1. Overview

The CD-01U/CD-01U PRO (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”.

2. Specifications

3. Command Format

3.1. 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 command s

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).

3.2. Machine ID

Machine ID of this device is fixed to [0]. A command with other Machine ID than [0] is ignored.

3.4. Command Sequence

The CD-01U/CD-01U PRO 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

PLAY -> Starts playback

CHANGED STATUS Sent the CHANGE STATUS

<-

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

PITCH CONTROL DATA
PRESET (i. e. –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 [FF] 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.
