’s inter nal operations — Operating Modes and the player’s Active States; RS-232C Inter face, and Function Switches. Before developing or presenting programs on the CLD-V2800 the user should r ead this chapter and become familiar with the operational basics. (See Appendix B, C, and D for details on CLD-V2800 Inter face Cable Specifications, Inter nal Player Controls and Inter nal Player Registers. 2.1 Internal Operations The player’s inter nal 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: Nor mal 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 tur ned on, the player enters Nor mal Control Mode . In this mode, the player can be controlled by pressing buttons on the front panel, by pressing buttons on the remote contr ol unit, by sending commands via the Pioneer barcode reader , or by sending commands from a computer via the RS-232C connector . 2) T est Mode The Test Mode is set in Register C under computer contr ol. (See page 4-43) It is used for player maintenance and management. This mode is used primarily by Authorized Service Company (ASC) personnel to deter mine 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 per for med 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 ef fects of various commands. The player’s five main Active States are: • Door Open • Park • Spin Up • Random Access • Spin Down CLD-V2800 Level III • Chapter Two CLD-V2800 Level III User’s Manual TP 120 v. 1.0 • 10/95 2-1
The player is in Door Open before the disc is loaded into the disc tray. After the door is closed, the player enters Park. When a STAR T or PLA Y command is input while the player is in Park, the disc starts rotating and the player enters Spin Up . When the player is ready to play images, it enters Random Access. Random Access is further divided into Play, Still , Scan, Pause, Multi-Speed , Skip (Chapter and T rack) and Search. When a REJECT command is received, the player enters Spin Down Mode. Image playback stops immediately, and disc rotation is gradually stopped, then the player enters Park . Figure 2-B, describes how the active states change within the player .

4) Connection to a Computer The player can be connected to a computer via the RS-232C port as shown below. It is connected with three lines: One line transmits commands from the computer to the player to control operations. Another line transmits status responses from the player to the computer . The thir d line is Ground. The player does not use hardwar e handshaking. Therefore, contr ol or “handshaking” lines other than TxD and RxD are not r equired, even if the computer provides them. Some computers, however , may require hardware handshaking. The player makes a line available to be used, as needed, by the computer . The DTR signal is always pulled high inter nally, within the CLD-V2800. The player is connected to the RS-232C port of the computer as follows: See Appendix B for specific inter face cable pin configurations to use to connect various computers to the CLD-V2800.

2.3 Function Switches The CLD-V2800 videodisc player has four physical dip-switches, #1-4, on the rear panel of the player (See Figure 2-G below.) These are used to set several function parameters. All switches are set as follows when the players are shipped from the factory: Switch 1: DOWN and Switch 2: UP sets the BAUD set to 4800; Switch 3: UP Auto Start set to OFF; Switch 4: UP Squelch is Blue. SW1 and SW2: These two switches ar e used to set the BAUD rate of the Player for RS-232C communications to 9600, 4800, 2400, or 1200 BAUD. The factory set default is 4800 BAUD, with Switch 1 DOWN and Switch 2 UP . SW3: Auto Start Automatic playback starts when a disc is inserted and SW3 is DOWN=ON. Default is No Auto Start: UP=OFF . SW4: Background for setting squelch color: Black is DOWN=ON; Blue is UP=OFF . Default is Blue: UP=OFF . NOTE: Settings for Load Start, Power -On Start, 4800 or 1200 BAUD Rate, and Background Color can be modified by entering data into Register C from a computer via the RS-232C port. (See Section 3.7.6 Register Contr ol Commands, Register C Set, page 3-42.)

