Outline
This document explains in detail the interface specifications, the protocol and the command specifications relating to the connection of this device with an external equipment (hereinafter called Host) via RS232C. When USB is selected from the menu REMOTE I/F of SETUP MENU of this device, operations from USB will also use the same protocol.

Output level Power ON : +5V or more Power OFF : -5V or less Connecting cable Please make sure to use a crossing cable when connecting this device to Host. Because the RTS/CTS control on this device is not used (i.e. short-circuited), this control on the Host side must be disabled, or the pins 7 and 8 must be connected as shown by the dotted lines in the above figure.

Command Overview
4-1. Communications Protocol Transmission is done in byte unit. At first, Host sends one byte, and waits until a response is obtained from this device before sending another. The response from this device can contain one byte, or a plurality of bytes like the CTL data. Moreover, for a command like EJECT that usually requires a long execution time, in addition to an ordinary response that is returned immediately after the receipt of the command, there exists another response that denotes the execution result when the operation is completed. According to the RS-232C protocol, commands, changes of this device, and parameters will be all defined as commands. For further details, please refer to “5. Detailed description of commands”. Some simple examples are shown below. 1. Commands used to control this device (1-byte response is returned from this device) The case of a command having no parameter : Command Host

Completion of operation
There exist 3 responses from this device, which are COMPLETE, NOT TARGET, TRAY OPEN. COMPLETE ... to be returned when a command is executed and ended normally. NOT TARGET ... to be returned when a specified target is not found. TRAY OPEN ... to be returned when the disc tray is open 4. Each command is basically 1-byte long, but there are some which are the combinations of 2 different commands.

m 1) Before receiving a response from this device, you shouldn’t send any other command. However, if there is no response from this device for more than 10 msec after sending a command, it is necessary to take some measures because the transmission could have not been done correctly. 2) No other command can be inserted between an extended command and a secondary command.

Detailed Description of Commands
5-1. Response Command This is a command to be sent from this device after receiving a command from Host. Below are the commands supported by this device.
5-1-1. COMPLETE (01H) COMPLETE is returned when the execution of a SEARCH, REPEAT or MEMORY SEARCH command is completed. However, during the execution of any of these commands and before COMPLETE is returned, if another DVD editing command or CL command is newly received, the current execution will be cancelled and since the new command will be executed, COMPLETE will not be returned.
5-1-2. TRAY OPEN (03H) This command informs that the disc tray was opened by the EJECT command or the pressing of the OPEN/CLOSE key of this device.
5-1-3. NOT TARGET (05H) This command informs that the specified time data or CTL is not found in the disc during the execution of a SEARCH, REPEAT or MEMORY SEARCH command. In this case, the execution will be discontinued.
5-1-4. ACK (0AH) This command is returned when a defined command is normally received. However, for STATUS SENSE commands that make requests for data, not ACK but only data will be returned. At that time, even if a command could not be executed (e.g. the case of PLAY command with the disc tray being open), ACK will be returned.
5-1-5. NAK (0BH) NAK is returned when a command that is not defined in the current mode (e.g. a numerical command in a mode other than numerical input mode) or a command that cannot exist in the numerical input mode (e.g. the PLAY command) is received, or when a transmission error is detected.
DVO-1000MD

5-2. Numerical Command This command is used to specify numerical parameters. It is used also to return a numerical data such as time data and CTL from this device. There are 3 formats available (byte-parameter input, multi-byte parameter input, multi-type parameter input) as shown below. Byte-parameter input This is used to specify a 1-byte numerical parameter. NAK will be returned if a non-numerical command is entered. FWD SHUTTLE and REV SHUTTLE commands belong to this type. Ex) Double speed playback Host

“ACK”

Multi-byte parameter input This is used to specify a multi-byte numerical parameter. Such a numerical parameter is composed of a plurality of bytes including a sign code, and is always ended by ENTER (40H). Each command has a fixed maximum number of bytes, and when this value is exceeded, the numerical part that comes behind is valid. However, the sign command is given a special treatment. CTL PRESET and SEARCH commands belong to this type. Ex) An example of setting the preset value of CTL to “0:12:34:12”

Multi-type parameter input This format is used to specify a plurality of numerical parameters separated one by one by an ENTER code. Each numerical parameter is similar to a multi-byte parameter. INDEX SEARCH, SEARCH TO TARGET TIME and REPEAT commands belong to this type. Ex) An example of setting the preset values of REPEAT to Title 2, and “0:12:34:12” (to be repeated 10 times).

n When a numerical parameter is used with the multi-byte parameter input format or the multi-type parameter input format described above, the lastly entered number can be erased by using the C.E. command. Moreover, both the sign and the number may need not be entered, and when omitted, “+” and “0” will be respectively assigned. If a number is entered with fewer digits than pre-determined, high-order digits are considered omitted. When it has some extra digits, then the extra high-order digits will be eliminated and the remaining digits represent the valid value. Here, the sign is not included, but it is always given a higher priority. When a sign command is used, a keyed-in sign will clear out all previously entered numbers. Furthermore, since a sign cannot be erased by C.E command, if it was wrongly entered, a new sign together with all other numbers would need to be re-entered. Ex) Some input patterns of CTL data are shown below _ 0 1 2 4 C.E. 3 4 5 2 ENTER results in _0:12:34:52 ENTER results in +0:00:00:00 2 3 1 0 ENTER results in +0:00:23:10 _ 2 1 2 3 4 5 4 3 2 ENTER results in _2:34:54:32 _ 1 2 3 4 + 1 0 ENTER results in +0:00:00:10 DVO-1000MD

5-2-1. Numerical Commands 0 to 9 (30H to 39H) They denote respectively the numerical values 0 to 9
5-2-2. SIGN PLUS (A1H), SIGN MINUS (A2H) They are used to add a sign (+, _) to a numerical value.
5-2-3. ENTER (40H) This is used to mark the end of an entered numerical parameter.
5-2-4. Character Commands A to Z (41H to 5AH), a to z (61H to 7AH), SPACE (20H) They denote respectively characters A to Z, a to z, and a space. They are used in commands such as SET DISC NAME, SET TITLE NAME, and SET TITLE INFO.
12
DVO-1000MD
5-3. All-purpose Control Commands 5-3-1. C.E. (41H) This is used to suppress an error status or to delete a single character lastly entered. This command however cannot be used to erase an entered sign. In order to do that, please use a sign command to enter a new sign for replacement. For more details, refer to “5-2. Numerical Command”.
5-3-2. C.L. (56H) This is used to cancel an error status, and at the same time, to cancel the current command in changing the mode of this device to PLAY PAUSE. After sending a command having a numerical parameter, and before this numerical parameter is fixed, if a C.L. command is entered, the entry of this numerical parameter will be stopped and the sent command will be cancelled. In the case when the repeat number of REPEAT command is set to “0”, an endless playback will be made until this C.L. command is entered.
5-3-3. EXP-1 (D8H), EXP-2 (D9H), EXP-8 (DFH) EXP-1, EXP-2 and EXP-8 are the 1st, the 2nd and the 8th extended commands. They will become effective only when used in pairs with their secondary commands. However, if there is another command that is inserted between an extended command and its secondary command, this extended command will be cancelled and NAK will be returned. Ex) The KEY INHIBIT ON command is normally executed
