1. Overview
The DV-RA1000HD (here referred to as “controlled device”) functions can be controlled using a serial
RS-232C connection from an external device, such as a computer. Such a device is referred to here as
the “external controller”.

3. Command Format
Command Format Overview
Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8 … Byte n
LF ID Command Data 1 Data 2 Data 3 Data 4 … CR
The codes described here are transmitted in ASCII format (e.g. a command described as “23” is transmitted
as ASCII ’2’ followed by ASCII ’3’).
Uppercase letters are used for letters ’A’ through ’F’.
All commands must be prefixed by a line-feed (LF) character [0Ah] followed by a Machine ID.
All commands are terminated by a carriage return (CR) character [0Dh].
Sample commands
Sample 1: PLAY command (Machine ID=0)
When the controlled device is in STOP/READY mode, this command starts playback.
The PLAY command is [12], and it is transmitted using the following sequence:
ID Command
ASCII LF 0 1 2 CR
HEX 0Ah 30h 31h 32h 0Dh
Sample 2:Direct search for track 12 (Machine ID=0)
In order to perform this operation, “DIRECT TRACK SEARCH PRESET [23]” command is used.
The track number is also sent as a parameter (data). This is sent in four bytes, as shown below:
ID Command Data：12th track
ASCII LF 0 2 3 1 2 0 0 CR
HEX 0Ah 30h 31h 32h 31h 32h 30h 30h 0Dh
The four data bytes represent, in order, the following digits of the track number: the “tens” digit
(1), the “units” digit (2), the “thousands” digit (0), and the “hundreds” digit (0).
Machine ID
Machine ID of this device is fixed to [0]. A command with other Machine ID than [0] is ignored.

Command Sequence
The DV-RA1000HD does not have the “ACK” command for the each transport control command and data
preset command.
When a request command is transmitted from external controller to the controlled device, the controlled
device sends an appropriate return command.
When the mechanism status of the controlled device is changed (i.e. from stop to play), or an error occurs,
the controlled device sends a command to notify such change to the external controller.
Some samples of command sequence are described below:
Note that an interval of at least 20 ms must be left between commands.
Sample 1: Transport control (i.e. PLAY)
The controlled device is in STOP mode.
Send the transport control (PLAY) command from the external controller to the controlled device.
The controlled device starts playback and sends the CHANGE STATUS return command.
Command
External controller Controlled device Status of the controlled device
STOP
PLAY -> Starts playback
<- CHANGED STATUS Send the CHANGE STATUS
return command
Sample 2: To preset a data (i.e. PITCH CONTROL DATA PRESET)
Send the PITCH CONTROL DATA PRESET command with pitch control value from the external
controller to the controlled device.
The controlled device sets the pitch control data.
Command
External controller Controlled device Status of the controlled device
PITCH CONTROL DATA
PRESET (i.e. –1.0%) -> Sets pitch control data to -1.0%.
Sample 3: To request the status or a data currently set (i.e. PITCH CONTROL DATA)
Send the PITCH CONTROL DATA PRESET command with request data from the external
controller to the controlled device.
If the controlled device has the pitch control data, the controlled device returns the PITCH
CONTROL DATA RETURN with pitch control value.
Command
External controller Controlled device Status of the controlled device
PITCH CONTROL DATA
PRESET (with FF) ->
<- PITCH CONTROL DATA
RETURN

Sample 4: Get the status of the controlled device then go to next operation
The controlled device sends the CHANGE STATUS when the machine status is changed.
This CHANGE STATUS command is useful for checking the current machine status by using the
MECHA STATUS SENSE command.
This example describes that checks the Record Ready status then starts recording.
Command
External controller Controlled device Status of the controlled device
STOP
RECORD (Record Ready) ->
<- CHANGE STATUS Send the CHANGE STATUS
return command
MECHA STATUS SENSE ->
<- MECHA STATUS RETURN Send the Record Ready status
PLAY(Record) ->
<- CHANGE STATUS Send the CHANGE STATUS
return command