3 External Computer Control — Level III This chapter describes the computer control pr otocol and specific commands used for Level III control of the CLD-V2800 player . T o attach a computer to the player via the RS-232 port, refer to Appendix C , Inter face Cable Specifications . See Section 2.4 On-Screen Function Switches , page 2-6, to select Baud Rate. 3.1 Command and Status In the CLD-V2800 exter nal computer contr ol protocol, the computer transmits a command; when the player completes execution of the command, it returns an “R”. ASCII character codes are used for the actual commands and status responses. The command mnemonic is expressed as two ASCII characters. In most cases, there is no distinction between the use of uppercase or lowercase letters, and the use of uppercase letters is recommended. Arguments may be set to specify the frame number , speed or other values for a command. The argument is always placed before the command. The command is also used as the ter minator of the argument. In the simplest protocol, the player immediately executes one command as soon as the ter minator of the command line, a <CR> (carriage retur n), is received. Example: 1000SE<CR> : Sear ch to frame 1000. The player has a command buf fer that allows multiple commands to be sent from the exter nal controller in the same command string. Example: 1000SE 2000PL <CR> : Search to frame 1000, then play to frame 2000. In this example, when the <CR> is received, commands are executed sequentially from the first command of the buf fer . The “R” is retur ned to the computer after the play segment is completed. If a <CR> is sent before a command or command string has completed execution, the command is cleared and execution is cancelled.

R (received) <CR> <-<-<- 7) “Completion” Computer LaserDisc Player 1) “Search to Frame 1000”<CR> ->->->- 2) Search Execution Figure 3-A
See Section 3.5, page 3-7 & 8 for more infor mation about command for mats. In the command line, codes such as <SPACE> or <LF> (line feed) that do not affect player operation are ignored. The length of the command line is limited to the buf fer size. For the CLD-V2800 the length of a command string is limited to 20 characters. The <CR> or <LF> are not included in the buf fer size. When all the commands in a string are completely executed, the player transmits the “completion” message. (It sends an “R” <CR>.) If a n e rr o r occurs, an err or message such as E04 <CR> is retur ned by the player . This indicates the error occurrence, along with the error code. See Sec. 3.2 Error Messages, page 3-3. The automatic retur n of an “R” following command execution is called Automatic Status . Automatic Status is very useful when working with some computer programs, because it allows the pr ogram to know the appropriate time to send the next command. If this function is not used, the command pr ocessing time must be taken into consideration before the next command is sent. (T o set Automatic Status ON or OFF , see the Level III command for Communication Control on page 3-38.) 3.1.1 Request Status When an error message is received, it may be necessary to deter mine the player’s current status in order to continue a program. A variety of conditions can occur which may cause an error code to be sent. Since actual hardware failur e in the player is a relatively rare event, other conditions may be detected which would allow a program to recover and continue operation. Even when there is no err or , there are occasions when player status or disc infor mation is useful. In such a case, the Request Status function can be used. The user may want to find out the current frame number even if there is no error . Request Status commands can be useful under these conditions. On the CLD-V2800 players, some of the main Request Status commands in Level III are as follows: 1) To know the active mode of the player: ?P 2) To know the current frame, time, or chapter number for LDs: ?F, ?T , ?C 3) To know the current track, time, block index or p-block numbers for CDs: ?R ?T ?B, ?I or ?A NOTE: These and additional Request commands are described in Section 3.7.4 on page 3-31 through Section 3.7.7 on page 3-45.

