TASCAM CD-01U/CD-01U PRO RS-232C Protocol 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 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).

3.2. Machine ID

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