3.5 Command Formats Level III commands on the CLD-V2800 are expr essed as “Command Mnemonics”, so they are easy to remember . “Command Mnemonics” ar e 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” expr essed 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 retur ned. 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 addr ess 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: CLD-V2800 Level III • Chapter Three CLD-V2800 Level III User’s Manual TP 120 v. 1.0 • 10/95 3-7 Frame number CA V : xxxxx N1 N2 N3 N4 N5 minimum = 0 0 0 0 0 » maximum = 65535 Chapter numbe r CA V , CL V xx N1 N2 minimum = 00 » maximum = 79 Time numbers CL V : H:MM:SS N1 N2 N3 N4 N5 (N1=hour , N2 N3=minutes, N4 N5=seconds) minimum = 00000 » maximum = 95959 Extended Time numbers CL V : H:MM:SS.FF N1 N2 N3 N4 N5 N6 N7 (N1=hour , N2 N3=minutes, N4 N5=seconds, N6 N7 Frame No.) minimum = 00000 » maximum = 9595929 Time CD N1 N2 N3 N4 N1 N2 N3 N4 MM:SS N1 N2=minutes, N3 N4=seconds, N5=blocks Block numbers N1 N2 N3 N4 N5 N6 N1 N2 N3 N4 N5 N6 MM:SS:BB Minutes 00-99, Seconds 00-59, Blocks 00-74 minimum = 00000 » maximum = 995974 T rack numbers CD xx N1 N2 minimum = 01 » maximum = 99 Index numbers CD xx-xx N1 N2 N3 N4 N1 N2 = T rack , N3 N4= Index T rack = 01-99, Index = 00-99 minimum = 0100 » maximum = 9999 Figure 3-F LD s CD s
Chapter Three • CLD-V2800 Level III 3-8 TP 120 v. 1.0 • 10/95 CLD-V2800 Level III User’s Manual 2) Integer — This indicates that the argument should be an integer number . The value is used to set a control register to some specified value or condition. N1 N2 N3 N4 N5 minimum = 00000 » maximum = 65535 NOTE: The maximum value used to set a contr ol register is 255. For details see Section 3.7.6 Register Control Commands , page 3-39. A Search command can accept up to the last frame, chapter or time number encoded on a LaserDisc. Maximum number of frames on one side of a LaserVision standard videodisc is 54,000 (CA V), Chapters, 0-79 (CA V or CLV), time numbers 59.59 (CLV). (One side of CLV disc holds one-hour of full motion video, time numbers can be encoded that describe running time of a program taking up several sides of several discs up to 9:59.59.) If a frame, chapter or time number larger than the last one encoded on a LaserDisc is entered, the player will sear ch to the highest number encoded on the disc and then enter Still (CA V) or Pause Mode (CLV). If a block, index or time number larger than the last one encoded on a CD is entered, the player will not execute the sear ch. 3) (Address) or (Integer) — When an argument, an address or an integer , is indicated in parentheses, it is optional and can be omitted. Command String — A command string consists of multiple commands. The maximum length of a command string is 20 characters and it is terminated by the <C/R> code (0D hex). Example: FR2000SE 2300PL <C/R> • After the ter mination, the command string is evaluated, and executed sequentially from the first command. • The <L/F> code (0A hex) and <SPACE> code (20 hex), even if contained in the command string, will be ignored because <L/F>, <C/R> and <SPACE> are not included in the number of characters which can be transmitted in the command string. • When an error occurs, subsequent commands in a string will not be executed. • If a new command string is input befor e execution of a current string has been completed, the remaining commands ar e cleared and execution is cancelled. Thus, in order to cancel a curr ently executing string, simply send the <C/R> without a preceding command. This does not cancel PA, SE, or RJ. • When the player is put into Spin-Up, Spin-Down or Search Mode, by external commands SA, RJ, or SE, subsequent commands issued will be executed and an “R” will be retur ned after the Spin-Up, Spin-Down or Search Mode cycle is finished, due to the player’s communication protocol. To check the player’s status, send a command to request status, ?P , ?D, ?T , ?R etc. To set player address flags send CH, FR, TM, BL, IX. If these commands are sent while the mode cycles are in pr ogress, the player will pr ocess the command, but won’t send a completion status.
3.6 Status Returns The player can retur n codes to the computer indicating certain status conditions: 1) Completion Message The completion message used in Automatic Status is “R”. R <C/R> 2) Error Message The error message is indicated by the letter “E” followed by a two-character error number . E N1 N2 <C/R> The error message occurs when the given command is non-executable and hinders continued control. A list of the error messages appears in Section 3.2 Error Messages , page 3-3 3) Request Status Return • In response to a single request command, the status is displayed as the appropriate character string with a ter mination code at the end. A ter mination code of either <C/R> or <C/R> <L/F> can be selected by using Register C. • If multiple request commands are sent to the player within the same command string, each status value is retur ned as the appropriate character string with a <C/R> (or <C/R> <L/F>) ter mination code. ?C?F<C/R> 02 <C/R> 10260 <C/R> • When the request command is at the end of the command string, “R” of the completion message is omitted.

4) Timing The timing from the receipt of a command to the retur n of the status value is as follows: • T1 is the time from the receipt of <C/R> at the end of the command string to the start of command execution, and is within a maximum of 20 ms. • T2 is the command execution time, and is at least 14 ms. T2 (before the <C/R>) increases depending on the type of command. • The minimum pr ocessing time for any command (total of T1 and T2) is 14 ms.

For mat: Integer S P Explanation: Contents of the Speed Register are rewritten with this command. Immediately, the completion status is retur ned. The active mode of the player does not change. This command is accepted even when Multi-Speed Mode is in ef fect. The speed parameter indicates the number of fields moved per second, and it is specified in range from 1 to 255. It is 60 (with a range from 45 to 90) for normal play. The initial value is 60. The relationship between representative play speeds and parameters is as follows: † These integers provide compatibility with LD-V8000, LD-V4400 and the LD-V2200. Programs written for the LD-V8000 or LD-V4400 using the “range of integers” in column two will play on the CLD-V2800/2600/2400 at the corresponding speeds in column one.

16) STOP MARKER LD/CD Function: Stop marker is set to the specified address. For mat: Address S M Explanation: The specified address is written in the Mark Frame/T ime/Block Register or Mark Chapter/T rack Register as indicated by the addr ess flag, and the completion status “R” is retur ned immediately. When the stop marker address is reached in Play or Multi-Speed, or Step Mode with a CA V Disc, Still Mode occurs; with a CLV disc or CD, Pause Mode occurs. In both cases, when the stop marker addr ess is reached, the stop marker is cleared fr om the mark register . The stop marker is also cleared when a step command is issued to step thr ough the address marker on a CA V disc. Here, the completion status “R” is r etur ned when the command is received and the stop marker is set, not when the addr ess marker is reached, as described in the Play command. Issue a disc location request command (?F ,?C,?T ,?R etc.) to deter mine whether not the stop marker address has been reached. I f a Clear or Reject command is sent before the stop marker is reached, the stop marker in the the mark register is cleared. The stop marker is functionally similar to the auto stop operation of the Play and the Multi-Speed commands. However , the auto stop and the stop marker retur n a completion status at dif ferent times. In an auto stop operation, the completion status is retur ned when the marked address is reached. In the stop marker operation, the completion status is retur ned when the stop marker is set. The stop marker command must be used when status r equests ar e sent to the player before the addr ess marker is r eached. It is also useful when the operation mode is changed befor e the marked addr ess is r eached.

3.7.6 Register Control Commands 45) REGISTER A SET LD/CD Function: Changes the current setting of Register A. (Display) For mat: Integer R A Explanation: Register A sets detailed attributes of the display. The CLD-V2800 has three types of display settings: Frame number (LD-CA V) or T ime number (LD-CLV , CD); Chapter number (LD-CA V or CLV) or T rack-Index number (CD); and User’s Display for user -generated messages, lines 0-9. Available combinations of the display settings are shown in the following table. Initial value is 3. All the character displays are tur ned ON/OFF by the display control command. The display contents are deter mined by Register A. * CD T rack and Index numbers are processed in the Chapter Register . CD Block numbers are processed as part of the time number in the Frame/T ime Register . The display positions on the screen for the CLD-V2800 are pictured below: CLD-V2800 Level III • Chapter Three CLD-V2800 Level III User’s Manual TP 120 v. 1.0 • 10/95 3-39 Integer Function User ’ s Chapter/ Frame/ T rack Time 0 Display Off 0 0 0 1 Frame or Time Number 0 0 1 2 Chapter or Track Number 0 1 0 3 Frame or T ime and Chapter or T rack 0 1 1 4 User ’ s Display 1 0 0 5 User ’ s Display and Frame or Time 1 0 1 6 User ’ s Display and Chapter or Track 1 1 0 7 User ’ s Display and Frame or Time, and Chapter or T rack 1 1 1 Figure 3-Q Figure 3-R Frame #(CA V) or T ime # (CL V LaserDisc or CD) Chapter #(CA V/CL V) or Track-Index # (CD) CLD-V2800 User ’ s Display - Lines 0-9 10 lines, 20 characters per line Register A Display Control o o o o o o o o
Line 0 is used for displaying chapter , frame, time and track numbers. Line 0 and 1 are sometimes used for displaying remote control inputs. Line 2 to 9 are used exclusively as the User’s Display Area on the CLD- V2800. If all lines of the User’s Display Area are requir ed for user defined messages, the 4RA command can be sent to the player . This will r eserve all lines (including lines 0 and 1) in the display for user messages. NOTE: Lines 0 & 1 are usually reserved for frame/time and chapter/track addresses and the address flag status. To activate the User Display Area: • Set the User’s Display using the Register A command. • Turn ON the display switch. (1DS) • Identify the line on which the characters will appear by using the Print Character command (PR) <CR>. (See page 3-30.) • Then send the character string to be displayed followed by <C/R>. NOTE: The display switch can be tur ned ON or OFF at any time. However , if Register A is changed so that the User’s Display Area is disabled, the contents of the User’s Display Area will be cleared. Also, if the Print Character command is issued before Register A is set for the User’s Display Area, the character string will not be seen. The Power -On default for display control is 3RA. This allows Frame/T ime, Chapter/T rack numbers to be seen when the display is turned on, depending on the type of disc that is in the tray. Register A may be changed for differ ent displays.

(Squelch Control) For mat: Integer R B Explanation: Attributes concer ning the squelch switch for video and audio are set in Register B. The squelch switch is normally controlled automatically in accordance with the operating mode of the player . In the modes where pictures and sound ar e not clearly played back, the squelch switch prevents the “noise” fr om being displayed or heard. (eg. During scanning on LaserDiscs, audio is squelched.) By rewriting the contents of the Register B, it is possible to make the squelch switch invalid. In this state, the video and audio signals ar e output continually. The initial value is 0. This operation must be fully understood before this function is used. Execution: * Disable the video squelch during searching. 128 R B 23000 S E 0 R B <C/R> R <C/R> * Play at 1/2 speed while outputting sound. 64 R B 30 S P M F <C/R> R <C/R> * Set to Still and retur n to nor mal squelch.

Independent Command Processor The CLD-V2800 player can be controlled by several dif ferent methods: From the Front Panel Buttons, the Remote Control Unit or Barcode Reader (Level I) or fr om an exter nal computer via the RS-232 port (Level III). An independent command processor inside the player assures the most appropriate operating environment is used. Because of this, the same commands may per for m dif ferently, depending on the control method. Most of the commands input to the player have arguments such as frame number , chapter number , time number , track number or various parameters. An argument storage area and an address flag indicating the frame, chapter, time, track, index or block number are provided for each contr ol method. Therefor e, arguments input for one particular control method do not af fect operations per formed with another method. Internal Player Components Address Specification Flag Register (computer control) This register indicates whether a particular address argument sent from a computer is a frame, chapter , track, index, time, or block number . Digit Buffer (computer control) This buf fer stores the numeric values of arguments sent from an exter nal computer . The contents of this buf fer ar e sent to the specified registers for command execution. Command Processor (computer control) This processor reads the contents of the RS-232C buf fer . It sends the arguments to the digit buf fer , or executes commands. RS-232C Buffer This is the RS-232C Input/Output data buf fer . Twenty-two bytes ar e used for input and another 22 bytes are used for output. Address Specification Flag Register (manual control) This register indicates whether the addr ess arguments are frame numbers, chapter numbers, time numbers or track numbers for nor mal contr ol operations. Digit Buffer (manual control) This buf fer stores the numeric values of arguments for nor mal control operations. The contents of this buf fer are sent to the specified register for command execution. CLD-V2800 Internal Player Controls C-4 TP 120 v. 1.0 • 10/95 Appendix C CLD-V2800 Internal Player Controls
